The Best Water Filters: A Review
There are a lot of misleading claims about water filters. Many filters are marketed with general statements like “improves taste and odor”. But filter manufacturers don’t mention the specific amount of pesticides or chloramines removed, for example. Government websites also tend to leave out important data on water contaminants — it’s not in their interest to point out the problems with municipal water. We’ve found the best reviews of water filters comes from independent experts.
The best books on water purification I’ve found are The Drinking Water Book by Colin Ingram and Don’t Drink The Water by Lono A’o. Ingram suggests that one should first discover which pollutant are in your local water supply. You can then customize your filtration by selecting filters that target those specific pollutants. For example, if are you in a region of the U.S. where radon and uranium is commonly found in the groundwater, choose specific filters to remove those radioactive pollutants.
There are many sources of water contamination (see the graphic below), and sophisticated water purification is simply not possible on the massive scale that municipalities have to deal with.
Potential Sources of Water Contamination
Here’s the list of types of contaminants you want to remove from municipal tap water:
- Organic compounds (Pesticides, Herbicides, Pharmaceuticals, Fuels, etc.)
- Toxic metals (Lead, Mercury, Aluminum, Cadmium, Chromium, Copper, etc.)
- Bacterial and viruses (Giardia, Cryptosporidium, etc.)
- Radioactive substances (Radon and Uranium, etc.)
- Additives (Chlorine and Chloramines, Fluoride, etc.)
Ingram’s book also contains a comprehensive collection of water filter reviews. He rates filter from “Acceptable” to “Excellent++”. Here are the ratings:
- Pitcher Filters (Acceptable)
- Faucet Filters (Acceptable)
- Countertop Filters (Good)
- Under-Sink Filters (Good to Very Good)
- Reverse Osmosis Countertop Purifiers (Good to Very Good)
- Reverse Osmosis Under-Sink Purifiers (Good to Very Good)
- Countertop Distillers (Excellent to Excellent++)
- Whole House Filters (no clear answer, but appears to be mostly “Very Good”)
Notably, all the pitcher-style filters and faucet-mounted filters get a rating of “Acceptable” (the lowest rating).
Countertop Water Filters
There are dozens of brands of countertop filters, and many are made to high manufacturing standards. However, the cost of replacement filters can be high. So countertop filters with standard 10-inch cartridges are recommended. Ingram says: “The availability of a wide variety of standard cartridges allows consumers to customize a water purifier for specific water conditions and to purchase cartridges from a competitive array of suppliers.”
Recommended countertop filters with 10-inch cartridges: Superior Water Filter System, Puriteam (formerly Puritech) and Aquatic Reef Countertop. They are available from Amazon.
Under-Sink Water Filters
Under-sink filters tend to tend to have space for two or three different filter types, which is important if you want throughout filtration. Look for those filters that accept standard 10-inch cartridges.
Based on our research, the best performing water filters for your money are:
- The Triple Undersink Filter ($199) and the Enhanced Performance Filter by Pure Water Products (starts at $300)
- The PurHome UCT by Puriteam ($299)
Countertop Reverse Osmosis Purifiers
Reverse Osmosis Countertop Purifier
Countertop reverse-osmosis filters are full-size, multistage systems with performance that approaches or equals that of under-sink reverse osmosis units. Recommend models are Reverse Osmosis Filter by Pure Water Products and TGI CT-445 by Topway Global Inc. These filters have four stages: a sediment filter, a granular carbon filter, an reverse osmosis membrane, and a final granular carbon stage.
Under-Sink Reverse Osmosis Purifiers
Watts Reverse Osmosis Under-Sink Water Filter
There are hundreds of brands of under-sink reverse osmosis systems. Under-sink units generally perform better than counter-top reverse osmosis units, because they employ booster pumps and allow the reverse osmosis membrane to function optimally.
Recommended systems are: Watts Reverse Osmosis Systems, the Enhanced Water Filter by Pure Water Products, Rioflow USR04-50, TGI WIN445, and the Puregen ERO-535.
Gravity-Fed Drip Filters
British Berkefeld Ceramic Drip Filters
If you are looking good filtration on a budget, I recommend a gravity-fed drip water filter system like British Berkefeld. These filters range in price from $200 – $250. They require no electricity to operate — water is filtered as it drips from the upper chamber to the lower chamber. Because the water is filtered slowly, the filtration is much more effective than a faucet-mounted filter. Berkefelds use “candle” type filters, which are widely available and can be customized to your specific filtration needs. Another advantage of this filter is that it can be collapsed and taken with you when you go on vacation.
Available from Amazon, see also the fluoride version.
Countertop Distillers
Countertop distillers are effective water purifiers, but they take some time to distill water (for example 5 hours to distill 1 gallon). They also give off some heat and the integrated fans make some noise.
Countertop distiller that get a rating of “Excellent” are the Megahome Countertop Distiller, Waterwise 4000 and Waterwise 8800, Kenmore 34480 and Pure Water Mini-Classic.
Megahome Countertop Water Distiller
Megahome Countertop Water Distiller / Filter
This distiller is sold under many brand name, and it’s the most widely distributed distiller in the world. It has many quality components despite being inexpensive. It produces 1 gallon of water in 5 hours. The water is passed through a small granular carbon filter. There’s a sealed connections from the distiller to the water collection container, so there is minimal risk of contamination by air. The unit has a stainless steel boiling chamber that is easily accessible for cleaning.
The Megahome Countertop Distiller is available from Amazon for about $150.
Waterwise 4000 Countertop Distiller
Waterwise 4000 Countertop Distiller
This is a more powerful version of the distiller listed above. It has the same features but produces 1 gallon of distilled water in 4 hours. Also received an “Excellent” rating.
The Waterwise 4000 is available from Amazon for about $280.
Waterwise 8800 Water Distiller
Waterwise 8800 Water Distiller
The Waterwise 8800 is an inexpensive high-quality distiller. It produces 1 gallon of water every 4 hours. It received an “Excellent” rating from Ingram.
The Waterwise 8800 is available from Amazon for about $280.
Pure Water Mini-Classic
Pure Water Mini-Classic Distiller
This rugged distiller is built out of stainless steel. It weighs 24 pounds, the filter housing is also made of stainless steel so there’s no contact with plastic.
The Pure Water Mini-Classic is available from Amazon for about $600.

Great review Justin thanks.
Just wanted to point out the reverse osmosis systems reject (i.e. waste) more water than they filter.
That doesn’t sound to efficient – unless we could figure a way to use this grey water say for shower or clothes washing.
Anyone hooked up a system like that?
Todd
I’ve read that it doesn’t matter how superduper your water purifier is, pollutants get in through the back door. The back door being your shower nozzle. Supposedly you absorb the waterborne toxins thru your skin.
But i’ve never been able to substantiate this. Can anybody out there verify or debunk this claim?
I’ve never bothered to reply to anything here before but this article is just…GRR!!!
All those countertop distillers you’ve listed are most certainly NOT efficient! They are all energy hogs since they work by boiling water and then condensing the steam. And you’ve totally ignored the potential health issue they pose since they remove all the healthy minerals from the water that are needed for good bone health etc. If you’d mentioned just one solar still I’d have not been so appalled by the list of energy pigs.
Thanks to Todd I’ve no need of adding an additional rant over the inclusion of reverse osmosis water pigs!
Aside to marinus:
http://books.google.com/books?id=FsTJIOgt3RIC&pg=PA593&lpg=PA593&dq=skin+absorption+of+water+contaminants&source=web&ots=hEj_X-lRsq&sig=tPidmVtQQnzGIouq0r1cSwbtQG0&hl=en&sa=X&oi=book_result&resnum=1&ct=result
If the link doesn’t work just google “skin absorption of water contaminants”. For that reason the truly metaefficient choice would be the appropriate whole house filter with perhaps an additional undersink passive filter as a backup.
marinus and brivari:
This site reviews products based on their meta-efficiency. Energy efficiency is only one factor in this assessment.
I stated that using rain water is the most efficient way to obtain pure water. It requires some filtration but not as much as ground water sources. However, it does require an expensive installation to retrofit an existing house.
Whole house filters are good. But as far as I’m aware they cost over $4000 to install. Affordability is an important in my assessment.
Distillers do use electricity, but they are effective and inexpensive. I also mention a non-electric distiller. They could be powered by renewable sources like biogas or even wood.
Distilling does remove minerals from water, but this is not particularly important — we get enough minerals from fruits and vegetables.
Solar distillers are inconvenient and the water does not get sufficiently hot from solar power alone. They should actually be called solar evaporators. They also get contaminated because they are not sealed.
Most reverse osmosis units do waste water. But recirculating RO units are more efficient, and the waste water can be re-used as like any other greywater.
I’ve yet to hear any efficient alternatives to the filters I list. Keep in mind that comprehensive filtration and affordability are important.
My husband needs to use distilled water for his sleep apnea machine. We’ve been buying bottled water for months, and I’m feeling guilty about the amount of plastic bottles we’ve gone through. I don’t plan to drink the water from the distiller we got, but I’m happy to have it now
i know what you mean, i have sleep apnea and it’s so difficult to clean the part of my machine where the water is held because of the buildup after so long, in the beginning i just used tap until we figured out what was going on… i live in a third world country now tho, and all i can use is a distiller so i wont have to deal with the pain in the butt of having to clean out that contraption! =]
Ok –
Marinus and Brivari –
I will try and comment on toxins absorbed thru the skin – I am by no means an expert but I am a doctor (allergist) and have a B.S. in Biochemistry so I know some about the partition coefficients mentioned in Brivari’s google book link.
I have seen these filter showerheads sold on green websites for preventing toxins absorbed thru the skin. Chemicals definitely can be absorbed thru the skin. There are common medicines given by way of a transdermal patch system (think nicotine patch – birth control patch – clonidine patch and others.)
However remember in those examples you have a high local concentration of a pure chemical that is lipophilic (which is important because this only works for lipophilic things because only they get absorbed thru the skin (the cell walls of the skin are made of lipid membranes so to pass thru these a chemical needs to be lipophilic.))
Then recall that lipophilic things do not dissolve in water. They float on the surface (think oil slick).
Most of the data referred to in the google book link talks about bathing under a toxic “octanol” layer. Where as most people shower instead of bath.
Perhaps a toxic water filter is more important for bathing than showering.
Then also the book link talks about non human systems (rats) bathing not showering. Remember also that smaller things (rats) have a higher surface area to volume ratio and therefore abosrb toxins thru the skin easier. There were reports several years ago of toxicity from applying chlorhexidine to the skin but they were mostly in children because of the SA/vol ratio.
So in summary – although toxins can be abosrbed thru the skin and should be studied I think people shouldn’t be too worried because:
1. only lipophlic toxins can work this way.
2. the data mentioned here is for bathing – whereas most people shower.
3. the data mentioned here is for small mammals (high SA/vol)
I’d like to see some adult human data on toxic levels of things present in the blood after only a regular tapwater shower before I’d worry.
And remember – All toxicity is dependent on dose. We all have PCB’s in our body – hopefully just too low of a dose to matter. So even if they could measure toxins in the blood from showering it wouldn’t mean much unless they showed they hit a critical level.
Final thought – sunlight causes cancer – so if we want to avoid every possible carcinogen you either have to live inside all year.
Hope this helps – feel free to differ.
Todd
Hello.
A very sensible and very clear explanation for shower water. But, do you have any comments on swimming pool water? The best managed public swimming pool is full of chemicals, while the not-so-well-managed can be ………I will appreciate your comments. Some years ago I stopped going to a public swimming pool because of some rather unusual water (un)management techniques and concern for what happened at the skin interface. Some days you could even see mounds of powdery chemicals lining the bottom of the pool, which nevertheless still had cloudy water. That started me thinking and soon the decision was to forget about the swimming.

>Distillers do use electricity, but they are effective and inexpensive.
I have to disagree with this reasoning, Justin. The same could be said of incandescent lamps.
According to my calculations, purifying 1 gallon of water with a distiller would use 2.75 kWh of electricity. If you made a gallon of water a day, that would be 1000 kWh/year for water purification *alone.*
Nathan,
Consuming electricity is better than drinking polluted water. If your electricity is coming from a dirty source, that is a different issue.
Also, I point out in the article and in the comments that using rain water is the best solution.
You don’t provide any solutions yourself.
Justin
Well said Justin, your article is very informative and makes a lot of sense. I have been searching for more efficient ways to get cleaner water and I’m definitely going to be trying out some of the counter-top distillers. The only problem I have with this is that my electricity does come from a dirty source, though I am also reaching towards that goal of living a life completely free of any kind of environmental pollution. I think this is a goal that everyone should have.. we need to be working to save our planet, especially in times like these.
I wont mind electricity if it means health for my entire family.
Guys nice review and conversation. How about Aquasana filters? I ve found several websites mentioning them as one of the best around, not if they are just bogus. Could you provide some insight? Thank you
Aquasana seems ideal. It only takes out part of the fluoride, about half. The water tastes great! It’s cheap and easy in all ways of installation, filter change, usage.
Would really appreciate your taking a look at it. I am thinking about ways to remove more of the fluorine at this time.
Thanks for a great job.
J. Howell
Jstin,
Nice article!
Reverse Osmosis,
If what you are using /doing in life (if it means health for my entire family.) causes harm to others, your family will aslo not benefit from it in the long run.
Regarding brivari’s concern about removing minerals from the water, the human body does not get it’s supply of minerals from water. Even with the most mineral laden waters in the United States, you would have to drink more than 60 gallons per day to absorb any beneficial amount of minerals. And that amount of water would overload your kidneys and cause water intoxication, which can be fatal. A healthy diet will supply all the vitamins and minerals the body needs.
I use distillation, hooked up to an array of solar panels. Am I “wasting” energy? I suppose you could say that. I could eat raw food and drink from rain barrels, but I prefer to find sustainable ways of creating energy to cook and produce healthy drinking water. I agree that distillers are not efficient, and even if they were built more efficiently, they still use a lot of energy. But if you buy clean/renewable energy, the impact is minimal, and the pure water is inexpensive (20-30 cents /gallon typically). I keep my distiller in the garage during summer and in the house for winter. I capture all the heat it generates in winter this way. Although it is little, it’s better than heating the garage.
Tim,
I wouldn’t lose too much sleep over the energy use. CO2 is a tiny molecule that makes up only 0.034% of the earth’s atmosphere, and despite its increase in the atmosphere, the earth has been cooling for over a decade, which will likely continue for a couple decades more:
http://news.bbc.co.uk/2/hi/8299079.stm
Furthermore, it has been revealed that a significant amount of the weather stations that showed warming were not in their prescribed geographical location, and that many suffered from human development warming bias:
http://www.timesonline.co.uk/tol/news/environment/article7026317.ece
Add to that the scandal of faked climate data and the debunking of many of the original tenets of human-caused (anthropogenic) global warming (AGW):
http://www.timesonline.co.uk/tol/news/environment/article7004936.ece
On top of the empirical evidence, the scam of AGW can be clearly seen in no other than Mr. Al Gore himself, who, despite having a carbon footprint >30x the average US citizen (probably thousands of multiples of the average human CO2 footprint), he has increased his claimed net-worth from 1-2 million to 100 million in the last decade.
Intellectually, scientifically, economically, and using common sense, AGW is clearly a scam.
The irony, and tragedy (other than the blatant power and money grab of the powers that be), is that it takes so much attention away from real environmental problems: habitat destruction, invasive species, destruction of resources (e.g. declining fisheries), and so on, which are NOT fixable.
But I’m afraid that too many people have already been duped into investing emotionally into the belief that CO2 is the enemy.
Hi,
I came across your site and have a question. Our tap water was resently tested and was contaminated with lead and copper.
Lead is 0.006mg/L and copper actually has 2.12mg/L.
I’m searching for a good filter system to remove these contaminants.
I know there are lots of filters around but I need to make sure that
it actually works. Whould a carcoal filter be enough to remove above contaminants. Or do we need another filter system?
Any suggestions are appreciated.
Thanks!!!!
Hi,
I’ve been looking at water filters as well, thanks for the article! However I am confused about your past good review of the Berkey. I was leaning in that direction. How does the Big Berkey or British Berkefield compare to these new filter systems you’ve reviewed?
I have both chloromines and fluoride in my water. Thanks!!
I was wondering the same thing.
Can someone please advise?
Thanks!
After using a few different systems over the years the best combo I’ve found is: For the faucet I use a triple ceramic membrane filter from crystal quest. Its cheap for how much it removes and is easy to hook up. Good for washing youre face, brushing teeth, plants ect.
For drinking and cooking I use a steel megahome distiller. Using the fuacet filter water will remove the VOCs before I put the water in the distiller since distillers dont remove VOCs (prefilter). The bottles for the megahome distillers stink though so dont buy extras. Cleaning the gunk out of the distillers will require steel wool and muscle so dont give one to granny.
For the shower I use a sonaki vit. c with a sediment filter that they sell.
Have had good results with this so far (2 months). You can see through the sediment filter housing which is cool. It started turning green after the first shower due to the chlorine and gradually turns dark grey from the dirt. Much softer hair and skin.
sonaki showerhead rusted on the inside. avoid sonaki. try others.
I understand the rationale for being unhappy with the waste of reverse osmosis systems. However they are popular here in west Texas for a reason–the municipal water does not taste good, and while we are assured that it is safe, there are issues with using it (i.e. iced tea comes out cloudy and unappealing, with sediment at the bottom of the jar). Other places that I have lived do not have this problem, which is why many opt for r/o systems, or to go and buy drinking water. Obviously the water we have is not a problem for bathroom or even most cooking purposes, though garden and houseplants don’t like it much either and tend not to do very well at all.
After 4 years of trying to manage with the municipal water, I am about at the point of trying to do something more proactive–I am also concerned that all the minerals in the water will increase my chances of another kidney stone, something I’d sure like to avoid.
The idea of a countertop r/o system seems more efficient than an undersink model since this way one can do r/o only as needed. Does anyone know if any of the choices can handle the really hard water that we have here?
thanks!
I was interested in possibly purchasing a reverse osmosis system, but am hesitant because of the wasted water and some information from Aquasana (whose ‘whole-house system’ I am also considering purchasing) Aquasana says that reverse osmosis leeches minerals but also makes the water acidic–not what you want for you body! They also said when you drink reverse osmosis water, as it goes through your body, it takes your body’s minerals with it, as water is always trying to get back to it’s ‘natural’ state. I have not had much success trying to find info comparing the processes–any thoughts anyone? Thanks!
Stephanie, Distilled water is a solvent. RO with carbon filtration does not get all bacteria and arsenic and will not remove viruses. However, distilled with carbon filtration will get everything as long as it is maintained properly and filters are changed according to instructions.
There is concern about losing minerals. Yes, we should be getting our minerals from fruits and vegetables but the reality is #1 most people don’t consume the RDA (recommended death allowance) of fruits and veges on a daily basis. #2 Even organic fruits and veges that have shown in tests higher concentrations of minerals are vastly devoid of mineral content compared to 50+ years ago.
So my wife and I have come up with a solution that works for us—We distill water and add back natural minerals via Himalayan Rock Salt. My wife soaks the natural rock salt in water and adds a teaspoon per gallon to distilled water- in effect re-mineralization the pure water.
Now it’s one thing to guess how this works but we went a step further. We went and had a bone density scan to see how the minerals were influencing our bodies. Both my wife and I had excellent bone density from our Dexa Scans. We have also run nutritional test via Metametrix to determine how we are processing minerals and how all of our organs, pathways are working…. So scientifically we are able to verify our health status, not just based on how we feel. Because many people feel good, but that doesn’t necessarily mean they are healthy.
Overall, the life of the flesh is in the blood…so when we provide the right nutrients and pure water with the right balance of minerals, we are doing our bodies good. My personal feeling is that much of our contaminated water, air, food is contributing to overload on our detox organs—liver, kidneys, gall badder, skin—thus contributing to many forms of cancer. But if I had to pick one thing from a physical perspective we could for our bodies, it would be drinking pure water. Take away food, exercise, etc..and you have water. Do you know why? People can live without exercise, although not to a high quality of life. People can live for a certain period of time without food, although at some point they will need nourishment. But we can only live just a few days without water. Water is key to life and my #1 recommendation.
Hi Justin,
I’m a filter newbie and this is the best thing I’ve found online to help guide me. For a number of reasons, I’ll probably stick with an undercounter one. Can you tell me if Ingram rated any of them “very good” ? Do you have a recommendation, especially re single, twin, triple, etc – especially between Pure Water Products and PuriTec?
I appreciate any help, thanks!
Hi Justin,
I’ve got the same question as Carol…there were so many models/choices that it would be really helpful to have a rec. on a specific model?
I looked up info. on Aquasana and although their filteration seems to be good there we a lot of complaints about leaking (in their undercounter unit) which seems to indicate that there is a problem in the quality of their housing unit (I saw the reviews on Amazon).
Thanks for the great website:)
Nina
Nina and Carol,
Ingram gives under-the-sink filters a “Good” rating mostly. He gives a “Very Good” rating to the Triple & Quadruple Undersink Filters by Puritech and Pure Water Products. He says those filters have “great performance and value”.
Specific models:
Quadruple Undersink Super Filter by Pure Water Products LLC
Puritech UCT
Triple Undersink Filter by Pure Water Products
Justin
Justin,
Thank you so much. Your site is wonderful, I felt so lost before I found it.
Carol
Justin,
Thank you…I think I’ll buy a system this week. Before I do, I have to admit to being curious as to why you chose the Big Berkey for home use. It seems to have great reviews but I can’t figure out why it’s a better choice over an undercounter system (which is for obvious reasons more convient to use). Would you mind sharing why you chose the Big Berkey?
Thanks again,
Nina
we have a berkey. it uses no power other than manually dumping water in the top. but if our water supply stopped providing us water we could filter water out of our rain barrel or local stream for that matter. an endless supply of emergency water is a comfort to us.
k-)
Nina,
Glad I could help. I’ve updated the review with the new information.
I chose the British Berkefeld system a few years ago because it didn’t involve and installation and it was the least expensive option.
Justin
Justin,
How is the cleansing process when using an Ozonator? I bought the ozonator you recommended and i filter my water through the tap (Brita) and then Ozonate. Do we know how effectively this will take out any toxins?
Matt
Hello Justin,
I have been told that the copper piping for my water system might be causing some of the health issues I have had and that I should get an RO system. Is that the only way to remove copper? Are there other systems that also remove copper?
Thanks
With all this talk about water filters, have we thought about boiling the water? Isn’t that a simple way to remove everything from the water?
Also our bodies are very strong and having certain things in them to help our immune system to become stronger, so then we can fight off stuff like this.
But I do understand about the shower, I think about that every time I get in there. But I remember if I have soap and exercise, all those toxins are removed from my body!
And whenever the weather gets better, I will get back into the sun because it is a natural powerful source of Vitamin D!
Solar Iphone Charger If you want to check it out please do, if not thanks for reading my comment!
I ordered a counter top filter system from Crystal Quest. The unit leaked. I called them and had a terrible customer service. They acknowledged the problem, but they said I would have to pay a 30% restocking fee on the product even if it’s defective. I would go for any other brand but not Crystal Quest! It’s a rip off!
I wonder whether everyone needs a water filter? Here in Portland, Oregon, the water is the best I’ve ever tasted, but does good taste equal pure water?
I think the criteria for the most metaefficient water filter should be the one which removes the most contaminants (pesticide, benzene,heavy metals) but at the same time retains the essential minerals/ nutrients in water.
Distilled water is NOT for long term drinking. The human body needs minerals like Calcium, fluoride, etc. That is why in hospitals, IV fluids have NACl in it.
Imagine what will happen if you infuse distilled water in your veins.
Although there are other source for this minerals in food, the most basic and essentially “free” source is our water supply.
With that… Distilled water is OUT as a drinking water source…
To get the most metaefficient water filter, we should check their efficiency in removing the contaminants. The NSF test the “claims” of the manufacturer and certify their water filter system…
http://www.nsf.org/certified/dwtu/
You can see the percentage of removal of contaminants posted in the nsf website or the manufacturer’s website in the nsf links. (As you can see in the website, there are a lot of water filter system available out there)
Ergo, the most metaefficient is an NSF certified product which removes the most contaminants and retain the essential nutrients/minerals.
There are websites which compares their efficiency in removing contaminants such as these…
http://www.waterfiltercomparisons.com/water_filter_comparison.php
I have yet to see a website which compares all available water filter in the market.
I hope metaefficient can research on this…
I’m sorry, but that is just plain wrong. The amount of nutrients in any water is miniscule. You want to replace the minerals you lose by drinking a glass of distilled water?: lick your arm. The reason hospitals give .91% saline is that it is the same salt concentration as the body and is thus safe to give quickly and in large amounts. Dont worry, if you drink too much of any type of water, youre posterior pituitary will release less anti-diuretic hormone and youre kidneys will produce more dilute urine.
Distilled water is perfect, and if you want, add some minerals for taste, particularly if youre going to use it to make some good tea.
The minerals can be added back to the water, which does improve the taste, if nothing else. Also, I don’t see how a filter could selectively remove everything but trace minerals.
ECOLOBLUE is the best thing ever…
It is expensive but worth every penny..
This web site is run by the parent company of Aquasana which is NOT an NSF certified filter:
http://www.waterfiltercomparisons.com/water_filter_comparison.php
So you might want to look at that with a grain of salt?!
Many of these recommended water filters above are NOT NSF certified. NSF is the non-profit body which certifies if a filter takes out what it SAYS it takes out of the water, so if you buy any water filter make sure it’s NSF certified, (not just “tested according to NSF standards”) so that you know it does what it says it does! Aquasana and many of the others above are not NSF certified for 053 Health Standards which means they take out unhealthy contaminants!
One of the best contaminant removers on the market is Multi-Pure. Multi-Pure removes over 65 major water contaminants.
However, if you want to remove arsenic you have to get a reverse osmosis system. While Multi-Pure and others do make an NSF certified reverse osmosis system, I do believe that RO systems waste water and the water you end up drinking is “dead” water, water with all healthy things removed along with the unhealthy things.
I’ll take my chances with arsenic and radon and live with a Multi-Pure carbon filtration system which takes out MOST contaminants (certainly more than any other carbon filter).
Multi-Pure does make a water filter that reduces arsenic. Here is a link to the countertop model CBASSC:
The model 88OSSC on the multipureco.com website is one of the models, and you can find more.
Go to above and see varieties that reduce arsenic and other poisons.
Sorry, the above comment does not show the web links that I pasted in to it. The first link was to the model mentioned, CBASSC at bestfilters.com and the second is named, as multipureco.com. Go to Multi-Pure and check them out – a bunch of varieties – countertop & under sink.
