In considering how to make sure you buy the Best water filter, it is important to read water filter reviews and compare water filters, as well as examine the facts. Fortunately any water filter worth buying tells you - in the fine print in some cases - exactly which contaminants are reduced by their filter. By digging up these "data sheets" we can then easily compare which filters reduce which contaminants and thus determine which one removes the most contaminants. (I've done that for you, below!)
When you choose a water filter the most important consideration is to buy a filter that is NSF Certified. The NSF is a non-profit organization that looks at any given water filter, examines it, tests it, inspects the manufacturing facility and then Certifies what contaminants that particular filter is able to filter from the water.
This is important because if a filter is not NSF Certified then the manufacturer can say it filters anything and everything, whether it does or not. Basically the NSF Certification is your assurance that the filter you buy really does filter the list of contaminants that it says it filters, and you can go on the nsf.org web site and verifiy it.
The NSF even has rules that do not allow a company to say untrue things about an NSF Certified filter, so you know that any claims they make are true and not just advertising hype. This enables you to compare water filters scientifically, based on data, as with the chart below.
Once you find an NSF Certified filter then you want to make sure that you get one that filters as many contaminants as possible for your money. In other words not all NSF Certifications are the same. Some are certified to remove this but not that, and some are certified to remove that but not this...
WATER FILTER REVIEWS OF AQUASANA, BRITA AND MULTIPURE
BRITA WATER FILTER REVIEW:
For example, BRITA seems to be the most popular filter because they are widely available in stores and they're cheap to purchase. However, the Brita faucet mounted system (F-100) and their pitcher filters do not reduce radon, MTBE or PCB's. (Faucet system also does not reduce mercury.)
Most people who buy the Brita "pitcher" filter don't realize that it only filters out a few of the contaminants commonly found in tap water. It is sadly lacking in its filtration power as well as being one of the more expensive to operate due to having to change the filter every 3 months or so.
Many people don't realize that while the Brita pitcher and on the faucet filters cost less to buy there are a substantial number of contaminants that they do not reduce (see below).The Brita pitchers only reduce Chlorine, Copper, Cadmium, and Mercury (some reduce zinc also). While it is better than nothing it is not in this author's opinion good enough to safeguard the health of your family.
The Brita "on the faucet" FF-100 filter does reduce more contaminants than the pitcher does. However, the volume of water coming out of your faucet is greatly reduced (that is the water comes out slowly from your faucet) and it does not reduce as many contaminants as some other filters I would recommend over them. As mentioned above the Brita FF-100 on the faucet system does not reduce radon, MTBE, PCB's or Mercury, 4 important contaminants of health concern!
AQUASANA WATER FILTER REVIEW:
The Aquasana 4000 and its $114.27 suggested retail price (or thereabouts) price tag is attractive to many buyers for its low price. However, the Aquasana filter does not filter several very important contaminants that may be found in your tap water. If you check closely you will see that the Aquasana 4000, 4600 and 4601 on the faucet water filters do not filter any of the following:
Chlordane - "Liver or nervous system problems; increased risk of cancer"
PCB's - "Skin changes; thymus gland problems; immune deficiencies; reproductive or nervous system difficulties; increased risk of cancer"
Toxaphene - "Kidney, liver, or thyroid problems; increased risk of cancer"
Radon - "drinking water related cancer deaths, primarily due to lung cancer."
(THESE QUOTED DESCRIPTIONS OF HEALTH EFFECTS ABOVE ARE FROM THE
ENVIRONMENTAL PROTECTION AGENCY'S PAGE ON DRINKING WATER CONTAMINANTS)
The Aquasana 4000, 4600 and 4601 and Brita FF-100
ARE NOT NSF CERTIFIED TO REDUCE THE ABOVE 4 NOR THE 15 SUBSTANCES BELOW:
Bisphenol A (BPA) Reduction
"So maybe I should just keep drinking bottled water!?"
Bottled water is sometimes just tap water, sometimes it is filtered but you never know what it is filtered with, whether the filters are changed regularly and properly and also the plastic bottles themselves may leach dangerous chemicals such as BPA or phthalenes into your water! Not to mention how bad those plastic bottles are for our environment!
The same is true for those "water stores" or water vending machines: Some have been found to have bacteria in them. I often wonder "Who changes those filters and what filters are they using? And do they change them as often as they should?" I walked into one of these water stores and asked the owner if their filter was NSF Certified or not. He had no clue what I was even asking! They could be using the cheapest, lousiest filters!
Again: IF it isn't NSF Certified there is no real guarantee that it is filtering what they say.
So what we have concluded so far is:
1) You should buy an NSF Certified filter, one that is independently certified by the NSF (a non-profit organization known world wide for analyzing and certifying water filters) to reduce the most contaminants of health concern.
Of the major 3 brands/models we have reviewed above, the Multipure clearly reduces more than the others.
2) You should not buy a Brita because it is expensive to maintain, water does not flow very fast through it, and it also does not remove as many contaminants as the Multipure water filter system.
3) You shouldn't buy an Aquasana because it does not filter some very important contaminants listed above (chlordane, toxaphene and pcb's) and it reduces less mercury and asbestos than the Multipure does.
4) Neither the on the faucet Brita FF-100 or Brita pitchers nor the Aquasana 4000 series reduce contaminants under the NSF Standard 401 which Multipure is certified for (see list above).
So which one should you buy?
MULTIPURE WATER FILTER REVIEW:
Multipure water filters are NSF Certified to reduce the most contaminants of any filter, including the 3 filters reviewed above.
Multipure filters reduce PCB's and radon unlike the Brita FF-100 and the Aquasana 4000, 4600 & 4601.
Multipure filters reduce 15 substances (listed above) under NSF Standard 401 that the Aquasana and Brita models above do not.
Multipure filters are made in the USA by Multipure which has over 45 years of expertise and is a leader in the field of water filtration.
This allows them to back up their products with a LIFETIME WARRANTY* and a 90 DAY MONEY BACK GUARANTEE!
The Multipure Lifetime Warranty is on the housing so this means you will never have to buy another filter system, ever again!
*All you need do is simply maintain it by changing the filter once per year as instructed
(takes about 10 minutes to change it) and clean the inside of the housing with soap and water.
The Multipure Aquaversa filter has been declared a "BEST BUY" by Consumer Reports magazine 2 years in a row!
Multipure water filters also have an excellent water flow and are not known to leak or break unlike some others.
(That's why they can give you a lifetime guarantee on the housing!)
For these reasons I have made the decision to recommend MULTIPURE water filter systems.
I put this page up on the net because I found it very difficult to sort through the maze of water filters and wanted to help others buy a filter that is NSF Certified and that will give you inexpensive filtered water that filters out over 75 contaminants, for as little as 9 cents a gallon, or about $6/month!
My recommendation is that you go where I bought my filter, after much research into this subject and buy a Multipure filter system.
