Using the latest two-stage water filtration technology, the nutraMetrix PureH2O Countertop Water Filter Replacement Cartridges filter a wider range of contaminants than other filters.

Do I have to pay for a plumber to install the system? Our countertop drinking water filter system is very easy to install, and it only takes a few minutes to do; no plumber is necessary. If you have any questions or need assistance, please contact Product Information at 336-389-6987. How often do I have to replace the cartridges? We recommend replacing the cartridges after six months or 500 gallons. also offers AutoShip every 6 months on the nutraMetrix PureH2O Countertop Water Filter Replacement Cartridges. This ensures you will never forget to change your water filter cartridges and always have nutraMetrix PureH2O water. Is this purified water? No, and actually, purified water is not as healthy as filtered water. Purified water undergoes reverse osmosis or distillation, which strip everything out of your water - not only the contaminants, but also the healthy, natural minerals. Our system uses selective filtration designed to reduce contaminants from the water and leave in the natural healthy minerals like calcium, potassium, and magnesium. How do I recycle the replacement filters? To recycle the nutraMetrix PureH2O filter cartridges, remove the ends of the filters, recycle the plastic parts (which are appropriately numbered) and put the carbon either in your compost pile or garden (carbon is good for plant life), or just throw it out (since the carbon degrades quickly, and is a positive component in a landfill). I'm a renter, so I can't drill or modify the plumbing. Which filter system should I get? The countertop system is perfect for renters because it does not require a new hole in the counter. To install an under counter system, you can remove the existing sprayer or soap dispenser in your rental and install our faucet in its place. This option will not damage or permanently modify your plumbing. When you move out, you can easily remove the system and reconnect your plumbing back to normal. What size adapters do you send with the countertop system (for the diverter hose)? 13/16 and 15/16 male. What size is the chrome collar on the countertop system (on the diverter hose)? 55/64-27 female. What does TDS stand for, and what is TDS? Total Dissolved Solids: dissolved minerals and metals. TDS meters tell you the concentration of dissolved minerals and metals in your water, but are not an accurate measurement for contamination. The nutraMetrix PureH2O Countertop Water Filter reduces harmful TDS, like dissolved lead and iron, but since our selective filtration leaves in calcium, magnesium and potassium, and minerals are dissolved solids, there will still be a measurable amount of TDS in our filtered water. What is BPA? And why are people concerned about it? BPA stands for Bisphenol-A, a contaminant found in most plastics. BPA can adversely affect your health if consumed at high levels. nutraMetrix PureH2O Countertop Water Filter does not contain BPA, and our filtration process reduces existing BPA. Does having hard water mean it is contaminated? Hard water is more of a nuisance than a health risk, and is not necessarily contaminated. Most water sources in the USA are considered hard. Hard water is generally safe to drink, after it has been properly treated. What is soft water, and is it safe to drink? Having soft water just means you have a lower concentration of dissolved minerals in the water (primarily calcium and magnesium). Soft water does not mean clean water. Your water can be soft and still contain contaminants. What is selective filtration and how does the nutraMetrix PureH2O Countertop Water Filter System filter drinking water? Selective filtration is the process of sub-micron filtration, micron filtration, adsorption and ion exchange, all of which selectively reduces chemicals, heavy particulates and most dangerous heavy metals from the water while maintaining healthy minerals like calcium, magnesium and potassium. How do I know if the nutraMetrix PureH2O Countertop Water Filter will be compatible with my faucet? The nutraMetrix PureH2O Countertop Water Filter will not be compatible with are the 2-in-1 faucets that have a detachable sprayer at the faucet opening. It will fit most standard faucets and also comes with two adapters.

Great Product!

We have well water and was tired of the changing taste. I bought this and the under sink attachment. My husband and I did 3 rounds of blind taste tests with each other and you can clearly taste the difference! It is so nice to have safe, clean, and yummy tasting water for my family! Both children have the filtered water bottle for school as well. :)


Great for newly chlorinated well water.

We have a well and our pump died. When it was fixed they chlorinated the water and it was gross! It took over a month of regular water use after wasting who knows how many gallons flushing the system for the chlorination to go away. The only savior was this Pure H20 water filter. It allowed us to have wonderful drinking water for us and our dogs. It removed all of the chlorine smell and taste from the water and saved us hundreds of dollars in bottled water as well as the recycle center from all the empties. I took my filter for granted before this episode, now I so much appreciate it!
