3-Stage Under the Sink Replacement Filters



Unlike typical filter technologies, our breakthrough Affinity Filtration Technology uses 7+ proprietary filtration materials to create multiple stages of filtration that can remove up to 99.9% of 232+ contaminants. This means no need for a plumber, simple easy-twist filter replacement, contaminant removal levels beyond reverse osmosis and no permanent installation. It's a no-brainer!



Water first passes through a woven, stainless steel mesh screen, which keeps larger particles from entering the filter. Built in the USA.
Next, water continues through a loose granulated coconut carbon filtration layer, which removes chlorine, bad tastes, and odors. Built in the USA.
Water then flows through the filter’s composite shell, which is made of 7+ proprietary filtration materials. This dense layer slows down the flow of water and allows for the filter to have more time in contact with the water. The combination of the proprietary breakthrough technology and additional contact time allows for superior removal percentages on all contaminant types. Built in the USA.

All three filters must be changed at the same time. All municipal water supplies are different, so the frequency at which filters need to be changed is always approximate. We recommend making a note of your installation date as a reminder of when to replace the filters or you can sign up for our filter subscription: you’ll never forget to switch your filters and you’ll save 10% on each filter replacement!
*If your tap water is heavily contaminated (most likely if you live in a large or older city), your filter must work harder to keep your water clean, which will decrease the life of the filter.
- Fluoride: removed at a rate of 90.7%. It is difficult to remove once it’s added into the tap water and typical carbon-block style filters don’t have fluoride removal capabilities. For that reason we specially formulated our technology so fluoride removal is standard with every filter.
- Glyphosate: The active ingredient in Roundup® weed killer. Our filters remove >99.9% of this highly controversial chemical.
- PFOA/PFAS/PFOS: The chemicals that make pans and apparel “non-stick” but are extremely toxic when consumed. Removed at a rate of >99.8%.
- Lead: Even though it’s been widely banned due to its highly poisonous nature, lead pipes remain in use across all 50 states. Lead is harmful to human health even at low exposure levels and accumulates in the body over time. Removed at a rate of 98.9%.
- Chlorine: While chlorine is effective at reducing the spread of infectious waterborne diseases, it reacts with naturally-occurring materials in water to form dangerous chemical byproducts that threaten your health. Removed at a rate of >98.6%.
