When it’s time to change your filters, just screw off the old and screw in the new. It’s that simple. No need to turn off the water with our auto-shut one-way valve heads built into the system.

R.O. Quality Water Without the Hassle

Our 3-stage filtration system with Affinity Filtration Technology removes 99.7% of fluoride. And we don’t stop there—our system removes up to 99.9% of 232+ contaminants while keeping in the beneficial nutrients naturally found in water.

The
R.O Quality Water without the need for a plumber
See Why It's So Good

Unlike typical filter technologies, our breakthrough Affinity Filtration Technology uses 7+ proprietary filtration materials to create multiple stages of filtration that can remove an average of 99.7% 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!

Stage 1:
Stage 2:
Stage 3:
Stage 1:

Water first passes through a woven, stainless steel mesh screen, which keeps larger particles from entering the filter.

Stage 2:

Next, water continues through a loose granulated coconut carbon filtration layer, which removes chlorine, bad tastes, and odors.

Stage 3:

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.

Love it!

Love my inner sink filter system! It was super easy to install and I love the taste of the water, super clean! I was prepared for the reduced water pressure, bur I can barely tell...

Our review is 5 stars

We love the product and the taste of the water is excellent. I'm sure we're are consuming 100% pure filtered water.

Easy and effective

Simple to install, fits under even a small sink, and the water tastes fully clean. Slows the flow a bit, but not at all too slow to quickly fill up whatever needs filtered water.

Fabulous filter

Took my husband about 5 minutes to install the filter. Love knowing my tap water is safe to drink and washing veggies and fruit using pure water is very comforting. No more chlorine smell! Already had the pitcher and now the under the counter filter system. Thank you!
