Clean, Convenient, Safe

Our 3-stage filter system is as simple as it gets.
If you want the water coming out of your kitchen faucet to be pre-filtered, then this is your answer. We designed a three stage under sink filter system that will deliver clean & safe water right from the convenience of your tap. It has stainless steel hoses with the fittings already put on for you so the installation cannot get any simpler. In fact, the entire system installs in less than 5 minutes! Our record is 2 minutes, 2 seconds using nothing but a wrench and a screwdriver. (Click here to Watch Our Installation Video)

Most Frequently asked questions:

How long will the filters last?
On average, the filters will last 12 months (1 year).

How hard is it to change the filters?
This is the best part, we fitted each filter with it’s own automatic shut-off valve. So there is zero chance of a leak, even if you forget to turn off the water knob while you are changing filters. They are a simple twist-on/twist-off design so there are no special tools required to change out your filters, you just use your hands. Here's our How-To Video which shows the process: How to Change Out Under Sink Filters

Do I need to install a separate faucet for this?
No! This system installs directly on the cold water line already going to your kitchen faucet. So everything that comes out of your cold water line is filtered and ready to go.

Will it affect my water flow?
Yes, typically we see about a 20-25% reduction in water pressure on the cold water only. Note: this does not filter the hot water coming out of your faucet, so the filters will not be in use when washing dishes or cleaning. The reason for slowing down the flow is the filter simply needs contact time with the water in order to remove all the different kinds of contaminants. We could make it flow faster, but then it wouldn’t be able to remove everything.

How does it compare to a Reverse Osmosis System?
So glad you asked! We recently wrote a blog and made a video answering just that! Check it out by clicking HERE

What if I am renting Or plan to move at some point?
This is the PERFECT solution for people who are renting or may move at some point. Our under sink system is not a permanent install. It can be removed as easily as it is put in, and only takes about 5 minutes. That means you can take it with you if you ever decide to move. There is no drilling into your countertop required or modification to your sink like with typical Reverse Osmosis products.

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.

Kerry Cancienne

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!

The best!

Extremely easy to install and replace! And the company is extremely friendly and responsive in case you have questions. It goes without saying that the quality of water that the filters yield is top notch. 100% recommend it.

Under the sink filter system

The installation was a zip and I noticed the taste of water is greatly improved. It is so much more convenient to receive tasty water through the tap.
