I was so pleased with the whole house filter!! Best item I have ordered within the last year. The stainless steel housing is too pretty to hide under the house. My wife was worried I was going to hang it in the living room! But I am using it to filter well water that also feeds the sprinkler system. I fill my swimming pool from this source. It had a high sulfur content, so I was really putting the filter up against a tough test. But the water is so clean now, I actually tasted it! This will reduce the burden on the pool filter. Since the unit is outside, I do have to ensure I have winterized it to avoid damage from freezing. And when I installed it, I found it very simple. However, I have done my own PVC piping for years, so I do not want to make it sound like a slam dunk!
As you can tell, I am very, very happy with this product, and will probably purchase a second one for the whole house filtering. My ONLY concern is I cannot find where to order the filter elements. I would like to have at least one set in reserve, and more than that when I get the second unit.


I am very pleased with the whole house filter works as well as the $3000 dollar set up in my previous home. I will certainly recommend your product to those I meet...thank you...

Easy install

Cleaner water then without the system.

Love it

We will definitely be ordering more of these! The addition of the gauges is awesome.

First Impressions

Just finished installing the whole house filter. Ordered during the pandemic and took a long time to arrive, knew that in advance. Very sturdy stainless or chrome plated nice. I used 1” pipe and have increased pressure now (80psi from city and 65psi out of regulator), I had 3/8” for whole house before. I was worried about over tightening the plastic connections and now they leak, will use paste instead of teflon next. I had some random smells and haven’t noticed any since so thumbs up. One of the gauges doesn’t read past 8 psi but haven’t spoke to customer service yet. They are really nice oil filled gauges. No leaks from factory fittings or filter seals. You will need some accessible space to install, working great in my 100+ year craftsman so far. Hopefully I can do another review in 6 months or filter change.
