Small Size Means Flexible Install

Where does ICS go in my Home?

Where it can fit, and where it can easily get access to your home's water source. This is typically a garage, crawlspace, or even a closet. If you have questions a plumber would be able to help you find the best spot. During maintenance you'll need to fit a bucket and have enough space to turn the sump wrench which comes with your system.

How often do I replace the filters?

Most people replace their filters once per year, or sooner if they start seeing issues with their water again. Learn about water issues here

What is the return policy?

If you are unsatisfied within 60 days of purchase, return the housing and we'll refund your purchase no questions asked.

How fast do you ship?

We typically ship same business day if the order is placed before 2 pm PST using UPS ground.

It's important to note that products featuring PolyHalt® - identifiable by a 'P' in the part number - may be damaged by contaminants such as hydrogen sulfide or tannins. To ensure optimal performance of PolyHalt®, these contaminants must be adequately removed from the water.

Our ICS-H product offers a suitable option for pretreatment for hydrogen sulfide. Utilizing ICS-H will aid in eliminating these harmful substances, thereby preserving the efficiency and extending the lifespan of your PolyHalt® products. Always remember to pre-treat your water with ICS-H when necessary to ensure the best performance and durability of your PolyHalt® system.

Rating water filter

We do not think it does what we were lead to believe. We still have hard water film on our shower walls and base.

Hi Diane, This is very unusual and not the experience most customers have. Please contact us for assistance with your treatment system.
