Where does the ICS system 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

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

Way to expensive

$100 is overpriced for a small water filter. The fact that it can only ordered from the company is also wrong. There is no pricing competition.

Hi Susan,Thank you for your feedback. We understand your concerns about price and availability. While it features advanced technology for optimal performance, we acknowledge individual needs vary. We'd love to discuss alternatives that might better suit you, please contact our customer service team.

Installed as a whole house filter to reduce hard water. Reduced hard water from 400 parts per million to 300 parts per million. Wanted to upgrade to larger filter housing but I'm only the renter.

Good filters. But very expensive.
