ICS-SP0621K Cartridge Filter Replacement Kit
The ICS-SP0621K Cartridge Filter Replacement Kit is specifically designed to perfectly fit the Nuvo H2O Studio housing without modification. It is engineered as an upgrade to the Nuvo H2O Studio series. It is both a sediment filter and salt free water softener and lasts twice as long while treating more problems and producing better water.
- First treatment is a sediment filter to remove particles, protect and clarify
- Second treatment is PolyHalt® salt free softener and water conditioner




Small Size Means Flexible Install
Don't sacrifice precious garage space. The whole house filters from Cascadian are much smaller, and take up no floor space.

FAQs
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.
