Can I use Ultra Sterasyl and Ultra Fluoride filters together?


It's not necessarily a good idea to use two different cartridges. The two cartridges do not filter the same things. For example, water passing through the Ultra Sterasyl filter will always contain fluoride (if your water contains fluoride) and water passing through the Ultra Fluoride filter will always contain PFAS (if your water contains PFAS).

In order to make the right choice between Ultra Sterasyl and Ultra Fluoride cartridges, you can check water quality by requesting analyses from your water supplier.
