ERO 300 3-Stage RO Compatible Replacement Filters
This is a three stage reverse osmosis system. The carbon block pre-filter removes chlorine and small particulates so the RO membrane is not damaged. The carbon block post-filter adds a finishing touch for taste and odor. Find compatible filters below.
Due to a discontinued membrane, we recommend switching to the PureValue 5EZ50-RK RO Retrofit Kit for continued use if your tubing is 1/4" in size. This allows for continued use the tank and faucet and for an upgraded membrane to be used for updates in filtration technology. Please check your system as a different retrofit kit may be required.

Helpful Filter Information
Not all filters have the same replacement schedule. Replace the RO membrane filter every two years. Replace all other filters every 6-12 months. Help keep your system sanitary by never using filters longer than 12 months, except the RO membrane filter, regardless of how much water you use.
