Identify My RO System
The most accurate way to get the right filters for your RO system is to identify the brand and model number.
• Identification information is typically found on the metal or plastic manifold that holds the filter housings in place.
• The model number may be located on the back side of the manifold on a small sticker.
• Typically labels on individual filters do NOT indicate the RO system brand or model.

Order Reverse Osmosis Replacement Filters
Once you've determined the brand and model, follow the filter and membrane replacement schedule for your system to ensure your Reverse Osmosis system functions properly.
Most drinking water filters should be replaced every 6-12 months. But Reverse Osmosis membrane only needs to be replaced every 2 years. The time length can vary based on water contaminants and water usage.
To simplify the filter replacing process, we offer replacement kits that bundle everything needed for the annual filter replacement. Start by selecting your brand on this page and then follow the link to your system model to see if a replacement bundle is available.
How to Install Reverse Osmosis Filters
When the filters arrive, follow the instructions on how to change the RO filters and membrane. Note that when changing RO filters, it is strongly recommended that you sanitize and clean your RO system at the same time.
We also provide step-by-step instructions for replacing reverse osmosis filters yourself.
