How to Find & Order RO Replacement Filters: So it's time to replace the filters for your Reverse Osmosis water filtration system. Figuring out which filter or membrane you need to purchase can be overwhelming.

Get started by determining the brand of model of your RO filter system.

Tips to Determine Brand and Model of RO System

The most accurate way to get the right replacement RO filters is to identify the brand and model number of your current system.

Identify Your RO System

  1. Identification information is usually found on the metal or plastic manifold that holds the filters in place
  2. The model number may also be located on the back side of the manifold on a small sticker
  3. Generally, labels on individual filters do NOT indicate the RO system brand or model

If there is no label on the RO system or you are unable to identify the brand and model, then use this guide to identify and select the system image and description that most closely matches your current RO system

The RO membrane only needs to be replaced every 2-3 years. The other filters are typically replaced every 6-12 months. You may be able to purchase a replacement kit bundle which will provide all the filters for your system.
