A Watts reverse osmosis drinking water system is synonymous with superior water filtration. Harnessing the power of advanced RO technology, Watts systems filter out a vast array of contaminants, including VOCs, fluoride, sulfates, pesticides, heavy metals, etc., delivering water that's not only pristine but also fresh and delicious. Investing in an under-sink RO system means prioritizing the health and well-being of your household. In addition, the taste of beverages like tea, coffee, and even plain drinking water is noticeably enhanced. With a Watts RO system, households can enjoy consistent access to clean, refreshing, and high-quality drinking water.

Start by clicking on the photo of your Watts system above. From there, you can add the needed filters to your cart. In some cases, you can save time by ordering all of the needed filters in one "filter kit" (not available for all Watts models). Keep in mind that the RO membrane usually only needs to be replaced every two years, while the sediment and carbon filters are replaced every 6-12 months depending on water usage and water quality. For help installing your replacement filters, select your system above and you'll be taken to a page that includes a PDF of install instructions. General RO filter replacement instructions are available here.

Select your Watts RO unit from the list above. You will be taken to a new page that shows the available membrane and filters for your RO system. Be sure to select the correct membrane size (listed in GPD or gallons per day). If you have any questions, please call our customer support team at 877-377-9876.
