INSTALLATION & USE
Installing Your Nitrate Filter
- Shut off water supply and depressurize the filter housing before opening
- Remove the Aries AF-20-3610 from packaging and insert into a compatible 20"x2.5" standard housing, ensuring proper seating
- Hand-tighten housing sump, turn on water supply slowly, and check for leaks
- Flush filter for 5 minutes before use to rinse resin fines and prepare media
- Monitor nitrate levels periodically and replace filter when reduction performance declines
COMPATIBILITY
Works With Standard 20" Housings
The Aries AF-20-3610 fits any standard 20-inch filter housing designed for 2.5-inch diameter cartridges. Commonly used in whole house filtration systems and point-of-entry well water treatment applications. Best results are achieved when installed after sediment pre-filtration to protect the resin bed from particulate fouling. This specialty filter is ideal for well water with elevated nitrate levels or municipal supplies in agricultural regions.
🔧 Pro Tip: Install a sediment pre-filter upstream of the AF-20-3610 to extend resin life and maintain optimal nitrate removal performance. Test your water nitrate levels before installation and every 3-6 months to determine replacement timing based on your specific water chemistry.
