Air Bear 255649-102 FAQ

What filter replaces the Trion Air Bear 255649-102?

Our 20x25x5 "AB" filters are sized for the Trion Air Bear cabinet — a direct replacement for part 255649-102 used in the Air Bear Supreme 2000 and Right Angle.

How do I install it?

Three steps: slide the old media out of the cabinet, note the airflow arrow on the frame, slide the new one in arrow-pointing the same way, and close the door. No tools. Takes about a minute.

How often should I replace it?

Every 6–12 months. Deep-pleat media holds roughly a year of dust in most homes — change sooner with pets, allergies, or after wildfire smoke. Shipping costs the same on 1, 2 or 3 packs, so most customers stock 2 years at once.
