What filter replaces the Trion Air Bear 229990-102?

Our 16x25x5 "AB" filters are sized for the Trion Air Bear Cub cabinet — a direct replacement for part 229990-102.

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.
