AprilAire 35 Replacement Water Panel Humidifier FilterThe Genuine Trion Air Bear 259112-102 20x25x5 MERV 11 Furnace & AC Air Filter is a whole house HVAC air filter designed to improve indoor air quality by capturing up to 90% of airborne particles between 3–10 microns.

- Helps reduce allergy and sinus irritation symptoms by removing common airborne irritants such as dust, pollen, mold spores, and more.
- 6–12 months lifespan means less frequent maintenance compared to standard 1-inch filters.
- Energy-efficient design helps heating and cooling systems operate more effectively, potentially extending HVAC equipment life.
- Made without fiberglass, offering a cleaner and more durable filtration material compared to some alternatives.

Frequently Asked Questions:
How do you install the Trion Air Bear 259112-102?
- Open access door by lifting the handle and pulling the bottom of the door toward you. Remove door completely.
- Tilt used 259112-102 filter cartridge to allow filter to be removed from cabinet. Pull used filter cartridge from cabinet.
- Discard dirty 259112-102 filter cartridge in plastic bag in which replacement filter was received.
- Slide new 259112-102 filter cartridge into cabinet with “AIR FLOW” arrow pointing in the direction of air flow. Care shall be exercised to place filter cartridge in angle holders on bottom and side of cabinet.
- Replace access door.
How often should you replace the Trion Air Bear 259112-102?
Changing your Trion Air Bear 259112-102 is a very quick and easy process that should be done once every six to twelve months.
What contaminants does the Trion Air Bear 259112-102 reduce?
The Trion Air Bear 259112-102 is a MERV 11 air filter, which means that it reduces the following contaminants:
- Dust
- Pollen
- Mold Spores
- Pet Dander
- Smoke & Smog
- Other Airborne Allergens
Does it matter which way the filter faces during installation?
Yes! There is a printed Airflow Arrow on the edge of the filter frame. This arrow must point toward the furnace or air handler (the direction the air is moving). Installing it backward can cause the pleats to collapse or reduce the filter's overall efficiency.
Why is my new filter slightly smaller than the cabinet?
The Trion Air Bear 259112-102 is designed with a small amount of space to allow for easy sliding into the tracks of the air cleaner. The gasket or the tight fit of the cabinet door is intended to create the seal. If there is a gap larger than 1/8", ensure you are using the correct "Actual Size" filter.
What is the MERV rating, and what does it filter?
The Trion Air Bear 259112-102 is a MERV 11 filter designed to capture 90% of particles between 3.0 and 10.0 microns, including mold, spores, pollen, and other airborne contaminants.
