Trion's Corporate History

Trion Filters are manufactured by Trion Air Purification Systems. Trion started manufacturing air purification systems in 1946 in Sanford, North Carolina. Trion has gone through a number of mergers and acquisitions, including the 1996 purchase of Herrmidifer, a well-known manufacturer of humidification products.

Today, Trion is a subsidiary of Fedders Corporation (NYSE: FJC), a manufacturer and marketer of air conditioners, air cleaners, dehumidifiers, humidifiers, and thermal technology products.


Trion filters are designed to work with the Trion Air Bear whole-house media air cleaners. Trion is made of a 100% electrostatically charged synthetic material with surface pleats that has a large dirt-holding capacity, even when compared to other filters. Trion filters remove dust, smoke, and airborne particles from the air.

Another popular filter is the Trion Charcoal filter. Trion claims these filters never need replacement.

Trion replacement filters are available in several sizes, depending on the air cleaner system. The most popular filter is the Air Bear filter and the Trion Air Bear Cub filter system. These filters only require replacement every six to 12 months, depending on the type of filter. Trion also manufacturers a charcoal filter for use with air cleaning units.

Many companies create reproductions of the Air Bear filter. Check to make sure the product states "Genuine" Trion filters, or says OEM (Original Equipment Manufacturer), or it may be a reproduction filter.

Where to buy Trion Furnace Filters

You can buy Air Bear air filters from several online vendors and from heating and air conditioning installation companies. These filters have a retail price starting at $77.00 for a 3-pack. The Trion Charcoal filters retail for $29.95.


Air Bear filters are intended to be used for six months. Some of the models are meant to be replaced after 12 months. The filters do not carry a warranty.
