Trion 259112-102 3pk
FiltersFast FFC20255TAB

The Trion 259112-102 replacement filter media is made of an electrostatically-charged synthetic material that effectively traps particulates such as dust, pet dander, spores, mold and pollen so that air can pass through the filter media with minimal pressure drops. This simply means that the Trion 259112-102 beats the competition, as many air filters are less effective months after installation. Trion recommends replacing this item every 6 to 12 months for optimal performance and efficiency.

Filters Fast has an excellent selection of filters. Especially when finding a fair price. As I have an HVAC unit and filter media that is quickly coming up on 29 years old. Finding optional brands to do what the original (brand name) would do. In addition, often able to move up in MERV value. In my case, one MERV up from the original (MERV 10) to 11. Makes the difference in what removes pet dander and cigarette smoke. Although I no longer have pets and do not smoke. Just means it's all the more cleaner. And 1 MERV does not require a speed change of the squirrel cage fan.

Arrived super fast after order was placed however had to wait for a month for them to be restocked. Could not simply place the order ahead of time and have them send when they restocked. Had to wait to place the order until the stock was in place. Price was fair but not necessarily a deal.

Love Filters Fast. They make it easy to get what I want and ship it quickly. Love the 3 Pack Trion Air Bear Supreme 200 Filters 20x25x5. No complaints, you could run a sale every now and then. -)

Ordered delivered and installed.

The filter fit perfectly in my new house's unit, so I think I'm good to go. Read mostly positive reviews on these filters before buying, and this website appears to have the best deals on them. Quick shipping, got the product with no damage. Couldn't be happier with the service and product.
