A little bit expensive for basic filters with minimal rigidity /strength? Due to the suction force of our system, I had to reinforce these filters with pieces of wood? for replacements in the future - i will need to get metal frame ones? for now I'll make due.
Being able to buy filters by sizes not available through local home improvement outlets is wonderful. Heat and air manufacturer's make units with filter sizes that vary by unit sizes, thus making filter replacement a challenge at the least. This company narrows that playing field down, because you can get filters in a variety of sizes to meet your individual needs. Marvelous!!
