They do a good job of trap in the dirt and pulling a lot of junk out of the air.

We have a heat pump, oil fired furnace, and air conditioner in one unit. All our ventilation goes through that system excluding when the windows are open on certain nice days. We have 4 cats and these filters do a great job of removing dander and many other airborne particles.
