This was really needed, we added this air filter to our furnace and ever since the dust ratio has gone down about 50 percent. It uses an ultraviolet filtration system as well so it should make the air we breathe healthier along with the less dust, but the reality is we ordered it because of all the dusting we were doing.

The only drawback is that when the windows are open and the AC or heat is not on, the dust comes back since the windows are not filtered.
