Furnace Air Filters

They are a good quality. I always get the two pk %26 I always date them when I change out so I can see how long between change %26 the difference in collection. These I can go 6 weeks as opposed to a month with others. If I want to dust %26 sneeze a lot I can squeeze a month but not worth the allergy irritation.
