Filtrete 20x30x1 Air Filter MPR 1200D MERV 11, Allergen Reduction Plus Dust, 4-Pack Filters exact dimensions 19.81x29.81x0.81

[This review was collected as part of a promotion.] We live in an apt with forced air heating. That creates a lot of dust in itself. Alll of us have allergies to something different. My son is spring trees, I am dust and my husband is all year round. We buy our own rather than use the ones the complex does. Plus, they hardly change the filters on a regular basis. I am careful as to which filter I can use for the HVAC we have. Don't want to block too much air and ruin an expensive machine. For 30 years I've used these filters without a hitch. When we got new carpeting (such as it is called) it was the thinnest cheapest I've ever seen. Carpet is supposed to shed, this one just creates dust. Thanks to the filter I had less dusting to do.

[This review was collected as part of a promotion.] I've tried other brands, but in my opinion nobody makes a better filter than Filtrete! It is unbelievable how much dust these filters intercept in my house!
