9827DC-6 Micro Allergen Airflow System Filter

I was using Filtrette Clean Living filters for years and was happy with its performance. Having read about the higher filtration levels of Allergen Defense, I decided to order this one for my 20X25X1 opening of my AC unit. To my surprise I was not able to fit it into the hole into which the Clean Living filter entered easily. The Allergen Defense is taller than Clean Living filter of the same posted sizes 20X25X1. Please advise what could be done. Thanks!

I have been using the Basic filters my husband provided for our furnace. I went to get some more filters three months ago and discovered the above-noted filters. Since I have asthma, I tried these. The 1085D filters work great! They cleaned so much more gunk out of the air. I definitely recommend these. Thank you.

I will not buy any other filter except Filtrete. Traps more dust and allergens than one could imagine. Two of our children have allergies and they really noticed improvements since we started using Filtrete [This review was collected as part of a promotion.]

I have always used Filtrete™ Allergen Defense Air Filters. They help to minimize the effects of allergies. I can breathe so much better with this product. Keep up the great work so I can continue to breathe easier. Great products!! :) [This review was collected as part of a promotion.]

Although I like & have to have this filter for my house HVAC system, I find that I am changing the filter every month NOT the 3 mos it is supposed to last. I did let one set go approx 45 days, but found the old filters collapsed into the vent due to the lack of air able to pass through. They do clean the air that passes thru, but definitely NOT for 3 months! I would seriously consider another filter if available, at least to have comparison...more to follow if I do find one/some.
