The filters are just OK but not very robust. Very difficult to load into the Aprilaire filter holder and do not make a good seal. I thought it would be easier and better than the combs and material. Ill use these two and go back to the regular ones. Shipping was fast
I'm so happy I found FilterBuy. I signed up for annual shipments and now I don't have to worry about having to run to the store to buy filters. I even got 6 filters for the year for far less than I would going to my local store!
So far we love the new filters. My husband has lung disease and since putting in the filters he swears he is breathing better. I will continue to use your filters.
