We have allergies. If we start sneezing, it usually means I forgot to change the filter!!! Our filter seems to work very well at capturing pollen, dust, etc.

Oh, this company has great products. Even better storage service. I made a mistake and ordered the wrong size. They asked me a couple questions. And then replaced the filters with the correct size. Told me to donate the other ones and gave me the price difference. As a refund. I will be buying my filters from them from now on.

I am never without Quality Filters

My filters are replaced once every three months. I buy 4 at a time. I get a new set every year just before I pull the last filter from the furnace. It is practically automated.
