Purchasing filters is certainly helpful if you struggle to remember the time to replace and the size of the filters. It is so simple to open a closet and grab a filter to replace each time the filter needs replacing. You do not have to remember to pick one up when you go to the store and then figure out if the size that you thought it was was the right size after returning home. Easy!
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.
