For some reason, I now have a three-year supply of your filters. I just put my first filter in a month ago and I'm being restocked?
The frequency of change is every three months. Your recommendation. This seems to be a shady business practice and needs to be scrutinized.
I will be sending the second box (6) back.

The filters were generally ok but the pleated filter lining did not reach the edge of the cardboard frame leaving gaps along the side of the filter. Not sure this meets my needs or the quality I was expecting from this company.
