Need filters that standup
We have used filters purchased from AirFilters.com for the past 10 years. During that time we have never experienced any issues with their filters. We have always found these filters to be free of any defect and the quality is outstanding. We always buy 3 to 4 filters at a time and because of the quality we only change them every 6 months.
We would highly recommend AirFilters.com.
