This Health filter is made of great quality and performs well trapping dust and particles if you change it every 3 months,you will see a difference in your air quality.I have been buying them for a while the shipping is quick through discount filters.

I have been shopping Discount Filters for 15+ years. They make choosing, ordering and follow up easy peasy. Their filters have always been economically priced and of high quality. I buy these filters annually. Enough for each of our hvac maintenance visits. I will always recommend them to my family and friends when I know they have filter needs.
