Comments:

This filter replaced my 20 year old permanent filter that was worn out. The new filter is better than the old one. It has reduced to dust in our home by at least 50%. We are hoping that colds and sniffles will also be cut in half. Outstanding product.

BOTTOM LINE: Yes, I recommend this product

Appears very high quality

Comments:

The filter arrived sooner than I anticipated and in perfect condition. I have not used the filter as yet since I am still using up the old filter as we are just coming in to the summer season. The filter appears to be high quality with a metal frame and screening.

Best investment we have made!

Comments:

Discount Filter rocks!! I didn't know these even existed, until we found Discount Filter... We were a bit scared, and the first week it smelled hot, but we later realized it was just burning off dust that fell into the furnace from the other filter NOT doing its job! We couldn't be more happy with this filter, and live the idea of being able to clean it as needed without a $10^ cost of the filter each time!!!

BOTTOM LINE: Yes, I recommend this product

Lifetime filter

Comments:

Awesome product and Awesome service. I originally order the wrong size. The return service was very easily executed at no cost. This item is at least one third the cost of having it installed by the company that I use for maintenance. A great discovery
