This filter works perfectly in my condo unit, change it every three months, it's a great value and an easy way to keep your environment clean and healthy. I have them on 90-day auto send, and they arrive exactly when I need them.

I bought these filters after learning I was using too high of a MERV rating in my system. Once i put these in, the "sucking" sound disappeared from my return register and I noticed a little bit warmer stream from the outlets. Also, the distribution of heat was improved at the furthest outlets.

These filters do exactly what you would expect and are very durable. We like that they are light enough to not disrupt the air flow to the handler, but sturdy enough to trap dust and debris. An excellent value that is shipped with care and on time.

I have been buying these filters for at least the past 5 or 6 years and found them to be of good quality. I have only one negative comment and it is that they come USPS and I then must drive some 20 miles round trip to pick them up and the box always showed some damage.

Linda M Reid 29 days ago

Very good, mid-range dust filters. They arrived quickly and were packaged very well -- nothing crushed or out of place. Since we forget to buy them at the store, this is how we will go in the future. Good product, good service.

David Stein 23 days ago

We have a permanent filter for our A/C and have washed it a couple of times a year. After 5 years the permanent filter is showing signs of rust. I tried buying another permanent filter but it wouldn’t fit. I tried the cardboard ones and they didn’t work. Then I purchased your filters and they work. The reason why they work is that are 3/4 thick. All previous filters purchased were 1 inch thick. Very pleased.

Michael Meehan 17 days ago

I hate to spend a lot of money on filters since I replace them every three months like they recommend. But I want to use a good quality filter too. I used to buy the 3M filters at Wal-Mart for around $8-9 each. And then I found these. As far as I'm concerned they are the same quality and will do the job. They're rated the same. Why spend double the money for the same filter?

Filters are top quality and equal to or better than those purchased at a local hardware store. Discount filters are less expensive but not less effective. They are made just as good if not better than the more expensive filters. Extremely happy with products provided.

Judy Graham 15 days ago

I order all my AC and refrigerator water filters from Discount Filters. The products have always been of the highest quality and best prices around. Also like supporting a company that shares the same Christian values I do. I won't buy any type of filter from any other retailer than Discount Filters.

Just inserted my first MERV 8 Pleated Filter for use at home. Looking forward to seeing the benefits of this unit and will report back at a later date. Priceing of these filters from Discount filters .com was easy and quick, and a lot less than at Home Depot or Lowes. Would reccommend them for your filter needs. I also use their refrigerator filters.
