The filter is excellent. The size was hard to find locally. The price from Discount Filters was excellent and the filters were received very quickly, in perfect condition.

Competitive pricing and delivered as promised. I liked the fact that they had options as to how many you buy. Other stores only offer singles or 5 packs, etc. I only wanted to pay for 2 at this time.

Graham Fizer 6 days ago

Great product at a great price. Paid less for two filters than what I would have paid for one at other retailers. My only complaint is the snail pace that FedEx shipping operates with, but I know that’s out of your control. I’ll be telling people about this site.

Roxanne Torres 7 days ago

This product didn't have as many pleats as the TopTech I received from my Air-conditioning company & it fit a little snug. This is my 1st time buying, I'll watch my A/c & see how things go.

Mary Bond 27 days ago

The product is fine - the packaging for shipping, not so much. I ordered 4 of these, and they arrived in 2 different boxes- one sized just right for 2, and one way to large for the other two, without any packing inside to keep them from tossing around. The two in the small box arrived in great shape, the two in the large box were dented and bent, but still of use with some effort to re-straighten them. They ought to have been packed better, considering their cost.

Seems to be working well. Noise is gone..will replace in 6 months. Thank you for your discount also

Thomas Spindler 29 days ago

It appears to be well made and at a lower cost. My concern is that it does not have as much filtration area as the original "Top Tech". I calculate 800 sq. in. , and your replacement filter calculates to about 600 sq. in. Additionally, I have purchased filters from Discount Filters before, and plan to do so in the future due to economics and terrific customer service.

Mary Lou Stephen 8 days ago
