"I was very impressed with the filter. It was more substantial than OEM Lennox filter I replaced. It was also less expensive than the Lennox filter. Extremely happy with the filter."

"Very easy web site to navigate. Great prices. Super quick shipping. Just an all around great shopping experience!!"

"These are high quality washable filters and they fit perfectly. I don't understand why one would pay more for the competitors when these filters are above average in filtration and stability."

"This is the 3rd time I have ordered from your website. Easy process great filters and quick delivery. Thank you for the service. I have promoted your website to many of my friends. "

"My order of 6 furnace filters were shipped in a couple of days. I received the box 2 days later. I will continue to shop online at Factory Direct Filters."

"Product appeared to be high quality at a much lower price than the box stores (when I could find my size). I ordered a dozen 18x24x1 of their premium filters and they arrived a couple of days later in two boxes. Will definitely order from them again next year."

"Quick, easy and very fast delivery! I will be using this company again!"

"I have used your filters before and never had any issues. On 2-2-16, I ordered 20 x30 x 1 Merv 13 Pleated Air Filter x 12. When the case was delivered it had a crushed corner and 3 corners of my filters were damaged. I notified the company and problem was resolved instantly. I was sent 6 more filters at no charge.

That is fantastic customer service.

"I ordered them on Monday and they were delivered by Wednesday. Great Service."

"Super easy. Mailed to me. Great prices!"
