Poor quality - Don't back their products Poor quality I purchased 6 air filters and when I removed the first one from the blower unit, I noticed that the pleats had separated from the frame allowing air past the filter. I noticed one other filter (not used) where the pleats had also separated. I contacted air filters delivered and they said there was nothing they could do about the problem since the order was 2 months old and would not replace the filters.

I question the MERV ratings on this… I question the MERV ratings on this site. No where on the filter does it state in printed format, what the rating is, yet smacked on the side of the filter is a stamp that says MERV "XX". I don't know enough about filters to know if this is the correct filter but something is certainly fishy with these filters. The filter is constructed poorly with pleats pushed together and I don't see the quality I've seen from other well known brands such as 3M etc. I'm ordering some other lesser MERV filters to compare and will report back.

Very convenient for hard to find sizes. Air Filters Delivered is great for finding hard to find air filter sizes. The site is easy to use. The pricing chart for the different grades of filters is the best thing about the site. It makes ordering exactly what I want very simple. Air Filters Delivered's prices are competitive with other air filter sites with discounts for larger orders and free shipping.

Poor quality air filters The outside 'frame' of these filers is flimsy paper, just heavy enough to be called cardboard. The filters were immediately sucked partially up into the duct, making them useless. I am going to build/attach some metal brackets to make the filters more rigid so they aren't a complete waste of money. Will not be purchasing again.

Great product and fast delivery Their air filters are a perfect fit for our a/c. It's impossible to find our size locally. I've been getting our air filters from Air Filters Delivered for several years. Very happy with the product, and considering they are custom-made filters, they deliver fast. Thanks!
