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.

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.

Good filters made to order My A/C takes an odd size filter (29 1/2 x 23 1/2) and I can't find a high quality filter in the store. This is my second order with them and these custom made filters are a perfect fit and last 2-3 months. The only issue I had is a delay in knowing how long from ordering before shopping and they were slow to respond to my status update request (their email response came two days after I received the filters and it didn't even indicate shipment was made.) Otherwise, everything was perfect.

They don't want my business They don't want my business. I tried repeatedly to create an account but they require entering a Captcha, which doesn't work. I even tried with different browsers and different computers! They have no customer service phone number, and are accessible only via chat. Their chat rep had no answers and was entirely non responsive. I encourage readers to stay away from this customer "no-service"

My AC unit takes an off size filter… My AC unit takes an off size filter that can not be found in any store , this is my third order of filters from them and happy with the company . Do not wait till last minute to order as shipping time is roughly a week but again my filters are custom size so they make them .
