Review on Quality 18X20X1 Pleated Furnace Filters by FilterBuy - Efficient and Durable by Mike Davis

Filter size I need my new air conditioner unit is rare (18x20x1) and not usually sold in hardware or grocery stores. This means that I will be ordering them online in the foreseeable future. These filters arrived in perfect condition, not bent at all. The one I currently have in my air conditioner has worked very well and seems to be doing its job of keeping dust and dirt out of the air. I couldn't ask for more. The price was also quite reasonable, especially in the range I'm used to spending on filters that are used for several months at a time.
