Odd Size A/c Filter?
Is anyone aware of an online supplier of air conditioner filters (preferably pleated) in the size 22" x 30" x 1". I've Googled for a/c filters and all the suppliers I checked had just about every size but this one. A local store will order them but will sell them only by the case of 12. (Perhaps online suppliers would insist on the same??) I am a minimal a/c user, so a filter lasts longer than the standard 90 days. Storing a case of filters of this size would be a pain.
Answer:
I took another tack. The size is fine for me, but I got tired of stocking, buying, etc. I went to the local HVAC company here. Gave them an old filter, and said to make me a washable one -- they bent up a nice galvanized frame with "rubberized horse hair," or whatever it is they use in the washable filters. $12 + time to drive 3 miles. I simply pull it out once a month and hose it down with the hand hose in the shower. I spray water soluable filter oil on it to help it pick up the dirt. Same stuff I used to use in electronics equipment filters in another life. Here's what I ended up doing, in case anyone is interested. 20" x 30" x 1" pleated filters are readily available. I bought one of these. I lined the intake opening with 1-1/2" wide strips of cardboard by caulking the strips to the walls of the opening. (The opening is blocked by medium-mesh chicken wire, so nothing gets sucked in.) I also attached small 1" wide pieces of molding along the two long sides to keep the 20" sides of the filter centered. So far, so good. I'm assuming the relatively small reduction in area will not affect the system.
