Purchased a 3 pack of dirt devil dust shield A/C filters made by american air filter company out of Louisville Ky. Put the first one in and as soon as the A/C unit came on, it folded into a “V””. Put a second filter in
same thing happened. On the filter is stamped 20x25x1. In small numbers on the filter is stamped 13/16″”. The filter measures about 11/16
less then 3/4’s of an inch thick. Talk about a rip. A waste of time and money. nCorynSan Antonio
