I have replaced Aprilaire filters in the past and it was one giant pain! This installation was very easy once I figured out just how to fit it in the frame. I will be buying another one in the future.
We had a real interesting smell in the house and we were considering doing a ventilation system flush. Those are expensive. A friend of mine is an AC Tech and asked the last time I changed my filters. I cringed cause I literally had no idea. I replaced the space gard filter and added a carbon filter at the advice of an engineer friend and viola funky shell is no more. Thanks filter buy!
