Filter adjustment

Oops. I bought the wrong size filter for our house air filters. I’m going to chalk it up to distraction in the store because I had the correct dimensions on my list. I did not want to go back to the store. Luckily, they were oversized and I could cut them down.

Mark the filter to the correct size minus 1/8” and use kitchen shears to cut off the whole end
Kitchen shears also work well to run underneath the cardboard edges and release them from the glue
Tape the cardboard end from the cutoff piece onto the main piece. Use a marker to change the printed size so you don’t make the mistake again.
Install the fixed filter! Do remember to mark the date of change and dust the cover.
