How To Trim Your Return Air Filter in a 8 Easy Steps.
This quick project took hardly anytime at all and really makes an eyesore much more attractive. With only a few tools and materials this took a few hours from start to finish.
With so many scrap pieces of Drip Cap molding laying around after the ceiling project, door and window trim I decided to keep it cohesive and use it to trim out our return air filter. I purchased these from a local overstock warehouse for $2.00/stick.
Step 1 Measure and mark trim:
I marked the trim on each end where my outside angle cut will start, also adding a cheat mark as a reminder which way the angle will go.
Repeat for all for sides of return air filter.
Step 2: Cut trim using a miter saw.
Repeat for all four trim boards.
Step 3: Paint
I paint my trim before attaching to the wall to avoid getting bright white oil based paint on my blue wall. You can add this step to the end of the project if you use water based paint for your trim.
Step 4: Clean and change filter
Might as well clean and change your air filter if you are going to the trouble to give a facelift! Using rubbing alcohol and a small dollar store scrub brush, I got all of the caked on sawdust off of this grate really fast.
Step 5: Attach trim to the wall
Using an 18 gauge pneumatic nail gun and 2″ finishing nails, I attach all four pieces of trim to the wall.
Step 6: Fill nail holes with your favorite wood filler.
18 gauge finishing nails hardly leave a hole at all, so this step goes by very quick.
Step 7: Caulk
There were very few gaps between the trim and the wall but I caulk everything, possibly overkill…
Step 8: Touch up surrounding paint

I shared this project as a video on my YouTube channel. Since I only took video of the project that is the reason I am in every picture :-) Recently I learned how to save parts of my videos as a picture or .jpg So I went back through the video so that I could share this project with my blog friends. Hope you enjoy it!
