A/C Return Air Filter

[Fulltimer50]

Anyone done anything to improve the A/C air filters in the ceiling. I find them very minimal. Screw holes that have to be used over and tend to wear out I think.

I have thought about increasing the size of my 6 return air grills but not done so yet. I have made the repeatedly used holes much better by using small wood blocks and placing them above the screw holes with some PL construction adhesive let set overnight and drill thru using a drill bit the size of the thinnest part of the screw.

I dread cleaning mine.

I've not ordered these yet, but would like to use this concept. Hinged latching door.

The wood fascia on the MAxxAir fans is a PIA too.

Like Cummins stated. Glue a piece of wood on to the back of the ceiling board, drill a small hole and you will be good to go. I did this about three years ago. Screws are still holding strong with no striping signs. I am not an Hvac engineer , but there is a balance between intake/suction and out-take/blow. It is a balance of CFMs. I believe that you want suction on the intake side as it moves the air better. Check the vents and ducts for leakage. I would think this would be your best improvement. There should be a thread about this on here some where.

This is a link on basic ducting understandings.

Again, I’m not an engineer.
Hope this helps.

You do not need to clean them if you do not want to. The material is like $1 at Walmart and you just cut it to size.
