Air filter replacement

[major hattitude]

Just wondering what everyone is using for filters for A/C units thanks for info

[Lmcruiser]

Don’t know about Hatteras filters but I have used window air conditioner filter foam cut to size. Got mine at Lowe’s but saw some at a hardware store about 2 weeks ago. I think the brand is Frost King. Comes in 24X15 in sheets.

Yes, i use foam and cut to size.

On my customers 114 MY i use a special filter foam but we infuse it with essential oils to give a nice scent. We also replace them every 30 days to keep them sanitary.

I use the cut to size stuff from Lowes as well. Not foam but a mesh type filter

Are you kids talking about the air supply grate before the evap station or the mesh on the evap station it self?

on returns , I use #10 quality single use filters cut to size, and spray with mediclean on installation. has improved air quality over last few years.

I had some scrap MERV 8 1" filter material left over from a sample set sent to me. The volume of the blower was noticeably reduced so I took it out for fear of too much pressure drop. Im gonna try the essential oil but will need to go back to foam in the return grille.

Aside from the OEM filter material on the evaps, I added some filtration to the returns. Half of my evaporators are a real PIA to get to.

Oops, put it on upside down...I mean I designed it to go either way. Yeah, that's it!

The media is room AC filter panel available anywhere and cut to size. I didn't like the loose fit you normally get using the spring clip arrangement.

I like the essential oil treatment mentioned above and look forward to trying it. Hope it doesn't melt the foam.

Very nice. Once again, I think I'll copy you.
