Is this air filter dirty?

7 years ago

I had an Aprilaire 4 inch media filter installed last April with my new system. I know they should be changed every 6-12 months but I am not sure what how they should look for when to replace.

How does this filter look? Ready for changing or wait until April for full 12 months.

I have a similar filter, also Aprilaire. I change them twice a year. Yours looks pretty clean to me. Do you have central air that uses that filter, i.e., how many hours are on your syatem?

Yes I also have central air and ran it quite a bit this summer. My furnace also mostly stays in stage 1 so longers run times. No pets or smoking.

It’s on 9 months so I just went ahead and changed it. It probably had some life left but there was a decent amount of dust build up in there once I took it out and examined it closely.

My furnace filters last for years, now that I clean them quarterly with a vacuum cleaner.
