Thread: a/c filter

My a/c turned black within a week, both sides equally blackened. It appears to be a very fine dust. Any ideas?

Is it a new system? Is it a new home? Is there a sulphur smell in the home? Has there been recent construction in the home? Has there been recent construction on the street/road?

We need a lot more background and maybe photos.

You are not clear in your question.
A/C what type? What part of system ?
Both sides, sides of what?
Fine dust where? How much? On What?

This is on the filter, correct?

OK, I will assume this is the filter we are talking about.

Do you have an ozone air cleaner that you are running?
Do you burn candles?
Do you have a gas fireplace?
Are you a bad cook?

Let us know and if you have any photos that will help....

If a filter and both sides, then possible mold??????
