My air purifier smells like cigarette smoke. How do I get rid of that smell?
My grandmother gave me her old Holmes air purifier but even with a new HEPA filter it blows out air that smells like cigarette smoke. How do I properly clean it so that it smells like it’s supposed to?

I think you should try Glade (I recommend the Clean Linen kind it smells really good)
Hope this helps
clean it with some vinegar and water.
First of all, you need to find out where the smell is coming form. Is it from the air filter itself or maybe inside the air purifier. If you know how to open it up, you can find the source of the smell. If not, let others help you.
Perhaps the old Holmes air purifier is choked up inside so you might want to get a new one. There are quite a few nice air purifiers for homes you can get cheaply. You can learn more at: http://www.airpurifiers4u.com/
