Recently, I saw the inside of my 11 year old AC and it was loaded with mold. And I had mold/fungus build up in my house in past years. I'm wondering if a built-in air cleaner would have helped. So now I'm trying to figure out if it's really worth forking over the $900. Do these air cleaners really work better than just the standard filter? Are they worth the money?
If you know anything about air cleaners such as this, please share your thoughts. I have seen many advertisements for portable air cleaners but I assume one that is built-in to the air handler, such as the Honeywell, would be more effective.
