Product review (1 stars): No recommended for use in Aircare.
Thought I was getting a bargain, but not so.  We live in the desert southwest.  We have to run our humidifier on high all the time to get the whole house up to 40%.  If we run it on low, the house doesn't get above 30%.  We have an Aircare and these wicks just don't do the job like the brand name does.  Sad to say Aircare has doubled the price of their wicks since I first purchased them on Amazon 1 year ago. Guess I'll look elsewhere for the real thing.
