Holmes HAP 220 Electrostatic Air Cleaner with ionizer. Like new. The following review speaks to the efficiency and reliability of this unit. $50.00.
I have asthma, and it is a life saver when smoke and odors from cooking threaten my breathing. Small enough to take with me when I travel. It's useful for removing odors and dust from the air. I really depend on it. Reasonable price, and totally reliable. The filter is easy to change, (you can extend it's useable life by vacuuming it!) The pre-filter just rinses out, and the case wipes clean easily.
