Honeywell Enviracaire 16200 Air Purifier

Pros: Compact, inexpensive and works efficiently.
Cons: Uses up a lot of electricity for a unit so small.

Wintertime or anytime indoor air becomes stagnant and potentially harmful, so a good air purifier is absolutely essential for the home.  After checking out the high-priced models and junking my tiny worthless wonder which I purchased ...

Pros: Great machine, excellent price and does not take up much room.
Cons: Running on medium it is a little loud.

Pro: Works great in my office (12' x 12'). I run the unit on low all the time and if a smoker comes into my office who just smoked outside I turn the unit to medium and within 30 seconds my office is smoke free and the unit is turned back to low.

Pros: Small enough to not hog the dresser up and almost silent.
Cons: The filters are pricey.

We purchased this product for our infants nursery since he was diagnosed with nigh time asthma. It is almost silent on the lowest setting and no louder than the compact office fans on the highest. It also features an ionizer that uses an electrical charge to pull dust particles out of the circulating air. There has been a noticeable difference in his nursery just today, less than four hours after setting it up. Less dust particles circulating in the sunlight and an overall cleaner smell to the room.
We purchased it at a much lower cost from Home Depot.
