The Honeywell 18155 Air Purifier is a mid powered, affordable and economical air purifier. It provides 6 air changes per hour in a room with 187 square feet, these are numbers for high speed operation, but at these speeds the 18155 is a bit noisy and not suitable for a sleeping room. It features the innovative NoDraft technology that prevents cool exhaust drafts, plus a permanent HEPA filter that does not need to be replaced. It is perfect for medium rooms and it is great to have in children playrooms (see what users had to say).

Great Pack of Features

This air purifier reduces airborne germs in your rooms and removes particles that can be as small as 0.3 microns, while the advanced carbon pre-filter gets the larger particles and clears odors. It was designed and built with Surround Seal that increases the efficiency of the whole purifier by not allowing any air to come out of the purifier cycle without passing through all the filtering stages. It is also virtually maintenance free, due to the Intelli-Check electronic filter clean reminder.

Lightweight, Easy to Use Air Purifier

The Honeywell 18155 is a good buying option for anyone looking for an efficient air purifier that works well in medium sized rooms and delivers great results. Removes up to 99.97% of all air particles, the HEPA filter does not need to be replaced, has virtually no maintenance, and the air cleaning is done without any cool-air exhaust. It is an air purifier that you should take a look at before considering all the others for any medium sized rooms.
