Honeywell HHT-011 HEPA Air Purifier
The Honeywell HHT-011 air purifier is a good alternative to other more expensive units. This is a basic unit, that doesn’t include a remote control or an advanced LCD display, but it does have an advertised permanent filtration system, a washable pre-filter and an optional ionizer for a fresher air.
This small air purifier performs best in small rooms; up to 8 x 10 feet. Besides being quiet, the HHT-011 air purifier also features a cleaning indicator light that alerts you when the HEPA filter needs to be cleaned.
Cleaning the HEPA filter is rather simple; you just have to remove it and vacuum it. It’s important to mention that you can’t wash the HEPA filter, only the slim pre-filter.

HEPA filters have been tested to remove up to 99% of airborne particles 2 microns or larger. Like: dust, pollen, smoke and mold spores.

Pros
