Austin Air HealthMate is an air purifier with a true HEPA filter. True HEPA filter can trap up to 99.97% of particles in air larger than 0.3 microns and it meets all HEPA standards. Dont be foled by its small size as this air purifier is specially intended for larger rooms and it is available in four colors. Silver, sandstone, black and white color.
The HealthMate filter should last for about 5 years. This means you won't need to replace the filter too often even if you use it 24/7. Yes, you read correctly. It can be let to work non-stop. In fact, Air Austin (manufacturer) recommends their customers to leave their air cleaner on all the time to get cleaner and freshier air as possible. I cant say will that affect your electric bill to be higher. HealthMate HM 400 uses 115W of power on high.
The Health Mate HM 400 can operate at 3 speeds and on the highest speed it can purify up to 1500 sq ft of a room. It's manufactured in the USA and comes with a medical grade 60 sq ft. HEPA filter. If VOCs is your primary concern, or you or someone in family suffers from asthma or pulmonary disease, the Healthmate HEPA Air Filters is great choice for contaminant removal. Specially gaseous, VOC contaminants found in paints and cleaning supplies. Motor is quiet and shouldnt produce any noise that would disturb piece or your sleep if you use it in bedroom. It has wheels so you can easily push where it is needed.
