True HEPA Filter

It is important to note the differences between a True HEPA Filter and a HEPA-type or HEPA-like Filter when shopping for air purifiers. In order to be rated as a True HEPA filter, a filter must pass the Dioctyl Phthalate Aerosol test and it must exceed a minimum efficiency of 99.97% at a particle size of 0.3 microns with less than a one inch drop of air pressure. HEPA-type and HEPA-like filters, while lower in cost, are much less efficient than True HEPA filters, especially at particle sizes less than 1 micron. Removing particles that are less than 1 micron in size is important as these particles can enter into the blood stream and contribute to illness and/or disease.

Allergy UK

The Allergy UK seal of approval indicates that AeraMax™ has been scientifically proven to reduce exposure to pollen, mould, house dust mite, smoke, cat and dog allergens.

Energy Star

Fellowes® Air Purifiers are also Energy Star-qualified. Energy Star-qualified air purifiers are 40% more energy-efficient than non-qualifying models.

Sanitized

Fellowes® air purifier carbon filters are protected with Sanitized® Technology, which effectively reduces the development of bacteria, fungi, and dust mites on the carbon filter itself. This is important because, without this technology, microbes can settle on the filter and be re-circulated into the air.
