How the Technologies Differ.




True HEPA. The Doctor’s Choice. 1

The “gold standard” in air purification. Filters capture up to 99.97% of microscopic particles (as small as 0.3 micron in size, form the air that passes through the filter). Includes odour absorbing pre-filters.

The technology that is most often recommended by physicians.

Captures up to 99.97% of airborne allergens, 0.3 micron or larger, from the air that passes through the filters.

Mechanical Filtration (particles are forced through and trapped in a high efficiency filter).

HEPA Filters are replaced approximately once per year.

Includes odour absorbing pre-filter (replace every 3 months).

1 Based on Nov 2014 Cascade Survey Research results reporting 148 out of 171 (87%) surveyed physicians that recommend portable air purifiers to their patients, recommend True HEPA or HEPA-TYPE air purifiers.

QuietClean® & AirGenius.

Capture up to 99% @ 2 micron (featured in QuietClean® products) and 99.9% at 0.3 micron (featured in Air Genius products).

Best Technology for general air cleaning, featuring permanent, washable primary filters.

QuietClean® captures up to 99% of larger particles, from the air that passes through the filters. AirGenius captures up to 99.9% of particles, 0.3micorns or larger that passes through the filters.

Exclusive Honeywell Air Purifier Technology – Patented ifD® filter

Electronic Filtration (captures particles are attracted to and captured by the ifD® filter.

Permanent filter, simply rinse or wash clean.



HEPA-Type filters capture up to 95-99% pf particles (as small as 2 micron in size from the air that passes though the filter). Includes optional on-off ionization to boost cleaning power. Odour absorbing pre-filter can be purchased separately.

Good technology for general air cleaning.

Captures up to 95-99% of airborne particles, 2 micron or larger, from the air that passes through the filters.

Mechanical filtration with optional on-off ionization (particles are forced through and trapped in a filter).

Filters typically need to be replaced once every 4-6 months.

Optional odour absorbing pre-filter.

Control the source of allergens.

  • They all use a fan to:

    Pull dirty, stale air into the unit. Force the dirty air through a filter that captures pollutants. Return cleaner, fresher air back into room.
