Air Purifiers for Allergies

Allergy Air purifiers eliminate all allergens from the air and bring Relief to allergy and asthma sufferers.

Allergies caused by Airborne Allergens

There is a large group of allergies triggered by airborne allergens - microscopic particulates floating in the air, such as:

Removal of Allergens out of the Air

Mechanical air filtration is the easiest and the most effective way of removal airborne allergens out of the air.
True HEPA filter has a guaranteed efficiency of over 99.97% in trapping all microscopic allergens and dust from the passing through air as small as down to 0.3 micron in size.
This includes all allergens and lung damaging dust known to trigger the allergic reactions.
Therefore, large particulate filter is the most critical part of the air filtration system in air purifiers for allergy and asthma sufferers.
The size of True HEPA filter, the filter making process (warm or cold rolled), the quality of filter seal gaskets are the main factors that directly affect the air filtration efficiency and the air filtration capacity of air purifiers for allergies and asthma.
The size of True HEPA filter directly affects the amount of solid airborne contaminants (allergens) it can trap and ultimately, the HEPA filter's lifetime.
There are higher efficiency particle filters available in air purifiers for trapping sub-micron particles, such as:

• Super HEPA filter with 99.99% efficiency at 0.3 micron
• ULPA filter with 99.999% efficiency at 0.1 micron.

However, the utilization of a tighter Super HEPA and, especially ULPA filter instead of True HEPA filter may result in a reduced air flow and the lower number of air changes per hour (ACH) due to a higher back pressure from a more dense filter media.

Allergens Removal Rate

Maintaining the allergen-free air requires that the air purifier draw the entire volume of air in the room through the air filtration system few times an hour.
The number of Air Changes per Hour (ACH), indicating how many times per hour the air purifier can draw the entire volume of polluted air through the air filtration system is another factor of major importance.
It directly affects the rate of removal of air pollutants and the size of a maximum cleaning area, in which the air purifier can effectively maintain allergen-free environment.
The typical number of air changes per hour (ACH) required for allergy and asthma sufferers is 2. The higher number of air changes per hour may be needed for individuals with elevated sensitivity and severity of the allergic reaction.

For that reason, the air purifiers equipped with more powerful motor/fan and having a higher Air Flow Rating - CADR (Clean Air Delivery Rate) can provide the higher number of air changes per hour (ACH), and, therefore are better Air purifiers for Allergies and Asthma.
