Size Matters

Ordinary HEPA filters
can only filter 0.3 micron particles and larger.

IQAir's HyperHEPA
technology filters the
smallest airborne particles
that exist.

Viruses

Viruses: 0.005 – 0.3 microns

Like bacteria, viruses are organisms that spread airborne diseases as mild as the common cold and as serious as severe acute respiratory syndrome (SARS) through coughs, sneezes and improperly maintained ventilation systems.

Tobacco Smoke

Tobacco Smoke: 0.01 – 1 micron

Sidestream smoke has higher concentrations of cancer-causing agents (carcinogens) than mainstream smoke. And, it has smaller particles than mainstream smoke, which make their way into the lungs and the body's cells more easily.

Soot

Soot: 0.01 – 0.3 microns

Long-term exposure to urban air pollution containing soot increases the risk of coronary heart disease, according to a major study published in New England Journal of Medicine in 2007.

Pet Dander

Pet Dander: 0.1 – 25 microns

Pet dander is the old skin and fur that pets shed. Animal dander is very small and can become attached to your clothingeven if you do not own a pet. Dander can be found everywhere: floors, carpets, walls, furniture, bedding, even the ceilings. Pet dander is a known asthma and allergy trigger.

Dust Mites Allergens

Dust Mites Allergens: 0.2 – 25 microns

House dust mites are considered to be the most common cause of asthma and allergic symptoms worldwide. Dust mites themselves do not cause an allergic reaction, however, their dung-pellets are an irritant to sensitive people and can cause breathing difficulties. They thrive in warm, humid, dark conditions such as mattresses, carpets, sheets, pillows, and upholstery.

Bacteria

Bacteria: 0.5 – 10 microns

People spread bacteria through the air when they cough and sneeze, transmitting respiratory diseases and triggering symptoms in asthma sufferers. Bacteria can also grow inside poorly maintained ventilation systems, which spread it into the circulating air.

Household Dust

Household Dust: 1 – 100 micron

Dust may worsen hay fever. Circulating outdoor air through a house by keeping doors and windows open, or at least slightly ajar, may reduce the risk of hay fever-causing dust. In colder climates, occupants seal even the smallest air gaps, and eliminate outside fresh air circulating inside the house. So it is essential to manage dust and airflow.

Mold Spores

Mold Spores: 8 – 80 microns

Mold and fungus are commonly found in most homes and may be found in the air ducts of your heating/cooling system. They tend to float throughout the house, and form new colonies where they land. Fungus spores have been known to increase the chances of developing asthma.

Pollen

Pollen: 10 – 100 microns

One of the most common allergens is pollen. It affects the nose, eyes, and mouth making it difficult to breathe. Most pollen that produces allergic reactions is from trees, grasses, and weeds.
