Air Purifiers 101: How They Work, Benefits & Types

Benefits of Air Purifiers

An air purifier is a device, which removes harmful airborne particles from the air in your home, with contaminants including dust, bacteria, dirt, and pollen. Air purifiers are manufactured as small, stand-alone units or larger units affixed to an Air Handler Unit (AHU) or to a Commercial HVAC unit.

How Air Purifiers Work

Your house can be a source of many air impurities and, as such, the air inside the home is generally dirtier than the air outside. Mold can develop from the accumulation of moisture. Dust particles and bacteria are often circulated in the house through heating and cooling. Smoking, cooking, and burning candles and fires pumps toxins into the air, and pets shed fur thereby giving off dander.

In order to reduce these contaminants and remove indoor air pollutants, air purifiers can be used. Air purifiers move the air in your home through high-efficiency particulate arresting filters and trap the particles. The purified air is then circulated back into the room, keeping the environment safe and healthy.

Benefits of an Air Purifier

Air Purifier Benefits

There are several benefits to having an air purifier in the home. These include:

  • Air purifiers help remove air pollutants – They have filters that clean and purify the circulated air by trapping particles present.
  • They remove up to 99.9% of dust particles –HEPA filters in the purifiers help remove 99.9% of impurities and dust particles from the air, including mold spores, pollen, pet dander, and dust mites. This is achieved by cycling the air in the home continuously.
  • They help neutralize smoke – Air purifiers help trap smoke in our homes before it gets trapped in the upholstery.
  • Air purifiers stop the spread of sickness, germs, and diseases –Bacteria and viruses can be transferred from one person to another through sneezing and coughing. Bacteria survives in warm, humid areas and can cause serious illness to the young and old. HEPA air purifiers with electrostatic purification can help neutralize a greater percentage of all airborne germs and bacteria.
  • They trap allergens released by pets – Pets bring about odors and dander, which can cause respiratory inconvenience or disease. Air purifiers help tackle these allergens, trapping them before they settle in your home.

Types of Air Purifiers

1. Filters

  • True HEPA/UV-C Air Purifiers – This air purifier can trap 99% of airborne germs and odor-causing bacteria and 99.97% of airborne allergens using its replaceable HEPA air filters with an ultraviolet germicidal light. It can be used in high allergen areas to eliminate odors, dust mites, smoke, pollen, dust, lint, germs, pet dander, and mold.
  • True HEPA Air Purifiers – This air purifier helps eliminate dust mites, pollen, and mold spores, using replaceable HEPA-rated filters. They help keep the home smelling fresh by removing the main causes of seasonal allergies and 99.97% of the airborne particles.
  • HEPA-Type Air Purifiers – This purifier is more economical but less-effective than True HEPA Air Purifiers. They operate well in lower allergen areas and have replaceable filters to trap 99% of small airborne particles, which include pet dander, smoke, dust, to help maintain clean air.
  • Permanent HEPA-Type Air Purifiers – Permanent HEPA-Type Air Purifiers help eliminate 99% of airborne particles including smoke, odors, lint, dust, and pet dander, with its reusable filters that require occasional cleaning.

2. Adsorbents

These purifiers use an adsorbent material to eliminate odors, chemicals, and smoke from the air. They use the adsorption method, which is the process of trapping a substance on the surface of another substance. The common adsorbent used in this case is activated charcoal.

3. Ultra-Violet Purifiers

Many microorganisms, like viruses and bacteria, are rendered harmless by ultra-violet radiation. Some air purifiers use UV germinal light, which eliminates airborne bacteria, germs, and viruses.

4. Ionizing Purifiers

The corona discharge method is used in this air purifier to send streams of negative ions into the air, which are attracted to anything with the opposite charge. The particles in the air get clumped together and become heavier, causing them to then settle out of the air.
