How Do Air Purifiers Work?

Air purifiers have become increasingly popular in recent years, as people are more concerned about the quality of the air they breathe. Many potential buyers often wonder if air purifiers dry the air in their homes. In this blog section, we’ll delve deep into how air purifiers work to give you a better understanding of the process and whether they’re worth the investment.

Mechanism Behind Purifying The Air

Air purifiers work by drawing air from the surrounding environment and passing it through a series of filters that are designed to capture various pollutants. As the air passes through the filters, particles such as dust, pollen, pet dander, bacteria, viruses, and smoke are collected.

Depending on the model, there may be additional steps in the process, such as the use of uv-c light or ionizers, to kill or neutralize any remaining contaminants.

Types Of Air Purifiers Available In The Market

There are various types of air purifiers on the market that utilize different methods to purify the air. Some of the most common types of air purifiers include:

  • Hepa air purifiers: These types of air purifiers use high-efficiency particulate air (hepa) filters to remove particles from the air. Hepa filters are capable of capturing particles as small as 0.3 microns in size, such as dust, pollen, and pet dander.
  • Activated carbon air purifiers: These purifiers use activated carbon filters to absorb odors, gases, and chemicals from the air. They’re particularly useful for removing cigarette smoke, cooking smells, and vocs (volatile organic compounds).
  • Electrostatic air purifiers: These purifiers use an electrostatic charge to attract and capture particles in the air. They’re particularly useful for removing smoke and allergens, but they can also produce ozone, which can be harmful to some people.
  • Uv-c air purifiers: These purifiers use uv-c light to kill bacteria and viruses in the air. They can be effective at reducing the spread of illnesses, but they may not be as effective against allergens and other particles in the air.
