They are known for their exceptional ability to capture small airborne particles, making going with them an incredible decision for allergy sufferers and those worried about overall air quality.

How HEPA Air Purifiers Work:

  • HEPA filters are made of fine fibres that create a dense web-like structure. These channels can trap particles as small as 0.3 microns, including dust, pet dander, mould spores, and, surprisingly, a few microscopic organisms.
  • Air is drawn into the purifier, passes through the HEPA filter, and the captured particles are trapped. Clean, purified air is then released back into the room.

2. Activated Carbon Air Purifiers: Eliminating Odors and Gases

Activated carbon air purifiers are designed to target odours, gases, and volatile organic compounds (VOCs). They work through a process called adsorption, where chemicals adhere to the porous carbon surface.

How Activated Carbon Air Purifiers Work:

  • Air passes through the activated carbon filter, which has a large surface area with tiny pores.
  • Gases and odorous substances in the air are attracted to the carbon surface and become trapped within the filter.
  • Clean, odour-free air is released back into the room.

Activated carbon purifiers are particularly useful in kitchens, bathrooms, and areas with strong odours.

3. UV-C Air Purifiers: Battling Microbes with Ultraviolet Light

UV-C air purifiers utilize ultraviolet (UV) light to kill or inactivate bacteria, viruses, and mould spores. They are commonly used in healthcare settings and can help maintain sterile environments.

How UV-C Air Purifiers Work:

  • UV-C light is emitted within the purifier, and as airborne microbes pass through the unit, they are exposed to the UV-C light.
  • The UV-C light damages the DNA or RNA of the microbes, rendering them unable to reproduce and causing their destruction.
  • Clean, microbe-free air is then circulated back into the room.

UV-C purifiers are highly effective at disinfecting the air but may not capture particulate matter like dust or pollen.

4. Ionic Air Purifiers: Using Charged Ions to Remove Particles

Ionic or electrostatic air purifiers release negatively charged ions into the air. These ions attach to airborne particles, giving them a negative charge. The particles are then attracted to positively charged plates or surfaces within the purifier.
