Operational Mechanism: How do Air Purifiers Work?

Air purifiers can help in filtering out the majority of indoor pollutants and airborne particles.

For a better insight into an air purifier unit, let’s first learn about the filters used in it and the most known types. I have compiled them in an orderly manner for your understanding!

HEPA Filters or High-Efficiency Particulate Air Filters

Here are some important facts about the HEPA filters that you should know:

Mold and purifier
  • An ultrafine mesh is present in True HEPA air filters that catch any mold spores, dust, pollen, pet dander, and more.
  • With this type of filter installed in the air purifier, you can easily ensure that 99.97% of indoor air pollution (0.3 microns and larger size) is filtered from the air.

Always make sure that you are investing in an air purifier that has this type of filter and nothing less than this.

Important! Double check if the specifications mention “HEPA-type” or “HEPA-like” as both have a very large difference. Both these types do not fulfill the certification requirements and standards of a “True HEPA filter”.

Activated Carbon Filters for Better Air Quality

Let’s learn about these filters by reading the critical piece of information below:

Carbon Filters
  • Air purifiers with this type of filter are best for indoor spaces that have smells or dangerous gases.
  • A kitchen or a room with a fireplace is an ideal place to install units with these types of filters.
  • The working mechanism is called “Adsorption“. It uses a method that sticks indoor air pollution to the carbon lattice.
  • Carbon material used in these types of filters specializes in absorbing cooking smells, unpleasant smells, and fumes from dangerous gases such as radon or volatile organic compounds.
Pro tip: You should choose an air purifier that has both a True HEPA filter and this type equipped in the unit for effective cleaning.

Ionic Air Purifiers: Does it Improve Poor Indoor Air Quality?

These types of air purifiers make use of ionizers that charge the particles electrically making them stick to metal plates present in the purifying unit.

Note: I would recommend you check out the specs of such purifiers in detail as they are also known to release Ozone which is considered harmful.
