Types of Air Purifiers

There are four main types of air purifiers: Activated Carbon, HEPA, Ionic, and Ultraviolet. Each type has its own benefits and mechanisms:

Activated Carbon

  • Smoke, odors, fumes, and gasses can all be removed from the air in your home using an activated carbon filter purifier.
  • Unless the model possesses a HEPA air filter, an activated carbon air purifier is less effective at removing pollen, dander, dust, or mold from the air than other types of air purifiers.


  • HEPA is an acronym for High Efficency Particulate Air. 
  • The air in your home is filtered using an advanced HEPA air filter. It is said that the HEPA filter can remove 99.7% of harmful particles larger than 0.2 microns from the air.
  • These filters need to be replaced on average once a month.


  • Ionic air purifiers emit negative ions into the air, which bond with positively charged, airborne particles like dust, making these particles so heavy that they eventually fall out of the air. 
  • Positively charged, airborne particles like dust are attracted to negative ions produced by ionic air purifiers. When the negative and positive ions combine, the particles become heavy and fall out of the air.
  • Ionic air purifiers are very quiet to operate since they have no motor.
  • They are less effective at removing larger particles like pollen and dander.


  • UV air purifiers remove harmful bacteria, viruses, and germs from your residence by using UV light.
  • By breaking molecular connections in their DNA, UV lights kills germs.
  • The UV light bulbs do need to be replaced periodically.

Choosing the Right Air Purifier

When considering purchasing an air purifier, there are several factors to keep in mind to ensure that you get the most out of your investment. Here are some key factors to consider:

  • Room size: It’s important to choose an air purifier that is appropriate for the size of the room it will be used in. A purifier that is too small for the room will not be effective, while one that is too large will be unnecessarily expensive and may produce too much noise.
  • Filter type: There are several types of air filters available, including HEPA (high-efficiency particulate air), activated carbon, and UV-C. HEPA filters are considered the most effective at removing airborne particles, while activated carbon filters are best for removing odors. UV-C filters use ultraviolet light to kill bacteria and viruses.
  • Noise level: Air purifiers can produce varying levels of noise, so it’s important to consider the noise level when choosing a purifier. If you plan to use the purifier in a bedroom or other quiet space, look for one that operates quietly.
  • Energy efficiency: Air purifiers can consume a significant amount of energy, so it’s important to choose one that is energy efficient. Look for purifiers with the ENERGY STAR label, which indicates that they meet energy efficiency guidelines set by the U.S. Environmental Protection Agency.
