How Does an Air Purifier Work?
Air purifiers utilize various technologies to cleanse the air. The core component of most air purifiers is a series of filters that trap and remove different types of pollutants.
Air is drawn into the purifier and passed through these filters. The most common type is a HEPA (High Efficiency Particulate Air) filter, which can trap tiny particles down to 0.3 microns in size. This includes most common allergens and many types of bacteria.
Some air purifiers also feature additional technologies, such as activated carbon filters for removing gases and odors, or ultraviolet (UV) lights to kill bacteria and viruses.
After the air has been filtered, it is circulated back into the room. The purifier continues to cycle the air in the room, progressively reducing the concentration of pollutants.
In essence, an air purifier works continuously to provide cleaner, healthier air in your home. For more information on HVAC systems and how they can be optimized for your home, explore our articles on HVAC system sizing and HVAC maintenance checklist.
Types of Air Purifiers for Home Use
Air purifiers come in various types, each designed to target specific pollutants. Understanding these types is crucial for making an informed decision about the air purifier best suited for your home. Here we’ll focus on four main types: mechanical filters, activated carbon filters, ultraviolet germicidal irradiation, and photocatalytic oxidation.
Mechanical filters, also known as particulate air filters, are perhaps the most common type of air purifier. They work by trapping airborne particles such as dust, pollen, and pet dander in a fine mesh filter, effectively removing these pollutants from the circulating air. The most recognized type of mechanical filter is the High Efficiency Particulate Air (HEPA) filter, which can remove 99.97% of particles that have a size greater than or equal to 0.3 µm. This makes them particularly effective for allergy sufferers.
When using mechanical filters, regular replacement of the filter is vital to maintain their effectiveness. For more on this, visit our guide on HVAC filters.
Activated Carbon Filters
Activated carbon filters are a popular choice for removing gases, odors, and larger particles. They work through a chemical reaction called adsorption, where certain particles are attracted to activated carbon and bond with it. This makes them especially effective at removing volatile organic compounds (VOCs) and odors from the air, which mechanical filters may not be able to catch.
Ultraviolet Germicidal Irradiation
Ultraviolet Germicidal Irradiation (UVGI) purifiers use ultraviolet (UV) light to kill or inactivate airborne pathogens, such as bacteria, viruses, and molds. The UV light damages the DNA and RNA of these microorganisms, preventing them from reproducing and therefore effectively neutralizing them.
It’s important to note that while UVGI purifiers are effective against microorganisms, they do not remove particulate matter or gases. Therefore, they are often used in conjunction with other types of air purifiers.
Photocatalytic Oxidation (PCO) is a newer technology in air purification. PCO purifiers use a catalyst (usually titanium dioxide) and UV light to create a chemical reaction that destroys gaseous pollutants by converting them into harmless substances. These purifiers can be effective against VOCs, bacteria, viruses, and odors.
Like UVGI purifiers, PCO purifiers do not remove particulate matter, so they are often used in combination with other types of air purifiers.
As you consider the best air purifier for your home, keep in mind that no single type can remove all types of pollutants. A combination of purifiers may be necessary to improve the overall air quality in your home. For more information on maintaining optimal air quality, explore our guide on home heating and cooling.
