Mechanical filters are one of the most popular methods for capturing airborne particles. HEPA filters, specifically, are very effective at removing small particles such as allergens and dust. That’s because of the Brownian motion, which forces the small particulates into the filter’s fibers.
Regular filter replacement is important to ensure the optimal performance of these filters. Mechanical filters are very quiet and energy efficient, so they tend to be the most practical option for many homes.
Electronic Air Cleaners
These devices use electrostatic precipitation to collect particles. Besides being extremely quiet, ionic purifiers excel at trapping airborne dust and other irritating allergens.
Do pay attention to any ozone production, as ozone can be hazardous to health. Electronic air cleaners usually need to be replaced less frequently than mechanical filters.
Gas-Phase Air Cleaners
Gas-phase cleaners filter gaseous pollutants and odors, including VOCs, from the air through the use of adsorbent materials, such as activated carbon. Selecting the proper adsorbent material is crucial to targeting specific air quality problems.
These systems are commonly used alongside mechanical filters for complete air purification.
UV Light Purifiers
Ultraviolet light purifiers work by shining UV light to deactivate airborne pathogens. While they are effective against bacteria and mold, they are not effective in removing dust or gases.
They require vigilant maintenance to perform as intended, and they are most effective when implemented in concert with other technologies.
Photocatalytic Oxidation
This process relies on UV light and a catalyst, usually titanium dioxide, to oxidize and break down pollutants. It’s a safe, fast and powerful solution to eliminate VOCs and odors, enhancing indoor air quality.
To keep these technologies functioning at optimal levels, specialized maintenance is needed.
Pros and Cons of Each Technology
