According to the Environmental Protection Agency (EPA), indoor air pollution is among the top five environmental health risks we currently face. The best way to address the risk of breathing polluted indoor air is to eliminate the source of pollutants with ventilation and filtration.
An air purifier can reduce the concentration of airborne pollutants and allergens in a designated area. The amount of pollutants removed by an air purifier will differ, depending on the specifications of the particular unit.
Since 1996, we have seen countless air purifier models and brands be discontinued due to lack of market penetration or failure to perform as advertised. Once they are discontinued, customers tend to receive little-to-no support post-purchase, leaving them without replacement filters for their air purifier.

The list of air purifier technologies available can be long and robust. Some of the more common technologies available are High Efficiency Particulate Air (HEPA) filtration, electrostatic precipitators, and ozone generators. While many of these are advertised as beneficial, we do not recommend all technologies.

The pre-filter is a removable filter layer that captures larger particles, such as dust and hair, helping to extend the life of the main HEPA filter. Pre-filters are typically designed to be washable or vacuumed. Replacement costs are relatively low.
Activated carbon neutralizes odors and traps chemicals and gases. It is commonly combined with zeolite or potassium iodide in air purifier filters to optimize toxin removal.
Ultraviolet light (UV) can be used to neutralize bacteria that accumulate on air purifier filters. The key to effectiveness is exposure time, so benefits will vary depending on the specific air purifier model.
Ionizers charge airborne particles, causing them to clump into larger particles. This technology complements HEPA filtration, as it allows the larger particles to be more easily captured. However, ionizers are considered ineffective without HEPA filtration, as it does not remove a significant amount of particles. It is important to also note some ionizers emit ozone, and only ozone-safe ionizers should be considered for residential use. All of the units on AirPurifiers.com are ozone-safe.
A filter life indicator is a digital display on your air purifier that notifies you when your filter is full and requires replacement. Filter life indicators are often based upon a manufacturer’s recommended filter life. In some higher end units, the filter life indicator reflects actual usage and filter capacity.
Some air purifiers feature a built-in timer, which can be set to automatically shut off the unit after a designated amount of time.
