Finding the right air purifier for asthma can be a daunting task. There are so many brands, manufacturers, models, and features to consider, and the process can quickly become overwhelming. To help people navigate this sea of options, this article lists factors that buyers should consider when making their selection.
Type of Filter Used
The type of filter used in an air purifier can affect its ability to remove allergens and other irritants from the air. HEPA filters are good at trapping particles larger than 0.3 microns, including bacteria and mold spores. HEPA filters can be made with a variety of materials, including paper and fiberglass. Electrostatic filters use electrical charges to attract particles from the air. Electronic ionizers create a charged field that attracts airborne particles. Activated carbon filters trap volatile organic compounds (VOCs) from indoor sources such as cleaning products or paint fumes.
Size of The Device
Some smaller models are portable; others are designed for permanent installation in a room such as an office or bedroom. Permanently-installed units tend to be larger than portable models. The latter may require more frequent emptying of their collection chambers due to their relatively small capacity for collecting particles over time.
Noise Level
Some models are noisier than others; people who are concerned about keeping things quiet while sleeping or watching TV should consider buying a quieter model. It’s also important to note that some portable units also have fans that produce audible noise when operating at maximum speed.
Additional Features
Some models include features such as germicidal UV lights or deodorizers. For instance, people who have pets at home should look for models that include antimicrobial treatments to stop pet dander from accumulating on the filter and recirculating through the room again and again until it’s trapped by the filter.
Power Source
Some air purifiers use electricity while others run on batteries. If the device will be used in a place without easy access to electricity, then look for one that runs on batteries or uses less power than others do.
