When it comes to eliminating dust from your space, the best room air filter is a HEPA filter. High-efficiency HEPA air filters are designed to work great in a stand-alone air purifier, trapping 99.97% of airborne particles. These filters are certified to capture 99.7% of particles as small as 0.3 microns, making it possible to remove lamp dust from your space. To ensure the best results, pay close attention to the power of a purifier, which can be checked in its clean air supply ratio (CADR).
According to the EPA, HEPA filters can remove 99.97% of dust particles that measure 3 microns in diameter. In addition to using a HEPA filter, finer filters can trap the smaller particles that pass through the prefilter.
What to Look for in an Air Purifier
When it comes to a dusty air purifier, look for one with a HEPA filter. They remove more than 99.97 percent of airborne particles, meaning they can trap dust, pollen, mold, bacteria and smoke suspended in the air.Many premium air purifiers use HEPA (high efficiency particulate air) filters, although there are other purification methods that do not use filters, such as ion purifiers. Look for an air purifier with a filter change indicator, which will let you know when the air purifier needs a new filter. We chose air purifiers with a variety of practical functions, such as several modes, fan options, filtering stages, and intelligent connectivity. All air purifiers can remove particles from the air and the more expensive ones can remove particles and gas.
Blueair does not use traditional HEPA filters, but rather the brand's HEPASilent double filtration technology.
How to Choose an Air Purifier
Some air purifiers control dust better than others, depending on the technology and filter system. This unit combines HEPA filtration with carbon filtration and has a pre-filter to capture larger dust particles. These devices are built to last, but you can expect to perform basic maintenance, such as changing the filter periodically.On the other hand, an air purifier with the capacity to filter 1,000 square feet will be excessive and will probably take up too much space. While people can improve indoor air quality, it's impossible to remove all harmful particles from the air. Once the filter has reached its purifying capacity, it must be placed in a plastic bag, sealed and discarded.
The Benefits of HEPA Filters
Generally speaking, HEPA filters are made of fiberglass and are capable of trapping particles as small as 0.3 microns in some cases, which means you can use an air purifier to reduce odors and even germs.Attached to the HEPA is an activated carbon filter that contains real carbon granules instead of agglomerated carbon.
