Best HEPA Air Purifiers

The best HEPA air purifiers should be your first look if you’re shopping for a portable air purifier to use throughout your home, getting one with a HEPA (High Efficiency Particulate Air) filter is definitely the way to go. According to Wikipedia, HEPA filters are composed of a mat of randomly arranged fibers. The fibers are typically composed of fiberglass and possess diameters between 0.5 and 2.0 micrometers. HEPA filters, as defined by the US Department of Energy standard adopted by most American industries, remove at least 99.97% of airborne particles 0.3 micrometers (µm) in diameter. Keep in mind: products that claim to be “HEPA-type”, “HEPA-like”, “HEPA-style” or “99% HEPA” do not satisfy these requirements and may not have been tested in independent laboratories.

Opting for a HEPA air purifier is a smart idea because HEPA filters are time-tested and extremely effective at trapping small particles that are drawn into an air purifier. The best HEPA air purifiers have filters that are finely pleated meaning they works by forcing air through a fine mesh that traps harmful particles like pollen, dander, dust mites, and smoke. According to WebMD, using a HEPA filter in your home can remove most airborne particles that might make allergies worse.

The best HEPA air purifiers will be quiet, easily portable, energy-efficient and have customizable features (like fan speed, air quality sensors and indicator lights) that help you utilize it to the best of its ability and your needs. Take into consideration your indoor and regional specifications, which can then help you easily select the best HEPA air purifier for your home. At AllergyBuyersClub, we offer a wide variety of HEPA air purifiers that suit a range of budgets, room sizes and gadget-lovers.
