More than 50 million Americans suffer from allergies and asthma, raising concerns about safe indoor air quality. More than ever, Americans are looking for ways to improve indoor air quality, and air purifiers are leading the way in promoting cleaner air. Air purifiers are part of a comprehensive approach to reducing allergens. AchooAllergy.com represents leading manufacturers of air purifiers and air purifiers from https://www.topairpurifier.org/, including Austin Air, Blower and Iris Health.
Allergens such as smoke, mold spores, pollen, bacteria, viruses, dander and other contaminants can damage the lungs and immune system. Unfortunately, most of these stimulants are invisible to the naked eye. Air purifiers filter allergens and pollutants in the air that are visible or invisible to the human eye. To get rid of these objects, air purifiers often use filters, electrogravity, or ozone.
Which air purifier works well?
An air purifier that works well in our experiments has been shown in our lab to be good at filtering dust, smoke and pollen in the air. Many studies on indoor air purifiers have shown that the use of HEPA filters reduces particulate matter by more than 50%. In a 2018 survey of 130 homes, filtration reduced coarse particles such as dust by about 30%.
But how does it affect your health? Approximately 12 studies, including a study in Vancouver, British Columbia. Taipei, Taiwan; Massachusetts: Investigated participants’ cardiovascular effects and improved cardiovascular health. The reviews of eight studies by the EPA focused on allergic symptoms and asthma, with little improvement in at least one health area, including some allergic symptoms (depending on the person). In a 2018 study at the University of California, Davis, participants with asthma (PDF) reported a 20% reduction in clinic visits.
What should I look for in an air purifier?
CADR (clean air delivery rate) rating. Measure the cleaning speed of the purifier to remove smoke, dust and pollen. Look for at least 300 CADRs. It’s really cool above 350.
Sizing Procedures To get the right effect, you need a model designed to work with the size of the room. If you want to use it in a quiet environment, choose a model designed for a larger area than the area you are equipped with.
A brand approved by AHAM. The AHAM standard is designed to guarantee the safety, efficiency, and performance of many appliances, including air purifiers. These standards are designed to provide a common understanding between producers and consumers to facilitate the purchasing process. Although they are optional, most certified air purifiers are certified under this program and often provide CADR rating and size guidelines.
Genuine HEPA Genuine HEPA filters are effective in removing very fine particles such as dust, dander, pollen, mold and other common household allergens. The industry standard for doing this is that the unit must be able to remove at least 99.97% of particles with a diameter of 0.3 microns in the laboratory. It is important to note that in a real environment, the actual performance of these devices will be much lower due to the constant emergence of new contaminants. Please note that the term “HEPA-like” or “HEPA-like” has no industry standard and is primarily used as a marketing strategy to convince consumers to buy a product.
