According to a post by the American Academy of Allergy, Asthma & Immunology (AAAAI), 10 to 30 percent of the planet’s population suffers from allergic rhinitis.
Exposure to dust mites pollen or pet dander can trigger a stuffy and runny nose, itchy eyes, and sneezing.
Doctors usually recommend nasal sprays, eye drops, and drugs to alleviate the signs. Another remedy is to avoid exposure to known allergens by staying away from furry animals, thoroughly cleaning your house, and staying indoors.
Despite your best efforts, exposure to allergens remains inevitable. However, an ideal solution is to use air purifiers for allergies.
The most effective air purifiers have great and helpful capabilities. Read this guide to find out more:
1. HEPA Air Filter
Compared to standard air filters, High-Efficiency Particulate Air (HEPA) filters are better at trapping at least 99.97% of airborne pollutants that are as small as 0.3 microns.
Originally developed as part of the Manhattan Project to remove radioactive materials from the atmosphere, scientists have developed functional applications for HEPA filtration technology.
Some air purifiers, for instance, have HEPA air filters to trap pet dander, dust, mould, and other allergens.
According to a study by the Asian Pacific Journal of Immunology and Allergy in 2018, the usage of HEPA air purifiers for allergies has decreased symptoms of allergic rhinitis.
2. Clean Air Delivery Rate (CADR)
Another factor to consider apart from the filter is the delivery rate. Each air purifier has various CADR to remove allergens.
The air purifiers for allergies have a CADR rating of over 300. The score represents the air volume in cubic feet per minute (CFM) that it can clean from the air.
The Association of Home Appliance Manufacturers (AHAM) administers the CADR rating, and the Air purifiers will display three CADR numbers – for tobacco smoke, dust, and for pollen, consumers should select air purifiers that have a CADR rate of at least two-thirds of the room’s area.
3. PECO Filters
Another sort of filter is called photoelectrochemical oxidation (PECO). Using nanotechnology, PECO destroys allergens, which are HEPA traps that are 1000x. Moreover, PECO breaks down volatile organic compounds (VOCs), which can be poisonous chemicals released by gases.
In a 2018 study published by the National Institute of Health, there was a significant reduction in symptoms when people used air purifiers for allergies that had PECO filters.
4. Plasma Wave Technology
At the molecular level, the destruction of pollutants and allergens occurs with this technology. With the usage of electricity, positive and negative ions attach pollutants to air and eliminate hydrogen, resulting in cleaner air.
The usage of plasma wave air purifiers for allergies can enhance your health as you get to breathe in some nice, fresh air.
5. Ultraviolet Germicidal Irradiation (UVGI)
According to a post by the National Institute of Health, UVGI significantly reduces airborne bacteria and bacterial spores. By destroying their DNA, ultraviolet light kills germs, mould, and viruses.
The US government was using UVGI air purifiers within their buildings. The Center for Disease Control has recommended using UVGI air purifiers for allergies to destroy allergens and pathogens.
With developments in research, manufacturers are currently producing greater air purifiers for allergies. They improve air quality and prevent more acute lung ailments apart from decreasing symptoms.
Among the different models of air purifiers, you should pick one based on your needs and budget.
