Do Air Purifiers Improve Your Health?

Air cleaning devices, such as air purifiers, can help improve indoor air quality by eliminating or reducing pollutants and allergens. These substances can worsen symptoms of allergies or asthma, and can even contribute to more serious lung diseases and certain types of cancer. Some air purifiers, under the right conditions, can effectively remove certain respirable size particles (e.g., tobacco smoke particles).These invisible particles are a cause for concern because they can be inhaled deep into the lungs. Removing these particles can reduce the health-related effects of exposed individuals.

These effects can range from eye and lung irritation to more serious issues, such as cancer and decreased lung function. Two studies by Brauner et al. and Allen et al. found that air filters reduced indoor fine particle concentrations by 60%. Filtration was associated with a 9.4% increase (95% confidence interval, 0.9-18%) in the reactive hyperemia index and a 32.6% (4.4-60.9%) decrease in C-reactive protein. When considering an air purifier, you need to take into account not only the purchase price but also operating costs and filter replacement costs.

The World Health Organization (WHO) fact sheet reveals a stronger link between exposure to air pollution and cardiovascular diseases, such as strokes and ischaemic heart disease, as well as between air pollution and cancer. Research shows that filtering air can help remove harmful particles from indoor spaces, especially allergens, smoke and mold. If you also want to avoid odors and fumes, try air purifiers with HEPA and activated carbon filters. One way to ensure that air pollution and germs don't enter your home is to invest in an air purifier. This air purifier function is most useful when there is no access to additional outside air ventilation, such as if there are no windows, or if the outdoor air quality is poor. You can also look for air purifiers and filters that are certified asthma and allergy friendly devices from the Asthma and Allergy Foundation of America. In air filters, the air was first filtered by a coarse-grained pre-filter, followed by a Rota filter, in which small dust particles were captured by high-speed rotation. Regular air purifiers already help you and your family stay safe, but ultraviolet light purifiers go the extra mile to kill germs instead of just filtering them out.

Because of all the elements that air purifiers remove from homes that can trigger asthma attacks, they are one of the best tools to eliminate or alleviate asthma symptoms. Air purifiers with HEPA filters can remove 99.7 percent of particulate matter (PM) suspended in the air circulating in your home environment. The fan (or sometimes an internal fan system) draws in air and that air passes through the internal filters.


air filters are energy efficient, but filters need to be changed once every three months for optimal benefits. Droplet cores: small droplets of moisture carrying infectious pathogens of approximately 1-5 μm in diameter remain suspended in the air for several hours by virtue of their size and are carried by air currents over considerable distances. Ultraviolet light air purifiers may not be as effective as HEPA air purifiers because many bacteria are resistant to UV rays. In addition, there are other things happening in your home that can affect effectiveness, such as ventilation (windows open or closed) and new particles that constantly emerge, so the air may not be as filtered as the claims lead you to believe.
