Rising asthma rates and concerns about indoor pollution and airborne viruses have led to increased demand for air purifying technology, especially HEPA (high-efficiency particulate arresting) filters.
These have become the standard for reducing the concentration of particulates in indoor environments, while activated carbon filters are more effective in capturing harmful gases and odors.
Most high-quality air purifiers contain both.
When used together, HEPA and activated carbon filters can remove up to 99.97% of particles 0.3 microns or smaller, along with most larger molecules.
Air purifiers bring many benefits to the homes, protecting those with allergies, asthma and other lung-related conditions from triggering substances while reducing the likelihood others will develop such health problems.
- Relieve asthma symptoms — The Centers for Disease Control and Prevention estimates one in 12 Americans has asthma. Dust mites, pet dander and pollen are common triggers for asthma attacks.Vacuuming carpets and furniture can eliminate particles on those surfaces but can’t capture the ones floating in the air, and sometimes it even adds to them.
- Capture harmful gases and chemicals — In congested areas, the nitrogen dioxide and carbon monoxide released by vehicular traffic can infiltrate homes, schools and businesses.Other volatile organic compounds, or VOCs, can be found in many household cleaners and other products and can lead to health problems through repeated exposure, including cardiovascular and neurological disorders or cancer.Activated carbon filters in air purifiers remove these fumes from home environments.
- Improve sleep — By reducing particulates that cause hay fever and other symptoms of allergies or asthma, air purifiers let those suffering from those conditions sleep undisturbed by sneezing, coughing and other annoyances that interrupt your all-important slumber.
- Dial back secondhand smoke — If you have smokers living or frequently visiting with you, using an air purifier with an activated carbon filter can remove most of the toxins and odors from your indoor atmosphere.
- Eliminate asbestos particles — This material was widely used in construction of houses and businesses from about 1900 to 1980. If you live or work in an older structure you believe contains asbestos, an air filter capable of catching these particles is a good idea.
