Overview#

Many homeowners are unaware that the concentration of certain pollutants is often two to five times higher indoors than outdoors. Portable air purifiers can remove those pollutants from a single room to larger spaces. If you are an allergy sufferer, an asthmatic, or have local air quality issues from wildfires or smog, these devices can clean the air in your living space.

 

Particulate matter (PM) is one of the air pollutants monitored by the EPA. The EPA considers particles smaller than 10 micrometers to be of concern as they can easily enter the lungs. Coarse particles (PM10) are typically found in dust from roads, farms, dry riverbeds, construction sites, and mines. Fine and ultrafine particles are even smaller at PM2.5 or smaller. US fine particle pollution comes primarily from cars, trucks, buses, construction equipment, burning fuels such as wood, heating oil or coal, and fires in forests and grasslands. Exposure to particle pollution can cause a range of health effects across populations. Coarser particles (PM2.5-10 micrometers) can irritate your eyes, nose, and throat. Fine particles (PM2.5 or smaller) are considered the most dangerous because they can infiltrate deep into lung tissue.

 

Volatile organic compounds (VOCs) can also impact indoor air quality. Concentrations of VOCs indoors can be up to ten times higher than outdoors (Source: EPA). Many common household products emit VOCs, including paints, varnishes, and fuels. The health effects of VOC exposure include eye, nose, and throat irritation. They can also cause damage to the liver, kidney, and central nervous system. Some organics are known to cause cancer in animals, and some are suspected or known to cause cancer in humans. 

What are the different types of air purifiers?#

There are many types of purifiers, but the most common are those with either mechanical or carbon-activated filters or both. Mechanical filters are often HEPA filters. HEPA is an acronym for High-Efficiency Particulate Air and is a technology that has been used for many years to filter particles. True HEPA filters must meet a standard of trapping at least 99.97% of all particles larger between 0.3 and 10 microns. H13 True HEPA filters are considered medical grade and must meet a standard of trapping at least 99.95% of all particles with a minimum size of 0.1 microns in diameter. Carbon-activated filters help to eliminate odors and are used to clear smoke and chemicals out of the air. Some devices also have a UV-C Light which helps reduce airborne bacteria, viruses, and mold spores. As lower-cost sensors have become more widely available, and with the rise in airborne diseases, the U.S. air purifier market is expected to grow nearly 9% by 2028.


How often do you need to replace filters in portable air purifiers?#

Many factors might affect how often the filters need to be replaced. If you notice filters are getting clogged, more frequent cleaning or replacement might be necessary.  Following the manufacturer's guidance for when to replace or clean filters is recommended.  Some models allow water cleaning or using a vacuum on pre-filters, but inner filters need to be replaced. It might be helpful to schedule regular checks on air filters as part of seasonal maintenance. 


Checklist: Is indoor air quality a concern in your home?#

You may be wondering what you are breathing in at home. If you spend a lot of time indoors, and research indicates people spend about 90 percent of their time indoors, an indoor air quality monitor can help you learn more about the air you breathe. Consider the following checklist and whether you can take steps to eliminate some of your indoor air quality problems at the source. 

❐ Do you have any health symptoms such as poor sleep, headaches, sneezing, or allergies?

❐ Are there very young children, older adults, and people with cardiovascular or respiratory disease who spend most of their time indoors?

❐ Are there any indoor smokers?

❐ Are cleaning supplies, paints, insecticides, and other commonly used products stored indoors?

❐ Does it smell musty? Is there visible mold or mildew?

❐ Is indoor humidity 50 percent or higher?

❐ Are your fuel-burning appliances (stove, water heater, furnace) properly vented and regularly serviced?

❐ Have you recently installed new carpeting, remodeled, bought new furniture, or painted?

❐ Are there any outdoor sources of concern, such as: radon, pesticides, and other sources of air pollution?

❐ Climate change can worsen indoor air quality. Severe weather events such as extreme temperatures, flooding, and storm severity bring increased humidity and mold growth, droughts, and wildfires.

Nearly every home (96 percent) has at least one indoor air quality problem. You can take steps to improve the air quality in your home by reducing or removing the sources and by proper ventilation with clean outdoor air. Additionally, research shows you can effectively supplement this by filtering the air and catching pollutants, allergens, and dust particles with air purifiers.
