Do air purifiers help with smell?

Do air purifiers help with smell?

Hospital-grade air purifiers like Rensair offer a lot of benefits by removing potentially harmful particulate matter from the air. Filtering and circulating cleaner air can help reduce allergies, prevent asthma flare-ups, and eliminate the potential for mold-related illness.

A HEPA air filter can also aid in removing lingering odors from a home. But before you make the purchase of a high-efficiency air filter, you should know that eliminating odors shouldn’t be your primary reason for doing so.

What causes smell?

According to the Agency for Toxic Substances and Disease Registry, there are several sources of environmental smells that may find their way into your home, including animals, household cleaning agents, garbage, or nearby industries like landfills and treatment plants and gardens that can enter through open windows or doors. These pollutants and many others can linger in the air within your home or stick to surfaces.

HEPA filters, like Rensair, remove a high percentage of odorous particulate matter, like dirt, dust, soot, and smoke, from the air. Odorous particulate matter from secondhand smoke, for example, is one that may stick to surfaces like walls, floors, and furniture, and won’t become airborne unless interacted with.


How efficiently does a HEPA filter remove smell?

Simply installing an air purifier, no matter how powerful, won’t necessarily rid a space of odor entirely. Similarly, while air purifiers can remove airborne mold particles from the air, odorous mold that is physically located on walls, floors, or other spaces will not necessarily be eradicated by the installment of an air filter.

Additionally, most odorous airborne particles are too small to be removed by even the most efficient air filters. In “What is a HEPA filter?”, it is noted that most HEPA filters can remove particulate matter that is 0.3 micrometers or larger. Unfortunately, many odors—that of food, pets, or houseplants, as examples—come from particles that are smaller than 0.3 micrometers.

But despite what you might be thinking, implementing a HEPA filter—after a thorough cleaning—can help eliminate lingering odors and can certainly help with odorous airborne particles, to some extent. The best method is to begin by eliminating the source of the odor as best you can. Rensair HEPA filters have been known to assist in the removal of lingering odors in addition to purifying air, leaving users with clean, breathable, and scent-free air.


Why do we want to remove bad smells?

Most smells that you’d like to eliminate with the help of a HEPA filter are unpleasant and unsettling. Not only is it disruptive to your lifestyle to come into contact with bad smells, but foul odors are generally associated with unsanitary living conditions and can even be signs of potentially harmful substances. Mold, for example, can have an unpleasant odor and can also be detrimental to one’s health if not removed, and secondhand smoke has been linked to health effects such as asthma flare-ups. Removing the source of these odors and supplementing that removal with an air purifier will ensure your home smells pleasant and will assure you the air you are breathing is clean.
