Cold weather has us reaching for the moisturizer. But why does winter air dry us out so much? Indoor air quality in the winter can be filled with pollutants, and drier air can leave you more vulnerable to oxidative stress. Read more to find out how to combat winter skin woes.

Air purifiers can remove unhealthy particles and toxic gasses, which helps protect us from diseases made more likely by air pollution in addition to reducing allergy and asthma triggers. When choosing an air purifier it’s very important to have one that is sized to the space it’s used, and that it’s in a spot where you’re most likely to breathe the air it cleans.

Each indoor space is unique, with its own sources of pollution and rate of exchange with outside air. Pollutants can build up indoors so Outside air is usually cleaner than indoor air. A great way to stop pollutants from building up is to remove them with an air purifier that filters out toxic particles and gasses, but their total impact is never completely clear because air pollution is constantly coming back.

These days, it’s pretty easy for indoor air pollution to build up to levels that would trigger an air quality warning if they were found outside. Even something as simple as cooking dinner can pollute your home with harmful gasses and airborne particles that remain in the air long after you’ve finished eating.

Air purifiers are a great tool to cut down the presence of air pollution in your home. Not only can they work to minimize your exposure to airborne pollutants, but they may also help relieve allergy symptoms, reduce household dust, and even bust funky odors.

The tax-exempt dollars that go into a Flexible Spending Account, or FSA, can be used to buy FSA eligible air purifiers and the filters they need, as long as a doctor writes a letter of medical necessity.

Most people spend around a third of their lives in their bedrooms (assuming you get around eight hours of sleep a night, which is one-third of the day). So, it stands to reason that placing an air purifier near your bed can give you uninterrupted access to clean air for hours at a time.

Your home is a space that should allow you to control the influence of outdoor temperatures, precipitation, and pollution. However, sealing your home from the outdoors can also trap pollutants indoors, in some cases allowing air pollution to build up to unhealthy levels. A wide range of substances can affect the air quality in your home, including particulate matter, toxic gases, viruses and bacteria.

Air purifiers, on the surface, may seem deceptively simple — dirty air is drawn in through a vent and clean air is blown out. But the quality and technology of the mechanisms and filters inside these machines can make all the difference in determining just how effective they are at cleaning indoor air.
