With covid cases rising in the U.S. and the increasing chances of another lockdown in several parts of the world, it’s important to revisit some facts and measures to minimize the risk of contracting Covid-19. The CDC recommends using multiple mitigation strategies such as washing your hands, social distancing, wearing masks and improving ventilation in your home. While you probably already know everything there is to know about social distancing and washing your hands, improving ventilation doesn’t seem to be advocated for as often. So let’s take a deep dive into the benefits of air purifiers and how they can help reduce the risk of Covid-19.

Improving ventilation indoors can reduce viral particle concentrations, which are much higher indoors than outdoors. By lowering the particle concentration, you are reducing the overall viral dose to occupants. While improving ventilation won’t eradicate your chances of contracting Covid-19, it will lower them significantly. HEPA filters are especially good at removing airborne particulate matter in your home, removing up to 99.7 percent! This includes other harmful particles such as pollutants, pet dander, and dust mites.

How they work

HEPA filters work by capturing particulate matter through multi-layered meshes made from fine fiberglass threads thinner than human hair. They can trap particles as small as 0.3 micrometers. Our Beurer Air Purifier LR210 comes equipped with an activated carbon filter and H13 HEPA filters and can run for up to 4320 hours. It even comes with a sleep mode so you can sleep well without distracting noise and 3 fan speed settings so the clean air can circulate around your room.


Aside from trapping harmful pollutants and viral particle concentration, HEPA filters also remove unpleasant odors around your home by trapping odor particles and absorbing the smell. Harmful chemicals such as gasoline and those found in common cleaning products often linger around your house, creating unpleasant odors. Lower levels of these chemicals, also known as volatile organic compounds (VOCs), lead to improvement in productivity and performance, according to NIH studies.

When it comes to improving ventilation in your home, a HEPA filter is one of the best options available, but other air purifiers will still bring benefits. Check out our line of air purifiers and humidifiers and prepare yourself for that clean, crispy air that awaits you.
