Why were a mask if you don’t do this. These are not normal times for anyone and we change our engine air filter but never our cabin air filter. Let’s see how a cabin air filter looks like after just one year.

Will my car’s cabin air filter help reduce the spread of coronavirus?
It seems within the last 30 years or so, cabin air filters have become a regular part of your vehicle. Automakers tout their ability to filter out dust, particles, smells and more. But can they help to protect a vehicle’s occupants against the coronavirus (COVID-19)? We’ll take a look at that in a minute, but first, consider the lowly facemask.

You see people everywhere traveling while wearing filtration facemasks over their nose and mouths. It may be a bit off-putting, and those individuals think they are doing their part to prevent the spread of the coronavirus, but are they? That depends. If you are carrying the virus already, a mask may protect others from catching it from droplets that may spray from your mouth, according to the Centers for Disease Control (CDC). But it is not a total failsafe.

And that’s where your car’s cabin filtration system is similar to the mask.

Some car filtering systems consist of a HEPA filter, which is designed to purify, or at least filter, the air coming into the cabin of your vehicle. HEPA Filters in automobiles are a type of pleated air filter. It is an acronym for “high efficiency particulate air” filter. It is not a failsafe as particulates can enter when a door is opened or a window is lowered. Additionally, not every filter that says so is a true HEPA filter as the term has taken on a marketing life of its own.

Virus particulates often too small to catch
First of all, consider that the coronavirus particulate measures between .06 and .14 microns in diameter. Most HEPA filters in today’s modern vehicles can trap germs down to .3 microns, according to the Society of Automotive Engineers.

SAE’s publication, Automotive Industries, states “The goal of reliably filtering coronavirus from a vehicle cabin has myriad challenges. The efficiency and adsorption functions, the need for effective and safe anti-allergen additives and the form factor of the filter all must work as a system – one that’s comfortable for passengers using the vehicle’s air conditioning and that can be industrialized by manufacturers. There’s no silver bullet.”
