It’s that time of year again
As winter approaches in the northern hemisphere, those who suffer from allergies breathe a sigh of relief. For asthmatics, however, the cold air brings a number of challenges. But there are several reasons why all car owners should change their cabin air filters at the start of the winter season.
as well as fine dust there is also a high risk for bioburden to the passengers due plenty of organic material such as pollen, spores, and small plant matter. These not only reduce cabin air filter performance; they can also be a breeding ground for bacteria and spores. Even with microbiologically inactive filters such as those in the micronAir proTect line, humid winter air can cause the deposits themselves to provide the basis for bacterial growth if they are not replaced regularly. The result is increased ingress of potentially pathogenic particles and the risk for unpleasant smell due to fresh air passing the contaminated loaded filter.
This is precisely what we need to avoid in winter. At this time of year our immune system is already under a lot of strain due to the damp, cold air, and more frequent contact with viruses and bacteria. The additional risk of respiratory problems, colds, etc. due to old cabin air filters should be avoided.
Cloudy with a chance of particles
Cities in particular also have to contend with winter smog during the cold season. When a stable thermal inversion develops and a layer of warm air forms over cold air, the latter can no longer escape upwards as it usually does. The combination of this phenomenon with high humidity and emissions from traffic, industry, and residential heating results in persistent smog.
This smog can last for days and can accumulate pollutants such as soot, road salt dust, sulfur dioxide, and nitrogen oxides. In such situations, a high-performance filter is required for healthy air inside the car.
Effective protection from fogged windows
New filters also effectively protect against windows misting up. Especially in winter, when the window panes are cold, moisture in the air condenses easily and forms an opaque layer. This impairs visibility and consequently the safety of the occupants. Heating the cabin air promotes clear vision, as it can then absorb more moisture again. In addition, air conditioning systems equipped with new cabin air filters help to remove moisture from the air — and thus prevent fogged windows from the very beginning. There are many reasons you should change not only your tires but also your cabin air filters at the start of the winter season. One of them is to give yourself the best protection against pathogens and pollutants.
