Cabin air filters – the most important filter in the car!

Hi all

Today, we’re going to be taking a look at cabin fiters, and the role they play in filtering out all of those nasty particles found on the roads these days. We use Mahle for the majority of our filters, and for good reason – they offer OEM quality products that are designed to reliably fit a huge range of vehicles, at great prices.

According to Mahle, the most important filter in your car is the cabin air filter. Their reasoning for this is that the air we breathe is full of harmful gases and particles such as particulate matter or soot. A Mahle air filter with activated carbon keeps up to 99.5% of these pollutants out of the vehicle interior – and also absorbs unpleasant smells.

As you can imagine, the activated carbon layer plays a major role, and the reason for this is that it absorbs the harmful gases. Some of which include:

  • Hydrocarbons
  • Hydrogen sulphide
  • Sulphur oxide
  • Nitrogen oxide

There is also a considerable amount of pollen, soot and other particles in the air at all times. This leads to a significant relief, especially those with respiratory diseases and allergy sufferers. The different types of contamination can be tracked throughout the seasons: In spring, there is lots of pollen and grass seeds in the air, this coarse contamination can lead to blockage of the pleated surface. In summer, you have soot and fine particles to contend with. Autumn brings higher air humidity which means more dust and microparticles, and finally, by the time you get to winter, the filter is clogged and due for replacement.

This special activated carbon layer is sandwiched between two layers of fleece. A heat process is used to fuse the filter layers, meaning that no solvent is used – solvents containing glues are harmful to the environment, as well as potentially damaging to the health of those involved in the manufacture process, and the end user. That’s you by the way.

Mahle are perfectionists. Their view is that perfect quality is crucial for a high filter performance. Understandable when an air volume of up to 100,000 litres is blown into the vehicle interior in just one hour of driving. If the cabin air filter fails or when it becomes clogged, the pollutant concentration in the interior of the vehicle can increase to six times that of the outside air – this means that you start breathing in all those nasty things that a cabin air filter is supposed to protect you from. Another negative effect of a logged cabin air filter is the accumulation of fungi and bacteria over time. This leads to bad smells and harmful emissions in the vehicle interior.

So, how do you prevent all of these nasty particles filling up your vehicle? It’s simple really. Mahle and Opie Oils recommend changing the cabin air filter every 20,000km, or once a year, which ever comes first. This way, you can rest assured that you will have reliable filtering of your vehicles interior, and peace of mind that you are stopping pollutants in their tracks.
