Minimising the effects of hay fever with DENSO Cabin Air Filters

Hay fever can be a big problem for drivers, with as many as one in five suffering from symptoms as the annual season reaches its peak. In addition, when travelling, all a vehicle’s occupants are also exposed to other pollutants that can have a similar adverse effect on the eyes, nose and throat.

Fortunately however, there is highly effective, although often unappreciated, car part that can help alleviate the symptoms caused by hay fever and also reduce the impact of airborne pollutants, and that is the cabin air filter.

The cabin air filter is extremely effective at filtering out tiny particles such as pollen, which means that, providing the filter is not clogged, and the windows kept closed, it can minimise the airborne pollutants in the cabin to a level that most hay fever sufferers can comfortably tolerate.

Cabin air filters, such as those produced by DENSO, consist of a first filter medium that keeps out coarse particles, which is supported by a filter fleece that increases its dust retention capacity. Those with an active carbon layer also filter out bad-smelling odours and hazardous gases, such as ozone, smog and exhaust gases. Others even neutralise allergens and bacteria, odours and harmful gases, while the most effective media removes fine dust, including micro-particles with diameters smaller than 2.5 mm, which is just 0.005mm!

In addition to the health benefits for the occupants, DENSO cabin air filters also protect the vehicle’s heating, ventilation and air conditioning system by preventing airborne particles from entering it and sticking to its internal surfaces and clogging airways.

However, irrespective of its quality, over time the cabin air filter will become less effective, because it is the barrier that stops all the dirt that would normally come into the cabin and collects it. So, just like the bag in a vacuum cleaner needs to be regularly emptied and the filter cleaned, the cabin air filter will need to be replaced, ideally every year, but at the very least, in line with the vehicle’s service schedule.

DENSO’s cabin air filters have been developed to original equipment quality standards with advanced technologies, to ensure an easy fit design and long life efficiency. By filtering and trapping potentially irritating and hazardous particles before they enter the car’s cabin, they provide the occupants with a clean and temperate environment.
