Denso underlines health benefits of replacing the cabin air filter

According to the WHO, ambient air pollution accounts for an estimated 4.2 million deaths per year, linked to serious illnesses, such as stroke, heart disease, lung cancer and chronic respiratory diseases.

Heavy traffic remain a major source of pollution; therefore, it is imperative that their cabin air filters, which play a vital role in keeping contaminants out of the interior and allow motorists and their passengers to breathe clean and fresh air, deliver on their purpose.

Denso Aftermarket achieves this objective with two different filter types, both of which naturally provide original equipment performance.

Its particle cabin air filters comprise of a non-woven fabric that traps and holds fine pollutants, such as pollen, dust, bacteria, soot, lead, sulphates and exhaust fumes. Preventing these contaminants from entering the cabin ensures motorists and their passengers enjoy a safer and more pleasant in-car environment.

Denso Aftermarket’s combination cabin air filters, meanwhile, are made with a layer of activated charcoal, attached underneath the filter medium, which creates an effective ‘adsorption’ process that condenses gas on the surface. This stops unpleasant – even harmful – gases and smells entering the cabin.

The condition of the cabin filter runs parallel with the performance of the vehicle’s air conditioning system, and fitting a Denso Aftermarket cabin air filter will mean there is no drop in air pressure, which would potentially damage the vehicle’s heating, ventilation and air conditioning system (HVAC).

However, to stave off any threat of long-term damage to the HVAC system, it is imperative that technicians regularly change the cabin air filter. Denso Aftermarket recommends replacing the part every 6,000-9,000 miles (depending on vehicle type), once-a-year or as specified by the vehicle manufacturer (VM).

Technicians should pay particular attention to the particle filter medium to see if it is blocked or has lost any of its electrostatic charges. There may also be a strong build-up of dust or pressure drop, while an adsorption of noxious pollutants in the charcoal layer may lead to the pores being blocked or a decrease in the effectiveness of preventing odour from entering the cabin.

With the serious health consequences of being exposed to contaminants if the cabin air filter isn’t replaced within the correct intervals clear, Denso Assistant Manager, Aftermarket Network UK & IE, Mike Sadler, underlined the importance of fitting the right cabin air filter from a technical perspective: “The use of lower quality aftermarket versions, rather than an OE part, may pose a risk of compromising the vehicle’s HVAC system, which can often result in costly damage. An inferior quality product can also shorten the life of the vehicle’s interior heater blower, for example, therefore causing a completely unnecessary and easily avoidable aggravation to the owner.

“Using the correct, precisely matched replacement filter is the only way to ensure that such a highly-engineered and sensitive system can function at the high level of efficiency at which it is design to operate.

“Unfortunately, however, this practice is still sometimes overlooked in favour of installing a cheaper ‘generic’ alternative, but with air conditioning systems in particular, this is very much a false economy, similar to using a universal, rather than the specific formulation of oil for a compressor, for example.”

Denso Aftermarket’s products are all manufactured to the same standards, in the same facilities, as the OE components supplied to VMs.
