Spring time is hay fever time, so as we head further in to the season, RAC is advising motorists to check their car pollen filters to reduce the effects of spring time allergies.

A recent WA study has found that hay fever is on the rise in Australia. The research, undertaken by Curtin University and the University of WA, has found that the Australian environment may be causing genetic changes and making people more susceptible to allergies such as hay fever.

RAC Patrol and former auto services technician, Luke Brown, says that given this rise in hay fever prevalence, it is a good time of year to check your car’s air filter.

“Air filters are designed to filter the air that you and your passengers are breathing through the heating and air conditioning vents,” Mr Brown said.

“They clean the air coming in to your vehicle, remove allergens and help trap airborne particles like pollen, dust and bacteria before they enter your vehicle.

“These are a vital element if you or your passengers suffer from hay fever, particularly parents who have their kids in the car often.

“A dirty or clogged air filter can cause contaminants to become so concentrated that passengers actually begin to breathe in the particles the filter is aimed at trapping.

“You need to check your owner’s manual to see if your particular vehicle is fitted with a cabin air filter. Your owner’s manual will also tell you where to find it, as the location of the filter will vary from vehicle to vehicle.

“Once you locate it, a simple visual inspection is a great way to check it. If you can remove it, do so and give it a good look over. Check between the ribs of the filter for dirt or other debris, and give it a clean out.

“The lifespan of an air filter will also differ from vehicle to vehicle. As a general rule, most air filters need replacing every 15,000 kilometres.

“If yours looks like it needs replacing, get a new one next time you take your vehicle for a service.”
