Have you ever stepped into your car on a hot Summer’s day, turned on the ignition, reached for the air conditioning dial and (horror of horrors) been left devastated (and unnaturally sweaty) as it has done nothing at all? Or worse, blown hot air out which produces a rancid odour?

Given the ‘heatwave’ (well that’s what we are going to call it anyway) that has gripped the UK over the past few days, we thought we would think about those unfortunate people who have experienced this problem.

According to The Telegraph, it is estimated that half a million car air conditioning systems fail each year and that fixing these systems can cost an annual £220 million. That works out to £440 each on average!

Honest John advises that the two most common reasons for air conditioning failure to be “lack of gas (via leaks at the system seals) and component breakdown”. 

Although, before jumping to the conclusion of it being an air conditioning fault have you checked your Cabin Filter?

 What is a Cabin Filter and Why is it Important?

 Perhaps an inconspicuous part of a car’s anatomy, but the Cabin Filter fulfils an important role to the occupants of the vehicle. The Pollen Filter filters out contaminants from the heating, ventilation and air conditioning systems. It strips the air of impurities such as dirt or pollen and can make the car journey uncomfortable, particularly for passengers with allergies or respiratory problems.

Why Should I check my Cabin Filter?

 A dirty or clogged Cabin Filter can cause bacteria to grow in the ducting on the condensation build up through using the air conditioning unit. This will subsequently restrict the airflow into the cabin and produce a very unyielding smell, which some people have described as like ‘wet dog’ or ‘smelly socks’.

How can I Check my Cabin Filter?

 Many Cabin Filters are located under the bonnet, behind the Glove Compartment or under the dashboard. We would recommend reading your owner’s handbook to check where the Cabin Filter is stored in your vehicle. Changing a Cabin Filter is a simple enough job, and Unipart have helped to make this easier for you by including instructions/diagrams in every box – which is a unique benefit of buying Unipart Cabin Filters, you will not receive these with any other brand!

 How do I Know if my Cabin Filter Needs Changing?

The simple answer to this question is to check the Cabin Filter and see! If you see grime, residue, leaves or debris all over your Cabin Filter, then it is likely that it needs to be replaced. We would recommend that you check your owner’s handbook to see what the interval is for changing your Cabin Filter.
