As the weather turns brighter and the flowers start to bloom, many might be looking forward to some warmer days.

But for hayfever sufferers, these early signs mark the start of a dreaded season of stuffy noses, coughs and sneezes.

And while you might think the filtered air inside a car could offer some welcome relief from pollen, it could actually be making things worse.

Speaking exclusively to Sun Motors, James explained: "Something I do on my own cars and I recommend is...the pollen filter.

"This a filter that filters the air coming into the car from outside.

"In my experience over the winter these get damp and smelly and they have all the pollen from the spring and summer the last year.

"It can create nasty smells and damp smells inside your car."

The effect of this is that, when using your air conditioning, all the air being sucked into the vehicle through its intake passes through a layer of damp and musty pollen.

Not only can that cause mouldy odours, it also increases the amount of pollen being swept into the cabin, potentially worsening hayfever.

Thankfully, pollen filters are easy to check and to fix.

Often you won't even need any tools as the filter is commonly located behind the passenger-side glovebox and can be pulled out by hand.

Replacements are available online for as little as a fiver and you can just pop the new one in once the old one is removed.

It comes after drivers rushed to buy a £1 Amazon item that completely transformed their cars.
