Cabin air filters are used to filter particulates from the air entering your Audi passenger cabin to supply a continuous supply of clean breathable air. Some cabin filters are coated in activated charcoal and are capable of preventing noxious gasses and odors from entering the passenger cabin.

Clogged cabin air filters restrict the amount of fresh air entering the passenger cabin, allowing air to remain stagnant. Furthermore, it can cause a strain on the climate control blower motor that draws air into the passenger cabin, leading to premature failure to the blower motor and regulator.

Signs of a Clogged Audi Cabin Air Filter
A musty smell in your Audi is a sign the cabin filter is clogged and needs to be replaced to allow fresh air to enter your passenger cabin.

Replacing Your Audi Cabin Air Filter
Audi cabin air filters should be replaced every year, regardless of mileage to ensure clean, fresh air is always allowed to enter your passenger cabin. In particularly arid climates, it is recommended to replace your cabin air filter as often as every six months due to the high levels of dirt and dust in the air.

Cabin air filters are often located under the dash and can be replaced in as quickly as 10 minutes by removing the cabin air filter access cover or glove box. Some vehicles have cabin air filters under the hood where fresh air enters the climate control ducts or have multiple filters in multiple locations to filter air entering and circulating throughout the passenger cabin.
