How to replace cabin filter?

It is not necessary to go to a service station to install a new car cabin filter. The procedure is rather simple. First, you should identify component location which can be behind the glove box, under the dashboard or under the bonnet. You can find it in the car manual. Then common algorithm includes the following actions:

1. Remove the filter cap after unscrewing fasteners.
2. Press on the filter edges and remove it. Install a new component according to markings on its housing.
3. Close the filter cap, fasten it.

Replace the cabin filter at the beginning of spring and autumn.
