Frequently asked questions about the cabin filter Nissan Liberty

Is it possible to wash or clean the old cabin filter instead of replacing it?

No, it's ineffective. Paper filters are destroyed when wet, and carbon filters lose their absorbent properties. The only exception is blowing with compressed air (for example, at a service station) to temporarily remove large dust, but this will extend the life of the filter by a maximum of 2–3 thousand km.

Which filter is better: carbon or regular?

Depends on operating conditions:

• 🏙️ Coal mandatory for the city (retains exhaust gases and odors).
• 🌳 Regular suitable for rural areas (cheaper, but copes worse with gases).

A carbon filter lasts a little less (10–12 thousand km versus 15 thousand km for a paper filter), but purifies the air 30–40% more efficiently.

What should I do if there is still a smell in the cabin after replacing the filter?

Causes and solutions:

• 🦠 Mold in air ducts: treat with a cleaner (for example, Step Up Air Conditioner Cleaner).
• 🚗 Clogged air conditioner drain: clean the tube under the car (it comes out near the gas pedal).
• 🔥 Burnt smell: Check the fan fuse (F30, 30A).
