FAQ: Frequently asked questions about replacing the cabin filter on a Nissan Murano Z51

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

No, it's ineffective. Conventional filters lose their structure after washing and do not restore their filtering properties. Carbon filters should not be wetted at all - the carbon loses its adsorbing properties. The only temporary option is to blow out the filter with compressed air, but this will extend its life by a maximum of 1–2 thousand km.

What to do if the new filter does not fit into the grooves?

Most likely, you bought the wrong size filter. Check the part number or measure the old filter with a ruler. Also make sure that the filter is inserted the correct way (in the direction of the arrows). If the problem persists, try bending the filter frame slightly (some analogues come with hard edges).

How often do you need to change the filter when driving around Moscow?

In a metropolis with a high level of air pollution (especially in traffic jams), it is recommended to change the carbon filter every 8–10 thousand km, normal - every 6–8 thousand. Also pay attention to the appearance of the filter: if it is blackened or a layer of oily dirt is visible on it, it needs to be replaced unscheduled.

Is it possible to install a HEPA filter instead of a standard one?

Theoretically yes, but it is impractical. HEPA filters have a very high density, which creates excessive load on the fan Murano Z51. In addition, they do not allow enough air to flow through to effectively heat/cool the interior. It's better to stick to the original specifications.

Why did a burning smell appear after replacing the filter?

This can be caused by two reasons:

1. Debris (for example, leaves) has entered the ventilation system and burns on the heater core.
2. The new filter is of poor quality - some cheap analogues emit a chemical odor when heated. In this case, the filter must be replaced with an original or a proven analogue.

Check the filter housing for foreign objects and, if necessary, contact a service station to clean the air ducts.
