Step-by-step instructions for removing the old filter
The process of removing the old element begins with emptying the passenger glove compartment. You need to open it and unscrew the screws that secure the opening limiter. Usually there are two of them: one at the top, the second at the bottom. Carefully unscrew them with a Phillips screwdriver and set them aside in a safe place.
After removing the fasteners, carefully pull the glove compartment down to remove the restrictor. You will now have access to the rear wall of the glove box. If you have a climate control system, behind this wall you will see a plastic filter cover secured with latches or screws.
Remove the cover of the filter body by snapping the locks or twisting the screws. Older elements can be heavily contaminated, so act carefully so as not to spread dust around the cabin. It is best to immediately substitute a box or a bag for recycling the old consumable.
โ๏ธ Removing the glove compartment
If you can't find the filter behind the glove compartment, check the space behind the ashtray. In some configurations, access is carried out by removing the center panel of the console. This is a more time-consuming process that requires the removal of decorative overlays.
- ๐ง Use a plastic card or spatula to remove decorative panels so as not to scratch the plastic.
- ๐ Examine the filter body for cracks or damage that could lead to depressurization.
- ๐งน Wipe the inner cavity of the body with a wet wipe, removing the accumulated dust and dirt.
Difficulties in removing the glove compartment

Installing a new filter and installation nuances
Installation of a new filter is a crucial stage where it is important to observe the direction of air flow. The body of the new element always has an arrow indicating the direction of the air flow (Air Flow). It should be directed downward or in a direction corresponding to the design of the duct of your model. Incorrect installation will reduce the efficiency of filtration and create excess resistance.
Carefully insert the filter into the housing, making sure it fits snugly on all sides. Make sure that the rubber seal is not twisted or protruded beyond the seat. If the seal is damaged, the filter will not be sealed and dust will bypass it.
Replace the housing cover and secure it with screws or latches. Reinstall the glove box limiter, tighten the screws and check that the box opens and closes smoothly. Don't forget to wipe your hands and remove any debris that may have formed during the work process.

| Body modification | Filter location | Access Features | Recommended replacement interval |
|---|---|---|---|
| Liftback (Tour) | Behind the glove compartment | Removing the drawer stop | 15,000 km or 1 year |

One of the most common mistakes is ignoring the presence of two filters in climate control systems. Many owners change only the top one, forgetting about the bottom, which reduces the overall cleaning efficiency. Also, do not allow the filter to skew during installation, as this will lead to air blowing past it.

FAQ: Answers to frequently asked questions from owners
How often do you need to change the cabin filter on an Octavia A5?
The recommended replacement interval is 15,000 kilometers or once a year, whichever comes first. In conditions of heavy dust or frequent city driving, it is better to reduce the interval to 10,000 km.
Is it possible to install a regular filter instead of a carbon filter?
Technically possible, but not recommended. A conventional filter only traps dust and lint, but does not block harmful gases and odors. The carbon filter provides better protection against exhaust gases and unpleasant odors, which is especially important in traffic jams.
What to do if the glove compartment cannot be removed?
Check if you forgot to unscrew the limiter. Sometimes screws can be hidden under decorative plugs. Also make sure you don't use excessive force, as the plastic may crack.
Should I change the filter if it looks clean?
Yes, even if the filter visually seems clean, its pores can be clogged with microparticles and bacteria. Contamination is not always visible to the naked eye, so compliance with replacement regulations is mandatory.
โ ๏ธ Attention: If the smell does not disappear after replacing the filter, the problem may lie in the air conditioner evaporator, which requires professional dry cleaning.
