Cleaning the air filter and housing
This is the part of the projector that gets dirty the most. It is not surprising, because the filter collects all the dust and prevents it from getting inside the projector. Cleaning or replacing this part of the projector is the first thing you should do to avoid overheating the equipment. According to the advice of experts, the air filter should be cleaned every 3-4 months, removing accumulations of dust from it.

The cleaning steps are quite simple:
- Remove the ventilation grille and take out the filter from the special compartment.

- Carefully remove the remaining dust with a brush or vacuum cleaner.
- Put the filter back in the compartment and replace the ventilation grille
In some cases, it may be necessary to replace the filter. For example, if there is no way to completely clean the contaminants or damage the filter. Do not continue to use a flawed air filter.
