— an indicator that shows the need to clean or replace the filter. It is usually installed on expensive electronically controlled models. This function is especially desirable for models with charcoal filters: after the expiration of the service life, such a filter begins to release harmful substances instead of absorbing them, and it is important to replace them on time.| filter indicator | clear | Save List |
