May I have further information about the dust proof design?

04-07-2020

This model is equipped with a 20mm single-layer dust filter, which keeps up to 90% of large particles out, thus greatly increasing protection in especially dusty environments. For added peace of mind, this model also possesses built-in filter timers that remind users to replace filters. The built-in detection mechanism also reminds users to reset the timer once a filter is replaced.
