May I have further information about dust proof design of DX808ST and DX825ST?

04-07-2020

DX808ST/DX825ST is equipped with 20mm single-layer dust filter, which is able to avoid big particles entering up to 90% , greatly increasing protection in especially dusty environments. For added peace of mind, DX808ST/DX825ST also possess built-in Filter Timers that can remind users to replace filters. The built-in detecting mechanism will also remind users of resetting timer once filter is replaced.
