HI, I understand thae the filtrrs come with the unit. So what about replacement, where can I purchase them, and the price please. And how long to be replaced ( operations hours aprox.)
This depends on your usage, if there is too much smoke it will be replaced quickly. Sorry, we do not sell consumables, they need to be purchased locally.
A lot of smoke and dust can be effectively filtered out through the upgraded four layers of multi-effect filtration, namely: filter cotton protective layer/primary filter cotton/middle layer filter cotton/high-efficiency filter cotton.
