My kitchen stove hood fan needs a new carbon filter as the current one lookes pretty caked with grease from the previous owners of the place. It turns out the manufacturers filters cost €150 which I find a bit excessive. Filters seem to be the printer ink of the kitchen.
So I’m thinking either if it is possible to clean out the current one, or reuse the casing and refill it with some bulk carbon filter material, if there is such to be found.
I have no idea, I’ve never done anything of this sort before.
Experiences, ideas, suggestions much appreciated.
Edit: There is a metal mesh under that is washable, but also an internal filter, as the hood is recirculating the air back into the kitchen. My apartment building does not allow kitchen fan exhaust into the ventilation system.
@AdminWorker Thanks. While disassembling I realized it doesn’t seem to leak grease through as I mistakenly thought first, but now I think the casing leaks tiny amounts of unfiltered air that builds up a layer of grease over the years. So I used kitchen spray and paper to gently clean the clogged entry surface area of the filter. It seems to have good suction power, we’ll see if the coal still works.
Otherwise, I’ve found active coal pellets for air purification use on amazon and figure it should be possible to cut the felt on entry side open, replace coal with new and glue on some new felt.
I doubt it’s any particular high end coal in these filters and that the €150 price is because of $2 proprietary plastic frame so they can.
