Washing out a few things

[GreenhouseEffect]

It can really make a big difference with noise, to! Mine got much quieter after I cleaned the pre-filter.

It’s made of flannel type( at least mine is) of material that goes around the filter to prevent large particles and moisture from clogging the filter,thus prolonging the filters life, as well as the fan
The only problem is,as it catches the partials it slows down the intake of air and must be cleaned regularly for peek performance lol

I think It’s the carbon filter filter haha the piece of sponge/fielter that goes around the carbon filter
