Hi so recently bought hyper phresh fan 8” expecting it to be quiet which impo it’s not that good so now I’m looking at having to buy the stealth version. But the weird thing is the noise sounds louder when I stand at different positions in the house sometimes it’s quieter when I’m closer to it. I also think that it could be air movement causing the noise. I have insulated ducting and I even bought one of their acoustic trap thing. Which didn’t help. Ok enough waffle if I buy a bigger scrubber carbon filter will this make any difference to noise. I’m thinking that it won’t pull the air through it as aggressively if that makes sense the room right above is really noisey and there is no way to insulate or dampen the room it’s in or the one above.
