Way too loud, can hear it on the other side of the house. Putting a towel on it does nothing as even suspended it’s the same noise level, which seems to be coming from the motor or how the motor vibrates the casing, not how the casing vibrates on a surface. Maybe mine is defective because many reviews claim it’s quiet whereas only a few mention it being loud. Either way, I have this one plus Hygger’s 4w double-outlet block pump marketed for aquariums up to 120 gallons and that one is super quiet (can’t hear the pump itself from 10 feet away) unlike this one. Just spend the extra eight or so dollars to get that one instead.
Also I bought this for a 10-gallon quarantine tank and while it is adjustable, lowering airflow does little for the noise and still puts out a little more air than I’d like.
So while it’s technically good value, assuming mine isn’t defective then it’s only suitable in already noisy environments and/or places where you won’t mind the noise, and the same company makes significantly better pumps for just a little more money.
