NICREWUFO Aquarium Air Pump, Ultra Silent Air Aerator Pump for Fish Tank, Oxygen Pump with Accessories Included

This is a really useful piece of kit, and does the job perfectly. Personally I don't feel that the product is too loud, and have it on constantly in the living room with minimal disruption. Compared to some others on Amazon price-wise, I wouldn't look elsewhere for an equivalent, as this does everything that I need it to.The only reason I give this 4 stars and not 5 is due to the fact that as others have mentioned, I have found the tubing to periodically "slip" out from the connection, or from the unit due to air pressure. It's a minor inconvenience, and doesn't deter this from being an excellent product.

The pump really is silent, I have it in my room and can sleep with it turned on (it can still be heard though so if you are a light sleeper or can be disturbed by a constant buzzing noise). 10/10! Great quality for the price it costs.

I tried a few pumps from Amazon which claimed to be silent - they weren't, so they all went back.This one is as near to silent as I've ever got, so I recommend it.

A bit noisier thank I thought it would be, and the instructions were not great but I got there and it's doing its job

Really happy with this pump. Used in a 105l tetra aquarium. Enough power to pass bubbles through 20 inches of bubble bars creating a lovely wall of bubbles that my fish absolutely love swimming through. Almost no sound apart from therapeutic bubbles popping on the surface. Would recommend :)
