Ultra-Quiet Mini Aquarium Air Pump

Quick received. amazing pump, super quiet!!! works good so far. thanks!

It works great, but you can hear it quite a bit in the living room. My old compressor, bought in Slovakia, was quieter; this one is quite audible. I'll see in the future whether I can get rid of it.

I bought two devices.

One of the air compressors is defective. When switched on, sparks can be heard at the electrical contacts inside the device, and it operates very loudly. The plug of the device does not comply with the European standard, and the adapter included in the package is dangerous for children if they pull it out of the socket.

The other device works, but it is not silent as its operation can be clearly heard. It operates a bit quieter than my older, larger JBL compressor device.

👍 Everything works perfectly! I expected it to be much louder; I have the aquarium in my bedroom, and it was without this device for two years. Now I have more fish, so I decided to add oxygen to them, but I think I'll still turn it off at night, although we'll see. The sound is so gentle that you can easily fall asleep to it 😁

The pump is very loud compared to my piezo-ceramic pump at the same output level. Compared to my small and cheaper diaphragm pump, it is just as loud for the same performance. It vibrates as strongly as my diaphragm pump. In doing so, it often falls off the disk that has been cleaned with alcohol.
I can't use the pump like this; it's too loud. The performance is good.
