NICREW Nano Silent Aquarium Air Pump Black, Aquarium Aerator with Accessories for Up to 10 Gallon Fish Tank, Super Quiet, 0.3 L/min, 1.5 Watts

very cheap and actually noisy and broke minutes after using it.

Too much requirements to use it. Make product not good for me. First 110v ac, second should be up of air output, need valve to stop water, not powerfull, noise is too much to put the aquarium in bedroom. Not returnable easily

Falling in love with the nicrew product. I got the filter assembly because I needed a small filter that didn't over power my 1 gallon and 3.5 gallon tanks and just fell in love. I needed a small air pump for my small air sponge and saw nicrew had this and you can put it on the tank. It is so easy to use and the size is perfect to keep out of the way. It functions perfectly and is super quiet that i forget it is there. Perfect air flow and the price is a perfect match for the quality. Will be ordering more nicrew product as long as they keep the quality and price.

Works great pretty quiet

I’m using this nano air pump in a compact 3-liter deep water culture (DWC) hydroponic setup, and it’s been exactly what I needed. It provides just the right amount of aeration to keep the nutrient solution oxygen-rich without creating too much turbulence for the roots. Despite its small size, it performs reliably—and best of all, it’s virtually silent. The piezoelectric ceramic plate design makes it much quieter than traditional air pumps. I have it running continuously, and I barely notice it’s on. Setup was quick and easy. The kit includes the pump, tubing, a check valve, an air stone, and a suction cup—everything you need to get started right out of the box. The suction cup holds well and keeps the pump neatly in place. For small-scale hydroponic systems like mine, this is a solid choice. Quiet, compact, and effective—exactly what I was looking for.

I'll say that I'm pleased about the pump and what I paid for it. Switched out the hose after 3 days because... Similarly to other reviewers, the translucent "film" that is on the hose has disintegrated and spread throughout the tank. Thankfully most of it ended in the filter or substrate and I don't think any fish ate it. Aside from that, the pump is actually very quiet and discrete. Hoping it will last. I'll be trying it with two air stones soon - we'll see if it pumps strong enough for that.

Very quiet and runs my box filter with flow to spare, great fit for little betta tanks. Suction cup attaches well to tank. Great value for the little powerhouse. Have had no issues with durability after a month of use. Runs non stop and is never warm to the touch.
