The new shape of silence. The Whisper Air patented dome shape and sound dampening chambers minimize turbulence and produce a smooth quiet stream of air. Wide footprint; rubber feet and suspended pump motor eliminate sound producing vibrations. Thick walls insulate motor noise. Powerful diaphragms provide ample airflow for deep water applications. The versatile pump can be used for several applications including powering undergravel and sponge filters; airstones; and air-driven ornaments. The Whisper 20 model has one outlet and is rated for aquariums up to 20 gallons. Using an air pump adds dissolved oxygen to your water; improving the overall health of your aquarium.

This air pump gets the job done! This air pump is small and you could hide it anywhere near your tank. The only thing I don't like about this though, is that it makes a loud vibration noise when it is on. Other than that, it's very useful.

I have multiple fish tanks and this is my favorite air pump. It truly is whisper quiet. When you have it sitting on a table it makes just the faintest humming noise. I've owned about 3 of them for a couple of years now and they're still working as good as the day I got them.

This air pump is great, I have it for two years and continues to work as if it were day one ... now the only problem is that if much sticks to the glass emits a somewhat higher vibrations

These work great right off the bat, but I've never had one last more than a year.
