Need Stealthy Air Pump

I am in need of a very quiet air pump. Every bit of noise has been taken care of for a small DWC grow besides this. Anyone have any recommendations on an extremely quiet air pump?

petco 10 gallon or 13 gallon air pump. if you just set it down it has rubber pads on the bottom they make no noise if its not touching anything else.

tetratec air pumps are very silent i had to upgrade my pump to one of these because they are so much quieter, i had to sleep next to my cab with it running 24 hours a day so noise was an issue like yours

whatever pump you get should run pretty quietly if placed on a brick placed on carpet.

wrap the pump in a towel. works like a charm

the cheap budget airpumps are very loud
