Superfish Air-Pad Silencer

Cut the hum of my air pump by more than half after wrapping it in this foam casing. It fit my older model pump just fine, though I had to trim a corner for the airline tubing.

Slapped this foam pad onto my air pump and the annoying vibration noise dropped by at least half. The foam itself is thick enough to actually absorb the sound, not just muffle it slightly.

The bubble pump hum was driving me nuts at night, and sliding it into this foam case cut it down to a soft purr. It's made for my air pump model so the fit is snug, and I can still reach the dial without pulling it out. Cheap fix for a big annoyance.
