 Very good valueSep 24, 2011
By Carlen Stillman
I bought a 5 gallon air pump for more than this, and that air pump failed to pump air through 2 2.5gal tanks. So, I went to the overkill side and purchased this. First, though, I want to address some of the other reviews.
NO air pump, I repeat, NO AIR PUMP IS SILENT. If a manufacturer tries to sell you a silent air pump, you need to step back and assess if their project development team has taken remedial physics. Vibrations create sound, which means no silent vibrating air pump diaphragms. According to classical physics, it is physically impossible for that to happen. However, through sound damping and clever material choice, you can make it so that it's close to silent. You'll never actually get there, but you can make it quiet enough to not be heard over the usual white noise of the home.
This air pump is the quietest I've ever gotten my hands on. I live in a building with a constant low level of background noise, and I have to concentrate to pick the pump's quiet hum out. It's well constructed, the rubber feet do a lot in the way of damping sound, and if you have it in a bedroom, wrapping it with a towel makes it practically inaudible. Otherwise, it's a very well built and well functioning pump for its price. You will never find anything as good quality as this and for as low a price as this; I can guarantee it from weeks of searching online.

Nice and quietMay 23, 2011
By JMyers
Pump is whisper quiet. Comes with an inline check valve to adjust the level of output. Works great. Does not come with any hose, or with any t- fitings, so these will need to be purchased seperately.

better than mostSep 21, 2010

This pump is better than several cheaper ones we've tried, though it does have a larger footprint. Rubber feet are excellent.

fairly quietJun 28, 2010
By James Prather
This air pump is fairly quiet with little "spurts" were it will get very loud, but this gets fixed by simply touching the thing... although i don't know why. it pumps a good amount of air into the tank, and i think the fish are very happy with it. I suggest buying this air pump for anyone who wants happy fish.

 NoisyMay 24, 2010
By AM-Review
This thing is far from 'quite'. Not sure how loud the other reviewers pump was, but this thing makes a racket in my opinion. And no, it doesn't seem broken at all. This is probably how all of them sound.
Not only does it emit a very low frequency 'buzz' that resonates all throughout my apartment (much louder than my fridge), but there is a high pitch buzzing noise as well. This thing is driving me crazy, I am probably going to have to buy/make some kind of sound dampening box or something to put this in because it's buzzing is one of the most annoying sounds I have ever heard in my life.
Using my SPL meter, this thing is running at about 70dB.
Aside from that it seems to run fine, gets a little warm though.
