Silent air pumps?

[WhistlingBadger]

Happy weekend, kids. I'm looking for a couple little air pumps to run sponge filters, one for my invert tank and one for the Badgerling's betta tank. These are both in rooms where people sleep, so I don't want a buzzy pump. And in my experience, they're all buzzy pumps. Any suggestions?

Adjustable flow, or constant?

This one. It's so quiet you can't even tell it's running.

Are tanks close together. If yes, you could use this one as I found it quieter than other airpumps have tried. It’s adjustable

Tetra Whisper air pumps are moderately quite.

I have these running in all my tanks. They are great! And you can run them on a USB battery if you lose power.

Happy day...my old big Whisper has finally gave its last breath and shuffled off this mortal coil. So old and noisy it became that I put it into a small cooler to muffle the sound, but time just ran out. I came across https://fishlab.com/aquarium-air-pump/ and what I liked about this was that he came up with a bit of a test about the actual amount of air being pumped at different depths. I think you will appreciate his DIY testing and decibel rating methodology. After reading it, I am sticking with the Whisper the AP150 for my 125g. I did like the bit about 2 outputs being less forceful than 1, and I use a gang valve, anyway.

I was so wrapped up in me I forgot to talk about you...how millennial of me. You can try the small box trick. Take a small cardboard box, cut out a bit of styrofoam to the dimensions of the box, glue on some flame-retardant sheet (https://tinyurl.com/y39anye8 and Home Depot sells stuff too), cut one hole for the airhose to come out, and cut two smaller vent holes. I placed mine upside down so the intake was facing the top. I'm using a cooler, but when I had the larger bedroom tank, I used a shoebox.
