NO hum CAN BE accomplished. Extremely low hum sound especially compared to my other air pump and returning model advertised as low noise (both air outlets must be used to be quiet). I totally reduced the extremely low hum to NO hum by placing the box included packaging foamy material under the air pump and placing about 3lb (1.4kg) weight on top of the unit; this got rid of any left over vibrations. I am checking for any heat where the foamy material touches the bottom of the air pump but none so far; I am very careful of the added foamy material because heat can reduce the life of the unit. The unit is sitting on the floor as shown in photo and will go under the furniture out of sight.The air flow is great as can be seen from one of the photos running at maximum into the 9 gal (34 liter) tank; in reality I see more air bubbles than the photo. The air control can easily keep the air flow at 0% to 100% and anywhere in between very easily; my other existing and another air pump I am returning are much harder in control. I am keeping the air flow at around half or less.There are two air outlets but if you only are going to use one, then either connect both into one with a T or Y valve connector, or block one of them. I am not sure if blocking one of them damages the unit so I have two output air pipes connected by a T valve connector into one pipe. Not using both output air outlets causes this unit to be as noisy as the competitors quiet air pumps like the one I am returning.In conclusion the price is a little high but for someone who can't stand the air pump hum, THIS IS AMAZING :-) I can actually sit on the couch look out the window and the fish tank and relax without any hum!!!The packaging of the unit is higher quality along the lines of quality computer products In comparison tosome of the other aquarium accessories. I guessing my unit quality is the same quality as all the other shipped units.I hope you found this helpful.

I’m very impressed with this little powerhouse. It feeds 4 aquariums, one of which is a 150 gallon tall, and still has lots of power. Due to reviews leaving negative comments about the noise, I was worried. Do not worry! It is super quiet on my laminate floor. The only little tweak I had was the adjustable knob. During the first couple weeks the air power increased slightly, so I had to adjust it back down. I suspect the problem was that I didn’t have enough outlets hooked up yet. I only had 2 small tanks on it. It stays steady now! It’s perfect for my application.UPDATE: After a couple months the pump failed but Hygger was quick to help fix the issue. I now have 3 of these nice pumps.

So far the pump is working as expected. It is quieter than I expected. Using it for culture projects, zooplankton and phytoplankton. Several large cultures going no proble. I was buying it again I would get the 10w for eve greater capacity. Can't go wrong with these pumps....

Just purchased this Hygger HG-981-10W adjustable air pump , fits perfectly in lower sump pump cabinet, but most of all impressively quite quiet, comparing it to my previous Tetra Whisper AP300 air pump which had one of two air outlets give way, as pictured I had purchased a repair parts kit which by the way had clear instructions and I had previously been successful in getting air flow back with the replacement parts, but this time the pump did not work after replacing. This was my second pump from Tetra in as many years and finally frustrated and decided to give Hygger a try as other Hygger products I’ve purchased in the past have not given me any issues, I was rewarded with a quiet, foot friendly (size) and adjustable air flow I did not get from the Tetra Whisper AP300 which works quite well, this has been a perfect alternative, albeit it’s longevity, which I will update in the future on its progress! I hope this pump lasts long enough to surpass my last one, so far it’s neck and neck out the box, longevity will prove the winner here, for now I will recommend, size, features, 2 outlets adjustable air flow, quiet, and priced lower than the Whisper AP300

Actually quiet. I've ordered 2 others that were very loud and this one by hygger is quiet and puts out enough air. I have mine on the lowest setting.

This is SO quite, you honestly won't even know it's on, except for the blue power light! It is THAT quiet! However, that DOESN'T mean you're sacrificing POWER! It's driving 3-4" & 1-8" bubblestone discs like I've never seen! 100% recommended! (I just hope it lasts!)
