hygger Quiet <30dB Aquarium Air Pump, Adjustable Low Decibel Oxygen Fish Tank Pump 2 Air Outlets Ultra Silent Powerful Aerator Pump with Accessories Max 80GPH/160GPH/255GPH(5W, Up to 150Gallon)

Super quiet air pump, in my video review I compared it to the eheim 100 which is far less powerful yet way louder? The 100 at full power has this loud buzzing noise despite that power difference. Both have a slight noise at full power but the eheim is more noticable, similar to that of an air compressor for cars. At full power with the bubbles from your airstone, sponge/moving bed filters those would mask any buzzing present although the eheim sticks out there, I am running the eheim 100 in my bedroom and I can hear it across the room! I cannot hear the hygger air pump at all. What is included is also a great value so you get a powerful and quiet pump for around 20USD$ on sale you get the pump with two lines of airline tube, two airstones, and two check valves to stop your setup from getting flooded from a power outage. Eheim on the other hand only gives you the pump and a single air stone. While their air stones are better quality since they have a filter, the price is also like double or triple and the pump is actually louder. From someone who has been using eheim for years I am comfortably sitting on the hygger side now, their pumps are objectively quieter as shown in the video. Great pump at a great price.

Literally the quietest air pump we’ve ever owned, and my hearing is neuro-spicy-I’m extremely sensitive to sound. I’ll definitely purchase more as our aquariums expand. We have two of them (for 2 tanks) side by side and the only time I hear anything is if something gets leaned up against it. Move the object and I’m right back to suuuuper quiet again. Adjustable air flow allows for better control of oxygen levels. If it has any drawback, it’s that it would be nice if each port had its own air flow control. Bang for buck, it can’t be beat.

I like how sleek and quiet it is. If you turn it up to max it will make a slight hum but honestly the sound of the bubbles this bad boy makes is louder. Comes with extra accessories like 2 check valves but id recommend getting a different air stone if you want to be fancy

This is the best pump I’ve ever purchased. Super quiet, I can’t even hear it unless I get my ear right next to it. The bubbles make more noise than the pump. Adjustability is wonderful too. You have a lot more options with this bad boy. I’d like to get another one.

Super quiet and works great for my 2 tanks. I have a 5 and 10 gallon with different flow needs so some control valves would have been nice to have with the purchase.

Been using this air pump for 3 months now (I have 3 of them) so far they work great and very quiet!

So far so good! I love that it is adjustable, unlike the last one I had. It's super quiet and keeps a good flow!

Update 2: I pulled it a part for a third time. I bought a screw extractor set and I was able to get the stripped screw removed and the diaphragm replaced. I put it all back together and now it is running beautifully and silent. If it had ran this way from the unbox this would be an easy 5 star review. I am $65.00 in on this pump now and it is finally working well after much headache and extra money spent. Update: I received replacement diaphragms that I had to buy, I was able to get one replaced but the screw on the second one almost instantly stripped. I now have a horribly unbalanced single channel air pump that sounds like shaking marbles inside of a cup when it runs at full power. Cool. Still disappointed. I unboxed this after receiving it to get the cardboard recycled asap. I didn't get it installed until a week later. I immediately noticed that one of the ports had 0 air flow and the second was incredibly poor. Unfortunately without the box I doubt I could return it. I took it apart and noticed that both diaphragms were split open. I'm having to buy replacement parts before it's even seen any use. BEWARE that this could happen to you. Keep your box! I have a cheap tetra dual port pump from Walmart that's been running non stop since 2018 and still has amazing output. This has me regretting not getting another one of those. My hygger is now in pieces until I can get replacement parts.

I only gave it 1-star because I cannot give it zero stars. I can not believe the “response” that I had from this supplier when an aquarium air-pump failed with burden-out actuator and vibration-damaged internal wiring after just 5-weeks operation. I will not buy any Hygger product again, but worse than that, the supplier flatly refuses to enter into any reasonable correspondence when I attempted to report a failure. They simply ignore their obligations under the Consumer Rights Act 2015, where goods are supplied, a legal contract for the sale or supply of goods exists between the trader and the consumer. This means that the trader - not the manufacturer - is responsible for the goods that they supply.

Not a review that can speak to longevity, but I bought this to replace a similar unit that was simply too loud. This pump is very quiet and does its job, pushing air through two large 12" bars. Very satisfied with this product.

Running 6 small tanks with no issues. I placed the pump into the liner that came in the packaging and now the pump is completely quiet. Very happy!

The adjuster is finiky. I have different pumps that are quieter. It is not horrible just not as quiet as it claims.

Excellent aquarium air pump. Lots of pressure which is adjustable. Very quiet.
