hygger Aquarium Air Pump,Adjustable Oxygen Pump，Silent Powerful Aerator Pump 2W/3W/4.5W/6W/ 1/2 Air Outlets Ultra for Up to 100 Gallon Tank

This air pump is impressively quiet and delivers a steady stream of bubbles, perfect for maintaining oxygen levels in my 20-gallon tank. The adjustable flow is a great feature, allowing me to fine-tune aeration for different setups. It’s compact, easy to install, and doesn’t vibrate much, which helps keep noise down. One tip: use a check valve to prevent backflow. Overall, a solid choice for anyone looking for a reliable, silent air pump.

I've bought air pumps before that were supposed to be quiet. Only to discover you'd have to be deaf to be ok with the noise. This air pump is running 2 filters on high no problems. All I hear is a low humming. I'm getting a new Betta. I wanted to have increased filtration but at slower speed. I'm completly happy with purchase.

Is still a bit noisy but is worlds better than most other pumps- plus it has the air control built in which also helps cut down on noise

Perfect pump I have it running a sponge filter in my 75 gal aquarium and it’s perfect. Nice and quiet. I like that I can adjust the air flow. I think it’s a great pump for the money and my husband is ordering one for his tank now too.

Probably the quietest pump I’ve owned! I’ve been using it for a while now in my 20 gallon long for my betta fish. High quality for the price, easy to set up and adjust, and would definitely recommend!

I'm really disappointed in hygger for this product. I own two other hygger products and did a comparison: - this different air pump (5 Watts) hygger Small Quietest Aquarium Air Pump, Adjustable Oxygen Pump 2 Air Outlets Ultra Silent Powerful Aerator Pump 160GPH 5W (https://www.amazon.com/gp/product/B087QZ1F52/ref=ox_sc_act_title_1?smid=AVCC5D32ELY5X&th=1) - this sponge filter (dual M) hygger Aquarium Double Sponge Filter for Fresh Water and Salt-Water Fish Tank (M) (https://www.amazon.com/gp/product/B07RKT6QPV/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1) I plugged in this air pump (2W) and was met with huge vibration noises. this pump was to replace a dud for my grandma's 5 gallon tank but this is way too strong and even louder than my 5 Watt air pump at its max output. My grandma would hate this noise, you can't even try to muffle it with towels. You can still hear it across a room. You can see in the video that the 2W air pump slides on the floor when on and compare how loud it is to the different 5W air pump vibrations in the 3rd video. The second video is me putting in the 2W into my M sponge filter and its relatively strong in my 20 gallon long. The third video is demonstrating how much more quiet the 5W is even at its max.

I know all diaphragm pumps produce noise, it's an inescapable fact of the fishkeeping life. That being said, I've been pretty happy with a number of Hygger products and figured it was worth giving them the benefit of the doubt here. I appear to have made an incorrect decision. The pump puts out a great amount of air, I love that it is adjustable. It does it's job well, it's just anything but "Silent" as the listing claims. It's probably one of the louder pumps I've used and seems to be far louder for the output of air compared to the tetra whisper series. I will be able to find a use for this product, but it will not be in my office any longer. I am going insane from the buzz.

I paired the 2W air pump with a 5cm hygger air stone. Works great together!

I made a YouTube video reviewing this product because it was so noisy and terrible, and before, I’d heard only praise about how good hygger were, but this is not good at all. You can see exactly how noisy it is from the video.

I bought this after reading the reviews about how quiet it was, and to be fair, it actually was. It’s not quiet anymore. The gentle hum lasted about 2.5 months but now I’m looking for something better.

Controller is not working

The item said it was adjustable. When it arrived it was not, not all the pumps are adjustable. Second the plug was a US plug and 110 volts. I could not use it so cannot comment on its performance. I have other Hygger pumps which are very good. This one i cannot comment on apart from what i said above.

La pompe fonctionne bien mais tous les autres articles montrés sur la photo (pierre, tuyau, filtre, jonctions) sont manquants. J'ajusterai mon évaluation à 5 étoiles si je les reçoit . . .
