Product description
Easy to Install: Remove the sponge, add water until it reaches the outlet, plug in and wait for smooth operation, then reinsert the sponge. (NOTE: Do not insert the sponge too early to avoid blocking pump outlet, slowing water intake, and causing noise)
2-Stage Filtration: Feature a porous bio sponge that traps debris, uneaten food, and fish waste to keep water crystal clear. It also provides ample surface area for beneficial elements to thrive, helping absorb and eliminate harmful substances
Compact but Efficient: Measuring just 3.53″ L x 3.56″ W x 4.27″ H, this aquarium filter fits perfectly in freshwater or saltwater tanks up to 5 gallons. It provides mechanical and biological filtration to keep your aquarium clean, stable, and healthy
Oxygen-Boosting Water Wheel: Built-in rotating water wheel greatly increases surface agitation, effectively boosting oxygen exchange to increase dissolved oxygen levels. This creates a more vibrant habitat that promotes lively, healthy aquatic pets
Quiet & Adjustable: With a water wheel to reduce motor noise, it runs silently under 30 dB to keep your tank calm and promote the well-being of fish. The handy rotatable knob lets you easily adjust the water flow to meet the needs of underwater life

Noisy
Seems to work okay but is really loud, I have taken it apart several times to try and solve the issue but the motor is noisy still.

Fails immediately. Do not buy
I’ve had this for 18 days. 18!!! It’s already failing… You get what you pay for .. unfortunately I got rid of the box. It is squealing. The spining bio filter never really spun. If I could give it 0 starts I would. Do not buy.

Great product, works awesome
This little hang on filter works great. I have it in my 2 gallon tank and its perfect for it. Its easy to set up and clean. It moves around the water just enough for some turbulence but not to much that its knocking everything all over the tank. I don’t have to clean it too often but when I do the parts are easy to figure out how to put back.

Quiet and Effective for Small Tanks- Just Needs Manual Priming
I’m using the Pawfly 3W Aquarium Filter in my 5 gallon shrimp tank, and overall, it’s been a solid choice. The tank is somewhat self-sufficient, but this filter helps keep the water moving and clear. One the best parts is that it’s not very noisy- Our tank is in the living room, and the filter runs quietly in the background. The main downside is that it’s not self priming. If you turn it off for tank cleaning, it can take a few minutes to get running again. And like the directions say, take the sponge out first, once going, place the sponge back. It usually helps to get it running.Still, for the price and performance, it’s great little filter for small tanks like mine.

Quiet compact tank filter
Nice little compact filter. Super easy to set up and runs very quiet. You do have to prime it to get it working, but itâs not hard to do. The bio wheel is a great feature. Itâs big enough for me to add my own filter media in it which is a huge plus. My other filters for my small tank donât allow this. The flow is good and not too strong for my beta tank and I am really happy with this one.
