Aquarium Filter Replacement Impeller HW304A/HW304B for Aquarium Canister Filter

It doesn't work, the product isn't the correct size for the Aqueon 400 filter, and it says it fits the SunSun which is the same size, that's a lie, don't throw your money away, now that I've opened it I can't return it anymore.

The water is moving through the filter smoothly, and my aquarium water has never looked clearer. ✅ Quiet Operation: The impeller runs super quietly, which is a huge plus. My old impeller made a noticeable noise, but this one operates almost silently, which makes the whole filtration system a lot more peaceful and less disruptive in my living space. ✅ Durable & Sturdy: The quality of the impeller feels solid. It’s made from high-quality materials and looks like it’s built to last. It seems much more durable than some of the original parts I’ve used in the past. ✅ Easy to Clean: The impeller is easy to clean and maintain, which makes it more convenient to keep my filter running at peak performance. It’s not a hassle to remove and clean, which is a relief. ✅ Great Value: For the price, this replacement impeller is an excellent deal.

Very good

My original impeller broke after almost 3 years. This replacement was a perfect fit and returned the unit to proper function. Pretty cheap and easy fix!

Was noisy at first! Extremely! But this replacement did the trick!
