Review: Fixed the problem - My canister filter was making a noise every now and then you would hear the motor come on and it sounded bad and was loud. The filter continued to work, but that sound was bad and it would eventually ruin the canister filter itself. Also, when you go to put the new one in or go to clean out the water in the filter canister. Put some Vaseline on the o- ring to get a seal. The canister filter doesn't always seal right and can be aggravating. Vaseline will create the perfect seal. If it doesn't seal properly, you didn't add enough Vaseline
Review: Perfect replacement - I was cleaning my sunsun canister filter out. I had trouble pulling out the impeller due to the strong magnet and then the ceramic spindle broke. I was in a panic, thinking I’d have to buy a whole new canister filter. But I’m so glad to find this exact match to perfect fit! It saved me money! And easily just popped in. I didn’t notice any reduction in flow at all.

### ⭐⭐⭐⭐⭐ Nice and quiet

After a recent clean and replacing of some filter media, existing impeller had gotten annoyingly noisy. What a difference this new impeller made. Pump is now quieter than it's ever been.
