SUNReplacement Impeller for SUNSUN Aquarium Canister Filter HW304A/HW304B Microsystems, Black, HW-304B Impeller

Nice product looks small but it’s fit properly and no sound

Not like photo , i feel is bad quality

My sunsun 404B was making a lot of noise. This completely solved The problem. works nice and quiet right now.

My Sun Sun 704 was soooo loud to the point I was going get rid of it. But I found this. Was hard to find for the 704 because it's was not in the description. Saw I review they said it fits so thank you.....

Je l'ai commandé pour remplacer celui d'origine sur mon SunSun HV304B. Mon filtreur, sortie de la boite, a la premiere utilisation faisait un bruit hors norme. Finalement avec le nouveau "impeller" j'ai le silence! L'original était trés bruyant, malgré qu'ils sont "identique" celui-ci ne fait aucun bruit de "cognement". Bref, satisfait a 100%. Filtreur et filtation impeccable.

I just purchased a new Sunsun HW-704B filter that seemed to have a noisy impeller. I wasn't sure if the impeller was the problem or if my filter media was just too dense. Overall, the 704B was working well, but it was not quieting down after one week. On a hunch I ordered this replacement impeller and it was an exact match. After installation the filter noise and vibration decreased about 50%. Now my 704B performs well and is also relatively quiet. I am keeping the original impeller as a backup spare.

We purchased it to replace our original one that started making big noise recently. Now, it works very well since we replaced it.
