Review: Surprisingly Quiet and Works Great - This is easily the quietest aquarium air pump I’ve owned. It runs smoothly with very little noise, which was a pleasant surprise compared to others I’ve used in the past. It provides consistent airflow, was easy to set up, and has been running reliably without any issues. Build quality feels solid and it does exactly what it’s supposed to do. If you’re looking for a quiet, dependable air pump, this one delivers.
Review: Fluval A402 is the worse Air Pump - This is the worse air pump I have ever purchased. The first one I purchased started making this loud noise and I had to return it. This second one I have just stopped working and no longer pumping air in my air stone. It only lasted for 30 days. I am glad I kept my Top Fin air pump because I reconnected it and started working right away. Stay far away from this Fluval A402. It is not worth a broken penny.
