It is very quiet. All I hear is a low hum when I am next to it and it is running. Remember, it is under water when it is running.

it was "whisper quiet" when i first bought it several years ago...over time it has gotten noticeably louder when it engages and when it shuts off, you will hear it from the first floor. i recommend this pump---it hasn't failed me yet!

Yes, it is loud. I was warned by one the reviews before buying it, but bought it anyway. I am happy with the machine overall, but the noise has got the biggest downside.

It's quite loud. If you are looking for a quiet model this may not be for you.

Really really low. It's also pretty quiet once the pump breaks in. I stopped using mine though cause my cats kept getting food in it and I was cleaning it constantly because if that.

No. It's probably no louder than running water into a 5 gallon bucket with a water hose.

The pump has rubber bushings to reduce vibration and noise, but I don't think the pump itself is that much quieter than other pumps.

Im not sure..I brought for my boyfriend for his work van. The pump works. He did say pump is a lil noisy.

It is no louder than other filters. The main noises are the bubbles and the pump. If your pump is quiet the filter will be quiet. I keep mine in my bedroom and the noise does not bother me.

Not loud at all. The machine is not a real great air filtering wonder. Air volume is low. Fan needs higher speed. I wouldn't buy it again.

The pump is not that loud. Mine is in the garage, so the sound is not an issue for us. It does make a clicking sound every few seconds while it is refilling the tank after you use water and also while it fills the tank. Otherwise, it does not make noise unless it is in use. Hope that helps!

You will hear a small bubbling noise from the filter, however, the air pump is usually just as loud. So all-in-all, I would say, not very loud.

It has a different sound. Instead of a low freq. pump noise, it has a high frequency motor noise. So, it is relatively quieter but higher frequency.

Not very noisy at all. We use the pumps for a race car driver's cool suit (circulates coolant through a vest to keep the driver cools in a 150 degree environment) so we don't care about noise. But it is almost impossible to tell if the pump is running without touching it.

It is not loud. I use it outside but it is well insulated but has no tank so it does run continuously

I have this pump installed in a building that is insulated ..some times it runs 24 hours a day only run as I need it...I don't have a measure device to tell how loud it is when running. In order to hear it running you have to be with in appox 30 feet from out side of building to hear it running..It is very quite for this type of pump.

This is the second Zoeller pump I have owned. The first one came with my house when I bought it. It was probably 15-20 years old when it finally went. This new one is about the same loudness as the original. You will be able to hear it but its not super loud or anything. Sounds like a normal sump pump should should like. Most of the noise I hear is the water rushing out and the check valve closing.

Its not that loud. I hooked it up then unhooked it and went with a different model.
