starts out a little noisier but then settles down to a low hum, its quieter than the noise of the bubbles. huge improvement over my last blower, definitely recommend, worth getting a plug from them, the plug it comes with is very short.

This product works just as advertised. Works great for our project.

This blower was installed on the hot tub side of our dual temp swim spa. The 1.5HP version was previously installed by the previous owner, and I believe user error caused it to burn out. I chose the 1HP version due to the small size of the spa. It has been working great, provides plenty of air, and is quiet enough that I don't notice it over the sound of bubbles. I am happy with the purchase so far, and spadepot.com has been great to work with.

Works great, and was super simple to install

Direct replacement. Plugs right in.
