We recently put in a new pool and were enjoying it immensely, but one thing that was consistently annoying was the constant hum sound from the filters and pumps, which was audible from both the hot tub and the pool. If we were listening to music, we had to turn it up to an unusually high volume in order to hear it comfortably over the sound of the filters. I did some quick searches online to see if there was a solution to this problem, and that's where I came across the Premier Innovations product. I was admittedly a bit skeptical at first, particularly regarding the claim of 90% noise reduction, but figured it was worth a try. I can say unequivocally that the difference was obvious, immediate, and dramatic. Further, the product is remarkably simple to use and easy to install. The only sound we hear from the pool now is sound of water from the waterfall. It has quite literally changed our pool experience. It is a great product and I'd recommend it wholeheartedly.
