Marquis was supposed to be one of the first companies installing it on their spas but they are pushing it back until next year apparently, something about inventory.
The microsilk has been used in the high end bath industry for a few years and now Balboa seems to be taking to the hot tub guys.
The only thing I know is what I have been told from the Marquis reps and the videos you can find on youtube.
It is basically a secondary motor with lots of impellers that chop up air molecules. You spa will turn milky white , but it is just air bubbles.
Marquis had it running on a couple of show models, and from everyone who i've talked to you can feel a difference.
My problem is with the cost....you will be paying around $2,000 extra to have this system installed on a new spa. I could see dealers adding it in at maybe $1600-$1800.
But only the biggest dealers who inventory dozens of spas will risk setting one up on the floor. I think a lot of smaller dealers (like me) who can only have 6-8 tubs on the floor won't be willing to order one in for wet test so it will be hard for consumers to try out.
I am no Doctor but the science seems sound regarding its benefits, just not sure how the cost/benefit ratio is.
