Do you have a spa or hot tub that is really old, not ozone-ready, wooden, or unique in other ways?

DEL Ozone's Portable Purifiers have been purifying hot tubs for over 25-years.  Easy to use, they simply pump ozone into the spa using a little compressor, ozone tubing and a dispersion stone that drapes over the side of the spa wall.  

For decades DEL manufactured the ZO-151 UV-style Portable Purifier and now they offer a new Portable Purifier that uses up-dated CD ozone electrode technology, the ZO-200.
