Save money and energy with the 100% solar powered savior pool filter from Natural Current, which runs silently from just the power of the sun. You'll be able to turn off your inefficient, noisy and expensive-to-operate pool equipment and both reduce pollution and save money for you and the planet. Pool owners with conventional pool pumps and filter systems spend roughly $1.00 to $5.00 every day or $30 to $150 every month on electricity. The savior can reduce that expense and in many cases eliminate it completely throughout the year. Installation is as easy as taking the Savior out of the delivery box and placing it on the surface of your in-ground or above ground swimming pool or spa. You won't need to worry about buying and installing batteries or connecting it to your existing pool equipment. Easily portable, the savior works in both sunny and cloudy weather-you don't need to live in an all-sun-all-the-time climate to reap the benefits of this solar-powered water filter tool. (During periods of heavy use, inclement weather or larger pools, your existing pool pump can always be run for a few hours here and there as a supplement to maintain filtered water.) The Savior is powered by a two 60-watt, 12-volt solar panel made of tempered glass. The Savior float and solar panel has a life expectancy of 30 years and you can expect to spend approximately $50 every 1 to 2 years on normal unit maintenance (including replacing the pump or filter). Made in USA.
