Make sure to check out other dealers of water purification systems in the genearal area, and KNOW YOUR PRODUCTS and what they can do. The owner is a a kind of cult leader in a local so-called Orthodox Christian church, but his prices are very high compared to other dealers, despite his on-line claims. Also, many of the systems he promotes require expensive upkeep that he charges high prices for, and which one could easily do oneself. Not a very honest dealer, compared to others.
