I am a Natural Health Practitioner for over 40 years. Since I have been a young child I have had problems drinking tap water and I never knew WHY. It wasn't til many years later that I realized I was chocking on the fluoride and the chlorine that is in tap water. Even most bottled waters I had a problem with as they are NOT as pure as they state they are. After several years of dedicated research to find the BEST water system; several years ago I had decided that the R/O was the best overall, in that it removed the fluoride as well as all the rest of the garbage in the water which is enough to make anyone ill. it was also affordable; but it wasted a LOT of water. Right before I purchased the R/O, I had discovered the Alkaline Water Machine. Very costly, but, it seemed to fit all the other criteria; that one should use when purchasing a water system and I could get one with a fluoride removing filter. After spending over $1200 for this machine.(which was cheap next to what the other Alkaline machines were going for)..and removing my expensive pull out faucet in my kitchen; and replacing it with an regular kitchen faucet; the connectors still would NOT fit in my kitchen so it wound up in a bathroom. Very inconvenient to have till up water bottles in a bathroom and bring it down to my kitchen and then fill up a glass 2 gallon bottle in order to have water readily available to me in the kitchen to drink and use. Then, there was the costs of the filters that were suppose to last 1 year; which did NOT even last 6 months (and I am only 1 person drinking the water.)..so after all this, the water was good; but, tooo many problems to live with. So for the next year or more I had been buying water by the gallon and transporting it home to place in my 2 gallon water reservoir . I finally got tired of this routine and went back on line and started researching again; almost bought the R/O til I found the PureEffectFilters site...and NOT only did they overcome all the problems of water, including the Heavy Metals, Chemicals, Fluoride and Chlorine and Radiation problem; but to my delight.....it was very very Affordable and easy to install, not using much counter space and for the last OVER 1 month now I have been enjoying drinking water by 16oz glass; many times a day. I cook with it; and drink with it...and LOVE IT, Just really LOVE IT! I have been recommending it to all my friends and associates and they want it too (as they all know how many years I have been researching for a really good water system) I would certainly urge any and everyone to save yourself YEARS of research, and buy this water system. It has EVERYTHING that all the other systems have individually, and it is in one affordable water system. thank you IGOR, for creating the BEST and MOST affordable WATER SYSTEM that anyone can find!
