It has been 14 months since we’ve purchased our Ionizer Plus water filter and it is still working great.
All the reasons we purchased the filter: the health benefits of high alkaline water, (we are on Level 4), the ultra-violet disinfection, the carbon and the membrane filtrations - are just as valid now as they were the day we purchased the filter and they can all be summed up in the phrase "peace of mind". We just don't worry about the quality of our water. In fact, when the Washington Post recently ran an article about the prevalence of the pesticide atrazine in some drinking water, we were confident that our filter could remove it.
My wife prefers the taste of the water over our tap water and even over most bottle waters. She describes the water as smooth and bright. In fact, she said that she had never before noticed that the average drinking water had any friction to it, until she tasted the ionized water. I prefer it also and I take three 25-oz glass bottles to work every day to drink at my desk.
We have never regretted purchasing this filter for one minute and expect to enjoy the benefits of using it for many years to come.
