This has been a subject I've done a lot of 'soul searching' on myself...so I know what you're going through! I needed to find the best method for my daughter in college to purify her own water. Not only was it extremely important to me that the water was pure, it had to be health promoting...not health destroying! Also, in her situation, she needed something portable, low maintenance and not too costly. After carefully evaluating all the options, I ended up purchasing a steam water distiller for her with a glass container (Love Model 3).
