We got this to eliminate heavy metals (plus everything else) from our water after my husband was told he had MS. We had been wanting this filter a long time but with the news of his health we couldn't put it off any longer. It was so easy to install, the info said the water would be cloudy for a couple weeks but it was hardly cloudy at all. The quality is amazing, I drink so much more water now, I actually feel it soaking into the tissues in my mouth, something I haven't felt before with any other water. Crazy thing to notice! Our 3 yr old loves water even more now, asks for it all the time compared to the Deep Rock we used to get. My husband loves that there is no aftertaste to it and feels better knowing his water is now pure and free of everything when he has to drink so much of it with his meds. We are soooo happy to have this filter! Anyone on the verge of buying one, just get it, you will be happy you did. Water is getting more precious and so many cities are recycling waste water (and probably not very well) it is worth it for you to take care of your family's health by making sure what you're drinking is safe and pure. Thank you for a wonderful product!!!
