I was tired of the bill growing from the water delivery place and the husband didn't enjoy lugging gallons from the store. I only drink distilled water and I use it for pets, ice machine and several other water using appliances. This has been great. We live on a hill top with mostly rock so not much filtering for our water table. We have lots of decaying materials from the woods as well. We also have iron, badly. This is great, I run the tap water through this and then to be honest, I run it through another filtering system to be sure bacteria and viruses are gone. I know what I am drinking, I know it's safe and I control how much I have on hand. I recommend this item.
