    Prior to purchasing, I was comparing different brands of these types of filters and came to the conclusion of getting this one. I made the right decision. Pro One is just great. I made it an interest to purchase this “Big+ Factory Mis-size” because it is offered at a better price then the original due to its different dimensions from factory, and this way at can get a feel at how the system works before I make the decision to further invest in more Pro One products. Just as the description says, it functions the exact same. I can not recommend this product enough. You can truly see and taste the difference in the water that you will drink. After this, I can never go back to drinking water from anywhere else, and I will in fact be purchasing another one, specifically the travel size.

    We have had this a few weeks and love it so far. If anything we are thrilled to have pure clean drinking water along with knowing if I’m an emergency we can still have clean drinking water for our family.

    I LOVE my new ProOne system! Bought the mis-sized model and it works great. In my opinion, this is the best deal on the market. Been using it a couple of weeks and loving the great tasting water. Thank you for making this available at such a great discount (via the outlet).
