I love this these products. I have a for home and a travel bottle for when away from home. They both require different filters. I have been using these since 2018 & will not use another type of water system now. The alkaline test to what it's suppose to (I use test strips and just don't remember what the Ph range is suppose to be). The LED counter on the lid of my pitcher quit working after the warranty had expired, I contacted Invigorated and they replaced it free of charge. I will continue to support this company & will always use alkaline water from now on.
