I'm using the espring for my drinking water, and for outdoor filter, i'm using Pentair, the filter was used in many countries, especially in White House, Starbucks etc. During the flooding happened in Thailand recently, the Thai government had been using more than 5 espring to filter the water for the victims.

Please bear in mind that don't ever drink RO water, it is only recommended for patient because RO water too clean, until it will washed out the minerals in our body, especially our calcium and causing many diseases.

If someone need more details, do PM me or call me at 0126647964. I will be willing to share.
