What Clients Say
Impressive, Necessary and Thankful for this Company! The staff at this office serves as an example of phenomenal customer service which should be admired by all companies. This office assisted us with the reverse osmosis filtration replacement. Joe was very patient with us and taught us exactly what to do and informed us of the best methods of procedures moving forward to replace our filters. After a while, we received a coupon in the mail for a discount on the purchase of filters after we had purchased filters from them. We brought in the purchased filters and decided to purchase filters for the following year since the discount would take affect. John assisted us and made the transition smooth. We saved a considerable amount of dollars on the purchase of the filters. John also reiterated the process of changing out the filters and was very patient with us even though he was swamped. Now, the impressive part. We have a particle meter (not sure of the name) which measures the parts per million of impurities in the water. You can buy once for less than $15. Distilled water has 0ppm, bottled water has anywhere from 12 to 15ppm. The water out of the reverse osmosis system is an outstanding 6ppm after the filters were replaced. The concentration measure 8 to 9ppm prior to replacing the filters. Wouldn't use any other company and strongly recommend this office.
