Review on 💦 Enhance your Water Quality with the iSpring F9K Replacement 6 Stage Filtration by Mark Clark

later The initial setup was complicated, the instructions were confusing and YouTube was the only source that helped. After assembly, TDS (Total Dissolved Solids) was higher than that of tap water. I contacted the company and after several conversations concluded that the DIA unit was supplying contaminated water to new water cartridges. The company sent a new ASV-Uniy which improved the quality. The next installation of replacement filters went smoother, but there was still a lot of water on the floor and it took about 3 hours to replace. Water quality was good, pH was acceptable, and TDS was lower than tap water. The third installation of replacement filters included alkaline and mineral filters. The water tasted bad and tasted like plastic which was probably another manufacturing defect. Contacted support and there was no comment on the question, but they sent a different filter. In those days the taste of water was fitting. The final installation should include a reverse osmosis filter. I didn't realize the lack of the reverse osmosis filter until I started replacing the cartridges about 3 months after receiving the replacement filters. This time I decided not to contact support. Will look for a better product with better production methods, instructions to follow, and easier installation next time. I'm done with this system and poor quality
