I bought and used two (CS-2500P) and two (CS-2500) in New York where TDS levels are around 40ppm. Bay Ridge Brooklyn to be exact. Installed one in my apartment and one in my house. Pros - Easy to install - Took less than 20 minutes - No extra parts required - Great water flow when new - No more red spots in my humidifiers Cons - It takes about 2 months for the water flow to drop by a third compared to when new. I replaced it after 3 months with the same result. We removed the system from the apartment because it was too slow and expensive to replace every 3 months. . I'll do the same at home and find something more economical.
