The three-stage filtration was definitely noticeable. I tested the water quality before and after using a home TDS meter, and the difference was clear. The efficient 2:1 pure to drain ratio meant I wasn’t wasting much water, which made me feel better about the environment and my water bill. The high 1,000 gallons per day capacity meant the system never slowed down, even when multiple people in the house used water throughout the day.

After using the system for several weeks, I found it continued to perform reliably without any drop in water quality or flow speed. The filters seemed durable, and maintenance was simple enough to handle on my own. Overall, the APEC Tankless Reverse Osmosis System proved to be a dependable and efficient way to get clean, great-tasting water right from the tap every day.
