Review: Great system- 000 PPM - Saves $100's in bottled water - I recently installed this water purification system, and it has exceeded all my expectations. After extensive research, I chose this system to address the quality of my well water, which contains significant sediment. To ensure the best results, I pre-filter my water at the pump using a series of sediment filters before it reaches the Geekpure purification system at my sink. The results are impressive. When I tested the purified water, it consistently showed 000 ppm, indicating absolutely no dissolved solids. The water is crystal clear, with no detectable flavors or odors. It's refreshing to finally have pure, clean water straight from the tap. The system is easy to install and maintain, and its performance has been consistently reliable. This purification system has significantly improved our water quality to the point I do not need to purchase gallons of purified water from the store, and I highly recommend it to anyone dealing with well water.
Review: Great ro for price, easy installation - Jan 20th 2026, I am ordering my 3rd unit for my master bath room. Oldest unit is 4 years old and works great, cheaper than buying the filters! CONTRARY to other reviews this unit is very fast but you may need a pressure tank. Excellent product! Great ro unit, flow rate and recovery higher than more expensive systems, works better with a tank. I have 2 units now! One in my home and one in my rv. Needs on/off control as it runs all the time without shutoff. I used a 13 volt solenoid in rv and pressure regulator in home.

- DI filter is different from other filter , the general filter element when the service life is reached and there is no hint, but when the DI filter element sends out rotten egg taste, it means that the filter element has been filtered for a long time and has reached a saturated state, continued use not only affects the water quality and taste, but also may reduce the filtration effect. Please replace a new filter element, water is more secure. Generally , the DI filter can be used for 3-6 months,please attention to the connection only after the RO machine, if the direct filtration of tap water or well water, the filter element life will be very short
- Life time :6-12 months (Depends on Usage Amount and Feed Water Quality)

### ⭐⭐⭐⭐⭐ Best filter in its class
*by J***L on July 24, 2025*

First class. Best in price and performance. Not my first RO system, but the best I've owned. It takes my city water from 8+ pH to 6.0-6,2 with a TDS near ZERO and it makes over 20 gallons in just a few hours. Just have to supplement the minerals with "Replenish" and adjust the levels to your needs. Don't replace old spent $$ filters on your old RO System, step up and replace the whole system as a unit.
