Do Not Be Misled: The Truth About Electrical Sedimentation Devices and Water Quality
Recently, you may have seen a demonstration using an electrical sedimentation device that changes the color of tap water or filtered water from other systems, while the Camelot® reverse osmosis water does not.
Does this mean that your water is unsafe while Camelot® water is clean? The answer is no.
Sedimentation devices are not reliable indicators of water quality
These devices do not provide valid information about water quality. They are often used as marketing tools to promote certain reverse osmosis filters, misleading consumers into believing their water is contaminated.
Misleading sales tactics
Sellers who use electrical sedimentation devices or water precipitation meters typically mislead consumers by implying that the device can detect harmful contaminants. In reality, these tests only detect inorganic salts or hardness in water and do not reveal the presence of dangerous pollutants.
What the Water Quality Association (WQA) says
The WQA, the largest internationally recognized organization for water quality, explicitly states that electrical precipitation tests are misleading.
From the WQA Statement on Sedimentation Testing: “The Water Quality Association recommends not using electrode-based testing as a method to determine water quality because it is fraudulent. Electrical sedimentation devices release metallic ions (rust from metal rods) into the water, forming visible sediment.”
Why water changes color during the test
Tap water and filtered water from other sources contain inorganic salts that react with the electric current, producing visible changes in color or sediment. This does not indicate harmful contaminants. These minerals are naturally occurring and essential for health.
Reverse osmosis water, by contrast, is free of these minerals and does not react during this test – but that does not mean other water sources are unsafe.
A simple experiment to reveal the trick
To demonstrate the misleading nature of the test, dissolve half a teaspoon of salt in the “clean” water claimed by the seller, then repeat the test. The water will turn dark even though the salt is harmless. This proves that the device does not measure actual safety or purity.
Deionized water is unsafe for drinking
The WQA also explains that deionized or mineral-free water is not suitable for consumption. Its lack of minerals prevents it from reacting to the electric current, making it appear “clean” in the test. In reality, healthy drinking water should contain beneficial minerals. Commercially sold deionized water is intended for appliances, not drinking.
Do not be misled by showy experiments
Always rely on certified laboratories and recognized testing methods to evaluate water quality. Avoid making decisions based on visual demonstrations using sedimentation devices.
Certified Camelot® filters provide a real solution
For safe and clean drinking water, use certified Camelot® filters. These systems are proven to remove dangerous chemical contaminants, using:
-
850 grams of pharmaceutical-grade activated carbon
-
High-quality membrane pores (0.1–0.4 micron)
In contrast, many competitor filters use 30–120 grams of carbon and membrane pores over 0.5 micron, which are far less effective. The difference in water quality is significant – a proper test will confirm it.
Conclusion
Electrical sedimentation devices are not a reliable method for evaluating water quality. They are intended to mislead consumers. To ensure your drinking water is safe, rely on certified filters, laboratory testing, and trusted sources.
