What are UV Water Purifiers?

How UV Water Purifiers Work

UV water purifiers harness the power of ultraviolet (UV) light to disrupt the DNA and RNA of harmful microorganisms, effectively inactivating and rendering them unable to reproduce or cause disease. As water passes through the purifier, it is exposed to a specific wavelength of UV light (typically between 200-280 nanometers) that penetrates the cell walls of bacteria, viruses, and protozoan cysts, preventing their replication and survival.

The effectiveness of UV water purifiers in killing microorganisms depends on several factors, including the intensity and duration of UV exposure, water clarity, and the specific types of contaminants present.

Benefits of UV Water Purifiers

One of the primary advantages of UV water purifiers is that they do not require the addition of chemicals or other substances to treat the water. This not only preserves the natural taste and odor of the water but also eliminates potential health risks associated with chemical byproducts.

UV water purifiers are also relatively low maintenance compared to other purification methods. Once installed, they typically require minimal upkeep beyond periodic replacement of the UV lamp and occasional cleaning of the quartz sleeve that houses the lamp.

Furthermore, many UV water purifiers are designed to be compact and portable, making them an attractive option for preppers who may need to transport or set up water purification systems in various locations or during emergencies.

The Experiment

To truly evaluate the performance and reliability of UV water purifiers, I decided to conduct a month-long experiment using one in my daily life. As a prepper living in a rural area with a well water source, ensuring access to clean drinking water is a top priority.

Setup and Methodology

My living situation consists of a small homestead with a family of four. Our daily water needs include drinking, cooking, and basic sanitation. For the experiment, I installed a countertop UV water purifier from a reputable brand, the Aqua-Pure AP801, which is designed to treat up to 12 gallons of water per minute.

To assess the purifier’s effectiveness, I collected water samples before and after treatment at regular intervals throughout the month. These samples were tested for the presence of common contaminants, including:

  • Total coliform bacteria
  • E. coli
  • Turbidity (cloudiness)

Additionally, I maintained a daily log to record any observations regarding water quality, taste, and any issues or unexpected events during the purification process.

Day-to-Day Observations

During the first week of using the UV water purifier, I noticed a slight improvement in water clarity and a reduction in any residual chlorine taste from our well water.

However, on the fifth day, the purifier’s UV lamp indicator light began flashing, indicating a potential issue.

Upon further investigation, I discovered that the quartz sleeve surrounding the lamp had accumulated some mineral buildup, which can reduce the UV light’s effectiveness. After cleaning the sleeve, the purifier operated smoothly for the remainder of the month.

As the experiment progressed, I observed consistent water quality, with no noticeable changes in taste or odor. However, it’s important to note that my well water had relatively low levels of contaminants to begin with, which may have influenced the results.

Overall, the day-to-day experience of using the UV water purifier was positive, with minimal maintenance required beyond the initial sleeve cleaning.

UV Water Purifier Effectiveness

To comprehensively evaluate the UV water purifier’s effectiveness, I employed both professional lab testing and anecdotal feedback from my family’s experience.

Lab Testing Results

The water samples collected throughout the month were sent to a certified laboratory for analysis. The test results revealed the following:

ContaminantBefore TreatmentAfter UV Treatment
Total Coliform Bacteria8 CFU/100mL0 CFU/100mL
E. coli0 CFU/100mL0 CFU/100mL
Turbidity0.8 NTU0.3 NTU

CFU: Colony-Forming Units, NTU: Nephelometric Turbidity Units

As the data shows, the UV water purifier effectively eliminated total coliform bacteria and maintained the absence of E. coli in our water supply. Additionally, it reduced turbidity levels, improving water clarity.

However, it’s important to note that while UV purifiers are highly effective against bacteria and viruses, they may have limitations in treating certain protozoan cysts, such as Cryptosporidium and Giardia, which can be more resistant to UV light.

Anecdotal Feedback

Throughout the experiment, my family and I did not experience any adverse health effects or digestive issues related to the treated water.
