12V UV Water Filter Systems for Caravans, Boats & Motorhomes
Protect your health with compact, energy-efficient LED UV water disinfection. Designed for mobile leisure—powered by 12V. Mercury-free. Maintenance-free.
Why Choose a 12 Volt UV Water Purifier for Travel?
When you're off-grid or travelling in remote areas, a 12 volt UV water purifier ensures your drinking water is free from harmful pathogens like E. coli, Cryptosporidium, Legionella, and Pseudomonas. Unlike chemical disinfection, LED UV water filters offer instant, chemical-free purification.
LED vs Mercury UV – The Clean Advantage
Most traditional UV systems rely on mercury lamps. Here's how LED UV-C technology is better:
✅ Mercury-free – safer and environmentally friendly
✅ Low power consumption – ideal for 12V power supplies
✅ Instant on/off – activates only when water flows
✅ Longer lifetime – over 8 years at average daily use
✅ Compact & durable – perfect for mobile leisure installation

Customer Testimonial
I have a Campervan with 170ltr water tank, the Water is filtered through a 3 stage system as it enters the tank: 20, 5 & 0.05 micron. Then as water is pumped to the taps etc it passes through the Micro 12C-450 LED UV steriliser .
Your PearlAqua Micro LED 12 Volt UV purifier is perfect for many reasons.
1. It activates on demand
2. It's Small
3. It only requires 12 volts
4. Great quality
​
I would and already have highly recommended your product to fellow van’ers.
Your communication and timely order turn around are great. Customer service seems quite distant in many companies. But not yours.
​
Thank you

How It Works – Point of Use LED UV Disinfection
LEDs emit UV-C light that destroys the DNA of harmful microorganisms instantly. Our 12V UV filters activate only when flow is detected, ensuring energy efficiency and safety, even in mobile applications.
>99.99% Disinfection
Utilising UV-C light alone, the DNA within the cell of the micro-organism is disrupted preventing replication. The Miro-organism is effetely dead and cannot cause waterborne illness'. The PearlAqua 12C and Deca 30C offers a flow rate of 8 lpm at a UV dose 10mj/cm and 12 lpm at a UV dose 30mj/cm which is sufficient to inactivate >99.99% of E.Coli, Legionella pneumophila, Pseudomonas aeruginosa and Cryptosporidium. Run units in parallel to achieve higher flow rates.
Years of Use
LED Technology allows the UV system to achieve power up and achieve instant kill intensity as soon as flow is initiated therefore treating 100% of the water throughput. In addition the Mirco 12C and Deca 30C UV System can switch on and off unlimited times over the course of its 8,000/10,000 hour lamp operational lifetime, therefore providing in excess of 8 years use if used for 2.5 hours a day every day of the year.
Simple Integration
Utilising 3/8" pushfit connections for the PearlAqua 12C & 3/8" BSPM connections for the Deca 30C, The PearlAqua UV Systems can be easily installed into the water pipe distribution system within a Caravan, Motorhome or Yacht. The integrated flow sensor detects waterflow and brings the unit online giving an LED lamp indication that the system is powered. A simple connection to a 12VDC supply or plug directly into a 240V socket using the optional power adaptor is all that is needed to run the device.
