Purification Process

The portable water purifier works by passing contaminated water through multiple layers of filter media:

• Pre-Filter: Removes large particles and debris.
• Sand: Traps smaller particles and sediments.
• Ceramic Filter: Eliminates bacteria, protozoa, and cysts.
• Activated Carbon: Absorbs chemicals, tastes, and odors.

Maintenance and Care

• Clean the ceramic filter regularly by backwashing with clean water.
• Replace the activated carbon every 6 months or as needed.
• Disinfect the entire system with a chlorine solution periodically.

Benefits of a Portable Water Purifier
