OEM/ODM Portable Gravity Water Filters for Outdoor

Portable Gravity Water Filters for Outdoor

-- Steady & Reliable Manufacturer --

Introduction to Portable Gravity Water Filters

Portable Gravity Water Filters are simple, highly effective systems designed for outdoor use, emergency preparedness, and remote locations where electricity, plumbing, and pressurized water are unavailable. These systems consist of two or more containers (or bags) stacked vertically, using the force of gravity to push water through highly effective filter elements. The process is inherently slow but exceptionally thorough, typically utilizing advanced ceramic or high-performance carbon/membrane filters capable of removing bacteria, protozoa, and fine sediment.

Ningbo Yaorui Water Purification Technology Co., LTD. manufactures complete gravity filter systems and the essential filter elements (e.g., carbon, ceramic, ultrafiltration) with a focus on ruggedness, lightweight design, and high microbiological safety standards. Our 15 years of quality manufacturing ensures the materials used (food-grade PE, PP, or durable fabrics) are safe, and the filter elements achieve maximum contaminant reduction, often tested to exceed EPA and WHO standards for bacteria and cyst removal.

We are a key supplier to international outdoor retail brands, emergency response organizations, and distributors in regions with unreliable potable water infrastructure. We offer fully customizable systems, guaranteeing flawless quality and operational reliability in challenging environments globally.

The Micron Rating is the most critical specification for safety; our systems utilize UF membranes or fine ceramics to achieve high-log removal of bacteria and cysts. The Flow Rate is inherently slow, dependent on the water level (head pressure) in the upper reservoir, which is a necessary trade-off for such fine filtration. The Filter Life Expectancy provides excellent value, often lasting an individual user for years. We ensure all plastics are BPA-Free and UV-resistant for outdoor durability. We offer OEM customization on container size, color, and filter element configuration (e.g., adding carbon for taste). Every unit is leak-tested, and filter elements are validated for their microbial removal efficiency before bulk export.

Core Advantages of Our Gravity Filters

  • Certified Microbial Safety: Utilizing UF membranes or fine ceramics, our systems physically remove bacteria and protozoa, delivering a level of safety crucial for drinking untreated water sources.

  • Energy and Chemical Independence: Gravity operation requires no electricity, pumps, or chemical treatment, ensuring reliability regardless of infrastructure and maintaining the water's natural taste.

  • Sustainable and Economical: The high-capacity elements (up to 3,000 Litres) and in some cases, the cleanable nature of the ceramic elements, offer extremely low operating costs over the filter's lifetime.

  • Portable and Lightweight Design: We engineer collapsible, durable bag systems and lightweight plastic housing to minimize carry weight for hiking and maximize ease of deployment in emergency scenarios.

  • Durability for Outdoor Use: All components are made from high-strength, UV-resistant, food-grade materials to withstand rugged outdoor handling and variable temperature conditions.

These advantages make our gravity filters the preferred choice for reliable, off-grid water safety globally.

Essential Applications for Gravity Filters

Gravity filters are vital where simplicity, portability, and safety from natural water sources are required.

  • Camping, Backpacking, and Trekking: Providing safe drinking water from rivers, lakes, or streams during extended outdoor trips.

  • Emergency and Disaster Preparedness: Essential part of survival kits, allowing users to safely treat non-potable water sources when municipal supply is compromised.

  • Humanitarian Aid and Mission Trips: Providing simple, communal filtration for communities in developing regions without centralized water treatment or power.

  • Cabins and Remote Homes: Used as a simple, high-barrier system for safe drinking water when the well or cistern water quality is questionable and only needs small-volume purification.

  • Educational and Research Fieldwork: Offering researchers a reliable method to obtain safe drinking water while working in remote, wilderness locations.

These applications leverage the system's independence from power and pressurized plumbing.

Payment and Shipping for International Orders

We are committed to providing seamless and competitive logistics solutions for our international clientele. Located in the strategically important Ningbo Seaport City, we maximize efficiency and minimize shipping costs for global exports.

  • Payment Terms: We typically accept Telegraphic Transfer (T/T). For established partners, terms like L/C at sight or deposit plus balance upon B/L copy may be offered. Minimum Order Quantities (MOQ) apply for OEM and custom manufacturing to ensure efficiency.

  • Shipping Logistics: We offer FOB Ningbo and CIF to major international ports. Gravity filters are lightweight, making LCL (Less than Container Load) shipping efficient. We ensure specialized packaging to protect delicate ceramic/membrane elements during transit.

  • Lead Time: Standard lead time for production and quality control checks is generally 35-45 days after deposit, due to the specialized element assembly and final system testing.

  • Documentation: We provide comprehensive export documentation, including Commercial Invoice, Packing List, Bill of Lading, and Certificates of Origin as required. Microbial reduction test reports are available for compliance.

We ensure operational reliability in logistics, guaranteeing your outdoor and emergency systems arrive safely and ready for deployment.

Frequently Asked Questions (FAQs)

  • Q: Will this filter remove viruses?

  • A: The finest Ultrafiltration (UF) membranes (∼0.01 micron) used in some of our gravity filters can physically remove most viruses, but performance varies. For guaranteed virus removal, additional treatment like UV light or chemical disinfection is recommended alongside UF or ceramic filtration.

  • Q: How fast does the water filter?

  • A: Flow rate is slow, typically 0.5 to 3 litres per hour, depending on the filter type and the cleanliness of the source water. This slow rate ensures the water has sufficient contact time with the fine media for high pathogen removal.

  • Q: Can I use this filter with turbid (muddy) water?

  • A: Yes, it is designed for it, but the filter element will clog quickly, reducing the flow rate. Always pre-filter turbid water by straining it through a cloth or allowing the sediment to settle first. Ceramic elements can then be cleaned to restore flow.

  • Q: Do I need to clean the filter element?

  • A: Yes, especially ceramic and UF elements. When the flow rate slows significantly, the external surface needs to be cleaned (scrubbed gently with a pad for ceramic, or back-flushed for UF membranes) to maintain performance and extend lifespan.
