If you are a global importer, distributor, brand seller or public project buyer looking for a reliable gravity water filter supplier in China, this guide will help you find qualified factories, check product standards, and understand key filtration performance for home, outdoor, emergency and remote area markets.
More international buyers prefer sourcing gravity water filters from China because of complete production chains, customizable design, competitive wholesale price and flexible OEM/ODM service. A qualified Chinese gravity water filter manufacturer can supply stainless steel gravity water purifiers, ceramic cartridge models, 15-layer composite filtration types, and built-in ozone sterilization versions for global markets.
We are professional water treatment factory in china this product is innovation by our factory with patent and newest technology ozone fuction
First, sub-micron ceramic filtration with 0.2–0.5μm pore size is a must. It physically blocks sediment, rust, red worms, microplastics, and intercepts E. coli and other intestinal bacteria to reduce waterborne disease risks.
Second, 15-layer composite filtration adds multi-function adsorption. It effectively removes residual chlorine, strange odor, organic pollutants and heavy metals including lead, cadmium, mercury and arsenic, greatly improving water taste and safety.
Third, ozone sterilization becomes a popular upgrade model. It reaches 99.99% sterilization rate against E. coli, Staphylococcus aureus and Salmonella, leaves no chemical residue, and decomposes into oxygen naturally without secondary pollution.
Most buyers also require no electricity, no plumbing, gravity-driven design, portable size and easy filter replacement for household, camping, RV, temporary camps and remote village use.
Core Advantages of Guanya Environmentally Friendly’s Stainless Steel Filter Cartridge
-
- Uniquely designed ozone sterilization and disinfection function: ozone releases a 99.99% removal rate for various bacteria, including Salmonella enterica, Staphylococcus aureus, and E. coli.
- Gravity filtration and a built-in battery for the ozone function allow for use without electricity, including during floods and earthquakes, to meet emergency water needs.
- Corrosion Resistance: Made of food-grade 304 material, it is acid-, alkali-, and chloride-resistant, rust-resistant, and has a service life of over 20 years.
- High Strength: Withstands impacts from outdoor transportation, earthquakes, and falling rocks, without breaking.
- Easy Cleaning: The stainless steel filter cartridge resists dirt and can be rinsed directly with water, meeting emergency recycling needs.
- No excessive maintenance required, easy to clean, and the two-stage physical filter element is flushable and replaceable, resulting in low replacement costs
Detailed Explanation of Ozone Sterilization Function
- Ozone effectively removes organic and chemical pollutants. It oxidizes chromophores in water, such as phenols, diazo, and azo compounds, disrupting their structure. It possesses highly effective bactericidal properties, rapidly destroying the cell walls and membranes of microorganisms such as bacteria, viruses, fungi, and spores, thereby achieving sterilization and disinfection. Its bactericidal power is hundreds of times greater than that of chlorine, and it sterilizes rapidly. Furthermore, ozone effectively removes pesticide residues and produces no harmful disinfection byproducts during the disinfection process.
Typical Application Scenarios
- Daily Home Use: Place under the kitchen or on a countertop to provide low-bacteria, low-heavy-metal soft water for infant formula and pets, eliminating the risks of residual chlorine, lead, and copper in tap water.
- Outdoor Camping: The compact 2.25-gallon barrel fits in the trunk of a car. With the folding stand, river water can be filtered for 30 minutes before drinking, solving the problem of refilling water for hiking, fishing, and RVing.
- Disaster Emergency: When an earthquake or flood shuts down a water plant, the gravity water filter can purify cellar and stream water to drinking standards without electricity. A single filter cartridge can produce 5,000 liters of safe water, meeting the basic needs of a family of five for one month.
- Schools and Hospitals: In rural clinics and boarding schools with unstable voltage or a shortage of maintenance personnel, the stainless steel gravity water filter can serve 50–100 people per day as a terminal water purification station, significantly reducing the incidence of waterborne diseases such as diarrhea. 5. Catering and Brewing: Small cafes and craft breweries use ozone to remove chlorine and organic matter from water, enhancing the taste of their drinks. The stainless steel exterior also meets food production hygiene standards.
