At Tonchant, quality is more than a word; it's our promise. Behind every drip coffee bag or filter we produce, there's a careful process to ensure consistent, safe, and superior brewing results. Here are five critical quality control steps every coffee filter goes through before it reaches you.
1. Raw Material Inspection The entire process begins long before production. We carefully select wood pulp, bamboo fiber, or abaca hemp that meets international food-grade standards. Each batch of coffee is tested for fiber length, density, and cleanliness to ensure no contaminants or residues affect the flavor of the coffee.
2. Precision Papermaking Our advanced machinery ensures that each filter is uniform in thickness and weight. Ensuring even fiber distribution is critical to controlling flow rate and extraction rate. Any irregularities are marked and removed before continued use.
3. Lab and Brewing Performance Testing Before mass production, sample filters are lab tested for: Breathability (regulates flow) Tensile strength (avoids tears) Filtration performance (removes fine particles) We also simulate the actual brewing process to ensure the filters work perfectly in real-world pour-over and drip scenarios.
4. Certifications & Compliance Tonchant filters are manufactured to strict ISO food safety and environmental standards. Many of our products are compostable, biodegradable, and meet FDA, EU, and Japanese food contact regulations. Certifications are not marketing gimmicks, but rather a testament to the quality of our products.
5. Final Inspection & Clean Packaging Each filter is die-cut, folded, and shaped—for cone, basket, or drip filters. Our team performs a final visual and physical inspection, then packages it in clean, sealed, recyclable materials ready for global distribution. Why It Matters In specialty coffee, filters are the unsung heroes. Even the slightest difference in pore size or structure can affect taste and brew time.
At Tonchant, we don’t take this lightly. Our filters not only work on paper, they also work in the cup.
