Celrith cylindrical humidifier filters (water spray type) are designed to remove waterborne impurities and airborne particles from humidification systems while adding moisture to the air. They filter out calcium and magnesium ions that cause white dust, trap odour-causing compounds, and inhibit microbial growth, making them ideal for residential humidifiers, air purifiers with humidification, and industrial humidity control equipment.
Water used in humidifiers is rarely pure. It carries dissolved minerals—primarily calcium and magnesium—that, when released as fine dust, settle on furniture and electronics. Organic matter and bacteria in the water tank decompose and produce musty odours. Airborne particles drawn into the unit can combine with moisture to form deposits on the filter surface. Over time, these contaminants reduce output and create an unpleasant environment. Celrith filters address these issues by using high-capillary humidifier paper or polymer fibre that rapidly wicks water and releases moisture, while its structure and optional antimicrobial treatment intercept minerals and suppress odour and mould.
When a humidifier operates with a saturated or clogged filter, the fan and pump must work harder to maintain output, increasing energy consumption and wear. Mineral scale stiffens the filter, reducing its evaporative surface and forcing the system to run longer. In industrial settings, unstable humidity can affect product quality and equipment reliability. A properly functioning filter reduces this load by maintaining high evaporation efficiency and low resistance to airflow, allowing the system to operate at optimal conditions. The Celrith filter's high wet stiffness prevents collapse even after prolonged immersion, ensuring consistent performance.
Celrith filters are engineered with a dense pleated honeycomb structure that provides a large evaporation area and rapid capillary action. The material absorbs water quickly and releases it efficiently, helping to achieve humidification efficiency above 85% under standard conditions. The filter is available with built-in antimicrobial protection (optional silver-ion or nano-photocatalyst coating) that inhibits bacteria and mould, reducing odours and secondary contamination. The high wet stiffness of the filter ensures it does not sag or disintegrate in the water tank, maintaining structural integrity throughout its service life. Celrith also offers 100% OEM customization: you can specify outer diameter, inner diameter, height, pleat count, and whether to include antimicrobial coating, all precisely manufactured to your drawings.

Our in-house CNAS-accredited laboratory supports filter efficiency, dust-holding capacity, and resistance testing, giving you reliable data for your product development. With a 50,000 m² production base including 20,000 m² of cleanrooms across six workshops, and over 20 years of experience in filtration, we have developed more than 1,000 filtration solutions for customers in Europe, the US, Japan, and Korea. Our multiple automated production lines achieve monthly capacity in the millions of pieces.
To help us recommend the right Celrith cylindrical humidifier filter for your application, please provide the following details: your device or vehicle model, required dimensions or a drawing, target airflow or water flow rate, operating conditions (water quality, temperature, humidity), and estimated quantity. Our team will respond promptly with a tailored solution. Contact us to discuss your requirements or request a sample.
It intercepts calcium and magnesium ions in water to prevent white dust, traps airborne particles, and with the optional antimicrobial coating inhibits bacteria and mould that cause odours. It also helps remove existing tank odours through its antimicrobial and anti-mould properties.
Under standard conditions, the humidification efficiency can reach above 85% thanks to the large evaporative surface of the pleated honeycomb design. The expected service life is 6–12 months, depending on water quality and usage frequency. Regular replacement maintains performance and prevents mineral buildup.
Yes, Celrith offers 100% OEM customisation. You can specify the outer diameter, inner diameter, height, pleat count, and whether to include an antimicrobial coating. Simply provide your drawing or dimensions, and we will manufacture to your exact requirements.
The MOQ for standard specifications is typically 3,000 pieces, while custom products generally require 5,000 pieces. Standard items ship in 7–15 days; custom samples take 7–10 days, and mass production takes 30–45 days. For large or long-term orders, we can arrange VMI stocking and priority scheduling.
Yes, we provide 1–3 free samples of standard specifications; you only cover the international courier cost. Custom samples incur a sampling fee, which is refundable upon mass production. Each sample can be accompanied by a CNAS laboratory test report covering water absorption, humidification efficiency, and material safety.
Celrith filters are manufactured under ISO 9001, ISO 14001, and IATF 16949 quality systems, and comply with REACH and RoHS regulations. Our CNAS-accredited lab provides test reports for efficiency, resistance, and other parameters. We can also support you in obtaining destination-country certifications as needed.
The filter can be supplied with a silver-ion or nano-photocatalyst antimicrobial coating that inhibits common bacteria and mould, reducing secondary contamination and odour. The coating is optional and can be specified during customisation. For standard products, the antimicrobial treatment is available upon request.
We recommend replacing the filter every 6 to 12 months, depending on water hardness and usage hours. In hard water areas or continuous operation, more frequent replacement may be needed. Timely replacement ensures efficient humidification and prevents mineral scale from reducing airflow.
