Ranveth paper-based humidifier filters are cylindrical or custom-shaped humidification media made from high-absorbency humidifier paper or polymer fiber. They draw water rapidly by capillary action, release moisture evenly, and capture calcium and magnesium ions to reduce white dust. These filters are designed for household evaporative humidifiers, premium air purifiers with humidification, and industrial constant-temperature and constant-humidity equipment.
The performance of a humidifier filter comes from how its media and structure work together. Ranveth pairs high-absorbency humidifier paper with a dense pleated honeycomb build. The paper provides strong capillary action, pulling water upward and holding it across the surface. The honeycomb pleats create a large evaporation area, so air passing through the filter picks up moisture efficiently.
This pairing also affects airflow resistance and service life. The pleated structure keeps the media open, allowing air to move through without excessive pressure drop. The paper is selected for high wet stiffness, which means the filter resists collapsing or delaminating during long periods of immersion in the water tank. Anti-microbial and anti-mold treatment helps prevent odors and bacterial growth, keeping the humidified air fresh.
For buyers, the result is a filter that balances three factors: moisture output, energy use, and replacement frequency. A well-matched media and pleat pattern can maintain strong humidification while keeping resistance low, and the wet-strength paper supports a stable structure throughout its service life.

Ranveth paper-based humidifier filters are used in household cold evaporation mist-free humidifiers, where they provide moisture without visible mist. They are also specified for premium air purifiers that combine particle filtration with humidification, and for industrial constant-temperature and constant-humidity equipment that requires stable moisture output.
In each application, the filter's ability to absorb water quickly and release it evenly helps maintain consistent humidity. The anti-mold and anti-microbial treatment addresses common issues such as tank odors and bacterial growth, while the interception of calcium and magnesium ions reduces white dust on furniture and surfaces.

Ranveth paper-based humidifier filters use high-absorbency humidifier paper or polymer humidifier fiber, formed into a dense pleated honeycomb structure. This combination provides strong capillary water absorption and a large evaporation area, while the paper's high wet stiffness prevents collapse during immersion. The media can also include an anti-microbial and anti-mold coating to inhibit odors and bacterial growth.
The pleated honeycomb design increases the surface area available for evaporation, which improves moisture output. At the same time, the open pleat pattern allows air to pass through with relatively low resistance, helping to maintain energy efficiency. The structure also supports the media, keeping it stable when wet.
Yes, we offer 100% OEM customization. We can manufacture cylindrical filters to your specified outer diameter, inner diameter, height, and pleat count, and can apply anti-microbial coatings as required. For other shapes, we work from drawings or samples to match your device.
Under normal usage, the filter typically lasts 3 to 6 months, depending on water quality and usage frequency. The anti-microbial and anti-mold treatment helps maintain performance over this period. We recommend monitoring for reduced humidification output or visible buildup to determine the right replacement time for your conditions.
For standard specifications, the MOQ is usually 5,000 pieces, but this can vary by style. Custom products have MOQs based on tooling and material requirements. We can also arrange sample orders flexibly to support your evaluation.
Sample orders are typically arranged quickly, with timing confirmed based on the specification. For bulk orders, standard lead time is 15–25 days after order confirmation, and 30–45 days for larger volumes. Custom projects that require new tooling may need an additional 7–15 days for sample approval.
Yes, we welcome sample requests. For standard products, we can provide small samples free of charge, with the customer covering international shipping. For custom samples requiring tooling, a sample fee may apply, which can be credited against a bulk order. Our CNAS-accredited lab can also provide test reports to support your verification.
We manufacture in a 50,000 m² facility with six cleanrooms totaling 20,000 m², and we operate under ISO 9001, ISO 14001, ISO 45001, and IATF 16949 quality systems. Our CNAS-accredited laboratory tests raw materials and finished products for parameters such as absorption rate and antimicrobial performance. IQC, IPQC, and OQC processes are applied throughout production to maintain batch-to-batch consistency.
