The corrugated filter is the core component of the evaporative humidifier. It adopts a unique wavy pleated structure design. By increasing the contact area and optimizing the airflow path, it significantly improves the water evaporation efficiency. At the same time, it has the characteristics of anti-scaling, antibacterial, and easy maintenance, providing stable and healthy humidified air for home and commercial scenes.
Core functions and technical characteristics
Advantages of corrugated structure
Ultra-large evaporation area: The wavy pleats (depth 5-15mm) increase the effective evaporation area by 2-3 times compared with the flat filter element, and the humidification efficiency reaches 500-1000mL/h (depending on the model and humidity conditions), quickly alleviating the dry environment.
Uniform moisture distribution: The capillary action of the fiber or aluminum foil material combined with the corrugated guide groove ensures uniform diffusion of moisture and avoids local uneven dryness and wetness.
Efficient purification and antibacterial
Multi-layer filtration:
Surface coarse layer: intercepts large particles of impurities such as mud, rust, etc. in the water (≥50μm);
Deep adsorption layer: activated carbon or ion exchange resin coating to reduce calcium and magnesium ions (scale) and chlorine residue.
Antibacterial treatment: silver ion impregnation or photocatalytic (TiO₂) coating to inhibit the growth of bacteria (such as Legionella), with an antibacterial rate of ≥99%.
Durable and environmentally friendly design
Anti-scale material: corrosion-resistant synthetic fiber (such as PET) or anodized aluminum substrate, with a lifespan of up to 2-4 years (6-12 months for ordinary filter elements);
Recyclable cleaning: supports water rinsing or white vinegar soaking to completely remove scale without frequent replacement of consumables.

Typical application scenarios
Family health:
Winter heating room: fight against skin tightness and nasal and throat discomfort caused by dryness;
Mother and baby bedroom: gentle humidification to avoid sensitive skin problems of infants and young children.
Office and business:
Office building central humidification system: balance the humidity of open office areas and improve employee comfort;
Gym: relieve dry breathing after exercise and suppress odor in the locker room.
Special environment:
Art studio: protect oil paintings, wood carvings and other artworks from cracking;
Data center: maintain a constant humidity environment to prevent electrostatic damage to electronic equipment.
Maintenance and use guide
Installation adaptation
Model matching: adapt to mainstream brands (such as Boneco, Honeywell, Dyson evaporative models), flexible customization of size (common 200mm×300mm).
Water tank compatibility: directly placed at the bottom of the water tank, the snap-on design does not require tools for installation.
Cleaning and maintenance
Daily maintenance: remove the filter element weekly and rinse the surface sediment with clean water;
Deep cleaning: soak it in citric acid solution (1:15) for 20 minutes every month, and gently wipe the corrugated gap with a soft brush;
Dry storage: dry it thoroughly during non-use to prevent mold growth.
Replacement reminder
Performance degradation: humidification efficiency is reduced by 40% or the filter element is obviously hardened;
Structural damage: corrugation deformation or coating peeling affects the antibacterial effect.
Technological innovation and trend
Intelligent humidity control: some high-end models integrate humidity sensors, automatically adjust the wind speed, and accurately control humidity by ±5% RH;
Nano-hydrophobic coating: the surface mimics the lotus leaf effect, reduces scale adhesion, and extends the cleaning cycle by 2 times;
Environmentally friendly material upgrade: bio-based polylactic acid (PLA) fiber, the degradability rate is ≥90%, reducing plastic pollution.
The corrugated filter has become the representative of humidifier technology innovation with “efficient evaporation, long-lasting durability, health and environmental protection”. From homes to commercial spaces, it redefines the quality standard of humidified air with scientific structure and intelligent design, making every drop of water vapor pure and safe.
