The treated non-woven fabric filter is a core filter component designed for evaporative or cold mist humidifiers. Through a specially treated synthetic fiber structure, it simultaneously achieves the triple functions of water purification, antibacterial and mildew prevention, and anti-scale deposition. With its core advantages of high cost performance, easy maintenance, environmental protection and safety, it has become an ideal solution for ensuring healthy and humid air in home, office and medical scenarios.
Core functions and technical characteristics
Multi-layer composite structure
Pre-filtration layer: coarse-effect fibers intercept large particles of impurities (such as mud and rust) to prevent clogging of the evaporation core;
High-efficiency adsorption layer: high-density non-woven fabric (weight 80-150g/㎡) captures calcium and magnesium ions and chlorine, reducing scale and “white powder” pollution;
Antibacterial treatment layer: silver ion or nano zinc oxide coating inhibits the growth of bacteria (such as Legionella) and mold in water, with an antibacterial rate of ≥99.9%.
Intelligent moisture management
Uniform water absorption: The capillary action of the fiber ensures uniform diffusion of water and improves evaporation efficiency (humidification capacity 300-600mL/h);
Quick drying: After shutdown, the fiber structure accelerates the evaporation of water to prevent the filter element from getting damp and moldy.

Five core advantages
Advantage dimensions User value
Healthy humidification Intercept impurities and bacteria, eliminate “white fog” pollution and respiratory irritation
Economic and durable Washable design, single-piece filter element cost as low as 0.5 yuan/day
Hard water adaptation Reduce scale deposition and extend the life of the humidifier by more than 50%
Silent and energy-saving Low resistance structure + natural evaporation principle, noise ≤28dB (A)
Quick installation Plug and play, compatible with most models (no tools required for disassembly)
Typical application scenarios
Home environment:
Hard water areas: reduce the damage of scale to the ultrasonic blade of the humidifier;
Families with children: prevent bacteria from spreading with water mist and protect children’s respiratory health.
Business and medical:
Hotel rooms: eliminate odor in water tanks and improve the stay experience;
Dental clinics: maintain humidity in the treatment room to prevent equipment from rusting.
Special needs:
Plant greenhouses: humidify evenly to avoid blade scale accumulation;
Musical instrument storage room: stabilize humidity (45%-55% RH) to protect wooden musical instruments.
Maintenance and use guide
Daily cleaning
Weekly rinse: remove the filter element and rinse the surface deposits with clean water (avoid brushing to damage the fiber);
Monthly disinfection: soak in white vinegar solution (1:10) for 15 minutes to remove scale and biofilm.
Replacement signal
Performance degradation: humidification efficiency is reduced by 30% or the filter element becomes obviously hard and discolored;
Odor generation: long-term uncleaning leads to microbial growth and musty odor.
Environmental treatment
Degradable model: After shredding, it is treated as kitchen waste, and the natural degradation cycle is ≤180 days;
Conventional model: Separate the metal support frame (if any) and recycle it according to the classification of plastic waste.
Technological innovation and trend
Intelligent sensing: Some filter elements are integrated with color-changing indicator strips, which automatically turn red to remind cleaning when scale or bacteria exceed the standard;
Photocatalytic upgrade: TiO₂ coating + UV module linkage to achieve the “filtration-sterilization-self-cleaning” cycle;
Bio-based materials: corn starch composite fiber, the degradation cycle is shortened to 90 days, and the carbon footprint is reduced by 60%.
The treated non-woven filter element redefines the healthy humidification standard with “high-efficiency purification, long-term antibacterial, and green circulation”, becoming a smart choice for modern families to fight water pollution. From daily care to professional scenarios, it combines science and practicality to make humidified air purer and safer.
