Non-woven washable filter is the core filter component of evaporative humidifier. It is made of high-density synthetic fiber (polyester or polypropylene) through hot melt process. It has the characteristics of high-efficiency filtration, antibacterial and antibacterial, and reusable. With its core advantages of low cost, easy maintenance and long life, it has become an ideal choice for healthy humidification in home, office and commercial scenarios, especially for users who pay attention to economy and environmental protection.

Core functions and technical features

Multi-layer filtration and antibacterial design

Gradient density structure:

Outer layer coarse effect: intercept large particles of impurities in water (such as mud, rust, hair), pore size 50-100μm;

Inner layer fine: adsorb soluble substances such as calcium and magnesium ions and chlorine, and reduce scale and “white powder” pollution.

Antibacterial treatment: Silver ion or nano zinc oxide coating inhibits the growth of bacteria (such as Legionella) and mold in the water tank, with an antibacterial rate of ≥99%.

Efficient evaporation and durability

Uniform water absorption and diffusion: The capillary action of the fiber makes the water evenly distributed, and the evaporation efficiency reaches 400-800mL/h (depending on the ambient temperature and humidity);

Resistant to repeated washing: The material is tear-resistant and rub-resistant, supports machine washing or hand washing for more than 50 times, and has a lifespan of up to 2-3 years.

Environmental protection and energy-saving characteristics

Zero consumables design: No need for frequent replacement, the cost of a single cleaning is almost zero, and the annual average consumables cost is saved by 200 yuan+;

Recyclable materials: Polypropylene (PP) or degradable polyester (PLA), reducing 90% of plastic waste.

Core performance parameters

Five core advantages

Advantage dimensions User value

Economic and practical Repeatable washable design, with an average annual cost as low as 10 yuan, and the cost performance is far superior to disposable filter elements

Health protection Inhibit bacterial spread, eliminate “white fog” pollution, and sensitive people (infants, allergic people) can use it with confidence

Hard water adaptation Reduce scale deposition and extend the life of the humidifier by 30%-50%

Convenient maintenance Supports quick disassembly and cleaning (completed in 5 minutes), no professional skills required

Green and environmentally friendly Reduce plastic waste, some models use bio-based materials, and the natural degradation rate is ≥80%

Typical application scenarios

Daily household:

Winter dry heating room: relieve dry skin, throat discomfort, and prevent static electricity;

Households in hard water areas: reduce scale damage to humidifiers and reduce the frequency of equipment maintenance.

Office and business:

Office central air conditioning support: balance the humidity of open office areas and improve employee comfort;

Hotel rooms: silent operation, eliminate water tank odor, and improve the stay experience.

Special needs:

Flower greenhouse: stabilize humidity (60%-70% RH) to promote plant growth;

Musical instrument storage room: protect wooden musical instruments from drying and cracking.

Use and maintenance guide

Installation and activation

Plug and play: place the filter element vertically into the humidifier water tank to ensure complete immersion;

First use: soak in clean water for 10 minutes to activate the fiber water absorption performance.

Cleaning and maintenance

Regular cleaning: remove the filter element every week and rinse the surface impurities with clean water (avoid brushing);

Deep cleaning: soak in white vinegar solution (1:10) for 20 minutes every month to dissolve scale;

Dry storage: dry thoroughly when shut down to prevent moisture and mold.

Replacement reminder

Performance degradation: humidification efficiency is reduced by 40% or the filter element becomes obviously hard and discolored;

Material aging: fiber breakage or loss of elasticity affects the uniformity of water absorption.

Technological innovation and trend

Intelligent reminder design: some filter elements have built-in color-changing indicator strips, which automatically turn yellow to remind cleaning when scale or bacteria exceed the standard;

Photocatalytic upgrade: the surface is coated with TiO₂ photocatalyst layer, which decomposes organic matter under UV light to achieve self-cleaning;

Fully degradable material: corn starch-based non-woven fabric (PLA), which is completely degraded within 180 days, and the environmental protection is further improved.

The non-woven washable filter element reshapes the humidification experience with “economical and durable, healthy and safe, and green circulation”, becoming a smart choice to fight dryness in home and commercial scenarios. From low-cost maintenance to long-term protection, it solves complex problems with simple design, making healthy humidification within reach.
