I. Cleaning Cycles and Methods for Different Wet-Fiber Materials

The wet-fiber mat is the core component of a humidifier, commonly made from cellulose-based, metal alloy, or synthetic polymer materials. 

Different materials require distinct cleaning methods and cycles. Proper maintenance prevents performance degradation and damage.

Recommended Cleaning Cycles

• Cellulose-based pads: Highly absorbent but prone to microbial growth. Inspect every 1-2 weeks and perform thorough cleaning monthly.

  In high-humidity or dusty environments, clean weekly.

• Metal alloy pads: Highly corrosion-resistant but susceptible to mineral buildup. Clean every 2-4 weeks. Increase frequency in hard

  water conditions.

• Synthetic polymer wet film: Offers good stain resistance, typically requiring cleaning every 3-4 weeks. Avoid chemical corrosion.

Cleaning Method Steps

• Power Off and Remove Wet Film: First turn off the humidifier's power supply. Carefully remove the wet film component, avoiding

  excessive force that could cause deformation.

• Gentle Rinse: Rinse the surface with running lukewarm water (not exceeding 40°C) to remove dust and debris. Avoid high-pressure

  water jets on fibrous materials to prevent damage.

• Deep cleaning: Soak in a neutral detergent (e.g., diluted soap solution) for 10-15 minutes, then gently scrub stubborn stains with a

  soft brush. Note: Metal wet membranes can be wiped with a soft cloth; synthetic materials must not be cleaned with strong acidic

  or alkaline detergents.

• Drying and Reinstallation: After cleaning, place in a shaded area to air dry naturally. Do not expose to direct sunlight or use a dryer.

  Ensure complete dryness before reinstalling to prevent mold growth.

II. Scale Prevention and Removal Techniques

Scale primarily forms from mineral deposits (e.g., calcium, magnesium) in water, clogging humidifier pores and reducing efficiency. 

Long-term buildup may damage water pumps and heating elements.

Preventative Measures

• Use softened or distilled water: In hard water areas, install a water softener or use distilled water directly to minimize mineral

  buildup at the source.

• Regularly drain and clean: Empty the water tank and base weekly to prevent stagnant water scale formation. Enable automatic

  drainage if supported by the device.

• Control usage frequency: Adjust humidification intensity during dry seasons and avoid continuous high-load operation.

Cleaning Methods

• Natural Dissolution Method: Soak the humidifier membrane in a white vinegar and water solution (1:3 ratio) for 30 minutes.

  The acetic acid softens scale deposits, which can then be gently brushed away with a soft brush.

• Specialized Cleaner: Use a commercially available scale remover (select an eco-friendly option). Dilute according to instructions,

  soak the components, and rinse thoroughly with clean water afterward to prevent residue buildup.

• Mechanical Removal: For heavy deposits, carefully scrape with a plastic scraper. Never use metal tools to prevent scratching the

  wet membrane surface.

III. Bacterial Growth Control Measures

The humid environment of wet membranes fosters bacterial and fungal growth, compromising air quality and potentially causing 

equipment odors or malfunctions.

Daily Control Strategies

• Regular Disinfection: Every 2 weeks, spray the humidifier surface with food-grade hydrogen peroxide or diluted alcohol solution

  (concentration ≤70%). Let sit for 10 minutes before rinsing. Avoid bleach to prevent material corrosion.

• Maintain Dryness: When the humidifier is off, empty the water tank and wipe the interior. Remove the humidifier membrane and

  air-dry it. For long-term storage, disassemble and store in a well-ventilated area.

• Environmental Management: Ensure the operating environment is well-ventilated. Avoid placing the unit in corners with high temperatures

  and humidity to minimize external contamination sources.

Deep Cleaning

• If odors or visible mold spots appear, perform immediate thorough disinfection: First rinse with clean water, then soak in disinfectant

  for 20 minutes. Finally, clean crevices with a soft brush. After completion, briefly air-dry in sunlight (only for UV-resistant materials),

  but avoid prolonged exposure.

IV. Water Distribution System Blockage Resolution

The water distribution system ensures even water dispersion across the humidification membrane. Blockages cause uneven humidification, 

increased noise, or even equipment shutdown.

Common Blockage Causes

• Accumulation of impurities or scale in water.

• Prolonged lack of cleaning leading to algae or microbial growth.

• Entry of external debris (e.g., dust, fibers).

Troubleshooting Steps

• Inspection and Diagnosis: First observe whether water flow from the distribution nozzles is uneven or completely blocked.

  If abnormalities are detected, immediately disconnect power for inspection.

• Clearing Blockages:

Use a fine needle or soft-bristle brush to clear nozzles, handling gently to avoid damaging internal components.

For severe blockages, disassemble the distribution pipe and flush with warm water in reverse direction, or soak in cleaning solution to 

dissolve impurities.

• Preventive Measures: Install a filter at the water tank inlet and replace it regularly. Inspect the distribution system monthly to ensure

  unobstructed water flow.

Conclusion

Regular maintenance of your wet-film humidifier not only effectively addresses issues like scale buildup, bacteria, and clogging but also 

significantly extends equipment lifespan and reduces unnecessary repair costs. Remember, prevention is better than cure—simple daily 

cleaning and proper usage habits are key to lowering maintenance costs. This illustrated guide aims to help you easily master practical 

techniques. For further questions, consult your equipment manual or seek professional advice. Take action now to keep your humidifier 

performing like new, enhancing comfort and health in your daily life!
