Humidifier Sticks
Humidifier sticks, also known as evaporative humidifier cartridges or filters, are components used in evaporative humidifiers to add moisture to the air. They are typically made of a porous material designed to absorb water and facilitate evaporation.
Material
Common materials include:
- Cellulose: The most prevalent material, often wood pulp-based, offering good absorbency and evaporation rates.
- Paper: Similar to cellulose, often used in disposable filters.
- Antimicrobial Treated Materials: Some sticks incorporate antimicrobial agents to inhibit the growth of mold, mildew, and bacteria.
- Honeycomb Paper: A structured paper design increasing surface area for improved evaporation.
Purpose
The primary purpose of humidifier sticks is to increase humidity levels in a room or enclosed space. This is beneficial for:
- Relieving Dryness: Counteracting the effects of dry air, particularly during winter heating seasons.
- Easing Respiratory Issues: Soothing dry nasal passages, throats, and skin.
- Protecting Wood Furniture: Preventing cracking and warping of wood items.
- Maintaining Comfortable Indoor Environment: Creating a more pleasant atmosphere.
Function
Humidifier sticks function through the principle of evaporation. Water is drawn up through the porous material via capillary action. A fan then blows air across the saturated stick, causing the water to evaporate into the air, increasing humidity.
Usage Scenarios
- Bedrooms: Maintaining comfortable humidity levels for better sleep.
- Living Rooms: Improving air quality and preventing dryness.
- Offices: Creating a more comfortable working environment.
- Nurseries: Providing a soothing atmosphere for infants.
- Homes with Heating Systems: Counteracting the drying effects of furnaces and other heating sources.
Common Types
- Disposable Cartridges: Single-use filters that are replaced regularly (typically every 1-3 months).
- Washable Filters: Reusable filters that require periodic cleaning to prevent buildup of mineral deposits and bacteria.
- Antimicrobial Filters: Contain antimicrobial agents to inhibit the growth of mold, mildew, and bacteria.
- Honeycomb Filters: Structured filters with increased surface area for improved evaporation.
- Wicking Filters: Designed to draw water up efficiently for optimal evaporation.
Humidifier sticks are not explicitly defined within the provided reference material. However, based on potential material composition and use, the following HS codes may be relevant:
- 3825900100: Residual products of the chemical or allied industries, not elsewhere specified or included; municipal waste; sewage sludge; other wastes specified in note 6 to this chapter: Other. This code covers residual products from chemical industries. If the humidifier sticks are byproducts of a chemical process, this could apply. The total tax rate is 55.0%, comprising a 0.0% base tariff and a 25.0% additional tariff, increasing to 30.0% after April 2, 2025.
- 3825610000: Residual products of the chemical or allied industries, not elsewhere specified or included; municipal waste; sewage sludge; other wastes specified in note 6 to this chapter: Other wastes from the chemical or allied industries: Mainly containing organic constituents. If the sticks are chemical waste primarily composed of organic materials, this HS code is applicable. The total tax rate is 55.0%, with a 0.0% base tariff and a 25.0% additional tariff, rising to 30.0% after April 2, 2025.
- 4823901000: Other paper, paperboard, cellulose wadding and webs of cellulose fibers, cut to size or shape; other articles of paper pulp, paper, paperboard, cellulose wadding or webs of cellulose fibers: Other: Of paper pulp. If the humidifier sticks are made of paper pulp, this code could be relevant. The total tax rate is 55.0%, consisting of a 0.0% base tariff and a 25.0% additional tariff, increasing to 30.0% after April 2, 2025.
- 4823907000: Other paper, paperboard, cellulose wadding and webs of cellulose fibers, cut to size or shape; other articles of paper pulp, paper, paperboard, cellulose wadding or webs of cellulose fibers: Other: Other: Other: Of cellulose wadding. If the sticks are made of cellulose wadding, this HS code may apply. The total tax rate is 55.0%, with a 0.0% base tariff and a 25.0% additional tariff, increasing to 30.0% after April 2, 2025.
