SEASONAL MOISTURE & EVAPORATOR PADS
Humidifier & Dehumidifier Filters
Evaporative humidifier water panels and wick filters prevent mineral scale buildup and maintain healthy 40–50% relative indoor humidity during dry winter heating seasons.
Typical Lifespan: 1 to 2 seasons (replace annually at start of winter heating season)
Price Range: $10 – $25 per pad
Evaluation Standard: ASHRAE 52.2 & AHAM CADR
Essential Buyer Selection Criteria for Humidifier Pads
- Anti-Microbial Aluminum Mesh vs. Paper Wicks: Whole-house units use porous aluminum mesh with ceramic coating; tabletop humidifiers use replaceable cellulose wicks.
- Seasonal Replacement: Mineral crusting significantly degrades evaporation efficiency. Replace at the start of every heating season (or twice for hard water).
- OEM Sizing Match: Water panels must fit tight against the scale control insert to prevent water leaks and dry air bypass.
