Quick Navigation:
Modern plug-in air fresheners are sophisticated electronic devices designed for safety and efficiency. To get the most out of your home scenting system, it is vital to understand the technical specifications and maintenance requirements that ensure consistent performance without compromising household safety.
Quality plug-ins like the Air Wick Scented Oil Warmer utilize high-grade polypropylene (PP) for their shells. This material is chosen for its high chemical resistance and flame-retardant properties (often V-0 rated). Internal components typically feature ceramic heating elements or positive temperature coefficient (PTC) resistors, which safely regulate temperatures between 131°F and 149°F. The wicks are usually constructed from sintered porous polymer or polyolefin, engineered for high capillary action to ensure the oil reaches the heater at a steady rate.

This often occurs if the reservoir is empty or if dust has accumulated inside the heater. Ensure the wick is saturated and the vents are clean. If the smell persists, the ceramic element may have reached the end of its 24-36 month lifespan.
