Most plug diffuser work by heating scented oils. A single-use plug in air freshener or refillable model can provide a convenient short-term fragrance fix. These fragrance products are suitable for scenting one or more small rooms, such as bathrooms or closets. However, if you want to spread a scent throughout your home or another space.
Air fresheners that plug into outlets typically feature porous polymers that act as wicks. The electricity powers a warmer that heats scented gels or oils to enhance the scent throw or spread of fragrance. Most plug in air fresheners draw approximately 4 watts of power.
Single-use plug ins are intended for disposal once the scent fades. These designs are more wasteful than models that have refillable oil tanks or are compatible with replacement scent cartridges.
Some plug diffuser systems make it possible to adjust scent strength. One of the leading brands has a dial that you can turn to adjust the release of fragrance. These controls are not as precise as those of a smart diffuser system, though.
The customization options for a digital diffuser system allow for complete control and increased efficiency. In addition to being able to set the strength of scent released through a diffuser used in either method, you can also time the release of scent. These diffusers draw minimal levels of power and do not release scent unless specified in the settings.
The best way to determine whether air fresheners that plug in meet your odor modification needs is to consider the square footage of the area you plan to scent. If you want to spread fragrance in more than one room or rooms larger than small bathrooms or closets, a scenting diffuser will likely end up being more economical over time than plug in models.
