Air fresheners are consumer products used in homes, or commercial products used in restrooms, that typically emit fragrance. There are many different methods and brands of air freshener. Some of the different types of air fresheners include sprays, candles, oils, gels, beads, and plug-ins. There are also solid and passive versions, which use ceramic material and water based ingredients – these combine and create a ‘multi-phasing’ effect which provides a constantly evolving fragrance. Some air fresheners have been known to have chemicals that provoke allergy and asthma symptoms raising argument about how safe it is to use. However, some air fresheners are VOC exempt, such as a passive, multi-phasing air freshener, that reduces the effects. Air freshening is not only limited to modern day sprays, air freshening also can involve the use of organic and everyday house hold items. Although air freshener is primarily used for odor elimination some people simply use air freshener for the pleasant odors they emit.
Fragrances have been used to mask odors since antiquity. A variety of compounds have been used over the past two millennia for their abilities to create pleasant aromas or eliminate unpleasant odors.
The first modern air freshener was introduced in 1948. Its function was based on a military technology for dispensing insecticides and adapted into a pressurized spray using a chlorofluorocarbon (CFC) propellant. The product delivered a fine mist of aroma compounds that would remain suspended in the air for an extended period of time. This type of product became the industry standard and air freshener sales experienced tremendous growth. In the 1950s, many companies began to add chemicals that counteract odors to their fragrance formulas. These chemicals, intended to neutralize or destroy odors, included unsaturated esters, pre-polymers, and long-chain aldehydes.
In the 1980s, the air freshener market shifted away from aerosols, due to concerns over the destruction of the ozone layer by chlorofluorocarbons (CFCs). Many other air freshener delivery methods have become popular since, including scented candles, reed diffusers, potpourri, and heat release products.
More recently, since 2015, a leading manufacturer has started looking at Vibrating Mesh Technology, as an effective, environmentally friendly and cost efficient method of dispensing fragrance.
Often misunderstood with piezo technology, the Vibrating Mesh Technology is a significant advantage over piezo based products that use wicks or liquid bottles, for example.
‘VMT’ (Vibrating Mesh Technology) air care technology is where a mesh/membrane, with 2,000 laser drilled holes, uses a piezoelectric element to vibrate at the foot of a reservoir, and thereby pressures out a mist of very fine droplets through the holes.
This technology is more efficient than having a vibrating piezoelectric element at the bottom of the reservoir, thereby a shorter coverage time is achieved – meaning fragrance for a room is dispensed more quickly and for longer, using less of the refill than in a piezo version.
