Drugstores and other retailers are fully stocked with low-cost home fragrances, from room sprays to candles and wall plug-ins. Now, thanks to Air Esscentials and other such firms, there are options on the higher end: compact yet high-powered diffusers that will infuse scent throughout a room for hours or days at a time.
Examples include Aera, a $200 device the size of a paperback book that its parent company, Prolitec, says can perfume a room of up to 2,000 square feet, with fragrance levels adjustable through an app. Each fragrance capsule costs $50 and, according to Aera’s website, will last about 60 days if it is placed in “a 450-square-foot room, on an average setting running for 24 hours per day.”
Jeanette Wolfe, a holistic health educator, is a big fan of such devices and a big believer in the power of scent to increase energy and “drop you into a calm place,” as she put it.
She used to rely on old-fashioned methods to perfume her Victorian home in Princeton, N.J.: dried flowers and squares of muslin that were infused with essential oils and placed in the air vents. “But it wasn’t as strong or clear or efficient a scent as I wanted,” Ms. Wolfe said.
Now each floor of the house has its own fragrance dispersed by an AroMini, one of several styles of cold-air diffusers for the home made by AromaTech. According to the company, AroMini, a 12-inch-tall cylinder that costs $279, is strong enough to imbue fragrance in a 1,000-square-foot room. The essential oil or aroma oil refills cost $16 to $180, and last about a month.
Citrus, typically a combination of mandarin and bergamot, wafts through the first floor of Ms. Wolfe’s home, while frankincense and sandalwood perfume the bedrooms on the two upper levels. And to get rid of the “old house” smell of the basement, Ms. Wolfe favors “grounded scents” like evergreen, pine, mint and spearmint. “But I change them seasonally,” she said. “I’ll add spices during the holiday season. I’ll shift them if I’m having a dinner party. I’ll shift them depending on my mood.”
The home fragrance market is a $6.4 billion business at the retail level, according to a 2016 study by Kline, a market research and consulting firm in Parsippany, N.J. Using data from a Simmons national consumer…
