I love diffusers, my youngest daughter loves scented candles and my oldest daughter, who has two cats, loves it all! Room scents should be subtle but pleasing. They can evoke memories and instill tranquility. Overwhelming scents can be disturbing and leave people wondering if you’re hiding the smell of a dead animal under the couch. Home scents come in many forms and varieties. You might not realize it, but many public spaces are scented. Retail stores, gyms and spas, hotels, banks, and even food retailers are attaching scent nebulizers to their HVACs (Heating, Ventilation and Air Conditioning). Private homes and apartments can use nebulizers that connect cold-air diffusers to their HVACs. Scent technology is on the rise. Many businesses have custom scents developed as part of their branding identity.
