We've discovered an effective treatment for the "smell of life" as I like to refer to it.
Any place where someone lives, cooks, eats, showers, sleeps, and all other of life's essentials will acquire lingering scents. The "smell of life".
Using scents to cover up other scents doesn't really eliminate the "smell of life". So a friend of ours loaned us an "ozonator". It's an electronic device that produces ozone, a naturally occurring gas that absorbs odours and humidity as well. Large amounts of ozone are produced during thunderstorms, for example, and is in part, the reason why things smell fresh after a thunderstorm. So we tried it.
Wow! It works. You have to remove all pets and yourself from the room being treated. Small rooms need only about 1/2 hour. Larger rooms need up to 2 hours. But after it's done, the air (and upholstery, bedding, etc) smells very fresh and clean. It virtually eliminates the "smell of life". It's surprisingly good. It also kills mold and mildew. And repels insects.
Highly recommended.
