"The fragrance/oils is very concentrated and you really only need a little bit (one spray for a 500 sq. ft. room) otherwise it will become VERY overpowering and force you out of the house. As pleasant as the aroma is (and it IS pleasant), using too much will result in an opposite sought after effect. Spray ONE spray at a time, letting it diffuse into the room for a few minutes before spraying again.
This is a great alternative to aerosol/spray cans full of artificially fragranced garbage. And since each spray IS so concentrated, it lasts quite a while when used conservatively."
