Glade's Ferns & Blossoms aerosol spray air freshener is my current favorite. It comes in a 9 oz spray can decorated with a picture of fern and small white blossoms; the deep-green top adds to the impression of forest, green leaves, and summer. In the midst of a snowy winter when I had first seen it at the store, this was very inviting. The fragrance did not disappoint me: very delicate, forest-fresh, slightly flowery. I loved it even more when I saw how great it works on different kinds of bad odors, eliminating them completely. Bathroom, cat's litterbox smells - just a shake of the can and a couple of brief sprays, and all you can smell is gentle blossoms. I was cooking fish once, and I hate how raw and half-cooked fish smells, so I used this aerosol; it did the same wonderful job, refreshing my whole kitchen and getting rid of the smell.
I have bought Glade Ferns & Blossoms many times since and I highly recommend it.
