does not cover-up or mask odors like typical fragrances, sprays and plug-ins. 
Its special blend of highly absorbent natural minerals attracts, absorbs and 
eliminates odors, leaving the air indoors as fresh as the air outside.
       Forever Fresh Odor Eliminator is non-toxic, non allergenic, child safe, pet safe 
and biodegradable. Once you use Forever Fresh Odor Eliminator in areas such 
as your closets, bathrooms, kitchen, baby room, basement, storage areas, 
exercise room, work room or any other area of your home, you’ll wonder how 
you ever got along without it!
Simply remove the Forever Fresh Odor Eliminator pouch from its plastic wrap and
place it near the source of the odor. One Forever Fresh pouch will cover an
average sized room, approximately 150 square feet, and last up to 3 months. 
Severe odors may require additional pouches.

Forever fresh doesn't cover-up odors, it ELIMINATES them. 
Just place in your bird room (out of reach of birds) and forever fresh does the rest!
Odors are transported through the air by molecules, which have a positive ion 
charge.  Forever fresh has a negative ion charge, which acts like a magnet, and
attracts, absorbs and ELIMINATES odors such as pet odors, toxic gases, skunk odor, 
bacteria, molds, mildew, fungus, smoke, and other odors that it comes in contact with.
