When the nice folks at CritterZone Air Naturalizer called to ask if we would like to try their product, we jumped right on it. What is CritterZone you ask? It’s a compact and powerful device that eradicates pet and other household odors from the air. We pet owners are well aware of the never-ending battle with odors and allergens that come with owning a pet. The Air Naturalization process is a chemical-free, filterless, natured inspired technology. By producing a natural charged flow to the air, CritterZone gives indoor air the same energy the sun gives outdoor air to clean itself.
