LitterGuard's Bipolar Ion Technology targets BOTH fundamental types of litter box odor:
For Poop Odors, Ionic Oxidation breaks apart odor molecules (VOCs) in the air into odorless, harmless compounds.
For Pee Odors, Ionic Precipitation grabs ammonia molecules and pulls them out of your breathing zone where they safely dissipate.
Odors are microscopic gases. Using HEPA is like trying to stop mosquitos with a chain-link fence.
LitterGuard targets gases directly, working continuously with any litter box setup.
