How Halo works
From plug-in to fresh air, here is what happens.
Plug it in
Place Halo near the litter box, in an outlet or wall-mounted above it.
Press once
Tap the button. A soft light confirms the ions are flowing.
Ions go to work
Negative ions spread through the room and bond with odor molecules.
Odor breaks down
Ammonia and sulfur compounds break apart, and dust and dander settle out of the air.
Leave it running
Halo runs 24/7 on about a watt. Rinse the dust screen now and then.

Built for litter box chemistry
Halo targets the two things behind litter smell and keeps the air around the box clean.
Neutralize odor
Negative ions bond with ammonia and sulfur odor molecules and break them apart, so the smell loses its bite.
Key Benefits
Settle dust and dander
The same ions charge airborne dust, hair and dander so it drops out of the air you breathe.
