Toilet Bowl Deodorants & Odor Counteractants are available here.
How to choose a block deodorant:
- Para Block Deodorants - Air-activated, freshen the air and eliminate undesirable odors. Made from paradichlorobenzene saturated with liquid deodorants.
- Enzymatic Para Block Deodorants - Combines standard para blocks with the addition of beneficial bacteria. The bacteria release enzymes that consume the odor's source, effectively and permanently eliminating odors.
