Sweet Air Vent Filter

Stop offensive odors from sewer and septic tank vent stacks

The Ultimate Solution for Residential and Commercial Vent Stack Odors

The Sweet Air™ Vent Stack Odor Eliminator offers an innovative, effective solution to one of the most common yet overlooked problems affecting residential and commercial properties: offensive odors from plumbing and septic vent stacks.

Using advanced activated carbon technology, this ingeniously designed system traps odors before they can escape into the surrounding environment, creating a more pleasant outdoor space and eliminating odors that drift through open windows.

How It Works

The Sweet Air™ system removes plumbing and septic odors through a straightforward process:

  • 1. Unpleasant odors rise from house or septic stack vents.
  • 2. Odors pass through the activated carbon chamber, which effectively scrubs and removes offensive elements.
  • 3. Clear, odor-free air leaves the system and disperses harmlessly.

  • Twist Top Cap: Allows for easy activated carbon maintenance
  • Vented Lid and Chamber: Ensures proper airflow while capturing odors
