How It Works

The air filter uses activated carbon technology to continuously circulate and purify the air inside your refrigerator ā€” neutralizing odors from foods like fish, leftovers, and produce before they spread or affect flavor.

  • Activated Carbon Core: Uses a dense carbon matrix to adsorb odor molecules and gases on contact.
  • Continuous Air Circulation: Works with your fridge's fan to pull air through the filter repeatedly, 24/7.
  • Adsorption Technology: Traps contaminants at a molecular level rather than just masking smells.
  • Passive Filtration: Requires no maintenance between replacementsā€”install, and it works automatically.

What This Filter Removes

Our certified filtration system targets and removes a wide range of harmful contaminants and odors.

  • Food Odors: Neutralize strong smells from fish, leftovers, onions, and other pungent foods.
  • Ethylene Gas: Absorbs the natural gas emitted by ripening produce that speeds up spoilage
  • Airborne Bacteria: Captures and reduces bacteria circulating in the air inside your fridge.
  • Mold Spores: Filters out mold spores before they can settle and grow on stored food
  • Volatile Organic Compounds (VOCs): Remove harmful chemical compounds that can affect food quality.
  • Cross-Contamination Particles: Prevents flavor and odor transfer between different food items.

When to Replace Your Refrigerator Air Filter
