Carbotron Carbon Pleated Filters — for Powerful Odor Control
Activated carbon pleated air filters engineered to adsorb odorous gas molecules from your home's air — cooking smells, smoke, pet odors, VOCs, and more. Today's tightly-sealed energy-efficient homes trap these gases inside; Carbotron filters capture them at the source.
Our Odor-Ex carbon pleated line (also stocked as the Glasfloss Carbotron) uses millions of tiny carbon openings to leave behind clean, fresh-smelling air. Made in the USA.
How Activated Carbon Filters Work
Different from particle filtration — carbon captures gases at the molecular level
Standard pleated filters trap particles like dust, pollen, and pet dander. They can't capture gases — which is why your home can still smell after the filter is changed.
Carbotron carbon pleated filters add a layer of activated carbon with millions of microscopic pores. Each pore is sized to chemically adsorb (bind to) odor-causing gas molecules as they pass through. Cooking smells, cigarette smoke, pet odors, paint fumes, VOCs — they all stick to the carbon and never make it back into your air.
The result: MERV 8 particle filtration plus active gas-phase odor removal, all in one filter that drops into the same slot as your standard pleated.
