Luber-finer's Extreme Clean HD Filters trap contaminants, allergens and odors. The air filters use carbon activation to remove up to 98 percent of bacteria, dust, pollen, mold spores and exhaust gases from incoming air, according to the company. Baking soda in the media minimizes unpleasant nuisance odors that can distract drivers. The Extreme Clean HD is available in 16 parts numbers covering major over-the-road trucks.
