Audi A3 Cabin air filter triple-layer carbon cabin filter, Australian Made. Part number CAFA226A3
How Our Filters Work

As the air moves through 1000s of tiny pores constantly swirling and changing direction depositing microscopic particles along the way, Though over 20 mm thickness of 3 progressively finer activated carbon filtering layers. Particles stick to the carbons rough surface and noxious odours, gases and chemicals are absorbed by the carbons microscopic pores.

1st Layer

Our Cabin Air Filter has a 1st 15 mm thick layer of activated carbon filter sponge. This layer traps allergy-causing particles such as pollen, dust, mites, fungus spores, pet hair, organic and inorganic material and is the first layer of noxious odour and pollution absorption. 

2nd and 3rd Layers

Second and third layers of progressively finer carbon filter material over 4 mm thick. Traps and absorbs as much as possible dangerous microscopic particles such as Bacteria, Airborne heavy metals, harmful gases, diesel exhaust particulates, chemicals, and ozone. Supported by our low allergy custom-made acrylic base designed for your air conditioner. Providing the best possible protection from pollution entering your Audi A3 HVAC system.

Why Our Filters Are Better
  • Standard cabin air filters the contaminated air only passes through 2 mm thin material in an old-style “W shaped pleated” Audi A3 cabin air pollen filter.
  • Our Cabin air filter the contaminated air travels through the entire 20 mm of 3 carbon layers giving vastly improved chemical absorption and filtration.
  • The Audi A3 pollen filter is also designed to provide a better seal around the edges of the filter and filter housing to reduce contaminates bypassing the cabin air filter.
Replace Yearly

Your new premium Audi A3 Cabin Air pollen filter is designed to be replaced yearly as the micropores of the activated carbon Trap & absorb the dangerous contaminates and become less effective over time. Also replacing the Audi A3 air-conditioner filter yearly helps keep the air-conditioner working at peak performance.
