Audi A4 Cabin air filter triple-layer carbon cabin filter, Australian Made. Part number CAFA225A4.
How Our Filters Work
As the air moves through 1000’s 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 Layers
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 dangerous microscopic particles such as Bacteria, Airborne heavy metals, harmful gases, diesel exhaust particulates, chemicals, and ozone as much as possible. Supported by our low allergy custom-made acrylic base designed for your air conditioner. Providing the best possible protection from pollution entering your Audi A4 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 A4 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 A4 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 A4 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 A4 air-conditioner filter yearly helps keep the air-conditioner working at peak performance.
