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.
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 Layer
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, Air born 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 s4 HVAC system.
Why Our Filters Are Better
Standard filter the air only passes through 2 mm thin material in an old style “W shaped pleated” Audi s4 air conditioner filter.
Most of these filters only remove Dust and larger debris some filters have a small amount of carbon added and are an improvement ,but the air still only passes straight through a 2 mm thin layer of material before entering your vehicle.
So you may find our Audi s4 Cabin Air Filters different in overall thickness to your old cabin air filter.
It is just a superior design to your old 2 mm thin cabin air pollen filter and will fit where the old style Filter was installed.
Your new premium Audi s4 Cabin Air pollen Filter is designed to be replaced yearly as the micro pores of the activated carbon Trap & absorb the dangerous contaminates and become less effective over time.
Also replacing the Audi s4 air-conditioner filter yearly helps keep the air-conditioner working at peak performance.
