Subaru Outback Cabin air filter triple-layer carbon cabin filter, Australian Made. Part number CAFA42SO
How Our Filters Work

As the polluted air is forced through 1000s of tiny pores constantly swirling and changing direction, it’s 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; the carbons microscopic pores absorb noxious odours, gases, and chemicals. The cleaned fresh air then exits the Subaru Outback cabin filter into your Vehicles interior. Unlike a standard filter, the air only passes through a 2 mm thin material

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 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 Subaru Outback air conditioner. We are providing the best possible protection from pollution entering your Subaru Outback 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” Subaru Outback cabin air pollen filter.
  • The contaminated air travels through the entire 20mm of 3 carbon layers in our Cabin air filter, giving vastly improved chemical absorption and filtration.
  • The filter is also designed to provide a better seal around the edges of filter and filter housing to reduce contaminates  bypassing the cabin air filter.
Replace Yearly

Your new premium Subaru Outback Cabin Air pollen filter is designed to be replaced yearly, as the micropores of the activated carbon absorb the dangerous contaminates and become less effective over time. Furthermore, replacing the cabin air filter keeps your Air-conditioner operating at peak performance.
