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 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 Subaru Impreza HVAC system.

Why Our Filters Are Better

With a standard pleated filter the air only passes through a single 2mm thin material layer .With our filter the contaminated air travels through the entire 20 mm of 3 Carbon filter material layers, giving vastly improved chemical absorption and air filtration.

Replace Yearly

Your new premium Subaru Impreza Cabin Air pollen Filter is designed to be replaced yearly. 

Unfortunately, like most good things, activated carbon eventually stops working. That’s because the carbon’s surface has become saturated with all the chemicals & impurities that it has adsorbed. When that happens, your cabin air no longer gets cleaned and the smells will return.

Also replacing the Subaru Impreza air-conditioner filter yearly helps keep the air-conditioner working at peak performance.
