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 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 Toyota Corolla 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” Toyota Corolla 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 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 Toyota Corolla Cabin Air pollen filter is designed to be replaced yearly. Unfortunately, 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. Additionally replacing the Toyota Corolla air-conditioner filter yearly helps keep the air-conditioner working at peak performance.
