Cabin Air Filters

The cabin air filter is responsible for cleaning outside air entering the vehicle. Because up to 100,000 litres of air can be blown into the vehicle’s interior in less than an hour, it can easily become clogged with debris. Unfortunately, a blocked cabin filter will not be effective, resulting in a below-par heating and cooling system, and causing the air inside the vehicle to become more polluted than the air outside up to six times more. Similarly, bacteria and fungi can accumulate in the filter, leading to unpleasant smells in the cabin. Fitting a high-performance cabin filter, such as Delphi, is essential in eliminating these harmful pollutants and odours, safeguarding both you and the air conditioning (A/C) system.  

High-performance media

All our cabin air filters use a high-performance, non-woven fabric to eliminate dust, pollen, bacteria and exhaust particles, amongst others. The specially designed filter fabric contains up to five individual layers, removing near 100 percent of harmful pollutants.

Enhanced protection 

Over time moisture can build up in the filter and become a feeding ground for bacteria and mould. This can then  spread into the lines of the HVAC system, where it emits unpleasant odours. For the ultimate protection from this and other pollutants, we also offer a range of carbon activated filters. Our carbon activated filters feature the same high quality, non-woven fabric as our particle filters, with the addition of a layer of activated carbon. Sandwiched between two layers of fleece, this highly effective technology removes more pollutants than standard filters, and expels nasty gases and smells too.

Resource Highlights

In this article, you will learn more about our technical tips on what to do and not to do for Compressors. 


Oil balance the compressor according to the instructions provided with the compressor.

An oil balance will ensure the compressor has the correct amount of compressor lubricant for proper compressor operation.


Leave protective shipping cap in place until assembly of refrigerant lines.

Prevent loss of lubricant and contamination or unit, and absorption of moisture by PAG lubricant. (PAG readily absorbs moisture from the atmosphere.)


Store compressors in the shipping box until ready for installation.

Damage to the clutch, electrical terminals and pressure switches will result if the compressor is handled and/or stored improperly.


Use correct torque control tools:

  • To attach refrigerant lines at the compressor.
  • When installing compressor brackets.
  • When securing the compressor to the engine.  Excessive torque may strip threads in the compressor housing. Under torque will result in loose, damages, or a noisy compressor.


Hand start bolts securing the suction discharge hose set to the compressor. This is a critical requirement.

This will prevent the steel bolt from stripping the threads or cross threading in the aluminum compressor housing.

Do Not 

Set the compressor on either end, stack or subject them to shock at any time. Keep the compressor in a horizontal position.  

This Damage to the clutch, electrical terminals and pressure switches will result if assemblies are handled and/or stored improperly.

Do Not 

Lubricate seal washers prior to attaching refrigerant lines to the compressor. 

Seal washer design does not require lubrication to affect a leak free joint.


Replace protective shipping cap on suspect or defective compressors.

Uncapped compressors are subject to leak lubricant, become damaged, or absorb moisture, making subsequent analysis difficult or impossible for the part supplier.
