Protecting occupants and air conditioning systems

One of the most overlooked vehicle filters is the Cabin Air Filter.
“Cabin filters are a relatively new innovation in passenger cars and many vehicle owners aren’t even aware their vehicles are fitted with one,” Ryco General Manager of Engineering and Innovation, Alastair Hampton, said.
“This can lead to these filters not being replaced as regularly as they should. In a time that the health and safety of many people has become so important, replacing an existing cabin filter with the best available on the market is a reasonably small investment to make.”
There are two things that are really important for a cabin filer to do – firstly they need to protect the vehicle’s occupants, making sure they are not exposed to airborne pollution whilst driving along the road, while also protecting them from pollens and particles that aggravate allergies.
Secondly, they also protect the HVAC system, which over time collects dirt and dust which when coupled with moisture and the cold HVAC system can see you growing mildew, resulting in flow issues and expensive maintenance.
Ryco says its upgraded MicroShield range of Cabin Filters are the most efficient and micron rated in the Australasian market and a must-fit for vehicle and workshop owners in this current climate. Whereas most cabin filters are rated to 2.5 micron, Ryco says its MicroShield sets the standard with a “staggering 0.3 micron” rating.
The N99 MicroShield cabin filter media are manufactured fine enough to also protect occupants from wood smoke for added protection if you live in bushfire prone areas, as well as human aerosols, which can carry viruses*.

“The Ryco MicroShield range of cabin filters are made from N99 medical grade media which provides both anti-viral and anti-bacterial properties. The MicroShield range of Cabin Filters from Ryco are 99.7 percent efficient and tested and compliant to ISO11155-2:2009 standards,” Alastair said.
The increased protection of the upgraded MicroShield range comes from an innovative three-layer system. The first layer is anti-viral with natural polyphenol extracts that eliminate viruses, bacteria and allergens. The second layer is activated carbon which is designed for odours and gas absorption. The third and last is medical grade polypropylene which is electrostatically charged, which collects more micro particles. Ryco says all MicroShield Cabin Filters are 100 percent safe and free from pollution.
Ryco explains that one of the many advantages of fitting a Ryco MicroShield Cabin Filter is that the anti-viral layer inhibits the survival of bacteria and viruses using a natural micronutrient called polyphenol.
This means not only does a Ryco Cabin Filter stop the bacteria and viruses from entering the car, it also destroys them at the same time – including serious diseases like Influenza A and H1N1/H3N3.
With research showing that a vehicle’s interior can contain over 10 times more pollutants that the outside air, Ryco is strongly urging all vehicle owners and automotive workshops to make a cabin filter check and/or replacement a priority.
When completed by a professional, a check or replacement takes only a matter of minutes on most vehicles.
When it comes to product design and development, Alistair said the Ryco MicroShield cabin filters now exceed the fit, sealing and filtration efficiency of their original equipment (OE) counterparts.
Ryco’s upgraded MicroShield Cabin Filters are available in over 120 part numbers, covering hundreds of popular vehicle models. More part numbers will be progressively available in the near future. The upgraded versions of MicroShield Cabin Filters will be denoted with an “M” on packaging as opposed to “MS.”
