Protecting HVAC systems with a Ryco cabin air filter

One of the most overlooked truck filters is the cabin air filter. “Cabin filters are a relatively new innovation and many truck owners aren’t even aware if their vehicles are fitted with one,” said Alastair Hampton, Ryco’s general manager of engineering and innovation.

“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 filter to do: Firstly they need to protect the cabin’s occupants, making sure they are not exposed to airborne pollution whilst driving along the road. It’s also protecting them from pollens and particles that aggravate allergies. Secondly, they protect the HVAC system which, over time, collects dirt and dust, coupled with moisture and the cold. Without the HVAC system you end up growing mildew, resulting in flow issues and expensive maintenance.

There’s never been a more important time to have a truck’s cabin filter working at its peak level of performance. Ryco’s 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, MicroShield sets the standard with a staggering 0.3 micron.

“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 per cent efficient and tested and compliant to ISO11155-2:2009 standards,” Hampton added.

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 odour and gas absorption. The third and last is medical grade polypropylene that’s electrostatically charged, which collects more micro particles. All MicroShield cabin filters are 100 per cent safe and free from pollution.

One of the many advantages of fitting a Ryco MicroShield cabin filter is the anti-viral layer inhibits the survival of bacteria and viruses using a natural micronutrient called polyphenol.  The benefit is that not only does a Ryco cabin filter stop the bacteria and viruses from entering the truck’s cabin, it also destroys them at the same time.  This includes serious diseases like Influenza A and H1N1/H3N3.

With research showing that a cabin’s interior can contain over 10 times more pollutants than the outside air, Ryco is strongly urging all truck owners and 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, Hampton commented, “The Ryco MicroShield cabin filters now exceed the fit, sealing and filtration efficiency of their original equipment (OE) counterparts. To do this, we concentrated on precisely matching the OE filter housings using our own Melbourne based R&D team and technology like 3D scanning plus we focussed on improving the cabin air design and construction. The results have been impressive.”

Ryco has a wide range of commercial vehicle cabin filter applications. 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 the packaging as opposed to “MS”. You can download the cabin filter range flyer by scanning the QR Code.
