Please do not take this as "Scary" Stuff it is just Facts on what I consider to be important for my Family and just thought I would update and share it and it is hopefully of some interest - Dave
I posted recently on the subject of the Internal Pollen Filters and this has again been mentioned in the Motoring Press (Autobild / Heidelberg University) here again this week. The recommendation after the Tests is to install the Carbon Type
Filter which apparently removes around 92% of the NO2 pollutions which the Std Paper
Filter does not. The problem is that the NO2 Nitrogen Oxide Gas when inside the vehicle can attack the Mucous Membranes, cause Eye Irritation, shortness of breath, coughing etc..
What I have been doing in the past is that as soon as a Diesel or Petrol Smell enters the QQ inside I Switch over to Internal Air Circulation :
I read that the Nissan QQ
Filter #272774-BU0A was one of these Filters (as mentioned before). Well after digging in on the details it is
NOT and the facts are wrong !. I visited our Dealer on the weekend and spoke with the Service Mgr. who confirmed this and I told him I was concerned due to the reports and the fact that Nissan
DO NOT install these Filters at manufacture only the Std Paper Type. On assessing the problem we found a compatible Active Carbon
Filter Nissan #27277-4BU0P in the Dealers Store (250x180x35) and this was installed in 5 mins FOC and the Std
Filter#272774-BU0A was removed.
The
Filter is basically a 4 Layer Construction :
1st Layer - stops the biggest dirt particles.
2nd Layer - Activated Carbon Layer stops the Gases NO2, Pollen, Soot etc…
3rd Layer - Microfibre Electrostatic
Filter cleans the smallest particles from the air.
4th Layer – is the Carrier which stabilizes the Layers to give a perfect function.
I have looked on the Web and found information on for example
MANN Filters, the Std is #CU25 003 and the
Carbon #FP25 003 which suits the QQ and might well be worth a read especially if Family members Old or Young suffer from Breathing / Lung problems etc…
There are other Suppliers for example : Bosch, Denso, Mahle, Hummel, Valeo etc…
