"Furnace filters" in the UK

[AlanRM]

Hi  guys (and gals!). I would like to make 1-200  pine trees and have settled on this technique using layers of "furnace filters":

...See 2mins 50secs in, but to save everyone time, the material is described in this US video as blue fibre filters, available also in rolls. 

 

I think this is the stuff here (in half inch form - it's for OO/HO):

Clearly we have similar filters in the UK, perhaps under a different name or application. Many Google searches have led to heating and ventilation filters, fish pond filters, etc., but the choice is overwhelming. 

 

Does anyone have any ideas? 

 

Apologies if this has been covered before - I have seen many posts re tree fibres - but again, the choice is vast. It would be good just to find the UK equivalent (or even close) of the above if possible. 

 

Thanks in anticipation!

Hi all and an update.

 

I have also phoned a very friendly filter materials specialist who is popping a free sample of their "blue/white medium" in the post today. It certainly looks the equivalent of the US product, so fingers crossed.  

 

I'll report back on suitability when it arrives in case others are planning the same, but meantime if anyone has any other thoughts that would be very welcome.

 

I suspect various products would fit the bill but I'd like to stick as close as possible to the recommended formula  :-)

Nearest I could find was this stuff.

That's great - thanks! Personal experience beats everything. 

 

More shortly when I have the sample through the post. 

 

Cheers,
