Furnace Filter Trees.

[tetters]

The furnace filter is commonly known as "Hogs Hair" type of filter. It either comes in blue or green depending on the manufacturer. The product I purchased was called True Blue. Although apparently you can get the same type of filter called NatruaAire (or something like it) at Wally World and it is green in colour. I have not tried the wally world stuff, but since you are going to paint your filter brown the colour really does not matter.

I think for your Copper Beech, you'd be best served by Super Trees from Scenic Express. The furnace filter is best suited to conifer trees.
