I only use this
I also use the white filter together.
As it is expendable item to use every day, it is more glad if you can make it cheaper

I think that it is personally highest. I think that it is cheap if you consider the suction of iron powder, dust etc. with a little expensive price.

I can not think of an unhappy place. It is economical to use 3 ~ 5 days in one piece.

Because dust is flying, it is something our company needs.
Because accessories can also be purchased separately, I am very appreciative.

A three layer structure with a gap layer between two trapping layers. Each collection layer is about 1/3 the thickness of conventional products, achieving collection efficiency higher than conventional hyper micron filters. It is said that. I chose it in COSPA.

Although I tried to use it several times, although the filter is black, but breathing can also be made uncomfortable and exchange is easy so it is easy to use
