I ordered on behalf of my husband who never used net sales. I have been using it regularly, but because I did not sell nearby, I found you, I was at your place, correspondence was early and it was saved.

Mighty micron filter is good for prevention of dirt.

I chose by cospa to increase the life of the micro filter. I think it's good.

Used in combination with micro filter. The paper filter will be dirty black in one day, so it will be effective. I first used it to increase the life of the microfilter, but I think it is also helping to improve the dust collection effect

How are they used before and after the yellow filter?

I use it on a regular filter.
The melting of the iron material with rust and oil is usually dirty because the color is attached to the smoke.
By doubling this paper filter it will usually prevent contamination of the filter.
Another, 20% price is also cheap and saved.
I bought all three of the pre - filters.

It seems that the other two types are better if welding work is done. As a dust main prefilter.

Because it is cheap and there are so many, it is saved. Because the company does not buy it, I am often asking.

It is hard to install so it is hard. Dust and dust can be taken well. It is a thankful item.
It is used during the cleaning work in the warehouse.

The powder is always scattered inside the warehouse because of the handling product "powder bag", and it can not be filtered with general mask of nonwoven fabric during cleaning work. Furthermore, using this "prefilter" increases the life of this filter.
