What type air filter for spraying alcohol/oil dyes

[Yukonrookie]

I got a question to you guys and gals out there that use an airbrush. What type filter do yous all use? I’m using mostly Fiebing Pro dye and Angelus Alcohol dye. I read that for solvent based dyes one should wear at least an A1, but there is acetone in some of them so I thought I best ask here. Any suggestions would be greatly appreciated. 
Thanks in advance.

I spray in a ventilated area in short bursts. The size of items I spray are not that big. Spraying a square foot of leather, in one go, is rare for me. 

If I needed a particle filter. It'd be a box fan with a hepa air conditioner filter taped to it. 

As for other things. You can stop by an Army surplus and buy an Israeli civilian, gas mask. Or a, "3M respirator half face" mask. Used regularly in automotive painting. 

But whatever filter you choose to breathe. You have to back it up with ventilation. You can't spray finish in an enclosed area and think you're not going to be breathing any in. No matter what you're wearing.

i built an extraction fan using 3 "squirrel cage"  fans found in microwaves that sit above stoves. these have the "fan" part completely separate from the motor. As Beehive suggested, you can use a box fan with a furnace filter. However, I am leery of this setup. The air movement generated by the fan causes all the fumes to pass thru the fan and the fan motor is right in the center of the stream. If there should happen to be a spark and you are using dyes with flammable components, bad thing may happen. 

Good luck

Box fan motors are brushless. It's an electromagnetic type deal. That's why the motor can run for years. Oiling the two bushings, decades. 

If you're spraying enough, to where the air is saturated to the point of spark ignition. Steps need to be made. 

I spray in my kitchen. Next to an open window. For me to fill the room enough. That the stove pilot light ignites the air. Forgive the pun, but I'd be burning through big money in paint. Using more then a tiny airbrush spraying it.

I use what the MSDS sheet tells me to use. you can get them online for any product made.

 One other word of safety for those in cold climates right now. If you set up some type of ventilation system in your house you also need to open a window or door to allow fresh air to enter at the same rate as its vented.  What can happen if you don't is a negative pressure situation could happen. when that does air is pulled into the house from any place possible like your chimney or heater vent which can fill your house with carbon monoxide. Carbon monoxide is deadly, invisible, and odorless.

All great and important suggestions. Thanks a bunch guys. Lots to think about before making my exact plan of attack
