I just started painting figures recently but I've noticed something horrible since starting. The fumes from Tamiya Acrylics are causing me to develop a lot of phlegm after every time I use it. I tended to cough mounds of this stuff. I've tried using those masks that doctors use to combat it but it only helped a little. Even a small whiff is enough to cause small phlegm attacks. I work in my room with the window open and the door wide open with a fan on blowing directly at my direction to throw the fumes off and through the door. What would be the best mask to buy to combat this? Thanks.
