My roommate does wood working for a career. He not only makes wood furniture, but he repairs older pieces. He will frequently sand and varnish various wood pieces, but my roommate does not have a workshop though. So basically all the sanding and varnishing happens in my dwelling. The dust from the sanding is just awful. The dust gets in my eyes, nose and throat. I also regularly have a headache and sinus complications. With the varnish, my head kills me after an hour of soaking it in. I actually need to get my roommate a workspace or get some form of air purification system for the dwelling. Opening the windows and the door don’t do that much in terms of ventilation. I have actually tried running my Heating and A/C appliance to remove the complications, however it only does a little bit. I guess adding an air purification system to the furnace and AC appliance will actually helps things out significantly. There should be less dust and varnish with using an air purification system. I don’t really believe all my complications will go away, however it could help matters out quite a bit. I could even get a quality air purification system if the one in my Heating and A/C appliance doesn’t work. They make these air quality appliances greater and could be set up right where my roommate is currently working. I could also ban him from working in the dwelling. My roommate is such a sweet guy and he actually does some nice work as well. I don’t want him to feel like he can’t be inside with the furnace and AC appliance.
