after i moved into my new house i came about a problem,,my windows are the type that crank out sideways and it would be hard to make something to vent outside yet leave the window secure and dry,,so after some thought and a trip to Lowe's,here's what i came up with
i took a 4" elbow and mounted it into the center of a 5 gallon bucket lid,cut 1 1/4 holes (4) around the edges take four respirator cartriges and mount one in each hole(must be airtight)...i put about 2" of kitty litter in the 5 gallon bucket,,used some panty hose ,cut off one leg and tie a knot in it,,cut off the other and secure it to the bottom of the 4"elbow(so that the air enters the bucket un restricted),stretch the waist part over the bucket top and then snap on the lid..the air will enter the elbow into the bucket,the kitty litter helps trap paint matter(overspray) as well as any "damp" air,the air then is force through the panty hose covered holes which act as a pre filter for the respirator cartridge,then through the cartridge and back into the room as cleaned air,,after all we use a respirator to keep the organic compounds (vapors) out of our lungs,so in conclusion,i just ran it backwards and filtered the air BEFORE it gets released back into the room,,,,i sprayed with enamels and laquers all afternoon and noticed NO smell,but i still wouldn't smoke or have an open flame around the bucket,even though it's sealed and the air has been filtered to the outside of the bucket,it may contain some residual elements......what's everyone think? am i onto something here?
