the house candle smells are everywhere

My roommate Sharon makes candles. Her main supplier is fundraisers for schools. So she makes hundreds of candles at a time plus a whole range of scents. The smell in our home is horrible when she is in the school season. The conflicting scents provide me a headache. I tried trapping Sharon in 1 room with her scents. Unfortunately I have a central heating plus air system. The scents waft right into the air duct plus the Heating plus Air Conditioning plan ensures that all rooms in the home get the smell. I want to block off the air duct in Sharon’s room but she begged me not to. The candle making process is a hot 1 plus she wants a/c. In the Winter not having any heating would kind of odor too. What she suggested is a ductless mini split for her room. The air duct could be clogged off plus she would still have Heating plus Air Conditioning. The ductless mini split would deliver heating plus air plus only affect her room. That would be a genuinely pricey thing to do though. I am thinking more along the lines of an whole-home air purifier. I could install an air purification plan that cleans the smells from the air quality as she makes the candles. It is a quarter of the cost plus I guess I will make our roommate spend our money the cost too. She is the whole reason I would need an air cleaner anyway. She is not going to love that though. She genuinely would prefer me to buy her a ductless mini split complete with a smart thermostat.
