I deal with this all of the time myself. There isn’t anything that can be done. I just do extra deep cleaning, got an air purifier and a cool mist humidifier. I’m asthmatic so the smoke bothers me so damn much but the humidifier helps, especially when I put a few drops of essential oil in it. I hate the smell of smoke so much I can’t express it enough. It literally makes me sick. But there’s nothing we can do but try to get by financially and rent a house at some point in the future. Try to put your clothes in the room that smells the least like it and even spray essential oils in there every day
