I'd like to preface this thread by saying I do NOT use aerosols, those cone thingies, plug-ins, etc. I'm instead looking for safe or alternative ways to help freshen up my living space. Whether it is rat safe air freshners (don't know that that exists) or how to DIY my own ratty safe air freshner. I live in Minnesota, USA and it's starting to get too cold to open windows and as it turns out, my apartment's air is quite still and stagnant. We have high ceilings, no ceiling fans, etc. I can only place so many fans too lol. Any ideas? Any help is greatly appreciated!
