I just moved into my small studio apartment 3 months ago, and usually its just me smoking. I use a sploof, towel the door, turn on the exuast fan above the stove and blow the smoke right into it. I use ozium spray and make as little smoke as possible. I just moved in after all. I recently had a few friends over and one thing led to another and smoke was everywhere in the apartment. I have had no complaints but I know someone fer sure smelled that. I mean how could you not. Usually it is just me taking a few hits every now and then and no one can smell it, but if i decide to have a guest over occasionally I want to have the odor taken care of. I don't wanna annoy other tenants with a marijuana smell again. I was thinking If i got a air purifier that it might do the trick. I researched it a tiny bit and the ones with HEPA filters and Ionizers are said to help with smoke. I was wondering in anyone has tried it and how it has worked for them?
