it works pretty nicely in cars cause its such a small area and it covers up the smell pretty quick. as for a room, it doesn't work as effectively. if you need to cover the smell up real quick a spray around the door will work for short term, but it dissipates quickly and smells like ozium + weed instead of just ozium. five minutes and good airflow plus ozium works fine for a room though
Get yourself some incense for inside the house. Smoke a cigarette in your car (only if you smoke of couse)
Ozium is pretty badass, like it'll make it reek of ozium, but it's a good smell, and it'll cover up anything, you could have a rotting body in your room and no one would know
Ozium works the best, have tried everything, but only stick with the original scent, got a can of the new car smell and it smells like liquid ass
