I was in a bar awhile ago,(shocking right?), and i noticed that the bathroom smelled really strongly of fresh laundry. I walked over to a white plastic fixture on the wall way up high and started messin with it. The bar owner had put a thumb tack in the wall and it was just hanging on it. I opened it up and there was an areosol can inside of it with a controler that would dispense a spray at whatever time increment chosen. I hung it back on the wall and went out for another drink and googled it. The thing cost like fifty bucks and then the aerosol replacements were twelve. The replacements last two months on the lowest setting and thats what i have mine on. You can also get a cheaper dispenser for around thirty bucks and get some more nose friendly scents from yankee candle for a couple more bucks, if you got a couple more bucks id go with a yankee scent if its in your house and your smelling it all the time. Otherwise they can get pretty strong if its in your bedroom for example. My veg area was stinking up my whole house and one of these little guys took care of that with no carbon filter. My bloom has a carbon filter but i put one near it in a huge room and nothing but fresh laundry scent even with me smoking in there all the time. These things mask odor great. Needless to say when i left the bar that night i bought my stupidest friend a tequila shot and he stole the one from the guys...and the girls bathroom. Problem solved for five bucks.
