Glad I checked this thread. DH and I quit smoking (me:almost 8 months ago, DH:still smokes a cigar now and then, *outside*) and I want that stank
outta here! I'ma check out those ozone thingamuhjiggies!
I've washed/had cleaned drapes, carpets, etc. but we have leather LR furniture and that smell is stubborn there, though the furniture was only in this house for a couple of months before the smoking inside stopped.
What I'd do as a temporary fix, just so you can tolerate being in the house for now, is to go to a local "head shop" (hush wmtire, snicker, I buy my vape/electronic cigarette juice there!) and purchase those HUGE incense sticks. They're about 30 inches long and will burn for 4 hours
I've used these trying to infuse a sandalwood scent into the house but it doesn't stay, or the cigarette smoke is stronger/more stubborn than the incense scent. But they're dang sure nice to use if I know company's comin'! Or just to enjoy a long evening at home without being reminded constantly of our smoking habit.
