i think what a lot of people dont realize is that when your exhausting to an attic or outside you need to go to the attic to tell if it realy smells or not , and also ,
when you live in the stench you yourself dont smell it after even a short ammount of time
i run filters and masking agents and when ppl come to visit me they claim to smell it at the street (15 ft away from the house) , and i DONT exhaust to the attic or outside at all
please for everyone here and your own safety dont assume everything is fine simply because you yourself dont smell it
peace
