Hey everyone.
Was just wondering...
Ive just put in my carbon filter for odour and to pull air into my room from outside now the hole ive got is 100mm with some ducting in it would it be better to have 2 holes or just the one what do you reckon the room is 2.4m x 1.2m ?????????????
The carbon filter is up high and the fresh air hole is down low so it creates a vacume and doesnt let the smelly air out of the hole....
