Just by accident my regular go to air vent system.
works good and steady.
cant say too much about the exact modell but....
i recommend:
allways buy "pro line" filter instead of "eco line".
the "pro" version of filters are very efficient. Smells dissappear. Even smoke smell just leaves the room cuz these things kill smells sooo good.
ecoline doesnt do that.
ecoline kinda makes the weed smells less to very little....but there allways is a bit of smell.
but the pro versions....they just kill it.
totally worth the money.
