Recommended to change it every yr tho...hope this helps mate theres loads on carbon filters and gettin ridof the smell of weed on here ...use the search and ul find loads of tips

The Commercial ones work better than I could have imagined.

Mine's a cheap one, 1m x 1m tent, agree with Bendbrewer that they work better than you'd of thought...well worth buying...and replacing yearly

I got a Phresh filter for my 2x2x5' tent, worked great for around 9 months and then some odor was leaking. I expected 1.5 years and decided to go with a cheap brand, since the Phresh had failed to last long. aegsupply over at ebay. Worked great for this grow and cost half of the Phresh filter.

I am going to refill this filter after it is used up and see how that goes. Yes, a good filter will remove almost all odor from the tent and surrounding area. Even if you are legal, it is a good idea because rippers will locate your grow by smell.
