Are they really proprietary??
No, it’s based on duct size/collar diameter typically. 4", 6", 8" etc.
Dork at the grow store tried to make me think it’s complicated (shakes fist)
Don’t listen to them, the pro’s are all here
You can even refill most good ones but damn messy trust me for the money you save the dust and mess you’re cleaning for days is rarely worth it
Refill the carbon filter? It’s a fabric that fits over a tube, right? How would one refill that?
Maybe some confusion.
The carbon filter is the big heavy filter.
The white filter is just a pre-filter to catch the “big” stuff. Those would need to be sized to the actual carbon filter and would be a little more brand specific. However, they can be washed.
Refilling the carbon filter is actually replacing the carbon inside the big heavy filter.
Oh @Matthew420 then yes I am confused. Not knowing where to star my questions what can be replaced and waist is disposable (you have to buy a new one)?
It’s all a bit disposable.
In most cases, at some point, the filters will need to be replaced. You can wash and dry the white fabric pre-filter.
The big heavy filter, that the white filter slips over, can be replaced or just the carbon in it replaced. For under $60 for a new filter, I personally won’t be refilling.
Some also have “reversible” end caps. This means you can swap ends of the big filter (3 or 4 screws on each end). This allows airflow through a part of the filter that was least used.
Lol my filter is nearly $300 but rated for 600cfm 89lb’s 2 1/2" carbon bed it has refill option 50kg bag of carbon is about $60 but very messy. Looking into new one this summer will need to be working it’s best with PK going
Haha, fancy! I think I paid $59 for mine (just the filter).
Lol they have come down in price some over the years and early ones lasted years were repurposed from body shops etc… I love mine but won’t need so large a filter again any time soon. Was using for spaces far larger more plants than now
LOL! Made my own bought a 7 inch fine mesh strainer for $8 at Walmart bought 5 pounds of carbon on ebay $15 fits perfect in tent vent hole holds a pound $23 total with 4 refills
