Does A Carbon Filter Remove 100% Smell

Can't speak for CAN filters, they do seem a bit more legit than most. Generally the more they weigh, they better they work. Those CAN's are heavy as balls.

I have been VERY happy with the ipower filters off amazon. I have a 4" and a 6" and they both eliminate 100% of the odor. For the money i don't believe they can be beat.

ive had my 4" for over a year and like 40% of that time it was in my office just filtering the smoky air in there 24/7. My 6" i just got.

I'm using the 6" Apollo and it works like a charm. I figure iPower and Apollo are manufactured at the same plant in China.. If they're not the same company altogether.
I was going to shell out triple the $ for a phresh filter but decided to try and save a few bucks. Glad I did.

I'll say it for the 50th time or so. Dont pay a premium for carbon filters. If you want a pretty enclosure then buy one for the enclosure and when the carbon runs its life out go by bulk carbon and refill it. If you dont care if it looks pretty just buy carbon and make your own. Literally thats all these filter guys do is take activated carbon and stuff it in a sheet metal enclosure and charge a 5x premium.

That's what's nice about this forum.. You can't trust a review on any website that sells anything these days. I've never needed a carbon scrubber til recently bc all of the growing I did was outdoors.

I have far more money than time, so I'll pass.

Going into my 5th week of flower. 2x2x4 tent. 4in inline fan, 4in carbon filter...because of the negative pressure 24/7...you can't smell a thing. Even right up against it. Opening the tent is a diff story :bigjoint: just do your research on the cfm of the inline fan vs the filter. They have to be properly purchased so that it works correctly

@haze010 , does it really make it a difference whether you pull or push air through the filter? In order to free up space, I would much rather have only the fan inside, pulling air and pushing it through a short duct to a filter on top of the tent. But apparently it is not how most people do it around here, and I can´t figure why other than having to wash the prefilter more often.

*chuckle* It would take the average person under 10 minutes, but okay.
i can click "one click order" in under 10 seconds... what's your point? 10 mins assuming i already have everything i need right in front of me. There are plenty of things i would diy but this is not one of them. I diy things that don't exist in the world not things i can easily buy especially if they aren't even expensive.

There is more wear put on the fan when you push and less air moved also there is no way to vent it out of the room. You want to vent that air out of the room so your ambients don't climb throughout the day and you can't really do that if you are blowing through the filter.

Well, I´m running CXBs + QBs on a 4x4 tent and it is never really hot around there parts, so I´m not much concerned with temperature. And I would understand that the air blown into the filter would be pushed out through the charcoal so yes, I would be venting it out. The fan is running on its slow setting, so I´m not much concerned about wear and tear (even if it were at high or whatever).

Pulling air is always more effective, just physics. When you "push" the air you essentially have to create air compression. When you "pull" the air you are creating a pressure difference which aids in sucking more air through. Think of it like trying to push a rope through a hole vs pulling it through a hole. Most that use an inline fan have just the filter inside the tent with the fan a fair amount down the ducting.

Makes sense. But still, I´m running a 420CFM fan on a 8x20 filter (rated for about 600CFM), which seem way plenty for a 4x4 tent. So am I wrong in thinking there should be no problem, since I´m pushing a rope through a large hole?

Your nose is always the answer to the question if its effective enough, you just asked which was more effective. If space is that much of an issue why not just have both outside the tent? Have the filter first then the fan and let your nose be the air tester... just make sure that ducting is airtight.

Yes, I will pay attention to the odor, but did not want to experiment if there was some reason why it was inevitably bound to fail. I probably should have worded my question a bit differently.

I´ll keep in mind your idea of having both outside, but to reduce the noise and vibration I will try to hang the fan inside first, pushing air to an outside filter, and hopefully my duct would hold up. Thanks!

Bull. The phresh is better than cheap knock offs. The cheap ones last 6 months to a year and phresh I get 1-2 years out of.

I quit buying filters and just refill them. I also bake my carbon to recharge it.

I also oversize my filter. I run a 8 inch filter on a 4 inch fan.

There is a difference in the types of carbon used.

Coal based is not as good as coconut based. Its not.

I've bought several types and tested.

There is a reason for price difference. You get what you pay for and not all carbon is equal.
