Need a CHEAP Carbon Filter and duct fan...

CanFan filters work the best for high humidity conditions. They are the only brand that uses a particular mix of carbon to combat ruthless humidity. I don't know the science behind it, but I am their customer for life. After trying a number of brands that claim the same results I'm going to leave it to the filter pros!

are any of the filters refillable?
How about a fan speed controller...What's the best one, and do they quiet down the fan significantly? I need silence!

Just set can filter in floor, put a fan on top and set in corner. If you want to cut down on fan noise, run u a pirce of duct about 3 ft long off the fan. I've found that this will greatly reduce fan noise as most of it comes out the exhaust side

So, does a speed controller help to quiet it down??? I can set 1 4" fan on "low" ans still pull enough cfm for my room.
Will the low setting quiet the fan significantly? Or will you hear the whine/hum of the fan motor from stressing the fan by turning down the voltage?

you need a variac for speed control to be guaranteed not to produce hum.

Variant is a brand? Or style? Never bought a speed controller before.
Any links you can send.my way?

Panasonic makes the quietest fans. This 240 cfm is like 1.4 sones. http://www.westsidewholesale.com/whisper-line-240-cfm-6-duct-in-line-fan.html Best energy use to cfm ratio I have found. You can hear it if you sit next to it. My oscillating fan is louder. You need to vent the room or introduce CO2 the plants will use it up and replace it with oxygen and die if the room is sealed. The cfm will drop depending on the resistance of the filter you put on it. Can you open the ceiling and repair it when you leave?

Has anyone tryed those "Ozone" lights? ive never tryed them with growing weed but i smoke cigs in my garage and it does take the smell away fast and you only have to leave it on for 20-30 mins a day and at the price of 12 bucks really its not a bad deal... but does it work with weed plant smell? idk but as far as testing cigs and turbo car exhaust the light does clean up the smell pretty nicely.

No, Variac was a brand. Now it has become a common name for a variable tarnsformer (in much the same way as many vacuum cleaners are now commonly called 'hoovers')
The difference is, variacs (sorry, variable transformers) slow fan speed by reducing voltage without affecting Hertz or amps (which is what causes the hum). This is a very simple explanation as I have little understanding (I am no electrician). All I know is, it works, and most other methods that work by simply applying a resistive load don't without causing extra hum, no matter how pretty the packaging.
This is a link to one but I'm in the UK.

How about this?

That was the one I was planning on purchasing.

Either that one, or this...

it's just a matter of time before you get mold if the air is not circulating at night, you might be good for a few grow but's yeah ,... that's my take on it, what is your humidity before the light goes on?

The CanFan filters, as with most reputable brand carbon filters are not designed for an easy refill. I have heard of folks doing it, but I've never smell tested the results. I have used them more than a year at a time, 24/7, in high heat and high humidity. I have never even needed to throw one away actually, I've just gifted them out when it's time for an upgrade. Other brands I've tried in the same conditions lacked complete control and typically lost a significant amount of efficiency within six months.
The CanFan filters come in a lot of sizes. They are manufactured in BC. I've used both of these, (and most of their other models):
CanFan 150
156lbs (123 lbs of carbon)!
scrubbing: 2520 cfm
exhaust: 1260 cfm
flange sizes: 10,12,14"
contact .1 sec

CanFan 66
44lbs (31lbs of carbon)!
scrubbing: 824 cfm
exhaust: 412
flange sizes: 6,8,10"

Someone said Panasonic are the quietest? I've never tried them but you can sound proof any fan with anything from rubber buffers to a sound proof box!

Happy Exhausting (hope its breezier than that sounds)!

No. Your pretty little ladies request you silence your fans without sacrificing airflow. If you set a speed controller on a 4" fan to low you will probably be pulling about as many cfms as an induction fan. You will sacrifice weight. What you are willing to spend now to comfort your nerves so you can blast that fan will be well worth it in the future!!!! Good luck, hope you find what you need to make both you and your lovely ladies smile.

So the odorsok worked?! I'm really impressed! Have you tried it with a larger environment? You said you have had problems with carbon filters and humidity. I've had the same experience with most all the lighter weight filter brands, but have been completely satisfied with CanFan. The only thing I would change is their weight. Are the odorsok's essentially weightless?

Zank you for your input!

Didn't see you were using a closet. I recommend this://www.canfilters.com/canfilters_33.html

OK guys, I bought a couple things earlier today. Bought a fan/filter combo and a speed controller.

I think this stuff should be more than good enough for my 2x3x7ft closet. At the most there's 3 plants in there at any given time, and everything is 12/12 from seed.
According to my math, I only need 30 cfm or so. LOL I just want silence from the fan. The auction says something about a reverse impeller for quiter noise. Never heard such a thing, so I'm sure it's some sort of gimic.
