Best Carbon Filter

What is the best carbon filter available to buy?

From what I have read it seems like Mountain Air and Phresh are the most efficient and longest lasting filters out. I think these both use RC-48 Australian Carbon supposed to be really good if not the best carbon available.

I know it is hard to say unless you have had personal experience so that is what I am looking for.

What brand filter is the best at removing smells from even the smelliest strains?

Here is a link to my particular filter: http://www.ebay.com/itm/4-Activated-Carbon-Filter-Hydroponic-18-tall-can-/290566904261?pt=LH_DefaultDomain_0&hash=item43a72319c5#ht_3585wt_971

My filter, even oversized for my cfm and with a 2" thick carbon layer, doesnt seem like it will cut it in the later flowering since I get just a slight smell already only 2-3 weeks into flower it is only going to get worse. It isnt reaking but there is a VERY slight smell already and I dont want to get deep into flowering and be like UHHH NOW WHAT?!?!. Id like to have a nice carbon filter ready in case I need to swap it out and I want this one to be quality.

Thanks

Do you say "bump" when you don't have the answer but want to find out too?

I hear Mountain Air Carbon Filters are the best. I use a hydrohut goblin but I'll need a new unit for the next run.

just get one several sizes larger than you need and set the fan on medium through it...and it should last a "long" time..

There are many great carbon filters on the martket today, Phat, Can, mountain air to name a few. Go with a reputable company, but id say the bigger issue with correctly using carbon filters would be to pair them up with a fan in their CFM range. Even the absolute BEST carbon filter monay can buy will perform poorly if too much or too little air moves thru it. Just something to think about :)

I agree..even for a 4 x 8 rectangle.. friend swears by Canfilter 100 and an 8 inch fan on a speed controller seems overkill..but zero exterior
odor. Tents and black and white plastic type rooms can be difficult.
Odor just seems to creep around.

DIY filters work really well too.


I do have a small 4 inch Mountain Air .. i also have carbon ready to refill it ..i have yet to refill it..3 years later. I never believe any claims of how long filters last..but with sometimes high heat and 24hr operation.it had worked in a small 3 x 4 area or over 3 years

I use a Dutch breeze carbon filter.Been using it for a long time and still the same carbon,works great,even with the Cheese strains.As far as the Phresh filters are concerned,I have read a few things about it not lasting but three months on the original carbon.I agree with spadedNfaded on the proper #s.

Can Filters.................pick the size you think you need, then bump up to the next size. Nothing sucks more then buying an entire setup and 7 weeks into 12/12 you realize you should have gone with the next size up. Ask me how I know. :D

As stated above, make sure you are running the correct amount of cfm thru the filter. Match the correct size fan and consider it done.

Bueno,
There are a lot of good filters out there. I am using Mt. Air and Phresh which use the same carbon. The Mt. Air is housed in stainless steel, and the Phresh is in aluminum. I think both are good. I'll probably replace the mtn airs with phresh because of price, and lighter weight.

Others are correct in saying that getting the right air flow for your filter is necessary. Best to get a bigger filter than recommended for your sq. footage. Running air thru the filter too fast won't remove odors properly. Best to, with higher capacity filter than needed, run fan about 20% slower than capacity. Filter lasts longer that way.

Also, changing pre-filter after a year is good, but I think thoroughly vacuuming the filter itself every 2-3 months extends life of filter. I vacuum the pre-filter every couple of months.

Here's a helpful link. http://www.westcoastgrowers.com/carbonfilters.htm Note "indicative cfm."
 
can all the way... only thing I ever see in the shops anyways.

I run a Can 66 for flower with 6"s&p and a 2600 for drying/test room.

they last about a year run 24/7 I'd say... maybe less like 10 months...

bought about 4 or 5 I guess...

I've tried the phresh filter, didn't like it. It didn't last nearly as long as my Can, it'll last atleast a year.

Another factor to consider when using a carbon filter is the fact that when the humidity is above 75% the carbon is not as effective at scrubbing the stank. You have to keep humidity under control, I like to keep my rh around 50%-60%. Balancing between when the stomata on the leafs are open and breathing(VPD, vapor pressure differential) and still keeping the pm at bay is a tricky act.

Good luck, Peace
