Carbon filter replacement

I have come to a point where my carbon filter no longer is adequate to cover the skunk. The filter is a year and a half old and has run near constantly during that time. I have a dust filter on it and regularly wipe it out.

Would it be better to purchase a brand new filter or just replace the carbon in the old filter? Replacing the carbon would cost almost the same as a new filter but would obviously be less harmful to the earth.

I have researched ozone generators and decided that is not the option for me as I exhaust into an outside window well and do not have the option to exhaust into a separate room.

There will be two ONA buckets placed in the room as an additional measure to the carbon filter.

The question remains: to buy a new unit, or replace the carbon in the old one? Thanks for your input.

New carbon from pet store: 80$
New filter from hydro store: $220

I just replaced one of mine and it works like a charm again

What size filter do you have? How much carbon does it take? I can find new carbon filters on eBay with free shipping for $80.

Don't put ona gel inside your room. It messes up the smell of the weed I've argued this with friends and we have tested it. Use It outside the room. Ozone generators are the same thing, not good for the plants, use them outside the room to eliminate any odor that has creeped into garage or house or wherever . As far as your question about the carbon filter.. If it's a big one.. I would much rather reuse it and not have to deal with throwing it away and bringing in a new one. Good luck

Thanks for the heads up on the ONA gel. I wondered that since one time I used dryer sheets to transport bud and it destroyed the smell and taste of the product.

I've heard if you use an air compressor and air wand and blow out filter from inside. It will work like new again.

I have not had luck refilling and getting the same performing. I would buy a new one.

2 at a time, as my scrubber uses just under 2 each rebuild. total materials for building my scrubber was about 100.00 (actually about 80.00 iirc), then the charcoal. ill swap to coconut next time I rebuild my scrubber. I have it matted to an 8" 750cfm fan at 100% 24/7.

ive since moved the fan to outside the tent, not on the scrubber

ill swap to coconut next time I rebuild my scrubber.

What do you mean by this? Putting coco in your filter?

coconut husks as the carbon medium. supposed to last a bit longer and absorb/filter smells better than charcoal.

New phresh. Period. Security is not something to mess with. Just my 2¢

All comments and pictures posted by the entity known as packetloss314 are completely fiction and at times outright lies. All content was copied from the internet and all statements are from the mind of a lunatic

Don't fuck around with security, buy a new one and fix your old one later if you want.

New is the way to go ime. Saving a few bucks on odor control, not smart.

Alright so I just picked up this one off of Ebay: http://www.ebay.com/itm/6-x-40-CARBON-FILTER-HUGE-REVERSIBLE-VIRGIN-CHARCOAL-AIR-inch-GROW-ROOMS-/121096316726?pt=US_Hydroponics&hash=item1c31e72736. The sales rep at htg supply said it would be enough to filter an 12x5x7 room with 2400 watts. What do you guys think?

I grabbed this of of botanical.com as a guideline to determine my needs:

Calculating By Room Volume

You will find many calculations on the web for sizing a fan for ventilating indoor gardens; however, what many of these calculations fail to take into consideration is the friction loss on carbon filters and increased temperatures from HID lights. So here's my calculation method which you can use as a guide for sizing an exhaust fan for a growing area (keep in mind that this calculation will give you the lowest required CFM (Cubic feet of air per minute) required to ventilate the indoor garden.)

Step 1: Room Volume
First the volume of the room needs to be calculated. To calculate multiply length x width x height of growing area e.g. A room that is 8' x 8' x 8' will have a volume of 512 cubic feet.

Step 2: CFM Required
Your extraction fan should be able to adequately exchange the air in an indoor garden once every three minutes. Therefore, 512 cubic feet / 3 minutes = 171 CFM. This will be the absolute minimum CFM for exchanging the air in an indoor garden.

Step 3: Additional factors
Unfortunately, the minimum CFM needed to ventilate a indoor garden is never quite that simple. Once the grower has calculated the minimum CFM required for their indoor garden the following additional factors need to be considered:

Number of HID lights — add 5% per air cooled light or 10-15% per non-air cooled light.

CO2: add 5% for rooms with CO2 enrichment

Filters: if a carbon filter is to be used with the exhaust system then add 20%

Ambient temperature: for hot climates (such as Southern California) add 25%, for hot and humid climates (such as Florida) add up to 40%.

An Example
In our 8' x 8' room we have 2 x 1000w air cooled lights, and we plan to use a carbon filter. We also plan to use CO2 in this room. The ambient temperature is 90 °F (32°C), however, we will be using air from another room that is air-conditioned. Here's the minimum required CFM to ventilate room:

1) Calculate the CFM required for room (see above.)

2) Add 10% (for 2 air cooled lights.)

3) Add 5% of original CFM calculation (For CO2.)

4) Add 20% of original CFM calculation for Carbon Filter.

5) Air is coming from air-conditioned room so no need to add any other percentages.

6) CFM = (171 CFM) + (171CFM x 10%) + (171 CFM x 5%) + (171CFM x 20%) + ( 0 )= 231 CFM.

This is the absolute minimum CFM required to ventilate your room.

The next step might seem to match the closest fan to this CFM. However, for this example I'd choose a six inch fan with a CFM of around 400 or more, and a 6 inch carbon filter to match. The extra CFMs may seem a bit excessive (calculations on most indoor gardening websites would recommend a 4" fan and a 4" carbon filter) but it's always better to over-spec since we need to compensate for air resistance in ducting too.

Also, as we are using a carbon filter we will need to match the fan with the filter so that the fan that will neatly fit onto the filter.

If all the variables are kept the same and we changed the room size from 8' x 8' to a 12' x 12' then the minimum required CFM would be 519 CFM.

So for myself: CFM= (140) + (140X20%) + (140X%20) = 196 CFM.

The carbon filter I purchased has a max efficiency scrubbing CFM of 424 which indicates a max efficiency exhausting CFM of 212.

In combination with my active intake and outtake this filter should be sufficient to use as an exhaust.
