The Ultimate Odour Control Thread

This could change the way we filter or don't

Just now I was just reading about this cutting-edge technology that really destroys odor in a room VS what we capture in our filters. They completely sold out right now according to them but I wonder. who would know possibly about & personally what size would I need to do a 10' x 11' with this room with this product? It's Nanotech I would appreciate any input on this.

"Science at the nanoscale.
Developed over two decades by research scientists, PECO is an innovative technology that utilizes free radicals—the same radicals used to kill cancer cells—to oxidize pollutants. By using nanotechnology, PECO is able to destroy pollutants 1000 times smaller than traditional HEPA filters (0.1 nanometers versus 300 nanometers"

I am not an advertiser nor will ever be one I hope posting this link won't get me in trouble here
the company is "molekule"
I currently have 10 types of herbs in my grow closet with 4 plants will see what happens this is just a test, if it doesnt help or doesnt work then ill just build a carbon filter.

I think I already know the answer to my question but being new to scrubbers figured I’d get confirmation.

In the morning when the lights have been out all night the room I have my tent smells like carbon, no smell of the grow.

As the day progresses especially near lights out it’s almost as if the filter stops working. It’s not horrible but I can smell the grow.

I have no way of venting outside so the filter vents in the room. A huge garage that is not air tight so I do get fresh air.

I’m assuming it’s the humidity causing this as the day progresses and the longer the lights are on the higher the humidity the less effective my filter gets. Am i wrong to assume this?

It’s not a top of the line filter. eBay brand we can say. It’s a 4” and my fan runs 190CFM in a 3x3 tent.

I use a 4 inch inline fan which is rated at 190 cfm attached to a 195cfm mountain air filter. i find that sometimes odor is a slight issue depending on strain etc. Anyways i am thinking of getting a 6 inch filter which is 326 cfm and using a reducer for the 4 inch fan. this way i will have more than enough filter for whatever i am growing. does anyone know if this will work? Sorry if this was already asked.

Always go with the biggest filter you can for the space. The fan will work fine on bigger filters.

Too large a fan for the space can just as easily work against you. In my industry (industrial air handling) we use math to determine ach and cfm. Too large a fan means too many cfm and not enough "dwell time" for the odors in the carbon.

10"X24" Phresh Filter on a 6", Slowed, inline fan proves to knock out any and all odor. Phresh Filters WORK!!!
Excellent! the more time the odors sit in the carbon the more effective it is. Slowing the fan down seems counter intuitive at first, but it turns out that the opposite is true.

There are many odor absorption medias out there. Carbon is just one of them. Potassium permanganate and coconut shell are another two that work just as well, better in some applications.

According to General Carbon..coal based G34X8 works best for cannabis odor.

trying to decide between these 2 filters!

I can easily run either way, the two small 6in. ones in each of my tents, then pull air out and then out the room, or I can leave the inside the tents open and blow all air through the 8in! I have fan plenty powerful enough to handle either or all.

price is about the same, my main goal is 100% zero smell!Screenshot_2019-01-14-06-20-43.png

You need 10 ach. You also don't want too many cfm as it will only pull the odors too quickly through the carbon. See my post above on how to work out mathematically how many cfm you need. More isn't better.
