Carbon Filter Size - Armoire?

I very impulsively bought a HID for my next grow. I then doubled down and bought a large wardrobe off craigslist. I have nowhere in my condo to put this thing. Assuming can get past this:

The box is roughly 6 ft high, 4 ft wide, and 20 inches or so deep. Planning on running the 400w cooltube.

I really want to drop a carbon filter in this and it is really why I bought it, but I do not see dimensions of how large these fan filter combos are on the web. The back is plywood and where I plan to put the hole.

What size and model fan/filter combo would work well with this set up? Thinking of ducting the cooltube separately with a booster fan.

http://sog.co.nz/articles_ventilation.htm read that has some useful info

6 cubic meters (6m3) 1 cubic meter equals 1,000 litres of air, so this room contains 6,000 litres of air, in order to remove the total volume of air in this room you will need a fan with a capacity of at least 120 lps (litres per second), hotter or more humid rooms may require greater air exchange.

i think your about 1.2m3 so that would be 1200L. so whats that 24Lps (could be wrong i just woke up)

Appreciate the feedback, but you lost me on the metric system. I can figure out the cubic feet per minute/ air exchange. What I'm trying to figure out is how to get one of these things in the box.

Ok....Can anyone suggest one of these for my box? Are these generic ones comprable to CAN?

Go here, enter your dimensions and go by that. It doesn't need to be a Phresh filter but it gives you an idea.

Ok. I've got one. I'm scratching my head on how to install this. It's heavy and I have no shelves. Suggestions?

For the 122 views and to close the thread. Although it was not booming with suggestions hopefully I will get some good karma because not much came up on the search.

Using an antique wardrobe can be problematic, but I bought it for $100. The wood alone for the size would have cost more to build...plus it looks like furniture, which really would have been a hassle to duplicate. If you can find one with no shelves, the right dimensions, not too ugly and for a decent price jump on it. I had been stalking craigslist for 2 months to find it.

I ended up with the 4in can 2600 fan filter combo, which fits horizontally at the top of the box. It's rated at 123 cfm, which is less than I would like, but the box is only 45 cu feet, so it should be adequate. Relatively quiet if the doors are closed.

There is an immovable wardrobe bar at the top I plan on hanging my light from. So I didn't want fan and filter swinging from that. I wanted the fan filter somewhat parallel to the bar and behind it, so I could get a clear line for light hangers and not lose anymore verticle room.

For the fan:
I bought some 1/4 in machine screws w/bolts and fender washers and connected the fan to the middle of the box on a semi flimsy verticle support beam in the middle of the box. The wood backing was just too thin and I didn't want to risk anchoring it even though I would have more room to connect the fan to the filter. For insurance, I got some huge zipties and I will zip the fan bracket to the wardrobe bar just in case.

For the filter:
No room to run ducting in between this and the fan, so it is a direct connect to the flange. This was a bit of a bitch put together. I got some plumbers tape a.k.a. plumbers strap a.k.a metal strapping. It's a galvanized steel 3/4 of inch wide and thin to bend. It's designed to suspend large pipes. It's perforated with holes perfect for 1/4 in screws. So I looped it around both sides of the filter and screwed it to another semi flimsy support beam at the top back of the box. Bolt and washer on the back. I will also zip tie this to the bar for insurance.

Next, I just slid the filter over the fan. This took a little angling, but it held. Then boom duct taped it.
