What Size Carbon Filter Do I Need?

What size carbon filter for a 4×4 tent? In most cases, a 4-inch carbon filter will be more than enough for a 4×4 tent. Since a 4×4 tent has a relatively small internal volume a 4-inch carbon filter should easily remove all the odors from the air before they are exhausted from the tent.

If you plan on running an HPS (High-Pressure Sodium) light you might want to run a larger 6-inch carbon filter with a high CFM fan. In that case, you’ll need to vent a lot of excess heat, and you’ll want to get a larger carbon filter and fan to cool down the tent.

It’s also important to size your fan accordingly so the carbon filter operates at peak performance. For that reason it’s a good idea to get a carbon filter fan combo, so you can be sure that the carbon filter and fan will work together to keep odors from leaking out of the grow tent.

 

 

Do Carbon Filters Remove Odor

Do Carbon Filters Remove Odor

A properly installed carbon filter can reduce plant odors by up to 99%. Although, they might have some trouble when your plants are in their later stages of flowering, and they won’t do much if you’re always opening up the tent.

Carbon filters work by permanently trapping molecules inside their complex pore structure. They are especially good at capturing the main source of plant odors (terpenes) since activated carbon forms strong bonds with organic compounds.

In order to make sure that your carbon filter removes as much odor as possible, you’ll need to have a strong inline fan in your 4×4 tent to provide adequate ventilation. The grow tent will also need to be kept in a constant state of negative air pressure, so all of the air goes through the filter and out the exhaust vent.

You also might want to look into an ozone generator, if you really want to neutralize any lingering odor that the carbon filter might have missed.

How Long Do Carbon Filters Last

A carbon filter can last for a year or more as long as you properly maintain it. The number one thing you can do to extend the life of a carbon filter is to protect it from dust. Dust will slowly start to clog the small pores in the carbon filter, which can reduce its effectiveness. The dust will also restrict airflow which can put excess strain on your fan.

That’s why it’s always a good idea to run a pre-filter on your carbon filter to trap the dust before it can clog the activated carbon. If you run a pre-filter you’ll have to replace it every 3 to 6 months, or when the dust builds up enough to reduce the air flow in your tent.

Of course, over time the carbon itself will become less effective at removing odors, and it will need to be replaced. This can take up to a year or more depending on the size of your carbon filter and how hard it had to work over its lifespan.

Once you start to notice more odors escaping the tent then that’s a good sign that the carbon filter needs to be changed.

 

 

How to Clean Activated Carbon Air Filter

A carbon filter really can’t be cleaned since the activated carbon forms strong chemical bonds. That means once it’s spent the only thing you can really do is get a new carbon filter.

If you just want to clean some dust and debris off the filter you can lightly brush it off, or you can gently vacuum it if it’s stuck in the vents. The best way to avoid dust build up in the first place is to use a pre-filter to keep the carbon filter running at peak performance.
