Best carbon filters

Alright I answered my own question and in case anyone else is wondering. I figured the housing would be easy but I didn’t know what kind of charcoal you’d refill the thing with. Looking like ‘4x8 activated carbon’ gets me the right stuff. Gonna order a big ass bag and try to refill this time so wish me luck haha.
Youll want to make a vibrating table to help pack it, so like a table saw motor with an off balance pulley or a piece of machinery that vibrates when running.Anything will work even a palm sander held against it will help it pack down.

Just bounce the new filled filter on th floor a few dozen times, you’re fine. A lot of filter outfits make the whole process sound over-complicated and mysterious. Just so they can sell more filters. It is actually simple and 100% effective.

I grow in soil and I’m a bread maker so I’m really good at making messes lmao! I picture myself looking like a chimney sweep when it’s done but I’ll have the satisfaction that I at least tried.

Thanks for the tips!

^ yep Amazon had a few options. I forgot to check eBay. I was cringing designing my new space and thinking more/bigger filters would be needed to maintain it how I like. I just pulled the trigger on a 55 lb bag which should refill all my filters a few times. Gonna end up saving me a ton.
Plus I read you can bake the used charcoal to refresh it. Anyone done this?

I was looking into baking my charcoal but I soon discovered the temperature required to bake out the smells are not attainable with a standard kitchen stove.

The mesh inside the filter? I’m not sure and hoping to reuse whatever is in there already. Gonna open the housing dump out the old and pack in the new. Improvise with what’s there. The few posts around the net I found on it didn’t seem to run into much troubles. Hoping that won’t be an issue. I’ve done a lot with cheap nylon stocking though and would start there.


I told my wife hey you know how they say bad boys get coal for Christmas? Haha

They call it ‘4x8 mesh sized activated carbon’ there we go heh. Sorry I should have realized that’s what you were askin myself. I chose the EnviroSupply version. The companies site was $10 more total after shipping than their Amazon merch page here:

Also read this walk through and could see some things that could make this a bit of a pain but not too horrible at all.

Once I have the stuff and can do this I’ll post up the mess I make.

When refilling, I cover the center perforated tune with inverted Solo cup on 4”. Bounce the filter starting with first few inches to compact charcoal.
