Just started looking at these carbon air filters such as Can Filter, HF's ActiveAir, and a ton of knockoffs on eBay which seem to have similar specs. Some are coconut carbon, some mined carbon(RC-48? CTC60? among others), all between 1.5" to 2.5" depth of carbon. I'll be recirculating the air in a sealed room with it. Just a bit daunted by all the choices. Anybody happy with eBay ones? Or is the CanFilter superior? Or another brand?
