Carbon air scrubber

Anyone have any suggestions for/ or have used successfully a specific model of carbon air scrubber for 4-5 plants? They will be in a closet growing w/ three 46 watt clf's, but in a shed to dry. Thx

Check this out for a step by step on building a carbon scruber (https://www.rollitup.org/do-yourself/2758-carbon-scrubber.html). Probably will support 4-5 plants.
