A lot of air purifiers are advertised as HEPA but really contain a filter stack consisting of a pre-filter, a HEPA filter and an activated carbon filter. Those would presumably help against VOCs, assuming you change the filter frequently enough
- s0rce 1y agoFrequent replacement is critical, my understanding is the activated carbon filters typically provided have very limited capacity. More so when compared to the lifetime of the hepa.
- bonesss 1y agoCompare those air ‘purifiers’ with the activated charcoal setups they use on cannabis grow operations, and you’ll get a sense of what volume of charcoal and air circulation is necessary to combat those small particulates. Purifiers help in theory but are nowhere near effective or active enough to combat off gassing or VOC dispersals in practice.
