What is the purpose of the PreSorb® prefilter?
The PreSorb® prefilter adsorbs odors and is the first line of filtration catching the larger particles. It uses activated carbon to adsorb odors and other organic compounds. Activated carbon is the best adsorbent available to aid in the reduction of common household odors and organic compounds. Trapping the larger particles will extend the life of the HEPA filter.
