[This review was collected as part of a promotion.] :LOVE my new Puraclenz Core! So grateful I learned about it from functional mold specialists who know what type of purifiers truly work for those exposed to a moldy home. Hard to believe that such a machine not only runs so quietly (almost as if it isn't on at all), but even 1 purifier is enough to make such a strong impact on the air quality throughout my 1200 sq. ft. home even though it's been placed in the master bedroom where the worst mold is located. My symptoms relating to my mycotoxin illness (primarily headaches, brain fog, joint pains, & sleep difficulties) from mold exposure have begun to diminish in a short time. While it is still necessary for my husband and I to find another home to move into, our new Puraclenz Core is helping us breathe easier and endure better than before we had brought it into our home. This needs to be in home/work place where the air has been contaminated by mold, VOC's, & other hazardous environmental elements!
