    Removes allergens

    AFTER we adopted our long haired cat, my husband and I both realized that we were allergic to her. Keeping the Honeywell air purifier in our bedroom has enabled us to sleep well. When the pre-filters are changed regularly, the air purifier can continue working indefinitely.
