    Product Description

    The Honeywell HPA3100 PowerPlus HEPA Air Purifier helps provide cleaner, fresher air in medium to large rooms. HEPA Filtration helps capture up to 99.97% of the following microscopic airborne allergens and particles: dust, pollen, pet dander, dust mite debris and smoke.* This Honeywell air purifier is independently tested and AHAM Verifide to circulate and filter room air up to 4.8x per hour in a 200 sq. ft. room.** This quiet air purifier has 4 intuitive cleaning levels, auto-off timer option at 2, 4, or 8 hours, a dimmer option for control panel lights, filter check/reset indicator and initial filters included. Customize your filtration experience with optional Honeywell Enhanced Odor & VOC T Filters that help tackle specific household odors from pets (HRFTP1), kitchens (HRFTK1), and smoke (HRFTS1) or home renovation VOCs (HRFTC1) (sold separately). This Honeywell PowerPlus series HEPA Air Purifier delivers powerful, efficient filtration with a compact design. Earned the ENERGY STAR label by meeting strict energy efficient guidelines set by the U.S. EPA. Always purchase Genuine Honeywell replacement air purifier filters. Compatible replacements are not guaranteed to offer the same performance or efficiency – they may be cheaper but need to be replaced more often, which ends up costing more in the long run. Disclaimers: * From the air that passes through the filter, 0.3 microns and larger. ** When operated with the odor reducing filter. It is recommended to always use the pre-filter when operating this air purifier. Pre-filter should be replaced every 3 months to effectively reduce common household odors and VOCs in a room. *** Based on 3rd party independent CADR testing for the smoke CADR value when operated at the highest level. Air circulation depends on many factors, such as room size and configuration. There is no guarantee that all of the air in a room will pass through the filter. The ENERGY STAR name and mark are registered trademarks owned by the U.S. EPA.
