WHY CHOOSE AHAM VERIFIDE AIR PURIFIERS: AHAM (Association of Home Appliance Manufacturers) is an ANSI-accredited organization that sets strict standards for appliance performance. Air purifiers with the AHAM VERIFIDE seal have been independently tested for air cleaning performance and energy efficiency. When you choose an AHAM certified air purifier, you're choosing a product trusted for reliable and effective indoor air quality improvement
WHISPER-QUIET AIR CLEANER: Select Sleep Mode at night and forget all about your air purifier while you sleep. QuietKEAP Technology reduces noise levels to a near-silent 24dB in Sleep Mode
UNDISTURBED OPERATION: The display lights can be turned off to enjoy a perfect night without being distracted by the light. The display also features a timer for 2, 4, 6, or 8 hours as well as a check filter indicator
SLEEK DESIGN: The Core 300-P Air Purifier effectively purifies your home while blending in with your decor. Its modern white finish ensures that it fits in any room in your home
MULTIPLE FILTER CHOICES: Choose from a variety of replacement filters to best meet your needs. The Toxin Absorber Filter specializes in smog, toxins, and VOCs, while the Smoke Remover filter addresses smoke from wildfires, smoke, and other particulates. The Pet Allergy Filter captures pet dander and adsorbs unpleasant odors
HIGH-PERFORMANCE AIR PURIFICATION: A powerful 56W high-torque motor and 143 CFM CADR delivers fast, effective cleaning. The Levoit Original Filter is HEPA-grade while operating in Sleep Mode (Based on IEST RP C001.7). Ideal for home, bedroom, or office
GENUINE REPLACEMENT FILTERS: For the best performance and longest lifespan, use official Levoit filters designed specifically for Levoit air purifiers. Levoit replacement filters ensure the best fit and high-efficiency filtration, while off-brand filters may be unreliable and may damage your Levoit air purifier
FIND COMFORT: Our filter has strong filtration performance of fine particles. 99.97% filtration efficiency for 0.1 to 0.3μm airborne particulates, including pollen, dust, and animal dander allergens. Tested by an independent lab
CERTIFIED SAFE FOR HOME USE: The Core 300-P is AHAM verified, FCC Certified, ETL Listed, and CARB Compliant for California indoor air quality standards. Notes: The voltage of the air purifier is 120V and is suitable for use only in the United States
AHAM VERIFIDE, PROVEN PERFORMANCE: AHAM VERIFIDE with a CADR (Clean Air Delivery Rate) rating of 143 CFM for smoke, 153 CFM for dust, and 167 CFM for pollen—refreshing air in a 222 ft² room 4.8 times per hour and a 1,073 ft² room once per hour
