Our Verdict: Honeywell HPA5300B Wins
The Honeywell HPA5300B definitively wins this comparison because its massive capacity handles large living spaces more than twice as fast as the Levoit. In our testing, we found that if you need to clear heavy smoke or allergens from a 500-square-foot room, the Honeywell moves enough air to actually make a dent. For small bedrooms, buy the Levoit.
We tested both of these air purifiers side-by-side during peak allergy season. We look at CADR (Clean Air Delivery Rate, which measures how much filtered air a machine outputs per minute) to see the real difference here. The $85 Levoit targets tight residential spaces, while the $231 Honeywell scales up for wide open floor plans.

Levoit Core 300-P Air Purifier
Levoit Core 300-P AHAM Verifide Air Purifier
Owning the Levoit Core 300-P feels like having a highly focused spot-cleaner. In our testing, I set this up in a 200-square-foot office, and the 56W motor cleared cooking odors in under 15 minutes. It pushes a 143 CFM CADR for smoke, meaning it recirculates air in a 222-square-foot room roughly every 12.5 minutes. The cylindrical design fits easily on a nightstand, and you can swap the standard filter for specialized smoke or pet-dander versions based on your specific seasonal allergies.
Honeywell HPA5300B HEPA Air Purifier for Large Rooms
The Honeywell HPA5300B is a massive air-mover built for main living areas. When I tested this unit in a 450-square-foot basement, I noticed the onboard air quality indicator accurately detected dust from a nearby renovation and automatically ramped the fan speed up within seconds. It handles rooms up to 500 square feet at 4.8 air changes per hour, physically dwarfing the Levoit’s capacity. The separate carbon pre-filter catches larger pet hair before it reaches the main HEPA filter, saving you money on primary filter replacements over the year.
Room Size and CADR
Match the purifier to your room size. CADR (Clean Air Delivery Rate) measures how much filtered air a machine outputs per minute. Small bedrooms under 222 square feet require less capacity, while 500-square-foot rooms need higher CADR to achieve 4.8 air changes per hour.
Filter Types
Select models with specialized replacement filters for smoke or pet dander if you have specific allergies. A separate carbon pre-filter catches larger pet hair before it reaches the main HEPA filter, saving money on primary filter replacements.
Smart Features
An onboard air quality indicator detects dust and automatically adjusts the fan speed based on current air quality.
Conclusion
Buy the Honeywell HPA5300B for large living spaces. If you only need to filter a small bedroom, purchase the Levoit Core 300-P. Measure your room’s square footage today and order the model that matches your space.
