Levoit vs Alen Air Purifier Comparison
Filtration Grade
Both units use HEPA technology, but the specific grade differs. The Levoit Core 300-P utilizes a HEPA-grade filter that captures 99.97% of particles as small as 0.1 to 0.3 microns. The Alen BreatheSmart 35i includes an H13 HEPA filter, which is a stricter classification capable of removing 99.9% of allergens, germs, and bacteria down to 0.1 micron. While both effectively target fine particulates, the Alen’s H13 rating represents a higher standard of filtration efficiency for the smallest airborne pollutants.
Room Coverage
Coverage area is a key factor for placement. The Alen BreatheSmart 35i is engineered for larger spaces, covering up to 1,400 square feet. It circulates air efficiently in large bedrooms, living rooms, or offices. In contrast, the Levoit Core 300-P is rated for a 222 square foot room, refreshing the air 4.8 times per hour, or up to 1,073 square feet once per hour. If you need to clean a single medium room quickly, the Levoit is sufficient. For whole-home or large open area coverage, the Alen provides significantly broader reach.
Noise Performance
Quiet operation is vital for bedroom use. The Levoit Core 300-P features QuietKEAP Technology, allowing it to operate at a near-silent 24 dB in Sleep Mode. This makes it nearly undetectable during the night. The Alen BreatheSmart 35i is also designed for quiet operation, utilizing pink noise technology to optimize lower octave frequencies for restful sleep. While both prioritize silence, the Levoit provides a specific decibel measurement for its lowest setting, offering a quantifiable advantage for users sensitive to even minimal sound output.
Smart Features
Automation capabilities vary between the two brands. The Alen BreatheSmart 35i includes a SmartSensor that adjusts fan speed based on real-time air quality. It provides color-coded feedback, with blue indicating excellent air and purple signaling high particle presence. The Levoit Core 300-P does not list an air quality sensor or automatic mode in its specifications. Instead, it offers manual controls including a timer for 2, 4, 6, or 8 hours and a filter check indicator. If you prefer automatic adjustment, the Alen is the better choice.
Certifications
Verification of performance standards helps ensure reliability. The Levoit Core 300-P is AHAM Verified, meaning it has been independently tested for air cleaning performance and energy efficiency according to strict ANSI standards. It also holds FCC, ETL, and CARB certifications. The Alen BreatheSmart 35i highlights its H13 HEPA filtration and energy efficiency but does not list AHAM verification in the provided data. For buyers who prioritize third-party performance certification for CADR ratings, the Levoit offers documented proof of its cleaning power.
Which Levoit or Alen model fits you
You need verified airflow for small rooms
The Levoit Core 300-P carries the AHAM Verified seal, confirming its Clean Air Delivery Rate of 143 CFM. This certification ensures the performance claims are independently tested. It refreshes air in a 222 square foot room nearly five times per hour. This verified data provides confidence in its cleaning speed for smaller spaces.
You want coverage for large open areas
The Alen BreatheSmart 35i lists a room coverage of 1,400 square feet. This capacity exceeds the Levoit model, making it suitable for larger living areas or open floor plans. It is designed to circulate air efficiently across these larger dimensions while maintaining quiet operation for continuous use in expansive home environments.
You prefer automated air quality monitoring
The Alen unit features a built-in SmartSensor that adjusts fan speed based on real-time air quality. It provides color-coded feedback, with blue indicating excellent air and purple signaling high particle levels. This automated adjustment removes the need for manual mode changes, allowing the device to respond dynamically to your indoor environment.
You prioritize ultra-quiet nighttime operation
The Levoit Core 300-P operates at a noise level of just 24 decibels in Sleep Mode. This near-silent performance ensures undisturbed rest. It also allows you to turn off the display lights completely. This combination of low decibel output and customizable lighting makes it an ideal choice for light sleepers seeking a quiet bedroom companion.
