The Eleva 300X is recommended for rooms up to 250 square feet, making it an ideal HEPA air purifier for bedrooms, home offices, and other small-to-medium spaces. It delivers approximately 4.8 air changes per hour (ACH) in a 250 sq ft room, meaning it can clean the air every 12.5 minutes. Despite its powerful airflow, it operates quietly for everyday use.

The Eleva 300X has an AHAM Verifide® Clean Air Delivery Rate (CADR) of 161 CFM (274 m³/h) for smoke, dust, and pollen. CADR measures how quickly an air purifier delivers clean, filtered air – a higher CADR means faster air cleaning and better performance in appropriately sized rooms. The Eleva 300X delivers enough clean air to provide approximately 4.8 air changes per hour (ACH) in a 250 sq ft room.

The Eleva 300X features system-level HEPA filtration that captures 99.97% of airborne particles as small as 0.3 microns, including dust, pollen, pet dander, microplastics, and smoke particles. Its interchangeable carbon filters also help reduce cooking odors, smoke, VOCs (volatile organic compounds), and other household gases.

Yes. The Eleva 300X is designed to reduce common allergy triggers, including pollen and dust.

The Eleva 300X uses a built-in AirSight Plus 2.0 air quality sensor that continuously monitors PM1.0, PM2.5, and PM10 – three distinct particle sizes that correspond to different types of indoor pollutants. In Auto Mode, the purifier automatically adjusts fan speed based on your real-time air quality, and the VeSync app shows real-time readings and historical air quality reports.

The DuoShield™ modular filter design lets you replace the particle filter and carbon filter separately, which lowers long-term maintenance costs. The particle filter lasts up to 2 years, while carbon filter life ranges from 6 to 12 months depending on the filter type you choose. The VeSync app tracks remaining filter life and notifies you when a replacement is due.
