The PuroAir 240 is built with medical-grade H14 HEPA media, which is designed to capture 99.99% of fine particles as small as 0.1 microns. This makes it a high-performance option for households that want a higher level of filtration than the standard H13 models. The internal fan uses a centrifugal design and a brushless DC motor, which helps the unit run very quietly, reaching as low as 22dB in its sleep mode.
The chassis is made from high-impact plastic, providing a rigid and quiet frame. A built-in laser sensor monitors the air quality in real-time, providing feedback that the unit uses to adjust its speed when in "Auto Mode." While it is capable of managing larger spaces, it is most efficient in rooms between 200 and 400 square feet where it can cycle the air several times an hour to keep things fresh.
- H14 Grade HEPA media is technically superior for capturing ultra-fine smoke and viral particles.
- The PM2.5 laser sensor provides high-accuracy readings for the auto-adjustment feature.
- Acoustically optimized to avoid the high-pitched "whine" often found in smaller motors.
For the most accurate readings, it is best to place the unit about 15 inches away from walls to ensure air can circulate properly around the sensor. This model is a great choice for those who want high-end filtration performance without the need to manage a smartphone app or Wi-Fi connection.
If you are looking for a unit that is more compact for use specifically on a desk or small nightstand, the Levoit Core Mini-P is a practical alternative. You can find more specialized air cleaning tools in our HEPA air purifiers category.
