AirPura R400 Air Purifier

The R400 is designed to purify spaces up to 1,000 square feet, assuming standard 8-foot ceilings. Its 360-degree air distribution system ensures that air is circulated and cleaned efficiently throughout the entire room.

No, the AirPura R400 does not produce ozone. It relies on mechanical filtration—specifically a HEPA filter and an activated carbon filter—to clean the air rather than ionization or other ozone-generating technologies.

Maintenance is straightforward: the pre-filter should be vacuumed regularly and replaced every 12 months. The activated carbon filter typically lasts for 2 years, while the HEPA filter is designed to last up to 3 years, depending on your environment.

Yes, it is highly effective for that purpose. The unit contains an 8-pound activated carbon filter specifically engineered to adsorb a wide range of airborne chemicals, gases, and everyday household odors.

While noise levels depend on the fan speed setting, the R400 is designed for consistent, high-performance airflow. At medium speeds, it is generally quiet enough for home or office environments, though you will notice a gentle hum of air movement.

The H13 HEPA filter is rated to capture 99.97% of airborne particles as small as 0.3 microns. This includes common allergens like pollen, dust, and mold spores, making it a strong choice for those with sensitivities.
