Product Specifications

Package Includes

• 1 × Nispira True HEPA filter
• 4 × Nispira activated carbon pre-filters

Installation

No tools or special expertise required.

1. Turn off and unplug your air purifier before servicing.
2. Remove the existing HEPA filter and/or carbon pre-filter from the unit.
3. Confirm the filter model number or dimensions match your unit.
4. Insert the Nispira HEPA filter and carbon pre-filter in the correct orientation.
5. Close the compartment and restart the purifier.

Always follow your air purifier's manual for filter access and orientation.

Filtration and Maintenance

• True HEPA filter: Captures up to 99.97% of airborne particles as small as 0.3 microns. Suggested replacement: approximately every 6 months.
• Activated carbon pre-filter: Removes odors, smoke, and VOCs, and traps larger particles like hair and dust before they reach the HEPA layer. Because carbon media saturates faster, suggested replacement: approximately every 3 months.

Actual replacement frequency depends on usage and indoor air quality.
