Routine sensor cleaning and filter replacements guarantee an enduring partnership.

On average, we find HEPA filters need to be replaced every 6-12 months and carbon filters every 12 months depending on usage.
You will also need to wash the pre-filter as needed, but make sure to let it dry completely before putting it back into the air purifier.

In 1 hour it can circulate through a 1,001 sq. ft. area 4 times and a 2,001 sq. ft. area 2 times. In addition, the device has wheels, so it’s easy to move around if needed.
