It captures up to 99.99% of airborne pollutants such as dust, pollen, pet dander, smoke, gases and odors—so the air you breathe stays clean.
The Replacement Filter uses an advanced three-layer filtration system for comprehensive air purification. The pre-filter captures larger particles, such as dust and pet hair, helping to extend the life of the additional filters. The HEPA filter removes up to 99.99% of microscopic particles as small as 0.1 microns, significantly improving indoor air quality. Finally, the activated carbon layer neutralizes odors, smoke, and VOCs.
In accordance with EPA.gov guidelines, we recommend replacing your air filter every 90 days to maintain the highest air quality. More frequent replacements may be necessary during increased pollution, such as wildfire season or significant renovations. Regular filter changes ensure your purifier provides a healthier environment, which can also enhance cognitive function and help reduce respiratory issues.

We recommend replacing your air purifier filter every 3 months or 90 days. Due to build-up of captured air pollutants, waiting longer than 90 days could decrease the effectiveness of your air purifier. During periods of poor air quality due to increased allergens, wildfire smoke, renovation projects, airborne illnesses, etc. we recommend replacing the filter sooner.
We’re not about pseudoscience or half-truths. So we challenged some of the top scientists to help us develop the ultimate air purification filter. The result is everything an air purifier should be, without the fluff and the nonsense.
