We recommend replacing your 100i air purifier filter every 3 months or 90 days to maintain optimal performance. Failing to do so may result in decreased effectiveness due to the accumulation of collected pollutants. Your air purifier is designed with an internal countdown timer that tracks your usage and notifies you when it is time to replace the filter. The Filter LED on the purifier will illuminate once the countdown has been reached. Once you install the new filter, simply hold down the filter button for 3 seconds to reset the timer countdown.

However, consider replacing the filter sooner during periods of poor air quality caused by increased allergens⁴, wildfire smoke¹, home renovations, or other similar factors. If there is less pollution and your air purifier isn't used as often, you might only need to replace the filter every 6 months.

While the PuroAir 100i air purifier's HEPA filter works to reduce airborne particles, it also accumulates them. This buildup can eventually block airflow efficiency and diminish the filter's ability to screen pollutants.
