While the PuroAir air purifier's HEPA filter works to reduce airborne particles, it also accumulates them. This buildup can eventually block airflow and diminish the filter's ability to screen pollutants.
To ensure that your PuroAir 240 air purifier continues to operate at its best and effectively filters airborne contaminants, it's crucial to replace the HEPA filter regularly. By replacing the filter, you're restoring the air purifier's ability to clean the air of harmful particles, maintaining a healthy air environment in your home or office.
The PuroAir 240 air purifier features a filter replacement indicator light conveniently located on the control panel. This light will illuminate to signal when it's time to replace the filter. Additionally, you can visually inspect the filter itself. If you notice excessive dust buildup or discoloration, it's a good indication that the filter needs to be replaced.
No, HEPA filters should not be washed. Cleaning them can cause damage and reduce their effectiveness to screen small particles that may not be visible to the human eye. To maintain optimal air purifier performance, replace the HEPA filter according to the recommended schedule or every 90 days or 3 months.
