Triple-Layer HEPA & Activated Carbon Filters

The PuroAir HEPA Replacement Air Filter is a high-efficiency, 3-layer filter designed to fit PuroAir HEPA air purifiers. It's composed of a pre-filter screen layer to filter large particles, a HEPA filter layer to filter up to 99.9% of microscopic allergens* and pollutants, and an activated carbon filter layer to filter odors, smoke, and harmful VOCs. This best-in-class filtration system effectively filters airborne particles like dust, pollen, pet dander, and other allergens*, ensuring the highest quality air and a healthier environment in your home or office at all times.

We recommend replacing your air purifier filter every 3 months or 90 days. If not replaced within this timeframe, the effectiveness of your air purifier may decrease due to the build-up of captured air pollutants. However, during periods of poor air quality caused by increased allergens*, wildfire smoke, home renovations, and other factors, it is recommended to replace the filter sooner.

Failing to replace the filter when needed will result in decreased air purifier effectiveness, allowing pollutants and allergens* to circulate in your home. This decreased efficiency will also force the unit to work harder, potentially causing increased energy consumption, strain on the motor, and premature wear and tear.

Replacing the filter is a simple process. First, power off the air purifier and unplug it. Open the filter compartment and remove the old filter. Insert the new PuroAir HEPA replacement filter in the same position, ensuring it fits securely. Close the compartment, power the unit back on, and reset the filter indicator. Hold down the button until the indicator light turns off, signaling that the system has been reset.
