AirPura Prefilter for 6-Series and 7-Series

This pre-filter is specifically designed for the AirPura 600, 614, 700, and 714 series units.

Both materials provide the same MERV 8 filtration performance. The organic cotton option is simply a natural, non-synthetic alternative for those who prefer plant-based materials in their home environment.

To maintain optimal airflow and filtration, you should vacuum or clean the pre-filter every three to six months. We recommend replacing the filter entirely every 6 to 12 months, depending on your home's air quality and dust levels.

Yes, the MERV 8 rating is effective at capturing larger airborne particles, including dust, pet dander, and larger smoke particulates, which helps extend the life of your unit's primary HEPA filter.

The overcloth is optional, but it acts as an additional layer of protection that can help extend the lifespan of your pre-filter by catching larger debris before it reaches the filter media.

While the filter is designed to be cleaned, it is generally recommended to use a vacuum attachment to remove dust and debris. If you choose to wash it, ensure it is completely air-dried before reinstalling it to prevent moisture buildup inside your unit.
