Vornado Compatible AQS15 Presorb Pre-Filters - 2-Pack (compare to Vornado #MD1-0010) are pre-cut to replace the Presorb® pre-filter that comes in the Vornado AQS15 air purifier. Activated charcoal pre-filter reduces odors and captures larger airborne particles before they reach the HEPA filter. Change pre-filter every 3 months, depending on use. Package contains two (2) Charcoal Pre-Filters.
