Airpura Replacement 100% Cotton Pre-Filter

This pre-filter is designed to capture large airborne particles like dust, pet hair, and pollen before they reach your main HEPA or carbon filters. By trapping this debris early, it prevents your primary filters from clogging prematurely, which helps extend their overall lifespan.

Maintenance is straightforward. You can simply vacuum the exterior of the filter to remove accumulated dust and debris. This process restores airflow and keeps the filter functioning efficiently between replacements.

While the filter is reusable and can be cleaned by vacuuming, it is not permanent. You should expect to replace the filter every 6 to 12 months, depending on your home's air quality and the amount of dust or pet dander present.

No. These filters are made from 100% unbleached, pesticide-free cotton. This makes them a great choice if you are looking to avoid synthetic materials or chemical treatments in your air purification system.

These pre-filters are specifically engineered for compatibility with Airpura air purifiers. They are sized at 12 inches by 45 inches to fit the specific housing of Airpura units, so they may not fit other brands properly.
