This pack includes multiple black pre-filters designed specifically for the HPA300 series air purifiers. The pre-filter, marked as 'A' filter type, acts as the first line of defence by capturing larger airborne particles like dust, pet hair, and lint. By regularly replacing these pre-filters, you help maintain optimal airflow and extend the life of your main HEPA filter. These sturdy, well-constructed filters are precisely cut to fit your unit perfectly. For best results, it's recommended to check and replace your pre-filter every 3 months, depending on usage and air quality conditions. Each filter in this multi-pack provides consistent performance throughout its service life, helping to maintain your indoor air quality.

These pre-filter are much thinner and less fiber than the original. I won't get them again.
