Honeywell 3 Pack of True HEPA Filters F (Replaces Filter 24000)

The Replacement HEPA Air Purifier F Filter is certified to help capture up to 99.97% of microscopic airborne allergens and particles as small as 0.3 microns. This includes dust, pollen, pet dander, dust mite debris and smoke.

Designed to fit Honeywell air purifier models 50250 and 13520 (or to replace HEPA filter no. 24000).

1. Three HEPA filters and one foam gasket will be needed for the 50250 and 13520 Honeywell air purifier.
2. Carefully stack all three HEPA filters on top of each other, so they are evenly aligned.
3. Once all three HEPA filters are stacked and aligned, place 1 foam gasket on the top of the stack.
4. The foam gasket is needed to form a tight seal in the air purifier.
5. Optionally, if you are using a Pre-Filter, carefully wrap the black carbon Pre-Filter around the stack of HEPA filters.
6. Place the wrapped filters, with the gasket on top, into the internal chamber of the air purifier.
7. Make sure the foam gasket is facing up and at the top of the stack while in the unit.
8. After filter replacement is finished you may reset the filter check light.

These HEPA filters should remain efective for 1-5 years, depending on the environment in which the air purifer is operating. Replace your HEPA filters every 3-5 years for light situational usage, every 2-3 years for normal seasonal usage and every year for heavy daily use.
