Rosewill Air Purifier Replacement Filter for Rosewill True HEPA Air Purifier - (RHAP-20003)

True HEPA Replacement Filter

The RHAP-20003 True HEPA Replacement Filter fits both the Rosewill RHAP-20001 and RHAP-20002 air purifiers and features a 4-Stage purification system that filters out pathogens like mold, smoke, fur, dust, and more. A pre-filter helps remove larger materials such as hair, fur, and dust. This helps extend the HEPA filter's lifetime which means you buy less replacement filters. The antibacterial coating contains organic metal salts and antibacterial agents to prevent mold, bacteria, and dust mites from developing. The true HEPA filter can filter 99.7% of air particles as small as 0.3 microns, including pollen. Finally, the activated carbon removes orders and absorbs harmful substances like gas and smoke. Best of all, the filter is built to last; each filter has a lifespan of up to 2200 hours, meaning you won't need to constantly purchase or replace filters.

4-Stage Purification System

The 4-stage purification process includes 4 layers which each accomplish specific tasks to remove harmful pathogens. The four layers and stages of the purification process are:

1. Pre-Filter — Filters out larger materials such as hair, fur, and dust. This helps extend the HEPA filter's lifetime which means you buy less replacement filters.

2. Antibacterial Coating — Contains organic metal salts and antibacterial agents to prevent mold, bacteria, and dust mites from developing.

3. True HEPA Filter — A High Efficiency Particulate Air, also known as HEPA, can filter 99.7% of air particles as small as 0.3 microns, including pollen.

4. Activated Carbon — Removes orders and absorbs harmful substances like gas and smoke.

Combined, these layers work to efficiently and effectively filter our harmful air particles, smokes, and other pathogens to provide cleaner, healthier, air for you and those around you.
