Q: How many filters does KC-850U have? How long does the filter need to change?
A: Thank you for your recent inquiry regarding the Sharp KC-850U Air Purifier.The air purifier draws in room air from the air intake, passes the air through a Pre- Filter, a Washable Deodorizing filter and a True HEPA filter inside of the unit, then discharges the air through the air outlet. Some odors absorbed by the filters may break down over time, resulting in additional odor. Depending on the usage environment, especially when the product is used in extreme environments (significantly more severe than normal household use), this odor may become strong in a shorter period than expected. If the odor persists, the filters should be replaced. Guide for filter replacement timing True HEPA filter - Up to 5 years after opening Filter life can be greatly reduced depending on the room environment. Cigarette smoke, pet dander, and other airborne particles can reduce filter life. Check filters regularly and replace as necessary. Washable Deodorizing filter - Up to 5 years after opening The filter can be repeatedly used after washing, or it can be replaced. Humidifying filter - Up to 2 years after opening Filter life can be greatly reduced depending on the room environment.
