Genuine HEPA replacement for KC-850U

The Sharp FZ-C100HFU is a factory-original HEPA filter designed specifically for the KC-850U air purifier. It restores the unit’s rated particle-capture performance when the original filter reaches the end of its service life. Home owners and facility managers who operate the KC-850U can maintain indoor-air quality without adapting third-party media.

Steady airflow with no added noise or power draw

Because the filter matches the KC-850U’s original specifications, the purifier’s fan curve, sound level and electricity consumption remain unchanged after installation. The dense HEPA media traps fine dust and allergens while presenting the same resistance the appliance was engineered for. No recalibration or higher fan speeds are required to compensate for pressure drop.

Drop-in fit eliminates installation guesswork

The filter cartridge slides into the KC-850U housing using the existing rails and latches, so no tools, adapters or firmware updates are needed. A tight seal prevents bypass leakage that would let unfiltered air recirculate. Replacing the element at the manufacturer’s suggested interval keeps the purifier operating at its tested clean-air delivery rate.

Questions about this item

How do I install the FZ-C100HFU HEPA filter into the KC-850U air purifier?

Open the front panel of the KC-850U, remove the old filter, insert the new FZ-C100HFU with the airflow arrow pointing inward, then close the panel securely.

When will the FZ-C100HFU HEPA filter need replacement in the KC-850U?

Replace the filter when the KC-850U indicator light signals end of life or after the manufacturer's recommended operating hours for the model.

What is the first performance limit of the FZ-C100HFU under continuous use in the KC-850U?

The filter reaches its particle-holding capacity first, causing airflow resistance to rise and the purifier's indicator to signal replacement.
