Why does my Sharp KC-G40L Air Cleaner smell?
If the air discharged from your Sharp Air Cleaner has an odor, check if the filters are extremely dirty and clean or replace them. Also, ensure you are using fresh tap water. Using other water sources can lead to the growth of mold, fungi, or bacteria.
How to eliminate persistent odor and smoke from my Sharp KC-G40L?
If odor and smoke persist when using your Sharp Air Cleaner, check the filters. If they appear extremely dirty, clean or replace them.
What to do if the Sharp Air Cleaner displays an error?
Make sure that the Humidifying Filter and Humidifying Tray are properly installed, and then turn the power to ON again. Alternatively, unplug the unit, wait one minute, and then plug the unit in again.
Why doesn't the HAZE/PM2.5 Light match local data on my Sharp KC-G40L Air Cleaner?
Outdoor and indoor conditions, as well as the home environment (the volume of traffic nearby, number of stories in home, etc.) may cause a reading different than local PM2.5 data.
Why is there a discrepancy between the unit’s Humidity Monitor and another hygrometer in the room with my Sharp KC-G40L Air Cleaner?
There is a difference in the humidity level within the same room. The sensor have different measurement parameters. If the monitor indicates wattage or temperature, switch the display by pressing the DISPLAY SELECT button.
What to do if the Cleanliness Monitor light is red even when the air is clean on my Sharp KC-G40L?
If the Cleanliness Monitor light is red on your Sharp Air Cleaner even when the air is clean, the dust sensor openings may be dirty or clogged, interfering with sensor operation. Gently clean the sensor filter or the back panel.
Why doesn't the Humidify Light turn on when the tank is empty on my Sharp Air Cleaner?
If the Humidify Light on your Sharp Air Cleaner's display doesn't light up when the tank is empty, check the styrofoam float for impurities, clean the Humidifying Tray, and ensure the unit is on a level surface.

This document describes the Sharp KC-G60E, KC-G50E, KC-G40E, KC-G60L, KC-G50L, KC-G40L, KC-G60M, and KC-G40M series of air purifiers with humidifying function. These devices are designed to improve indoor air quality through a combination of filtration, Plasmacluster ion technology, and humidification.
The Sharp air purifier operates by drawing in room air through an intake, circulating it through a multi-stage filtration system, and then discharging purified air through an outlet. The filtration system includes a Pre-Filter, a Deodorizing Filter, and a HEPA Filter. The Pre-Filter captures larger dust particles, while the Deodorizing Filter absorbs harmful gases and common household odors. The HEPA Filter is highly effective, trapping 99.97% of particles as small as 0.3 microns, including tiny dust, pollen, and mold spores.
In addition to filtration, the device incorporates Plasmacluster ion technology. This feature emits a balanced combination of positive and negative ions into the air, which is described as a natural process that freshens the air. The Plasmacluster Ion Spot Mode specifically targets adhering odors, germs, and other substances on fabrics, sofas, and curtains by emitting high-density Plasmacluster ions in a forward direction for 8 hours, after which the unit returns to its previous operating mode. The Plasmacluster ion function can be manually turned ON or OFF, though it cannot be turned OFF in HAZE mode.
The humidifying function automatically controls humidity levels by sensing both temperature and humidity in the room. This helps maintain a comfortable indoor environment. The unit requires regular refilling of the Water Tank with fresh tap water, and the Humidifying Tray and filter also need periodic cleaning to prevent mold, bacteria, and unpleasant odors.
The device offers various operating modes to suit different needs:
Additional features include a Child Lock to prevent unintended operation, an ON Timer to schedule when the unit starts, and an OFF Timer to schedule when it stops. The Front Display provides information such as humidity/temperature, wattage, timer settings, Plasmacluster Ion Light (blue), and Humidify Light (green for ON, off for OFF, red flashing for water needed). It also features an Odor Light, Dust Light, HAZE / PM2.5 Light, Motion Sensor indicator, and a Cleanliness Monitor that shows air purity in seven levels with color changes (blue for clean, red for impure).
Users can customize various settings, including Light Control (Auto, Darker, Turn off for display brightness), Sound Indicator Setting (beeping sound when water tank is empty), Auto Restart (resumes previous settings after power interruption), and Adjusting Sensor Sensitivity for Light, Dust (sensitive), Odor, and Motion sensors. The Motion Sensor sensing time can also be adjusted or canceled.
The air purifier is designed for ease of use with a clear operation panel and front display. The unit should always be operated in an upright position and placed on a level, stable surface with sufficient air circulation. When moving the unit, users should utilize the handles on both sides, remove the Water Tank and Humidifying Tray first, and move it slowly and horizontally on its casters. It is important not to move the unit while it is in operation.
For humidification, the Water Tank needs to be refilled with fresh tap water daily. To do this, the tank is removed, filled, and then securely re-installed. The Front Louver can be manually adjusted, especially during Plasmacluster Ion Spot Mode, to direct the airflow.
The device includes a caster stopper on the right and left casters to lock the unit in place. The filter installation process is straightforward, requiring the removal of the back panel, unwrapping of the HEPA and Deodorizing filters from their plastic bags, installing them in the correct order, and then re-installing the back panel. A tag on the HEPA filter indicates the correct orientation.
The unit is equipped with sensors that can be affected by direct wind, grease, oily smoke, or drastic temperature changes, so placement should consider these factors. For optimal dust collection, the unit should be placed at a distance from walls, and adjacent walls should be periodically cleaned as they may get dirty over time.
Regular maintenance is crucial for the optimal performance and longevity of the air purifier. The device includes a Filter Indicator light that turns on after approximately 720 hours of operation (30 days x 24 hours) to remind users to perform maintenance. After cleaning or replacing filters, this indicator needs to be reset by pressing and holding the FILTER RESET button for 3 seconds.
Maintenance tasks include:
The lifespan of the HEPA, Deodorizing, and Humidifying filters is approximately 10 years under specific usage conditions (e.g., purifying a room where 5 cigarettes are smoked per day). However, replacement may be needed more frequently in environments with significantly more severe conditions (e.g., HAZE). Replacement filter models are specified for each unit series.
The manual also provides troubleshooting tips for common issues, such as persistent odors, incorrect Cleanliness Monitor readings, unusual noises, and display errors, to help users identify and resolve problems before contacting service. For example, if the Front Display is off, it might be due to the Light control setting. If the Humidify Light does not illuminate when the tank is empty, it could indicate that the room has reached the appropriate humidity level or that the Humidifying Tray or filter needs cleaning or correct installation.
