OPERATION MANUAL.

KI-N40 Air Purifier with Humidifying Function

“Plasmacluster” and “Device of a cluster of grapes” are registered trademarks of Sharp Corporation in Japan, Philippines and elsewhere.

The number in this technology mark indicates an approximate number of ions supplied into air of 1 cm3, which is measured around the center of a room applicable floor area (at 1.2 m height above the floor) when the product is placed close to a wall at the MED mode setting.
Thank you for purchasing this SHARP Air Purifier.
Please read this manual carefully before using the product.
This manual should be kept in a safe place for handy reference.
Please Read Before Operating Your Air Purifier

The air purifier draws in room air through the air inlet, circulates it through a Pre-Filter, a Deodorizing Filter and a HEPA Filter inside the product, and then discharges it through the air outlet.
The HEPA Filter can remove 99.97% of dust particles as small as 0.3 microns that pass through the filter and also helps absorb odors.
The Deodorizing Filter gradually absorbs odors as they pass through the filter.
Some odors absorbed by the filters will break down over time, causing additional odors. Depending on usage conditions, and especially if the product is used in environments significantly more severe than a normal household, these odors may become noticeable sooner than expected. If these odors persist, replace the filters.

The illustration in this instruction manual is KI-N40.

When minerals in tap water adhere to the filters and become hard and white, they absorb odors in the room that can cause the emission of an unpleasant odor when the Humidifying Filter is dry. (Varies depending on water quality and other environmental factors.)
If this occurs, perform the Humidifying Filter maintenance. (Page 20)

NOTE

The air purifier is designed to remove air-suspended dust and the odors.
The air purifier is not designed to remove harmful gases such as carbon monoxide contained in cigarette smoke.
The air purifier may not completely remove an odor if the source of the odor is still present.

FEATURES

A unique Combination of Air Treatment Technologies
Triple Filtration System + Humidification + Plasmacluster

Plasmacluster
High Density Plasmacluster 25000
The higher the PCI density is, the more effective PCI has.
By emitting a balance of positive and negative ions, Plasmacluster air treatment is a natural process.

Triple Filtration System + Humidification
TRAPS DUST
Pre-filter traps dust larger than approx 240 micron particles.
DECREASES ODORS
Deodorizing filter absorbs many common household odors.
REDUCES TINY DUST, POLLEN & MOLD
HEPA filter traps 99.97% of particles as small as 0.3 microns.
HUMIDIFIES
Controls humidity by sensing temperature and humidity automatically.
Unique Airflow
Powerful air suction and unique airflow quickly and efficiently collect dust and other particles.

SHARP KI N40 Air Purifier with Humidifying Function - Unique
Airflow

Faster airflow at a 20º angle causes dust to be collected at lower levels in the room for more effective cleaning.
Plasmacluster can remove static electricity and can thus prevent dust from attaching to walls and other surfaces.

Wi-Fi Function

Confirms that the air quality of the room has become clean visually.
Controls the product through smart devices such as a remote control.
Proposes optimal timing for filter exchange.

1: According to Japan Electrical Manufacturers’ Association JEM 1467, the Max service life is based on the equivalent condition of the smoke from 5 cigarettes per day whereby the dust collection/deodorization power is reduced by half compared with that of a new filter. It is recommended to replace the filter more frequently under more severe conditions.
2: Designated App notifies when each replacement part should be replaced according to usage.
Filter life varies depending on the room environment, usage conditions, and location of the product. We recommend replacing the filter more frequently if the product is used in conditions significantly more severe (PM2.5 etc.,) than a normal household.

MAINTENANCE
Remove the dust on the filters.
NOTE

Do not wash the filters. Do not expose to sunlight (Otherwise these filters may lose their efficacy.)

HEPA FILTER
Maintain and clean only the tagged surface. Do not clean the opposite surface.
The filter is fragile, so be careful not to apply too much pressure.

DEODORIZING FILTER
Both surfaces can be maintained and cleaned.
The filter is fragile, so be careful not to apply too much pressure.

Some odors absorbed by the filters will break down over time, causing additional odors. Depending on usage conditions, and especially if the product is used in environments significantly more severe than a normal household, these odors may become noticeable sooner than expected.
Replace the filter in those cases or if dust is unable to be removed after maintenance.

REPLACEMENT
See page 9 for directions on how to install the filter when replacing.

Please consult your dealer for purchase of replacement filter.
Use only the filter designed for this product.
It is recommended that you note down the date when the filters were replaced for future reference.
