NOTE
• The dust concentration may vary depending on the environmental conditions (for example, when the
product is near a construction site, road, or fabric sofa, or when a vacuum cleaner is used or bedding and
clothes are arranged near the product, etc.).
• The following conditions may cause temporarily high readings of PM level:
–
When the product is used near fur rugs or used in vets, clothes stores, or other places prone to high
humidity, smoke or infestation
–
When humidifiers, electric pressure cookers, sprayers and such are being used in the same room
–
When the product is used where there is inflow of outside air with dust or other types of air pollution
(e.g. proximity to the building’s HVAC or ventilation systems, or loose window frames)
• The gas pollution reading can be affected by odorous household items such as air fresheners, deodorants
and detergents.
• If you are using more than one air purifier in the same room, the dust concentration reading on each unit
may not be same as they affect air circulation. The dust concentration reading may vary depending on the
sensor or product being used.
• If there is no change in the intensity of gas (odour), it may not be reflected in the gas pollution reading
even though you can clearly smell it.
• PM levels on the display may differ from the official forecasts.
• Nearby electromagnetic waves or electrical noises may cause temporarily high readings of PM level.
