What is House Dust?
House dust is fine particles of dust almost invisible to the naked eye, and you can definitely find it in your home as well.
It may even cause your health to deteriorate without you knowing it. Here is the right knowledge about house dust, and share some appropriate measures you can take against it.
It is Everywhere, Even in Your Home
Even if it looks clean at a glance, house dust is accumulated in many places. Since the particles are extremely small and lightweight, human movements blow them into the air and cause them to move around.
Dust Invisible to the Human Eye
House dust includes both dust that comes in from outside and dust that is generated inside the house.
Pollen and sand particles can enter through windows and doors on the wind, or be brought in on our clothes. One of the most common types of dust generated in the house are dust mites that favor bedding and carpets. There also are molds, human dandruff, pet hair, dust mite remains, and dust mite feces. Since they are also food for mites, they need to be cleaned before they accumulate.
It Can Cause Sickness and Allergy
Because house dust particles are extremely small, they easily get blown into the air. When inhaled, they can trigger allergy symptoms.
Ways to Clean House Dust
Human eyes cannot see most of the house dust no matter how bright the room is. The house dust sensor detects even such invisible dust of 0.02mm and alerts you of such residues via the indicator lamp.
Suction Power Automatically Increases When the Lamp Flashes!
The red lamp flashes when house dust is detected. Focusing on the areas where the indicator turns red lets you clean efficiently, resulting in longer battery life. The indicator turns blue when the area becomes clean.
*Lamp turns off instead of blue in some models
A high-speed infrared sensor in the vacuum cleaner detects even the dust as small as 20μm (0.02mm) that cannot be seen by the human eye.
The House Dust Sensor Prevents Leaving Dust Behind!
Comparison of dust vacuumed with and without house dust sensor
Keeping an eye on the house dust sensor display while cleaning will prevent any leftover particles. When compared to cleaning without a house dust sensor, results showed that 1.7x more fine dust was vacuumed when using the house dust sensor.*2
