I don't know if you have noticed

If the house is not cleaned for two days

There will be a layer of dust on the floor

At this time, some people were puzzled.

The windows were clearly closed tightly.

How does dust get in?

Come and see

turn out to be

Most dust comes from the home.

Only a small part comes from outdoor

First of all,

After metabolism, the body

Some dead epidermal cells and hair will fall off

followed by

Bedding manufacturing

When making the bed and folding the quilt

The fibers on them will fall off.

Mixed with dust, it becomes

The "Maomao" we often see

And also

Electrical appliances

Like TV, computer, air conditioner

Static electricity will be generated during use

Accumulation of dust

in addition

Some dust was brought back from outside

If you don't change your clothes when you get home

Sitting on the bed sofa

This requires regular cleaning

But when cleaning

Don't overuse chemical disinfectants

Excessive sterility may lead to

Increased risk of allergic diseases
