Dust in the air is often small enough that it stays aloft. When the raindrops hits (impinges on) the particulate it it wets and entrains them (as particulate in the drops) The droplets with the entrained dust particles are heavy enough to fall down along with the raindrops, reducing the dust particles or even eliminating them all from the air stream.
This is the same principle as used in dust removal systems in industrial systems (wet scrubbers) where a artificial rain of droplets flows countercurrent to a dusty gas stream to remove the dust and/or soluble chemical droplets.

How does rain helps in making the air clean after a dust storm?
The water droplets will mix with the dust particles and bring the dust to earth, leaving the air less dusty.
What are dust Storms?
A dust storm is a strong and violent wind that carries silt, clay, dust, and other particles that can travel in the air for long distances.
What is represent dust in the atmosphere?
Dust particles are an important component of the atmosphere because they affect us in several ways. They often provide nuclei on which raindrops can form. They can cause breathing difficulties especially in asthmatic people. They also affect the amount of solar radiation which reaches the surface. Volcanic eruptions throw so much dust into the air that they can cause global cooling.
Why does dust float in air?
whether DUST floats around, I suggest you read about Brownian motion. In a nutshell, it is well-established that particles suspended in a fluid (in this case, dust suspended in air) exhibit constant, random motion. Dust particles will eventually settle to the surface due to gravity, but any disturbance can kick them up again, and particles can remain suspended for very long times (the lighter the particle, the longer it can remain suspended).
Besides water vapor what must be present for a cloud to form?
Solid particles such as dust and water vapors, without either of these, there would be no clouds.
What is an air particle?
dust particles
If I get an air purifier will that reduce my need to vacuum and dust for allergy purposes?
It will not vacuum or dust for you.It only cleans small particles from the air.Your house will be clean,but it won't be like you bought Rosie from the Jetsons.
How does dust in the air interact with water vapor in the air?
Water condenses around dust particles and becomes clouds.
What are two nongaseous particles in air?
pollen, dust, soot
What does air ordinarily contain?
Dust and other particles of matter.
Why After a dust storm how does rain helps in cleaning the air?
The water droplets will mix with the dust particles and bring the dust to earth, leaving the air less dusty.
What is an air filter?
A device that is made to remove tiny particles of dust from the incoming air.
Does air scratch video games?
Air itself cannot, but fine particles of dust in the air might.
What moistens the air and filtiters dust particles?
The Nose/nasal passages.
How do particles of salt and dust in the air affect the formation of clouds?
baho
What do water droplets form on to create clouds?
Dust particles in the air.
What warms moistens and filters air and dust particles?
The Nostrils or the Nose.
