Does using an air purifier reduce dust a lot?

I write it thinking that it's less than nothing.

It doesn't get as dusty as I thought.
You just vacuum the dust.

Many people expect a lot from the air purifier, but it's better not to expect much from the performance.
Cleaning more often is better for dust removal.
