Yellow dust comes back!

I remember my friends from Germany or Spain asked me why many Asian people take wear masks.
They wondered if we have mysophobia.

But no, I think it's necessary to use it wear them.
Especially in spring, the sky is yellow, and weather forecasters suggests recommend that we use us to have special masks.

Of course not everybody on the street have it wears one, so (fortunately) we don't seem like clones XD
Though I'm not happy with this air pollution :'(

corrections  suggestions

I changed "necessary to use" to "necessary to wear" because I prefer it here.  Of course "use" is correct, though.  "wear one" instead of "wear them" is ok too.  

Of course not everybody on the street have it  "Have" is wrong most importantly because it should be singular "not everybody...has one". I also prefer to use "wear" because "have" means own. As you inlcuded, "on the street" it sounds awkward as if this location is has a cause/ effect relationship on who owns one and who doesn't.

If you meant "own" and want to keep "on the street" this sounds better: Of course not everybody has one, so fortunately we don't all look like clones on the street.

Though I'm not happy with this air pollution This is a sentence fragment.  It might be what you intended so I didn't correct it.  :)

Recently I saw a news broadcast about the yellow hazy sky looming over Seoul.  Doesn't it hurt your eyes as well? Even though it is winter, I know that some people like to crack windows to let in fresh air or perhaps in some cases protect themselves from CO2 during the cold winter months. Even inside, I am sure there is little escape from the thick dust. :(
