There's a ton of good stuff on this all over the 'net.  I'd google
it.  Here's a source or two to get you started:

Good luck!  I've really never noticed any substantive difference with
anything except particularly low humidity ... and I've lived in a
number of places and traveled to a great many.

Much worse, in fact.

Yes, it can.  There is a condition called "non-allergic rhinitis," which
is inflammation caused by the irritation rather than a true allergic
reaction.  But it's also indoor chemicals.  Even electronic gear, like
laser printers, can outgas when they get warm if they are not well
ventilated.

Open a window.
Fresh air is the best solution, because it totally changes out the air
in your home.

When I was a kid, my mom always kept a window slightly ajar even in the
coldest part of the winter.  Pay a little more on your heating bill,
stay healthier and avoid medical bills.

The second best solution is to aggressively remove all the sources of
dust, mold and chemical irritants.  Step One:  Get rid of your
wall-to-wall carpets.  Install tile or linoleum or wood parquet flooring.

Air filters really aren't that effective.  They cannot filter out the
chemical fumes from household chemicals, paints, resins on electronic
circuit boards, etc.  Just open a window and get some fresh air inside.
