FWIW, a *true* HEPA filter in a resi setting is a waste of
money....True HEPA filters get used in clean rooms and such.
THey are 95%+ efficient....in a resi setting, your gonna get a
whole lot more dust and dirt than a HEPA filter can handle just
by infiltration of outside air, and the system has to be
specially designed for HEPA filters.

I have to disagree just a little bit. My ex had a hard time
sleeping, especially during the fall and winter. She was always
waking up with a sore throat and bleary eyes. I bought a Sears
room-size HEPA filter and it really helped a lot. It even
disappeared the dust bunnies under the bed. The only drawback was
the filters. It would take a new one every couple of months, and
those suckers cost over $25 a piece (probably $50 by now). About a
year later I happened to run across the high-efficiency furnace
filters on sale at my local big box store and tried one. Man, did
that make a difference! The whole house had almost no dust, and
the HEPA filter in the bedroom unit would last for six months or
more. I did the same at my mom's house after I moved in to take
care of her after Dad died. I am sold!
