I recently returned home after an episode of emphysema and would now
like to provide the cleanest and the best possible air for my home
breathing. I live in Florida and my air conditioner runs constantly at
77 degrees. What is the best possible system for my home?

Get a HEPA filter. They're made specifically for this.

Air conditioners remove the humidity from the air. HEPA filters remove
any particles in the air. The only other thing you could do beyond
this is use activated carbon as well, which would remove chemicals
from the air, but that's a little overkill.


Since you're going to be spending SEVERAL HUNDRED dollars on a HEPA
filter for a house, I highly recommend you visit a local dealership,
to ensure that you'll get one that will match your house.

I put in an over the counter filter that took out small particles and
my air- conditioning costs doubled until I took it out. I decided that
I needed much more filter area, which no standard filter could
provide. The cheapest way is to filter the air in the room you stay in
with an in-room HEPA filter. If you want to use a whole house filter
it needs to be specially constructed with a large surface area, if you
desire low air-conditioning costs. This filter or filter box will not
fit your existing air conditioner. Search the Internet for HEPA filter
manufacturers or have a specialist who knows what he/she is doing, to
work with you. If you smoke you need to stop or figure out how you
have caused your medical problem, in the first place. Most of us cause
our own sickness. Good luck.
