I am an asthma sufferer who is allergic to pollen (big time) and
possibly to dust. I am trying to convert my (small) bedroom into an
"oasis" of clean air to sleep in. So far I've installed a fancy HEPA
filter that recirculates air, I made the windows and the doors air-
tight, and I moved all furniture/stuff out except for the bed. I
checked the air with a laser particle counter, and after 15 min of the
HEPA working at the highest speed the amount of ~1 micron particles in
the air goes down by a facor of 10 compared to the outside air. Great.

The problem is that I don't have any ventilation in the room. And I am
paranoid to leave the windows open. So I am thinking that perhaps the
HEPA recirculating filter I bought was a mistake, and perhaps I
should've installed some sort of a filter that takes the air from the
outside, filters teh air, and blows the air in. What would be the most
affordable way of doing that (under 1k?)? The room is about 12x16
feet, standard height. Wouldn't an outdoor HEPA require replacement
more often than an indoor HEPA? Besides, I rent my house, so, I can't
build/break walls and all that. Minimum impact preferred.

buffalo ny: asthma and house dust allergies for 30 years, but only
since age 30 [late blooming allergies]. beef allergy. lactose
intolerant. don't overlook exploring dietary sensitivities, that dairy
one was hard to diagnose in me for 2 years without starting over and
rebuilding foods eaten: from no food day one, add rice on day two, add
only one food item each day and monitor side effects.
i use the sharper image type of vertical ion generator, i bought the
walmart generic version of it after a friend showed me the real one
and recommended it; it will surprise you with the fresh air smell when
you walk into the bedroom. your concern for fresh air is valid, mine
is an air conditioner in the window with a small vent in it, a
10,000btu unit with remote. it may be your actual mattress, remove it
and change to plain full wave waterbed [no fabric or padding], heated
to a perfect skin temperature of 90F.
the temperature is critical, colder temp causes a stiff back and neck,
while warmer causes sweating. [i sold waterbeds and have slept on a
waterbed for 37 years. hot water wash all bedding. change bedding
materials type. it may be your dog, if you can wash him then rinse the
dog weekly, it will reduce dander, you may be sensitive to it and the
cat too. don't be discouraged. along with daily medications the
battle is won.
