Default positive pressure and air filtration

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.

Hi,
Do you use puffer? Do you drink milk? Do you control your diet to
minimize the suffering? Do you do regular whole body cleansing to
increase the allergen tolerance? Ever tried a supplement called Ivy
Calm(American Ivy extract in syrup form; made in Swiss). I became a
chartered Herbalist to help my son was born with a bad case of asthma.
He used to carry puffer until about 10 years old, now at 23 he is
normal. He plays ice hockey, saxophone. Diet played a BIG part of making
him out of asthma. There are many, many good natural supplements.
Nature's Way makes product called HAS, there is another one, Bronchial
formula by Dr. Christopher out of Utah. Ever tried things like these?

Thanks for the comment. I don't want to go in that direction. In
short, yes, I know enough about drugs and nutrition. This is not an
asthma group. I mentioned asthma just to explain why I need what I was
asking about.

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.
lots of reading for you at:

now just found filters with pollen counts at:

What is that air conditioner in the window with a small vent in it, a
10,000btu unit with remote? Does it have a filter in it?

Not sure if the heating of the bed is a good idea. Sounds like a
breeding ground for the mites. But the fact that it's washable is a
plus. The fact that you used to sell beds does not help

You have done a lot of good things. I think you got the right filter to
start with. I assure you that you have not totally sealed the room. You
don't really want to do that anyway since it would mean no oxygen. :-)

How is the room heated and/or cooled?

I'm not sure you'll find a through-the-window HEPA filter, but I think
you could jerry-rig one easy enough. Building a small, light frame
that is the same size as a filter and put it in your window and seal
it up. Then put a fan on the inside to suck the air in through the
filter. Then run the inside the room filter, too. Run the window
filter 24/7.

There are many industrial applications of positive pressure of
filtered air including clean rooms and dark rooms. By obtaining
positive pressure, it will blow dust and dirt OUT of the house. When
you open a door, air goes out instead of in -- so the dust and dirt
doesn't come in as easily. You might want to consider putting the
whole house under positive pressure. You don't need much pressure to
be effective -- I'd guess nearly any pressure at all would work. The
trick is to filter the air, force it in, but don't give it an exit so
it (a) pressurizes and (b) goes out through the natural cracks and
stuff where the air would normally be coming in.

Personally, I think you're on the right track. Filtering the air
BEFORE it gets in the room is probably better than filtering it once
it is in the room.

Good luck with it.

This is what I was thinking, but I was not sure how strong of a fan I
need to suck through a HEPA. After all, a HEPA may be an overkill.
Also, since complete filters are so expensive I was thinking may be
there is more to them than just a fan and a filter.

I need no cooling (I am in the Bay area) and I heat it with a portable
oil heater.

I don't know. HEPA filters are everywhere, ranging from your vaccuum
cleaner to the air duct of my van (hmmm. I should see if it needs
changing).

If I were doing the project, I'd get one of those two-fan units that
are made to go into a window (and the window closes on it for a
seal).
This is typical and I found it quick on froogle.

but you can get them everywhere.

I think I'd buy a HEPA filter that is larger than that -- say for a
furnace or some stand-up filter -- and cut it to the same size. Then
build a cardboard or wood frame for it, glue/tape it all together and
give it a try. For $50 to $100 you'd know if it worked or not.
