Ah... such a simple sounding question. Wish there was a
simple answer to go with it.
I'm reading a book called "The Healthy Home Handbook" which has
some ideas. They list the major problems and then propose
solutions. Some examples:
asbestos - Avoid old building materials and products.
lead - Avoid old plumbing, paint, and products.
Radon - Test for and vent ground space if present.
Carbon Gases - Avoid fossil fuels or vent with care.
pollen - The book recommended filters, but there are
other ways. In this area the pollen occurs
at specific times of the year and day. By
avoiding the outside air during these periods
some control is achieved.
dust, mold - Control humidity and avoid fabric decorating
and clutter. Keep it clean and simple.
Organic
chemicals - Avoid petroleum based products and non-natural
compounds.
Most books recommend venting systems to control air quality and
humidity. There are lots of recommendations covering venting
products and air exchanges. This approach assumes the air inside
is bad and the outside air is much better. I prefer the approach of
fixing the inside air and not having to rely on frequent air exchanges.
Here are some ideas that are almost never mentioned in books
on house health:
1. Many of the Organic chemicals can be removed by plants.
2. Plants can be selected which do not have a large impact
on humidity.
3. The first 2-5 years after construction buildings may have
higher humidity (let them age before use).
4. The landscaping and house eves may have a big impact on
inside humidity. Also, the construction methods have a
big impact.
5. Aged dirt, straw, and wood can be good materials. Dirt can
be sealed and isn't always a source of dust or humidity.
6. Many dust and mold problems are created by our furnishings.
7. Air exchanges may be best in the early morning
while dust and pollen levels are low. This is speculation
and is what we do (spring, winter, and fall).
8. Humidity control can be combined with heating techniques.
Hot air holds more moisture and heating cold air creates
a drier environment.
9. On sunny days it is possible to dry a room with porous walls
and this dry state can be preserved for a long time. Assuming
few air exchanges and non-toxic interior. This works well with
solar heating.
