Protecting yourself during heat waves, high humidity and pollution

Hello everyone. I have a chronic lung cancer and have had 6 tumors removed. I have lost a lot of lung tissue so my breathing in very hot, humid and polluted air is limited to the activities that I do comfortably and where and if I go anywhere.
Today in southern Rhode Island, where I live, the air the air quality is horrible do to the high particulates, actual particles from fossil fuel users. They are carried by the movement of out planet and the jet streams. Today it's suppose to be near 100 F and the air this AM has fogged the windows up quite a bit because I have AC with hepa filters.
It's imperative to protect yourself against these elements if you have lung cancer or lung issues. If you have lung issues of any kind keep your house comfortable cool so that you can inhale and exhale without working hard. For those people who need O2 you might, if you haven't already, ask your doctor if you should increase the level of air if need be.
Draw curtains and shades and make sure that all doors and window are shut and stay closed to avoid unnecessary solar and heat gain.
Hopefully all of your filters for keeping your air clean have been cleaned recently. If not please do so before the next bad weather hits.
Have your rescue inhalers and regular inhalers handy and use them if necessary. GO to the ER or someplace that has air conditioning if you lose power.
STAY inside and cancel all unimportant appointments. People and doctors will understand.
This is what the American Lung Association recommends:
The American Lung Association encourages everyone to get involved in the fight for cleaner, healthier air. Here are some simple, effective tips for protecting you and your family from the dangers of air pollution:

Check daily air pollution forecasts in your area. The color-coded forecasts can let you know when the air is unhealthy in your community. Sources include local radio and TV weather reports, newspapers and online at airnow.gov.
Avoid exercising outdoors when pollution levels are high. When the air is bad, walk indoors in a shopping mall or gym or use an exercise machine. Limit the amount of time your child spends playing outdoors if the air quality is unhealthy.
Always avoid exercising near high-traffic areas. Even when air quality forecasts are green, the vehicles on busy highways can create high pollution levels up to one-third a mile away.
