The start of a solid plan to control indoor pollutants always includes the following steps:
- Test for radon and fix if a problem
- Reduce asthma triggers (mold, dust, mites)
- Forbid smoking indoors
- Keep all areas clean and dry (remove mold and excess moisture)
- Always ventilate when using products that release fumes/pollutants (close tightly, store outside house)
- Inspect fuel-burning appliances for leaks
- Install a carbon monoxide alarm
