How can I improve my home air quality without expensive equipment or supplements?

I've spent decades with my body in different spaces, and what I notice is this: the simplest shifts often matter most. Start with what you already have. Open windows during cooler parts of the day—even ten minutes changes the breath in a room. Plants aren't magic, but they're honest helpers; a few in corners where you spend time soften the air slightly. Notice dust gathering on surfaces and wipe it gently—this is embodied care, not chore. If cooking creates heavy air, crack a window. If you live near traffic, keep that window closed during peak hours instead. The real work is paying attention to how your body responds to different times of day, different rooms. When you breathe easier, you'll know. That feeling is your teacher. Sometimes the most expensive solution isn't the truest one.
