The short answer
The AQI runs from 0 to 500. Up to 50 is good, 51 to 100 moderate, 101 to 150 unhealthy for sensitive groups, and above 150 unhealthy for everyone. Check it like a weather forecast.
Air quality advice works best when it is targeted at the bedroom. You spend a third of your life there, breathing slowly, with the door often shut.
What it measures
Five pollutants: ground-level ozone, particle pollution, carbon monoxide, sulfur dioxide and nitrogen dioxide.
The groups most affected by poor air are children, older adults, pregnant women and anyone with heart or lung conditions. Households that include them should treat these steps as priorities, not extras.
Which number matters to you
For most people it is PM2.5 and ozone. Ozone peaks on hot sunny afternoons; particles spike with smoke and winter inversions.
Small, permanent changes beat heroic one-off efforts. A purifier that runs quietly every night does more than a deep clean twice a year.

Americans spend close to 90 percent of their time indoors, according to the EPA. That single figure explains why indoor air deserves more attention than it usually gets in conversations about lung health.
Acting on it
Move exercise to the morning or indoors on bad days and keep windows closed.
You do not need expensive equipment to start. A twenty-dollar hygrometer and the free AQI reading on your phone tell you most of what you need to make sensible daily decisions.
A quick checklist
- Check the AQI before outdoor exercise.
- Run the range hood every time you cook.
- Put a HEPA purifier in the bedroom.
- Measure humidity with a hygrometer.
- Wash bedding weekly in hot water.
Low-cost PM2.5 monitors have become reasonably accurate for home use. Watching the number jump while frying dinner is often the nudge people need to switch on the range hood.
Putting it into practice
No supplement filters the air you breathe. We make a respiratory spray and we still put ventilation, filtration and source control far ahead of it, because that is the order the evidence supports.
If you share your home, talk these ideas through with the people you live with. Breathing-friendly changes such as ventilation, humidity and smoke-free rules work best as household decisions, and they benefit everyone, children and older relatives most of all.
Where BreathiZen fits
Since you are on the BreathiZen official website, here is how our spray relates to this subject: indirectly. It is formulated to support respiratory wellness and immune health in healthy adults, it contains no caffeine, and it takes about five seconds a day. It is one supporting habit among the several described above.
Common questions
Can a supplement protect me from pollution?
No. Reducing exposure is what protects you. A spray like BreathiZen only supports everyday airway comfort.
What is a healthy indoor humidity?
Between 30 and 50 percent relative humidity.
Where do I check air quality?
AirNow.gov or your phone's weather app shows the local AQI.
Key takeaway
To sum up: The AQI runs from 0 to 500. Nothing here is complicated, and consistency matters more than intensity.
Please read before you order. BreathiZen is swallowed, not inhaled, and it is never a rescue inhaler. Keep using any medicine your doctor prescribed. Ginger can add to the effect of blood-thinning medicine, so ask your prescriber first if you take warfarin, apixaban, clopidogrel or daily aspirin. See a doctor promptly for breathlessness, wheezing or a cough that lasts more than three weeks.
