The short answer
True HEPA purifiers capture at least 99.97 percent of particles 0.3 microns in size, including dust, pollen and smoke. Sized correctly for the room and run continuously, they measurably reduce indoor particles.
The EPA's approach to indoor air comes down to three steps: control the source, ventilate, and clean the air. Removing a pollutant beats filtering it, and filtering it beats breathing it.
What HEPA means
A certified filter standard, not a marketing word. Look for true HEPA rather than HEPA-type.
Small changes compound. Running a range hood, washing bedding weekly and keeping humidity in range each cut exposure a little; together they transform the air in a home over a year.
Sizing
Check the clean air delivery rate against your room size; undersized units do little.
You cannot see most of what matters in indoor air. Fine particles, gases and allergens are invisible, which is why an inexpensive monitor or hygrometer often changes habits more than advice alone.

Put it in the bedroom, away from walls, and run it continuously on a quiet setting.
Ventilation is free. Opening windows on the side of the house away from traffic when outdoor air is good refreshes indoor air in minutes.
What it cannot do
Purifiers do not remove gases well unless they have a substantial carbon filter, and they do not replace ventilation.
If someone in the home smokes, no purifier can fully compensate. A completely smoke-free home and car is the single most protective rule.
A quick checklist
- Keep humidity between 30 and 50 percent.
- Place a true HEPA purifier in the bedroom.
- Wash bedding weekly in hot water.
- Check the air quality index before outdoor exercise.
- Skip scented candles and air fresheners.
Americans spend about 90 percent of their time indoors, according to the EPA, and indoor pollutant levels can be two to five times higher than outdoors. That makes the home one of the easiest places to make a real difference to what your lungs breathe.
Putting it into practice
Older adults, young children and people with heart or lung conditions are most sensitive to poor air quality, so household changes often benefit the most vulnerable people in the home.
Living with others? Share these ideas with your household first. Changes to air, humidity and smoke rules work best as household decisions, and they help everyone, especially children and older relatives.
Where Lungora fits
We make Lungora, and we are careful about how we connect it to subjects like this one. It does not treat any condition discussed here. What it offers is daily support for antioxidant defense, circulation and energy, explained in full on our Lungora ingredients page. You may also like our page on how Lungora works.
Common questions
What is the most important indoor air change?
Keeping the home completely smoke-free.
How often should I change purifier filters?
Follow the manufacturer's schedule, usually every 6 to 12 months for HEPA filters.
What humidity is best?
Between 30 and 50 percent for most homes.
Key takeaway
To sum up: True HEPA purifiers capture at least 99.97 percent of particles 0.3 microns in size, including dust, pollen and smoke. Nothing here is complicated, and consistency beats intensity.
Before you order, please read this. Lungora is a dietary supplement, not a treatment for any lung disease, and it never replaces an inhaler, oxygen or prescribed medicine. Turmeric and CoQ10 can affect blood thinners such as warfarin, alpha lipoic acid can lower blood sugar, and butcher's broom can raise blood pressure, so ask your doctor or pharmacist first if any of those apply to you. Shortness of breath, wheezing, chest pain or a cough lasting more than three weeks needs a medical check.
