Understanding air quality in New York
New York's outdoor air is shaped mainly by traffic emissions, building heating (oil/gas), construction dust. These climb during rush hours and settled, still weather when pollutants aren't dispersed — which is why local agencies monitor them closely and enforce the rules above.
Whatever today's AQI shows on the live data, the air inside your home is typically 2–5× more polluted than outdoors, and it's the part you can actually control. Sizing a MERV‑13 or HEPA purifier to your room is the most reliable way to protect New York households on high‑pollution and wildfire‑smoke days — use the free ACH calculator to get the size right.
Outdoor Air in New York Is Hard to Change. Indoor Air Isn't.
The EPA says indoor air can be 2-5x more polluted than outside. For New York residents, the most effective long-term solution is a quality indoor air purifier — removing 90%+ of PM2.5, allergens, and pollutants where you spend most of your time.
