Understanding air quality in Las Vegas
Las Vegas's outdoor air is shaped mainly by desert and construction dust (pm10), ground-level ozone, vehicle emissions. 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 Las Vegas households on high‑pollution and wildfire‑smoke days — use the free ACH calculator to get the size right.
