Indoor Air Quality in Las Vegas, NV
Las Vegas air quality has 3 problem windows: Mojave dust year-round, wildfire smoke drifting in from California in August and September, and trapped winter inversions between the Spring Mountains and McCullough Range. CheckedHomePros routes IAQ work to NSCB C-21 pros who upgrade the filter cabinet to a 4-inch media filter at MERV 13 (April Aire 413, Honeywell F200), add a UV-C light (Honeywell UV2400U, Reme Halo LED) at the coil face, and verify the air handler can handle the added static pressure.
What indoor air quality actually involves
Filter cabinet upgrade to 4-inch media (April Aire 413, Honeywell F200, or Lennox PCO-20U).
MERV 11 or MERV 13 filtration (MERV 13 captures 0.3 to 1 micron particles, including wildfire smoke).
Static pressure measurement before and after to verify the air handler can drive the new filter.
Optional UV-C light at the coil face (Honeywell UV2400U or Reme Halo LED) for coil biofilm and airborne pathogens.
Optional HEPA bypass filter for households with severe asthma or COPD.
Humidifier or dehumidifier for the monsoon humidity surge weeks.
Las Vegas-specific things to know
- MERV 13 dropped into an air handler designed for MERV 8, killing airflow and freezing the coil within 30 days.
- UV-C light installed without checking that the lamp does not hit plastic plenum components, which degrades them in 6 to 12 months.
- Standalone HEPA marketed as a whole-house solution, where coverage is only the room it sits in.
- Ozone-generating air purifiers (some Ionic Pro variants) which violate California ARB rules and are generally a bad idea.
- Whole-house humidifier installed without dehumidifier control, raising indoor RH above 60% during monsoon and growing mold at registers.
