Allergy-Sensitive Comfort engineering anchor: allergy HVAC filtration Los Angeles
Allergy-sensitive HVAC engineering reduces airborne particulate exposure through measured filtration efficiency rather than marketing claims. Common allergen sources in LA: outdoor pollen (oak, ragweed, olive — peak February through May), pet dander (year-round), dust mite fecal matter (humidity-dependent), and outdoor PM2.5 (traffic-corridor and wildfire-related). MERV 13 captures most particulate in the E1 (0.3–1 µm, ≥50%) and E2 (1–3 µm, ≥85%) bands per ASHRAE 52.2-2017. The scope avoids bipolar ionization and ozone-generating ionizers (CARB caps at 0.050 ppm; many fail in real-room conditions) and emphasizes verifiable particle-capture math. We do not make medical claims; medical management of allergies belongs with the clinician.
