About

IVAN Air

Features
Read full description

IVAN Air puts real-time air quality from the Imperial Valley's community monitoring network in your pocket. See how clean — or unhealthy — the air is right now at monitors across the region, and get notified the moment the air near you takes a turn. Built on the IVAN (Identifying Violations Affecting Neighborhoods) network operated by Comité Cívico del Valle, IVAN Air brings together readings from Dylos, SLX, Trinity, and CERCA monitors into one simple, color-coded view. WHAT YOU CAN DO • List view — every monitor with its current reading, sorted so the worst air is easy to spot. Sort by nearest to you. • Map view — all monitors on a live map, with nearby ones grouped so dense areas stay readable. Tap any monitor for full details. • Monitor detail — current AQI or CAL reading, color-coded categories, and health recommendations. • Favorites — star the monitors you care about and filter the list and map to just those. • Push alerts — pick the monitors and the air-quality level that matter to you, and we'll send a notification when one reaches it, even when the app is closed. Set separate levels for AQI and CAL monitors. COLOR-CODED, AT A GLANCE Readings use the familiar EPA Air Quality Index (AQI) scale and the CAL scale, with the same green-to-maroon colors you see on official air-quality maps, so a number always means something. PRIVACY-FIRST No account required. No ads. No third-party tracking. Your location, if you allow it, is used only on your device to find nearby monitors. IVAN Air is a free, community-driven tool to help Imperial Valley residents understand and act on the air they breathe.
