San Diego, CA
San Diego County’s Air Improvement Relief Effort (AIRE) program has successfully distributed over 10,000 air purifiers to households in the South Bay area, aiming to mitigate the health impacts of hydrogen sulfide odors.
Program Overview
Initiated in February 2025, the AIRE program provides free air purifiers equipped with activated carbon and potassium permanganate filters to residents in San Diego and Imperial Beach. These filters are designed to reduce hydrogen sulfide—a colorless gas with a strong odor similar to rotten eggs—present in indoor air due to cross-border wastewater and sewage flows. Each household receives one air purifier and up to two replacement filters.
Impact and Expansion
By January 2026, the program had reached its 10,000-unit milestone, marking a significant achievement in supporting South Bay residents affected by hydrogen sulfide odors. In response to ongoing demand, the San Diego County Air Pollution Control District allocated an additional $1 million to provide approximately 3,500 more purifiers to eligible households.
Health Concerns and Community Response
Elevated levels of hydrogen sulfide have been linked to various health issues, including headaches, nausea, and respiratory symptoms. A study by UC San Diego’s Scripps Institution of Oceanography and other institutions found that high concentrations of this toxic gas are entering homes and affecting residents’ health. The AIRE program aims to alleviate these health risks by improving indoor air quality.
Program Eligibility and Application
Residents in the City of San Diego communities of Otay Mesa West, San Ysidro, Egger Highlands, Nestor, and Tijuana River Valley, as well as the City of Imperial Beach, are eligible to apply for the AIRE program. Applications can be submitted online, and proof of residency is required. For more information, visit the San Diego County Air Pollution Control District’s website.
Background Context
The Tijuana River Valley has long been affected by pollution, leading to the release of hydrogen sulfide into the air. This environmental issue has prompted local authorities to implement measures like the AIRE program to protect public health and improve air quality in the region.
