San Diego County’s $26.8 Million Air Purifier Contract Faces Legal Challenge
5/17/2026, 11:58:15 PM
Core Dispute Over Air Purifier Procurement
San Diego County awarded a $26.8 million contract to Oransi LLC for tens of thousands of portable air purifiers intended to mitigate hydrogen sulfide and other gases released from the polluted Tijuana River. Medify Air, which had submitted a higher-priced bid of $27.1 million, filed a non-conformed complaint seeking to void the award, arguing that the county’s solicitation lacked clear performance metrics and that the selected units would not meet noise or air-quality standards. The lawsuit asks a judge to order the county to abandon the contract and restart the bidding process.
Background: Tijuana River Pollution and Air-Quality Concerns
The Tijuana River, flowing near the Saturn Boulevard hotspot in Imperial Beach, carries severely polluted water that releases noxious hydrogen sulfide gas. The county’s plan to distribute 30,000 air purifiers is described as a temporary, partial solution while U.S. and Mexican authorities address aging infrastructure at the trans-border water-treatment plant. Past attempts have faltered; in 2025 county workers retrieved 400 purifiers because they lacked the necessary filters to clean toxic gases.
Key Parties Involved
- San Diego County – the contracting public agency responsible for the procurement.
- Oransi LLC – the low-bid winner of the $26.8 million contract.
- Medify Air – the competing vendor alleging procurement irregularities.
- Tijuana River Valley residents and South Bay businesses – the intended beneficiaries of the air-purifier distribution.
Financial and Operational Details
- Contract value: $26.8 million (Oransi) vs. $27.1 million (Medify).
- Planned distribution: 30,000 portable units.
- Prior distribution failure: 400 units lacking potassium permanganate and charcoal filters.
- County’s stated goal: provide interim relief from hydrogen sulfide while long-term infrastructure upgrades proceed.
Official Statements & Responses
San Diego County declined to comment on the lawsuit, citing the pending litigation. Medify Air’s petition asserts that the county “ignored” data and “abused its discretion” by selecting the lower bid without a measurable compliance framework.
Criticism & Opposition
Medify Air contends that the county’s solicitation used vague language and imposed mandatory performance requirements without defining verification methods. The company also argues that the selected purifiers will not satisfy established noise and air-pollution guidelines, rendering the award “unsupported by substantial evidence.”
Conflicting Reports & Gaps
- The county’s procurement documents do not specify how purifier performance will be measured, creating uncertainty about compliance verification.
- No independent testing results have been released to confirm whether the Oransi units can effectively filter hydrogen sulfide or meet the noise standards cited in the contract.
- The county’s refusal to comment leaves the factual basis of the lawsuit uncorroborated by the awarding agency.

What’s Next
Medify Air is seeking a judicial order to terminate the Oransi contract and reopen bidding. The outcome will determine whether the county proceeds with the current purifier rollout or revises its procurement strategy amid ongoing concerns about air quality in the Tijuana River Valley.
