Single-hose units create negative pressure — drawing unconditioned outdoor air (and outdoor pollutants) into the room through gaps. Condensate collection pan and internal coils develop mold and bacterial biofilm if not cleaned regularly. Recirculated air passes over potentially contaminated evaporator coils. Less efficient than window or mini-split units.","synthesis":{"derived_risk_level":"extreme","synthesis_confidence":0.757,"synthesis_method":"compound_composition","context_used":"human_child","context_source":"product_users","exposure_modifier":1.265,"vulnerability_escalated":false,"escalation_reason":null,"compounds_resolved":1,"compounds_total":1,"synthesis_date":"2026-05-09","synthesis_version":"1.2.0","methodology_note":"exposure_modifier and adjusted_magnitude are computed from ALETHEIA-calibrated heuristics (route × duration × frequency multipliers, clamped to [0.5, 1.4]).
