Unverified82% confidenceDecision RuleTime unknown
带过滤功能的窗式通风器优先选可拆洗初效+可更换G4/F7滤芯配置；F7级（≥PM2.5过滤）适合雾霾城市，G4级仅挡大颗粒灰尘，选购时确认滤芯是否为通用规格便于后续更换

Unverified新风系统标准滤网组合为 G4初效 + F7中效 + H13高效，缺一层则PM2.5净化率会显著下降，纯G4+F7组合对PM2.5净化率通常低于85%，无法有效防雾霾84% similarUnverified过滤等级越高（F7/H级）净化效果越好但风阻越大、通风量衰减越明显，且滤芯更换成本更高；仅防尘防虫需求选G4即可，避免为不必要的高效滤芯牺牲通风量82% similarUnverified过滤等级越高（如H13级HEPA）过滤PM2.5越好，但风阻大幅增加导致有效风量下降和噪音上升，且滤网更换成本高；无重度雾霾地区选F7/F8(中效)+G4(初效)组合即可满足日常77% similarUnverified滤芯配置看PM2.5净化：初效滤网（防大颗粒/虫）+ H11以上HEPA（PM2.5去除率≥95%）是基本盘；重污染城市建议H13级（≥99.95%），但滤芯阻力大会降低实际新风量77% similarUnverified过滤配置应为初效（G4）+高效（H11或H13）分级过滤，H13级对PM2.5一次去除率≥99.95%，H11约95%；仅有单层滤网或标称'HEPA'但不标等级的机型净化能力存疑73% similar
