Unverified标准冷泡比例约为咖啡粉：水=1:8至1:10，1L瓶配约100-125g中粗研磨咖啡粉，选购时确认瓶身或滤网容量能容纳对应粉量而不溢出78% similarUnverified过滤主要针对饭粒/茶叶等细碎残渣时，网眼孔径应≤1.5mm；仅拦截大块菜叶果皮时2-3mm孔径即可，孔径过细易导致水流变慢和堵塞71% similarUnverified过滤精度越高（孔径越小）流量越低：0.1微米中空纤维壶重力式流量约0.5-1L/分钟，而0.02微米超滤或反渗透需挤压/泵压，直饮时口感偏费力，精度与便捷性此消彼长68% similarUnverified过滤精度越高（孔径越小）吸水阻力越大、流量越低，长时间吸饮易疲劳；追求顺畅口感选中空纤维0.1微米款，追求防寄生虫极致选0.02微米但需接受费力吸吮68% similarUnverified过滤精度选40微米最通用，过高（如5微米）会明显降低流量和水压，且需频繁反冲洗；低于100微米则拦不住细小泥沙。40微米可拦截泥沙铁锈等肉眼可见杂质67% similar
