Unverified过滤精度越高流速越慢：0.02微米超滤和反渗透能拦病毒但出水慢且易堵，0.1微米超滤流速快但挡不住病毒。市政自来水选0.1微米足够，跨境高风险水源才牺牲流速换安全90% similarUnverified过滤精度越高（0.02微米）流速越慢越易堵塞，需要更频繁反冲洗；日常营地净化清澈溪水用0.1微米中空纤维流速更快更实用，不必盲目追求最高精度84% similarUnverified水龙头净水器过滤精度越高(超滤膜)则出水流量越小，通常净水流量降至1-2L/min，明显慢于原水；追求大流量与追求高精度过滤不可兼得81% similarUnverified过滤精度越高（如0.1微米超滤）出水越纯净但流量越小、滤芯堵塞越快、更换越频繁；日常淋浴除氯除锈只需5微米级PP棉即可，无需追求超滤78% similarUnverified净水能力与流速/寿命是矛盾：孔径越小（越能滤病毒）流速越慢、越易堵塞；纳滤膜挡病毒但每分钟出水少，适合小水量应急而非大量取水77% similar
