MERV（Minimum Efficiency Reporting Value）是一个用来描述空气过滤器过滤效率的标准。 该标准将空气过滤器的过滤效率划分为12个等级，从MERV 1到MERV 20。 每个MERV等级都对应着一组颗粒物的过滤效率，下面是各个MERV等级的对应关系： MERV 17-20：能捕捉更小的颗粒物，如烟雾、病毒和细菌等，过滤效率为99.99%-99.999%。 需要注意的是，每个MERV等级对应的过滤效率都是在特定测试条件下得出的结果，实际的过滤效果可能受到多种因素的影响，如空 …

2019年1月4日 · MERV 中文為「最小過濾效率值」，是 ANSI/ASHRAE 標準中所提出的濾網過濾效率等級，依照過濾效率的不同分為 16 個等級，雖然已經有 17~20 級的定義，但目前還沒被列入標準測試分級中。

In the most basic sense, the MERV rating gives us an idea of how well filters (air purifiers, furnaces) can filter out 0.3 to 10 micron (10 -6 m) particles. That’s the size interval that includes most air pollutants smoke, dust, cooking oil smell, mold spores, and bacteria, to name just a few.

Depending on their design, air filters (bag filters or cartridges) have different degrees of efficiency towards dust particles. This page aims at detailing the different norms for filter efficiency (MERV, ISO) and to help the reader chose the right filter specification depending on the …

MERV, or Minimum Efficiency Reporting Value, is a rating system that measures the effectiveness of air filters in capturing particles from the air. In this comprehensive guide, we'll delve into the question “What is a MERV rating?”, how to choose the right rating for your home, and how to maintain optimal air quality with MERV filters.

2024年10月7日 · MERV stands for Minimum Efficiency Reporting Value. MERV ratings range from 1–20. The higher the MERV rating on a filter, the fewer dust particles and other …

2023年12月11日 · HEPA過濾器使用的評級系統稱為最小效能報告值（MERV），評級範圍從1到20。 MERV評級越高，過濾器在捕捉較小顆粒方面的效能越高。 HEPA過濾器通常具有MERV評級為17到20（詳細如下），這意味著它們可以以99.97%的效能捕捉到0.3微米大小的顆粒。

Minimum Efficiency Reporting Value, commonly known as MERV, is a measurement scale designed in 1987 by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) to report the effectiveness of air filters in more detail than other ratings.

2021年10月15日 · The MERV value represents the particle capture efficiency of a filter at specific size ranges. The higher a filter’s MERV value, the better that filter is at capturing smaller particles.
