对 Wirecutter 宜家空气净化器评测的反驳
Contra Wirecutter on the IKEA air purifier

导读
这篇文章逐条反驳 Wirecutter 对 IKEA 空气净化器的评测，重点围绕 HEPA 标准、过滤效率、CADR 与测试方法。它认为 Wirecutter 的筛选标准可能把“够用且便宜”的选项排除在外，并质疑其评测逻辑；评论区则有人指出原文对 Wirecutter 的若干说法也有误。
为什么经久不衰：它把一个看似简单的“买哪台净化器”问题拆成评测标准、利益冲突和可盲买推荐之间的取舍，是理解消费评测局限的经典案例。

专业消费品评测稀缺，Wirecutter 虽有缺陷仍是少数可信来源。
Wirecutter 是一个很有缺陷的评测网站，但至少它是真实的。面向普通消费品剩下的这类网站少得可怜。除了 WC、Consumer Reports 还有谁？它们似乎都被消灭了。当我研究某类产品时，如果能找到由真正摸过产品的人写的专业评测，我就觉得很幸运。我们都知道那种经历：谷歌“X 的评测”，结果被 SEO 垃圾淹没。更别提找到有使用经验的人写的东西，能找到人写的就不错了。

The Wirecutter is a highly flawed review site, but at least it's a real one. There are vanishingly few left for general consumer products. There's WC, Consumer Reports, and what else? They've seem to have all been killed off. When I'm researching some category of product, I feel lucky if I find any professional reviews written by people who have actually touched the thing they're reviewing. I know we've all had the experience googling "reviews of X" only to get overwhelmed with SEO spam. Forget finding something written by somebody who has experience with it. It's hard enough to find something written by a human.
反驳原文，指出 Wirecutter 的 HEPA 标准与 CADR 理由被误读。
这篇文章本身就有不少错误。比如它称 Wirecutter 认为空气滤网像筛子，但 Wirecutter 的空气净化器评测页恰恰解释了并非如此，还引用 NASA 研究说明 HEPA 对小于和大于 0.3 微米测试标准的颗粒都有很好捕获能力。Wirecutter 用 HEPA 标准筛选众多净化器；IKEA 滤网因不符合 HEPA 标准被排除（文章纠结 true-HEPA 营销词是误导，因为作者自己引用的 wiki 显示 E12 不算 HEPA）。不过 Wirecutter 也联系了 IKEA，IKEA 发言人表示他们关注 PM2.5。他们不推荐 IKEA 不是因为它不能捕获更细颗粒，而是因为捕获细颗粒效率不如 HEPA，且 CADR 更低。它不符合他们设定的标准，所以不纳入价格比较。也许标准不对，也许应允许更低 CADR 或低于 HEPA 的滤网。但文章暗示他们不懂自己在说什么，完全错了。

This article actually makes a bunch of claims itself that are false. For example, it claims that the Wirecutter believes air filters work like sieves. Whereas the Wirecutter review page for air purifiers goes into how they do not behave like sieves and also references a NASA study that shows how HEPA filters are good at capturing both particles smaller and larger than the 0.3 micron test standard. It’s pretty obvious that the Wirecutter has used HEPA standard filters as a filter for whittling down the many air purifiers that exist in the world. They eliminated the IKEA filters because they do not meet HEPA standards (this blog’s focus on he true-HEPA marketing term is misguided, because the authors own referenced wiki link shows that E12 is not considered HEPA). However, they also reached out to IKEA about this, and the IKEA spokesperson told them their focus is on PM2.5. They don’t recommend the IKEA filter based not on its inability to capturer finer particles, but because it’s not AS efficient as capturing finer particles as HEPA filters, AND because of its lower CADR. It doesn’t meet the standards they set, so they don’t include it for price comparisons. Maybe they haven’t set the right standards. Maybe they should have allowed for lower CADRs or for filters that meet lower filtration standards than HEPA. However, the insinuation this article makes that they don’t seem to understand what they’re talking about is completely wrong. Maybe this author should try reviewing over 20-30+ different air purifiers at a minimum without setting arbitrary thresholds up front and then get back to the Wirecutter folks.
Wirecutter 的价值在于规模化地给出低风险可盲买的推荐，覆盖家电是稀缺能力。
Wirecutter 就像 Leetcode 面试。目标不是找到“最好”选项，而是在巨大时间压力下最小化假阳性。他们的推荐通常是 8/10 的稳妥选项，可以闭眼买且大体满意。过程中会淘汰或误述其他可比选项，但最终推荐从不差。这与 IGN 给每款新摇钱树游戏 10/10、The Verge 迎合主流求稳形成鲜明对比。此外 Wirecutter 指南更新及时、覆盖几乎所有类别。rtings、Anandtech、LTT、Crinacle、notebookcheck、gsmarena 等更好吗？是的，100%。但它们各自覆盖小 niche，尤其不覆盖各类家电。我同意 Dynomight 说 Wirecutter 平庸。但一致的平庸在大规模执行上极其困难。除非绝对必要，我不会用 Wirecutter。但经常我绝对必要，因为没有其他足够可信的人评测加湿器和吸尘器。

Wirecutter is like Leetcode interviews. The goal is not to find the 'best' option, but minimize false positives under intense time-pressure. Their recommendation is usually the 8/10 solid option that you can blindly buy and be moderately satisfied with. In the process, they drop out or misrepresent other comparable options, but their final recommendation is never shoddy. This is in stark contrast to other reviewers like IGN who give 10/10 to every new cash-cow game, and The-Verge that tows the 'mainstream' line to play it safe. Additionally, Wirecutter's guides are up-to-date and cover every imaginable category. Are rtings, Anandtech, LTT, Crinacle, notebookcheck, gsmarena, etc. better ? Yes, a 100%. But each of them cover a small niche and particularly leave out appliances of all types. I agree with Dynomight on Wirecutter being mediocre. But, consistent mediocrity is incredibly hard to execute at at scale. I would never use wirecutter unless I absolutely had to. But, often, I absolutely have to. Because no one else remotely trustable is going around reviewing humidifiers and vacuum cleaners.
暗示推荐名单可能受佣金利益影响。
不想当阴谋论者，但他们在文章里唯独点名不推荐购买的 IKEA 款，是唯一一件别人购买时他们拿不到佣金的。

Not to be a conspiracy theorist, but the IKEA one which they singled out as not recommended to buy is the only one in the article they don't earn a commission on when someone buys it
