The Best Air Purifier of 2026: Tested Picks for Every Room

2026年最佳空气净化器：针对不同房间的实测精选

No matter where you live, the best air purifier for you is one that is tailored to your specific clean-air need. I lived in Los Angeles and San Francisco for almost a decade, including during some of the most severe wildfires the region has seen in recent years. Beneath an eerily yellow sky with smoky, stagnant air, I donned an N95 mask as a bartender—long before the pandemic made masking the norm. Needless to say, I’m no stranger to bad air and can appreciate the value of a good air purifier. 无论你住在哪里，最适合你的空气净化器一定是能够满足你特定空气净化需求的设备。我在洛杉矶和旧金山生活了近十年，期间经历了该地区近年来最严重的几场山火。在烟雾弥漫、空气停滞的诡异黄色天空下，我戴着N95口罩在酒吧工作——那远在疫情让戴口罩成为常态之前。不用说，我对糟糕的空气并不陌生，也深知一台好的空气净化器的价值。

Now I live in New York City, where the threat of wildfires ravaging large swaths of land is less imminent, but contaminants from cars and buses, cigarette smoke, and building and industrial emissions are ever present. Not to mention the volatile East Coast weather that’s known to host newsworthy pollen spikes, and more recently, wildfire smoke drifting down from Canada. Plus, I live in a tiny apartment with a gas stove and no hood vent (yikes!), and I also have two very furry cats and a roommate who is allergic to them. So, while my focus may be less on outside air quality, I wage a daily battle fighting pet dander and microscopic allergens in my home. 现在我住在纽约市，虽然这里山火肆虐大片土地的威胁较小，但汽车、公交车、香烟烟雾以及建筑和工业排放带来的污染物却无处不在。更不用说东海岸多变的天气，这里常有引起新闻关注的花粉激增，最近还有从加拿大飘来的山火烟雾。此外，我住在一个没有抽油烟机的小公寓里（天哪！），还养了两只毛茸茸的猫，而我的室友对它们过敏。因此，虽然我关注的重点可能不再是室外空气质量，但我每天都在与家中的宠物皮屑和微小过敏原进行斗争。

We tested each purifier throughout our real homes and in a sealed tent with smoke pellets. We measured visual smoke clearance, time to return to healthy air-quality readings, noise levels, room coverage, app performance, and filter design. The budget Coway Airmega Mighty2 ($270) is the best choice for most people, and the IQAir Atem X ($1,400) is our premium pick if you prioritize design and long-term repairability over price. I’m continuously testing new models to stay up-to-date with the best air purifier for every budget, room size, and pollutant. 我们在真实的家中以及使用烟雾弹的密封帐篷里测试了每一款净化器。我们测量了视觉上的烟雾清除效果、空气质量恢复到健康读数所需的时间、噪音水平、房间覆盖范围、应用程序性能以及滤网设计。经济实惠的 Coway Airmega Mighty2（270美元）是大多数人的最佳选择；如果你更看重设计和长期可维修性而非价格，IQAir Atem X（1400美元）则是我们的高端首选。我一直在测试新机型，以确保能为各种预算、房间大小和污染物类型提供最新的最佳空气净化器推荐。

Updated September 2026: I’ve added the Dreame Air Purifier FP10 and Coway Airmega Halo, removed some picks, and ensured up-to-date links and prices throughout. 2026年9月更新：我增加了 Dreame Air Purifier FP10 和 Coway Airmega Halo，移除了部分旧选品，并确保了文中链接和价格的实时更新。

How Do I Test Air Purifiers?

我是如何测试空气净化器的？

I have started a uniform testing method for every air purifier I test, measuring each unit’s efficacy by using a sealed tent and smoke pellets to see how quickly each air purifier clears the pellet smoke and returns the air to healthy quality when on auto mode. I measure first visually, using a timer to measure how long it takes to clear the smoke by eye. Then I measure how long it takes for the air quality to return to healthy, using both my air quality monitor and the connected app or display on the air purifier machine. I then add up the time and am able to compare models with concrete data. I also use a decibel meter on my phone to calculate noise levels during sleep and auto modes, as well as at its highest setting, since air purifiers can be egregiously loud on their most powerful setting. 我为每一台测试的空气净化器制定了统一的测试方法：通过密封帐篷和烟雾弹来测量每台设备的功效，观察其在自动模式下清除烟雾并使空气质量恢复健康的速度。首先，我通过肉眼观察并使用计时器记录清除烟雾所需的时间。接着，我利用空气质量监测仪以及净化器自带的应用程序或显示屏，测量空气质量恢复到健康水平所需的时间。然后，我将这些时间汇总，以便用具体数据对比各款机型。此外，我还使用手机上的分贝计来计算睡眠模式、自动模式以及最高档位下的噪音水平，因为空气净化器在最强档位时可能会非常吵闹。

Best Air Purifier Overall: Coway Airmega Mighty2

最佳整体空气净化器：Coway Airmega Mighty2

The Coway Airmega Mighty2 is the updated edition of our former pick for best affordable purifier, the Airmega Mighty. It’s best for most homes and a great choice for anyone who wants a quiet, compact, reliable, and relatively affordable air purifier that needs minimal intervention. You just won’t get some extras, like a connected app or remote. Coway Airmega Mighty2 是我们之前评选的最佳经济型净化器 Airmega Mighty 的升级版。它最适合大多数家庭，对于那些想要一台安静、紧凑、可靠且相对实惠，且无需过多人工干预的空气净化器的人来说，是一个绝佳选择。只是你无法获得一些附加功能，例如联网应用程序或遥控器。

This edition has an overall bigger air-purifying system, with a prefilter to catch larger particles, a carbon filter to capture odors, and a HEPA filter to trap microscopic airborne pollutants. The latter two filters are combined into one piece that only needs to be replaced once a year—double the time of a typical air purifier filter. The Mighty2 can clean the air of up to 1,800 square feet in one hour (based on one air exchange per hour), and for smaller spaces, 900 square feet in 30 minutes. 这一版本拥有整体更大的空气净化系统，配备了用于捕捉大颗粒物的预滤网、用于吸附异味的活性炭滤网，以及用于拦截空气中微小污染物的 HEPA 滤网。后两种滤网合二为一，每年只需更换一次——这比典型的空气净化器滤网寿命长了一倍。Mighty2 可以在一小时内净化高达 1800 平方英尺的空气（基于每小时换气一次），而在较小的空间内，30 分钟即可净化 900 平方英尺。
