Best Air Purifiers for Allergies Are on Sale: Levoit, BlueAir (2026)

You may be searching for the best air purifiers for allergies, pets, mold, wildfire smoke, or exhaust—such as from cars or industrial buildings—to protect yourself and your home from potentially harmful air pollutants, especially as the seasons change.

您可能正在寻找最适合应对过敏、宠物、霉菌、山火烟雾或汽车及工业建筑废气的空气净化器，以便在季节更替之际保护您自己和您的家免受潜在有害空气污染物的侵害。

As winter creeps in and the outside air gets colder, having a good air purifier for your living space (especially your bedroom) is essential to reducing airborne particles. Closed windows and older heating systems often trap stale air and indoor pollutants, and microscopic allergens like pet dander and dust mites circulate your home instead of wafting outside. Plus, heating devices like fireplaces, furnaces, and heaters can create soot, dust, and other potentially harmful odors.

随着冬季悄然来临，室外空气变得寒冷，为您的生活空间（尤其是卧室）配备一台优质的空气净化器对于减少空气中的颗粒物至关重要。紧闭的窗户和老旧的供暖系统往往会将浑浊的空气和室内污染物困在室内，而宠物皮屑和尘螨等微小过敏原也会在您的家中循环，而无法散发到室外。此外，壁炉、熔炉和加热器等供暖设备可能会产生烟灰、灰尘以及其他潜在的有害气味。

If you don’t want to break the bank on a large, expensive whole-house air purifier, a smaller, more portable one can still be extremely beneficial to your health. You can move it around your house and keep it in your bedroom to help keep the air healthy and germs at bay as you sleep.

如果您不想花费巨资购买大型且昂贵的全屋空气净化器，那么小型、便携式的设备对您的健康依然大有裨益。您可以将其在家中随处移动，并放在卧室里，以帮助您在睡眠时保持空气健康并抵御病菌。

These on-sale, WIRED-tested air purifiers below can help make your home healthier this winter for less. All of these picks have HEPA filtration options, which capture microscopic airborne viruses, bacteria, and respiratory droplets that increase the likelihood of illness, especially when people spend more time indoors together during the colder months. Keeping the air continually filtered and circulating also helps ease asthma triggers, congestion, and allergy flare-ups that often get worse as the temperature drops.

以下这些正在打折且经过《连线》（WIRED）测试的空气净化器，能以更低的价格帮助您在今年冬天打造更健康的家居环境。所有这些精选产品均具备 HEPA 过滤选项，能够捕获空气中微小的病毒、细菌和呼吸道飞沫，这些物质会增加患病几率，尤其是在寒冷月份人们更多时间聚集在室内的情况下。保持空气持续过滤和循环也有助于缓解哮喘诱因、鼻塞和过敏症状，这些问题往往会随着气温下降而加重。

A Bedroom Air Purifier for Pet Allergies: Levoit Core 300-P Air Purifier ($100 $85). I first bought this little air purifier when I was moving into my small Brooklyn apartment with two cats and a roommate who has allergies.

You can opt for the pet-specific filters for $35, which include a nylon pre-filter mesh to catch larger pet hair and fur before it reaches the deeper internal HEPA filter.
