Best Air Purifiers for Allergies Are on Sale: Levoit, BlueAir (2026)
Save on WIRED-tested picks from Blueair, Levoit, and Air Doctor, including compact models for your bedroom.
As temperatures drop in winter, it becomes crucial to maintain a healthy indoor environment, particularly in bedrooms. Closed windows and outdated heating systems can trap stale air, allowing allergens such as pet dander and dust mites to circulate. Additionally, heating devices like fireplaces, furnaces, and heaters generate soot, dust, and other harmful odors.
While investing in a large, expensive whole-house air purifier may not be feasible for everyone, smaller portable units can be highly beneficial for individual health.
These currently discounted, WIRED-tested air purifiers can significantly improve air quality throughout the winter months. They all feature HEPA filtration, which effectively captures microscopic airborne particles such as viruses, bacteria, and respiratory droplets that heighten the risk of illness, especially as people spend more time indoors during colder months. Continuous filtering and circulation of the air also alleviate asthma triggers, congestion, and allergy flare-ups that intensify as temperatures decline.
The Blueair small-room model is a versatile option that can effectively purify air in bedrooms up to 175 square feet. Standing less than 2 feet tall, it doubles as a heater and cooling fan, making it suitable for use year-round. Available on Amazon for 55% off and $150 off at Shop with signed-in checkout, this air purifier guarantees a clean, allergen-free environment.
It achieves air exchange rates of 4.8 times per hour in a 219-square-foot space, making it ideal for rooms as small as 15×14 feet. For pet owners, an additional $35 investment grants pet-specific filters that remove larger pet hair and fur, three-stage filtration, and enhanced activated carbon to eliminate pet odors effectively.
Another highly recommended dual-purpose air purifier is perfect for bedrooms, capable of cleaning the air in a 140-square-foot room in just 13 minutes, achieving 4.8 air exchanges per hour. It also functions as a sunrise alarm clock, gradually waking users with a soothing light. Adjustable nightlight and clock functionalities enhance convenience. This all-in-one purifier is an excellent solution for those with limited space or interested in combining better air quality with a sunrise alarm clock.
