Levoit and BlueAir air purifiers on sale with HEPA filtration and specialized features

Why air purifiers matter in winter

According to WIRED, closed windows and heating systems during winter trap airborne particles like pet dander, dust mites, and pollutants indoors. Microscopic allergens that would normally disperse outdoors instead circulate in living spaces, potentially exacerbating allergies and respiratory issues.

Heating devices such as fireplaces, furnaces, and space heaters can also release soot, dust, and odors, further degrading indoor air quality. Air purifiers with HEPA filtration are positioned as a solution to reduce these particles and improve the air people breathe during colder months.

Discounted models and key features

WIRED highlights two brands with discounted air purifiers: BlueAir and Levoit.

BlueAir’s small-room air purifier, suitable for spaces up to 175 square feet, is currently 55% off on Amazon and $150 off at Shop for users who sign in at checkout. Another BlueAir model combines air purification with heating and cooling functions, offering year-round utility.

Levoit’s air purifiers include pet-specific filters priced at $35. These filters feature an enhanced activated carbon layer to absorb pet odors and capture hair more effectively than standard filters.

One model stands out for its dual functionality: it pairs air purification with a sunrise alarm clock, complete with adjustable nightlight and clock settings. This design aims to address both air quality and sleep hygiene.

What this means
