The ideal buyer for the Coway 250 is someone living in a medium-sized room or apartment (up to 387.5 sq ft) who prioritizes ultra-fine particle removal and VOC reduction. If you suffer from severe allergies or chemical sensitivities and want superior filtration down to 0.01 microns, plus 99% VOC reduction, this is for you. The washable pre-filter appeals to those looking to reduce some recurring costs. It's perfect for a bedroom or office where specific air purification quality is more critical than rapid, expansive coverage.

The PuroAir 240 is best suited for individuals with large open-plan living spaces or multiple rooms needing coverage, up to 1,000 sq ft. If you prioritize rapid and effective air purification, especially for smoke, dust, and general allergens, its high CADR of 640 makes it highly effective. Budget-conscious buyers needing broad coverage will appreciate the value of the 2-pack. It's perfect for quickly improving air quality in homes where speed and wide area coverage are paramount, such as in homes with pets or in wildfire-prone regions.
