A frugal small purifier for a desk, nursery or small bedroom up to about 85 sq ft.
Amazon $34.99Under $150 covers the sweet spot for single-room purifiers: true HEPA filtration, a CADR high enough for a bedroom or small living room, and often a quiet sleep mode. Many add an activated carbon layer for odors, though it is usually thin.
The real cost shows up later in replacement filters, so check the filter price and how often it needs changing. Match the rated room size to your space, and be wary of ionizers or ozone-producing features that add little. Look for a CADR figure rather than a coverage claim, and check the noise level on the speed you would actually use.
