Verdict

The CONOPU DH-JH01 is a compact, 1.59 kg portable air purifier rated for rooms up to 20 square metres. It features a 22W energy-efficient motor and a 3-layer filtration system consisting of a pre-filter, an H13 True HEPA filter, and activated carbon, capturing 99.97% of airborne particles down to 0.3 microns. Main pros include its built-in aromatherapy slot for essential oils, user-friendly 6/12/24-hour timer settings, and ultra-quiet operation in sleep mode. However, some cons include the lack of smart app connectivity, the fact that running it on higher fan settings can be notably loud, and that replacement filters can occasionally be difficult to source.
