Delonghi AC100 Air Purifier with HEPA and Active Carbon Filter

Our review

The Delonghi AC100 is a compact air purifier built around a HEPA and active carbon filter, with three fan speeds and a dirty filter indicator that tells you when the filter needs attention. Its ionizer is designed to neutralize dust, pollen and smoke particles, which makes it a reasonable pick for a bedroom, small living room or office where allergies or smoke are a concern. Before buying, think about the size of the room you want to treat and how often you are willing to replace filters, since running costs add up. Compare it with purifiers that offer more speed settings or smart controls if you want finer adjustment, and check whether replacement filters are easy to find locally. The dirty filter indicator is a genuinely useful detail that many budget models skip.
