A compact KOIOS air purifier built for bedrooms, with room to spare for living rooms, offices, dorms, and apartments. It suits anyone who wants cleaner air in a quiet space, including light sleepers and families with nurseries or kids’ rooms.
What we like
- Covers rooms up to 1300 square feet, so it works for a wide range of spaces
- H13 True HEPA filter with a pre-filter and activated carbon layer to capture fine particles, dust, pet dander, odors, and smoke
- Runs quietly, with ECO mode, sleep mode, a timer, and a child lock
- Includes a soft night light and aromatherapy option for calmer evenings
Worth knowing
- Keep it running well by cleaning the pre-filter monthly and swapping the full filter every 3 to 6 months, as the maker recommends
- Use genuine KOIOS C150 replacement filters, since the maker says off-brand filters can cut down on performance
