KOIOS True HEPA Air Purifier

The H13 True HEPA Air Purifier captures 99.97% of airborne particles — dust, pollen, pet dander, smoke, and mould spores — so the air in your bedroom or office is genuinely cleaner, not just filtered. Compact enough to sit on a nightstand or desk, it runs as quietly as 22dB on sleep mode, which means it won't wake you or distract you while it works. A 3-stage filtration system pulls air in from 360°, passes it through the H13 True HEPA filter, and returns cleaner air into the room. One concern worth addressing upfront: the filters are not washable and should be replaced every 3–6 months to maintain filtration performance. Using off-brand replacement filters can reduce effectiveness, so stick with the correct filter for this unit.
