Filtration Technology
The YIOU uses a 3-stage filtration system starting with a pre-filter that catches larger particles like pet hair and dust, followed by an H13 True HEPA filter that captures 99.97% of airborne particles as small as 0.3 microns, and an activated carbon filter layer that absorbs odors, smoke, and VOCs. The H13 grade HEPA is the same medical-grade standard used in hospital environments, placing this purifier above many entry-level competitors that use lower-grade HEPA or HEPA-type filters that don't meet true H13 certification.
Noise & Performance
At its lowest setting, the YIOU operates at just 20 dB , quieter than a whisper and virtually inaudible in a bedroom setting. CADR ratings of 139 CFM for dust, 140 CFM for smoke, and 144 CFM for pollen are solid for its 547 sq ft coverage area, though the 2 air changes per hour means it cycles air less frequently than some competitors in this category.
For bedrooms and home offices, the noise-to-performance balance is excellent; for larger open-plan spaces, you may want to size up.
Smart Features & Controls
Controls are manual with physical buttons for fan speed adjustment, a dedicated sleep mode, and an air quality indicator that gives you visual feedback on current conditions. The sleep mode reduces fan noise and dims the display lights for nighttime use.
What's notably missing is any WiFi connectivity, app control, or voice assistant integration , this is a straightforward, no-frills purifier that prioritizes filtration performance and quiet operation over smart features.
Filter Maintenance
The YIOU includes a filter change indicator that alerts you when it's time for a replacement, taking the guesswork out of maintenance. Replacement filters use model number B0972641SV and are widely available as an entry-level options , a key advantage for long-term cost of ownership.
The pre-filter layer captures larger particles first, which helps extend the life of the HEPA filter behind it.
