Filtration Technology
The YIOU uses a 3-stage filtration system starting with a pre-filter that traps larger particles like pet hair and dust, followed by an H13 True HEPA filter rated to capture 99.97% of particles at 0.3 microns, and finished with an activated carbon layer that absorbs VOCs, smoke, and household odors. The H13 grade is a step above standard HEPA and matches the filtration level found in many purifiers costing significantly more.
This combination effectively handles allergens, fine dust, pollen, and common household pollutants.
Noise & Performance
At its lowest setting, the YIOU produces just 20 dB of noise , quieter than a whisper and among the quietest third of all air purifiers on the market. 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, delivering approximately 2 air changes per hour at maximum room size.
For bedroom use or a home office, the sleep mode keeps noise and light output minimal while maintaining airflow.
Smart Features & Controls
Controls are manual with touch buttons on the unit itself , straightforward but basic compared to app-enabled competitors. The built-in air quality indicator provides real-time feedback on pollution levels, and sleep mode dims the display while reducing fan noise for nighttime operation.
There is no WiFi connectivity, no smartphone app, and no voice assistant compatibility, so everything must be adjusted directly on the purifier.
Filter Maintenance
The replacement filter (model B0972641SV) is designed for straightforward swaps, and the built-in filter change indicator takes the guesswork out of replacement timing. The pre-filter layer captures larger particles first, which helps extend the life of the main HEPA filter.
Typical replacement intervals depend on usage and air quality, but the indicator light will alert you when it is time to install a fresh filter.
