PM2.5 Filter Guide UK - How CR Box Removes Fine Particulate Matter
PM2.5 fine particulate matter is one of the most dangerous air pollutants, penetrating deep into lungs and bloodstream. The CR Box with HEPA H13 filtration captures 99.95% of PM2.5 particles, protecting your family from harmful pollution. London averages 10-15 µg/m³ PM2.5 - above WHO guidelines.
