Here's something worth knowing before you buy any air purifier.
Not all HEPA filters are the same.
The term HEPA gets used across the entire air purifier market, but there's a significant difference between filter grades that most brands don't explain. Standard HEPA 13 filters — the kind found in the majority of consumer purifiers — capture 99.97 percent of particles at 0.3 microns. That sounds impressive until you understand that some of the most harmful airborne particles are smaller than that.
HEPA 14 is the next level. Medical grade. Used in hospital environments and pharmaceutical cleanrooms. It captures 99.99 percent of particles down to 0.1 microns — and independent lab testing has shown it to be approximately ten times more effective than HEPA 13 at capturing the fine particulate matter most linked to respiratory irritation and allergy symptoms. The PuroAir 400 is one of the only consumer air purifiers built around a HEPA 14 filter. Add an activated carbon layer for odors, VOCs, and chemical gases. Add a pre-filter that extends the life of the system. Add a smart sensor that reads your air quality in real time and adjusts automatically. Put all of that in a unit rated for 2,000 square feet, verified by an independent ISO certified lab, and certified by CARB, UL, ETL, and Energy Star. That's the difference between a purifier and the PuroAir 400.
