Can you please tell me? On the comparison of the units - towards the top of the page it has a column that says “Particle Filtration Average Final .3 micron Concentration” and it shows the Honeywell HPA300 and Levoit Core 600S both with lower particle concentrations than the CR Box. With the HPA300 at 35 and the 600S at 18. Then the CR Box would be 3rd best at 38 particles/L. So, doesn’t that mean the HPA300 and 600S both did a better job of filtering .3 microns than the CR Box?

Thank you for your help.
