Question: what is the difference between h13 and h14 hepa filters?
Answer: HEPA H14: pass up 0.005% of 0.1 micron particles per liter of air. HEPA H13: pass up 0.05% of 0.1 micron particles per liter of air. ... HEPA H10: pass more than 15% of 0.1 micron particles per liter of air. Thus, a more optimal filtration will need a more efficient model ( H14 or H13).
