Most sites selling these don't mention it. Here are the numbers.\u003c\/p\u003e\n\u003cp\u003eThe X3 is certified by the California Air Resources Board and tests at roughly 0.01 parts per million (ppm) over 24 hours — a fifth of CARB's 0.05 ppm limit. If you know you're ozone-sensitive, a straight HEPA unit with no ionization is the more conservative choice. If you're not, this is well within the safety margin.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eTHE ROOM SIZE MISTAKE ALMOST EVERYONE MAKES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAirdog rates the X3 at 942 square feet — but that's one air change per hour. For asthma and allergies you want four or five.\u003c\/p\u003e\n\u003cp\u003eAirdog says so themselves: they recommend 215 sq ft for four changes per hour, 287 for three. So use 215 as your real number. It clears that space in about 15 minutes.\u003c\/p\u003e\n\u003cp\u003eA bedroom. A small office. A nursery.
