In-room air purifier
A true-HEPA purifier in the room or on request, with no ozone-generating or ionizing function.
Why it matters
Portable HEPA units lower indoor particle levels, which matters most during wildfire smoke. Ionizers and ozone purifiers can add an irritant gas instead.

Santa Monica Proper Hotel
Not yet reviewed.
So far, the hotel says: The Wellness Rooms and the Proper Sleep Room have ‘purifier-equipped air’ and ‘premium air filtration’.
Our note. Whether the units are true HEPA, and whether any emits ozone, is not stated, so this falls short of the criterion. Standard rooms are not described.

Viceroy Santa Monica
Not yet reviewed.
So far, the hotel says: Every room has ‘an air purifier or HEPA filter’.
Our note. Whether each unit is true HEPA, and whether any emits ozone, is not stated, so this falls short of the criterion.
