Air
What you breathe for eight hours a night: smoke history, fresh air, filtration and anything burning in the room.
Smoke-free property
Hotel-reportedacross the property
The hotel says: ‘Hotel Figueroa is a 100% smoke-free hotel. Smoking, including tobacco, vapes, e-cigs, and marijuana, is prohibited.’
Our note. Rooms have sensors to detect smoking, and a fee is charged if it is detected.
How we know
What we look for. No smoking in any guest room, balcony or indoor space.
Why it matters. Tobacco smoke leaves a residue (thirdhand smoke) on surfaces and in dust. A study of California hotels found that non-smoking rooms in hotels that allow smoking elsewhere did not protect non-smoking guests from it.

Filtered fresh air

In-room air purifier
Not yet reviewed.
So far, the hotel says: Molekule air purifiers ‘have been set up throughout the suite’.
Our note. The hotel does not say whether the units are true HEPA or free of any ozone or ionizing function, so this falls short of the criterion. Only the Rest & Recovery Suite is described.
How we know
What we look for. 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.

Sleep & materials
The textiles, mattress and floor you spend the night closest to, and how allergen-aware the room is.
Tested or organic bed linen
Not yet reviewed.
Mattress materials disclosed
Not yet reviewed.
So far, the hotel says: The Rest & Recovery Suite has ‘an intelligent Eight Sleep mattress that ensures your ideal sleep temperature’.
Our note. The mattress’s materials and how it meets flammability rules are not stated.
How we know
What we look for. The hotel says what its mattresses are made of and how flame-retardancy is achieved.
Why it matters. Flame retardants have been added to mattresses and seating foam, and the US National Institute of Environmental Health Sciences lists possible effects including endocrine and thyroid disruption. How much a mattress adds to anyone’s exposure is still debated; disclosure lets guests choose.

Outdoor or low-chloramine pools
Hotel-reportedacross the property
The hotel says: The pool is an outdoor, ground-level, full-sized pool, heated to 82 degrees.
Shown for information; not scored.
How we know
What we look for. Pools are outdoors, or indoor pools have dedicated ventilation and monitored combined chlorine.
Why it matters. Chloramines irritate the skin, eyes and airways, and they build up in the air of indoor pools without enough ventilation. Outdoor pools, and good ventilation for indoor ones, keep levels low.

Context, not scored: almost every pool in this catalog is outdoors, so it says little about one hotel against another.

Food
Allergen care first; where the produce comes from second.
Allergen-aware kitchen
Not yet reviewed.
Garden or organic produce
Not yet reviewed.
So far, the hotel says: The poolside menu is described as ‘filled with organic fare’.
Our note. No share of organic or home-grown produce is given, so this falls short of the criterion.
Shown for information; not scored.
How we know
What we look for. A meaningful share of the kitchen’s produce is grown on site or certified organic.
Why it matters. A large review found detectable pesticide residues about four times as often in conventional crops as in organic ones. Over a short stay the difference in exposure is small, so we show this as a note on the kitchen, not a scored health factor.

Light & quiet
Darkness and silence at night, and radio-quiet options for guests who want them.
Darkness and quiet
Not yet reviewed.
So far, the hotel says: In the Rest & Recovery Suite, ‘noise pollution is minimized with Bollsen Life+ Earplugs’.
Our note. Earplugs are not sound insulation, and blackout shades are not mentioned, so this falls short of the criterion.
How we know
What we look for. Blackout shades and sound insulation that let the room become properly dark and quiet.
Why it matters. Night-time noise fragments sleep; the WHO’s night noise guidelines set a target of 40 dB outside the bedroom. A dark, quiet room is the simplest sleep aid there is.
