Nihi Sumba at a glance
Nihi Sumba is a villa resort in Sumba Island, Indonesia. We read what it publishes about the eight things a building does to your biology and scored the evidence 6 of 24. Last verified 2026-08-17. Water Integrity is its best-documented pathway; nothing is published on Air Quality.
Each pathway scores 0 to 3 on the quality of the evidence published, not on the quality of the property. Open a row for every claim and its source.

What is not publishedthe gaps we looked for and did not find
Air Ecology, Light Rhythm and EMF Harmony have nothing published that the standard can score. Nihi Sumba confirms air conditioning in all guest accommodation and ceiling fans in villas, but publishes no filter grade, no fresh air supply rate and no carbon dioxide, volatile organic compound or particulate reading. Open flame cooking is published as a culinary method and at the Nihioka breakfast platform, and the resort states that generators run 24 hours daily; both are recorded here and neither is credited as air evidence. On light, no lighting specification, colour temperature, flicker performance, glazing detail or blackout provision is published for any villa. On EMF, no wired data topology, shielded cabling, access point or meter placement, demand switch or field measurement in a sleeping area is published; the resort's own FAQ states that satellite internet reaches every guest room by Wi-Fi and that an on site GSM tower rebroadcasts the island cell signal, and individual villa pages list Wi-Fi as an amenity, so the remoteness of the site is not a disconnection claim and has not been read as one. On water, no laboratory contaminant panel, no membrane specification and no production capacity is published for the resort's own reverse osmosis and bottling plant, and no pool or spa sanitation method or chemistry is published. On materials, no mattress composition, linen fibre content, textile certification, paint, adhesive, sealant or cleaning and laundry product is named; ikat textiles and handcrafted furnishings are described in press without fibre content, and rooms are described as sprayed daily and the property as fogged with no product or active ingredient named. On food, no share of produce grown on site, no named grower or supplier, no cooking oil policy, no cookware and no kitchen or ice water specification is published. On sound, no measured background noise level, no acoustic separation between keys and no plant or air conditioning noise figure is published. On the scent and chemical limb, the resort publishes year round ULV fogging of the property several times a week, daily spraying of rooms by housekeeping, and insect repellent as an in villa amenity. No product, active ingredient or concentration is named and no means of declining it is published. All of it is recorded as a disclosed chemical load rather than credited, on the same footing as the open flame cooking and the generators. Published floor areas and land areas for the residences are building dimensions and are not scored on any pathway. The Sumba Foundation's water wells, water stations, hand pumps, clinics, malaria programme and schools, including the widely reported daily litres figure for community supply, are the work of a separate entity serving the island population and are excluded from this record, which assesses the accommodation only. The resort publishes B Corp certification, certified June 2026 with an overall B Impact score of 80.3, held by the operating company rather than by this building. B Corp measures social and environmental performance rather than anything the eight pathways cover, so it contributes no score, and the 80.3 is not carried as a measurement on any pathway.
Other standards held
Useful context. A held standard does not move a pathway score on its own. It moves a score only through the evidence that standard publishes.

Regional context2 public figures about the area, none of which scores
Public data about the surrounding area. None of it contributes to the score, because a property cannot be marked down for the conditions outside it.
- Safely managed drinking water, Indonesia: The World Health Organization reports 30 per cent of the population nationally, 35 per cent in urban areas, 24 per cent in rural areas using a safely managed drinking water service. This describes the country, not this property, and says nothing about what reaches a guest room here. It is recorded because it is the background against which a property's own treatment is worth publishing. Source
- Ambient PM2.5 and PM10 near Sumba Island, Indonesia: Modelled ambient air over this location averaged 12.6 micrograms per cubic metre of PM2.5 and 15.9 of PM10 across the 720 hours to 2026-08-17, peaking at 43.3 PM2.5. The World Health Organization annual guideline for PM2.5 is 5. This is the outdoor air over the area, modelled rather than measured on site, and it is not a reading of the air inside any room. Source

Not published is not unsafehow to read these scores, and what this index does not promise
A low score means a property has not published information. It does not mean the property is unsafe, unhealthy or poorly run.
These scores measure disclosure. These scores describe disclosure, not property quality. This index has no commercial relationship with the properties listed unless a badge on the listing says otherwise.
Conditions change, and we will not always know. Every record is a snapshot of what a property had published when we read it, and that date is on the page. Conditions change: a property can refit, change suppliers or replace a system at any time, and nothing requires it to tell us. We re-read records and ask properties directly for updates, but there will always be a gap between what is true today and what was published when we looked. Use this as a frame of reference for what to ask, not as a substitute for asking. Take your own questions to the property before you book, and tell us if you find something we have wrong.
We report what properties publish. We do not inspect, certify or vouch for any property on this index unless a listing says we assessed it on site, and we accept no responsibility for decisions made or outcomes experienced on the basis of what you read here.
Questions travelers askwater, air, EMF, and whether it is worth it
Questions travelers ask about Nihi Sumba
Does Nihi Sumba publish water quality testing?
Yes, at specification level: a named system, supplier or standard is on the record, without a published measurement. Scored 2 of 3.
What is the air quality like in the rooms?
We can only report what is published about the rooms themselves. No. Nothing is published, and we looked. That is a statement about the public record, not about safety.
Is Nihi Sumba low-EMF?
No measurement is published. Only 14 of the 70 properties we have researched publish any bedroom EMF information at all, so this is the industry norm, not an outlier.
Is Nihi Sumba worth it?
We score evidence, not experience. On evidence, it ranks 62 of 70 researched records. The strongest documented pathways are Water Integrity and Biophilic and Healing Design; nothing is published on Air Quality or Light Rhythm.
