cleanz.one grids the inhabited Earth into 25 km cells and measures each one against four habitability axes — water hardness, PM2.5 air quality, 5G tower density, and ADS-B flight overpass frequency. Every cell sourced, ranked, and clickable on a live interactive map. Used by environmental engineers, real-estate scouts, relocation specialists, and individuals planning a move.
Every land cell graded on the four things that quietly shape day-to-day life. We do the measurement; you find your fit.
Soft, medium, or hard — see it before you commit.
Hard water means scale, dry skin, plumbing maintenance, a lifetime of small inconveniences. Soft means easier living. Every cell graded against the same measured baseline so you don't move and find out the hard way.
A month of measurements averaged into one trustworthy number.
Brochures lie about pollution. Single-day readings fluctuate. We use a rolling 30-day mean of fine-particle concentration, banded against WHO 2021 thresholds, so "good" means good across a whole month — not just one clean Tuesday.
Choose your level of signal saturation.
Whether high-frequency exposure matters to you, or you just want the calmer signal environment of unplugged country — we mark every cell where 5G transmitters have been observed. The empty cells are still empty. You can find them.
Real overflight count, not a tourism claim.
We track every aircraft pass over every cell for thirty days. Cells that stay empty are the genuinely quiet ones — Nordic fells, Spanish meseta, Finnish lakeland. Connected-component analysis pulls out the largest contiguous quiet zones for you.
Live extract from today's EU dataset. Sorted by the percent of land in each country that's clean of both 5G and overhead flights. Mainland and islands kept apart — different lives.
| Country | Land cells | Clean | Clean % | Med Hardness | Med PM2.5 |
|---|---|---|---|---|---|
| Iceland (island) | 311 | 307 | 99% | 15 mg/L | — |
| Finland | 988 | 780 | 79% | 11 | 1.86 |
| Turkey | 1303 | 883 | 68% | 253 | 9.51 |
| Sweden | 1251 | 806 | 64% | 14 | 2.11 |
| Norway | 969 | 486 | 50% | 11 | 2.45 |
| Latvia | 151 | 69 | 46% | 194 | 3.40 |

Five things you'll do — fast for the scanner, deep for the digger.
If you're considering uprooting your life, you want the homework done before you sign a lease. The platform gives you a short-list grounded in measurements, not estate agents' adjectives.
If your client wants soft water, clean air, and a quiet sky over their next house, you can prove a candidate region works before the flight there — and quietly rule out the ones that don't.
Environmental health, water utility planning, EMF studies, relocation policy — the per-cell numbers come from public primary sources. Pull what you need; cite what you used.
Whether that's no flights overhead, no 5G in the next field, or both — you can find the cells where the noise simply isn't there, and have the data to back the choice.
The maps tell you what the measurements show. Where measurements don't exist for an area, we mark cells as no-data rather than guess. Where we use a regional-geology fallback (e.g. for Iceland or Turkey, where direct readings are sparse), the cell carries a synth tag so you can filter it out for academic work.
We don't claim "no-flights" cells are silent forever, or that "no-5G" cells are EMF-free in any absolute sense. We claim what the source data shows. Full methodology, source links, and per-cell provenance live inside your account.
Every metric is sourced from a public, citable dataset: OpenSky Network (ADS-B), OpenCelliD (5G NR towers), Open-Meteo CAMS European reanalysis (PM2.5), Spanish SINAC + Copernicus / Weber 2021 ESSD (water hardness). Each cell on the map carries a source attribution.
No. We report what the source data shows. A "no flights" cell means OpenSky received zero ADS-B transponder signals in that 25 km square over the sampling window. A "no 5G" cell means OpenCelliD has no NR transmitter on file. Real-world conditions can differ — military aircraft, non-public towers, indoor measurements all sit outside our sources.
Flight positions accumulate hourly; the 30-day window scrolls forward continuously. Water hardness and air-quality datasets are re-aggregated weekly. 5G tower data refreshed monthly from OpenCelliD bulk dumps.
One flat annual fee gets you full access — interactive EU map, world no-flight map, all rankings tables, per-cell CSV export, source attributions, and ongoing data refreshes throughout the year. No tiers, no upsells, no per-month surprise.
Yes. Disable auto-renew from your account at any time and access continues to the end of your paid year. 7-day money-back applies on first payment.
No. cleanz.one is a research instrument, not a recommendation engine. Use it as a prefilter before due diligence. We make no claim about quality of life, real-estate value, climate suitability, or any other downstream factor.
The world no-flight scan covers all inhabited landmasses globally at 1° resolution. Full multi-metric (hardness + air + 5G + flights) coverage outside the EU requires region-specific data sources — those are added by request.
