All solutions
 Home Kitchens, bedrooms, nurseries, basements. Envora shows you what you breathe — and tells you how to fix it, usually for free. Office & Co-work CO₂ is the single strongest environmental lever on office productivity — and the cheapest to fix. Envora gives facilities teams and founders the number to argue with. CO₂ and indoor air quality monitoring for schools Classroom CO₂ and indoor air quality evidence for better ventilation decisions, measurable cognitive lift, and the data trail governors and parents want. Labs & Clinics Envora One is precise enough for laboratories, clinics and regulated spaces, and comes with a signed calibration certificate per device ID. Studios & Gyms Hot yoga, spin, HIIT and small studios generate extreme humidity and CO₂ loads. Envora tells you how your ventilation is holding up — live, per-room, per-class. Podcasts & Studios Envora flags the HVAC hum, the fridge compressor, the neighbour's drill — and the concentration drift that flattens your delivery — before the tape picks any of it up. Landlords & Letting Continuous, timestamped indoor air quality records for every unit you manage — so damp disputes end in data, not arguments.

Allergies & dust sensitivity

Dust mites, pollen, pet dander and chemical irritants all have fingerprints. Envora reads them so you can manage the triggers, not just the symptoms.

What it is

The 40–50% RH sweet spot.

Indoor allergies are rarely one cause. They are a layered environment: house dust mites that thrive between 50–70% humidity, pollen that enters on clothing and draughts, pet dander that stays airborne in under-ventilated rooms, and cleaning or candle VOCs that irritate already sensitive airways.

Each has a measurable signal. Together they produce a fused, drift-compensated IAQ score that tells you when the room is friendly to you — and when it is not.

The signs

You would suspect this when any of these feel familiar.

  • Morning sneezing that eases once you leave the house
  • Asthma flare at night or on waking
  • Itchy eyes after cleaning or vacuuming
  • Worse symptoms in humid rooms or in late summer
  • Skin flare-ups in dry, heated rooms
How Envora sees it

Quietly watching the exact signals.

Humidity maps directly to dust-mite viability. Envora keeps bedrooms and living rooms in the 40–50% sweet spot — too dry for mites, too humid for static.

PM1 / PM2.5 / PM10 capture pollen loads, pet dander and the particulate tail of cleaning aerosols.

The BME690 VOC channel picks up chemical irritants — fragranced candles, bleach, sprays — that tip sensitive airways.

Watch thresholds
What to do

Practical steps, not panic.

  1. 1 Target 40–50% RH year-round in bedrooms and living rooms.
  2. 2 On high-pollen days, keep windows closed; run a HEPA purifier instead.
  3. 3 Wash bedding weekly at 60 °C and vacuum with a sealed HEPA vacuum.
  4. 4 Switch to fragrance-free cleaners; let any wet-clean dry with ventilation.
  5. 5 Keep pets out of the bedroom — or at least off the bed — and invest in allergen-resistant covers.
