A healthier home is a measurable one.
Kitchens, bedrooms, nurseries, basements. Envora shows you what you breathe — and tells you how to fix it, usually for free.
Most home air problems cost nothing to fix. The expensive part is not knowing.
Five rooms. One quiet instrument.
We spend 90% of our lives indoors and most of that time is at home. The places where we sleep, cook, relax, and raise children are the rooms where air quality matters most — and the rooms that are monitored the least.
Envora One is designed to live on a kitchen shelf, a bedside table, or a nursery dresser. One device shows you CO₂ building up overnight, PM2.5 from a stir-fry, damp creeping into a bathroom, and the fused IAQ score that ties it all together.
Most of the fixes cost nothing. Open a trickle vent. Run the extractor longer. Move the plug-in air freshener. But you cannot fix what you cannot see — and indoor air is the thing you cannot see.
Five places your home is failing, quietly.
The invisible kitchen plume
Frying on a gas hob can push PM2.5 past urban roadside levels within six minutes. Most kitchens were built without the extraction they need, and recirculating hoods rarely touch fine particulates.
The morning-after bedroom
CO₂ doubles or triples overnight in a closed bedroom with the door shut. Most people wake fuzzy and blame their phone, their coffee or their age.
The damp that is not yet mould
Bathrooms, cellars and nurseries cross the humidity threshold silently for months before mould appears. The damage is done in the months before you smell it.
The nursery no one talks about
Nursery CO₂ is often the worst in the house — small, sealed rooms with a sleeping infant. The data parents see for the first time usually changes their nursery routine within a week.
The winter dry spike
Central heating drops indoor humidity below 25% in a matter of days. Sore throats, dry skin, cracked furniture — all preventable with a bedside humidifier once you can see the number.
The four channels that earn their keep at home.
Your air, hour by hour.
-
06:30 Sunrise
Light sensor registers the day. Envora app nudges the heating schedule.
-
07:30 Breakfast
PM2.5 spikes on the hob. Extractor on — the number comes down in minutes.
-
11:00 Working from home
CO₂ climbs in the home office. The dashboard suggests cracking the window.
-
18:30 Family dinner
Kitchen and dining room both trend up. Envora averages across the open plan.
-
22:00 Bedtime
Bedroom starts at 500 ppm. You set a trickle vent target, not a 2 AM surprise.
-
03:00 Overnight baseline
CO₂ stays under 900 ppm. Deep sleep data syncs with your wearable.
Five household nudges a week, on average.
- Bedroom CO₂ above 1,000 ppm through the night
- Kitchen PM2.5 above 35 µg/m³ for more than 5 minutes
- Bathroom humidity above 65% for more than 20 minutes post-shower
- Winter humidity below 30% across living spaces
- Any CO reading above 2 ppm, anywhere in the home

What home air quietly does to a family.
Mould & damp risk
Mould does not appear from nowhere. It is the visible end of months of sustained humidity your house has been trying to tell you about.
Read the guideAllergies & 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.
Read the guideLong-term toxic gas exposure
A CO alarm chirps at 35 ppm. Your nervous system reacts at 1. Envora watches the band that does not set anything off — but accumulates anyway.
Read the guideCooking pollution
Frying on a gas hob can push PM2.5 past a London roadside reading in six minutes. Most domestic extractors were never designed for it.
Read the guideSleep & bedroom air
The most important seven hours of your day happen in the room you measure the least. CO₂ triples overnight; humidity plummets; light and sound shape every sleep cycle.
Read the guideWinter dry air
Winter heating in the UK regularly drops indoor humidity below 25%. Sore throats, cracked furniture, increased infection risk — all avoidable once you can see the number.
Read the guideOutdoor air events
Wildfire smoke, urban traffic peaks, garden bonfires. The wrong ventilation strategy turns a bad outdoor hour into a bad indoor week.
Read the guideWe could feel our daughter's nursery was off but could not name it. Envora showed us 1,200 ppm CO₂ at 3 AM. One trickle vent later, it is 650 every morning — and she sleeps through.
