Make the invisible visible.
Radon, fine particulate matter, volatile organic compounds… Most of what shapes the air in your home is invisible to the eye. Clervo continuously measures these hidden factors and translates them into clarity.
A healthy indoor space starts with measurement.
The name "Clervo" is derived from clairvoyant — the ability to perceive what cannot normally be seen.
Modern energy-efficient buildings are increasingly airtight. While this reduces heating costs, it also allows particulates, volatile compounds, and naturally occurring gases like radon to accumulate indoors.
Clervo continuously measures these invisible factors, translates them into simple indicators, and — when needed — automatically triggers your BSK ventilation system.
The things you can't see.
Four groups of invisible factors silently shape the air you breathe at home.
Radon
A radioactive gas that seeps from soil and is a leading cause of lung cancer among non-smokers.
PM1 · PM2.5 · PM10
Microscopic particles from dust, traffic, and cooking that penetrate deep into the respiratory system.
VOC
Volatile compounds emitted by cleaning products, furniture, paints, and adhesives over time.
CO₂ & CO
The clearest signal of ventilation efficiency — and a silent marker of combustion-related risk.
Two devices, one ecosystem.
Clervo Radon and Clervo IAQ are two complementary smart sensors that monitor your home's air end to end. Manage everything from a single screen with the BSK Connect app.
Radon & Climate Monitor
Continuous protection for radon, temperature, and humidity.
- Radon measurement range: 2 Bq/m³ – 20 kBq/m³
- ±0.1°C temperature · ±1.8% RH humidity accuracy
- Mold Analyzer for structural risk warnings
- Compatible with Google Home & Home Assistant
Comprehensive Air Monitor
Real-time indoor analysis across 7 parameters.
- PM1 / PM2.5 / PM10, VOC, CO₂, CO, temperature, humidity
- 0–180 IAQ Index for intuitive health insights
- Viral Risk, Allergy, Sleep & Baby-Elder analyzers
- Automated ventilation with BSK Notus & Zephyr
Protection for those who matter most.
Clervo is designed for the spaces where you spend the most time — bedrooms, living rooms, children's rooms. Extra care for those most sensitive to indoor air quality.
A protected start for two
Elevated radon levels can quietly accumulate in indoor spaces. Continuous monitoring helps detect risk early — supporting a safer environment for mother and baby.
Deeper, more restorative rest
High CO₂ and imbalanced humidity disrupt deep sleep cycles. Clervo IAQ monitors bedroom conditions and can automatically trigger ventilation to restore fresh air.
See what cleaning leaves behind
Cooking, cleaning, and new furniture release VOCs you can't smell. Clervo IAQ surfaces these sources — so you can ventilate before they accumulate.
Not a single reading, a complete picture.
Clervo IAQ never reduces indoor air to a single number. It measures multiple indicators simultaneously to map your air quality in full.
Particulate Matter
Tracks dust, pollen, and ultrafine combustion particles across three size ranges — the particles that affect respiratory health most directly.
Volatile Compounds
Detects organic pollutants released by paints, furniture, and cleaning products, and alerts you before they reach harmful levels.
Carbon Dioxide
The clearest signal of ventilation efficiency. High levels impair concentration, cognitive performance, and sleep quality.
Carbon Monoxide
Colorless, odorless, silent. Prevents poisoning risk from boilers, fireplaces, and fuel-burning appliances before symptoms appear.
Radon
A radioactive gas that rises from the soil. The WHO links long-term exposure above 100 Bq/m³ to elevated lung cancer risk.
Temperature & Humidity
20–24°C and 40–60% RH form the optimal comfort range — the zone that minimizes mold, bacteria, and viral spread.
Read the air at a glance.
Clervo's integrated LED ring tells you the state of your indoor air without ever touching your phone. A calm, refined color language — fully customizable, dimmable, or entirely off.
Customize the lighting behavior through the mobile app: switch between neutral white calm mode and explicit color mode to match every interior.
