BSK CLERVO · INDOOR AIR QUALITY

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.

Philosophy

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.

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.

Elevated radon levels can quietly accumulate in indoor spaces. Continuous monitoring helps detect risk early — supporting a safer environment for mother and baby.

Sleep Quality

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.

Daily Activities

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.

Measured Parameters

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.

PM1 · PM2.5 · PM10

Particulate Matter

Tracks dust, pollen, and ultrafine combustion particles across three size ranges — the particles that affect respiratory health most directly.

VOC

Volatile Compounds

Detects organic pollutants released by paints, furniture, and cleaning products, and alerts you before they reach harmful levels.

CO₂

Carbon Dioxide

The clearest signal of ventilation efficiency. High levels impair concentration, cognitive performance, and sleep quality.

CO

Carbon Monoxide

Colorless, odorless, silent. Prevents poisoning risk from boilers, fireplaces, and fuel-burning appliances before symptoms appear.

Rn

Radon

A radioactive gas that rises from the soil. The WHO links long-term exposure above 100 Bq/m³ to elevated lung cancer risk.

T · RH

Temperature & Humidity

20–24°C and 40–60% RH form the optimal comfort range — the zone that minimizes mold, bacteria, and viral spread.

Intelligent Light Feedback

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.

Answers to the most common questions about Clervo.

What's the difference between Clervo Radon and Clervo IAQ?
Clervo Radon focuses specifically on radon gas, temperature, and humidity, with mold risk analysis. It's ideal for homes with basements or ground-floor living spaces.

Clervo IAQ measures 7 parameters including particulate matter, VOC, CO₂, CO, temperature, and humidity, with sleep, allergy, and viral risk analyzers. Designed for comprehensive indoor health. Using both devices together creates a complete ecosystem.
Is setup complicated? Do I need a technician?
Not at all. Clervo devices are designed for true plug-and-play use. Connect the Type-C cable to a power outlet, download the BSK Connect app, and follow the automatic pairing — setup takes less than 2 minutes.
Which ventilation systems does it work with?
Clervo is fully integrated with BSK Notus and BSK Zephyr ventilation systems. It is also compatible with the Google Home and Home Assistant ecosystems, so it fits naturally into your existing smart home automation setup.
Is the LED ring distracting? Can I turn it off?
Yes, it's fully under your control. You can dim the LED ring, schedule automatic dimming at night, or turn it off entirely. There's also a "Calm Mode" that uses a single soft white light — ideal for bedrooms.
Is my data secure? Who has access to it?
All measurement data is stored encrypted and only accessible through your personal BSK Connect account. You can export your data at any time or delete your account to remove all records.
