Impaired Decision Making
At ~950 ppm CO2, common in occupied rooms, cognitive function drops by 21% per 400 ppm increase. In well-ventilated spaces, strategic thinking scores were 288% higher (Harvard COGfx study).

The Problem
Ill-ventilated bedrooms are hurting your sleep & health
Harmful gasses like CO2 from exahaltion and VOCs from off gassing, climb in concentration without fresh air ventilation.
53%
of Adults, sleep with their windows closed
One standard sized room with just 2 people can reach CO2 levels of 2000-3000ppm overnight, exceeding the 880ppm threshold.
90%
of an individual's day is spent staying indoors
Without proper ventilation indoor spaces can get up to 2-5x more polluted than outdoors by trapping CO2 and harmful Volatile Organic Compounds (VOC's).
Leading to
Headaches & Fatigue
Stale air and built-up VOCs drive headaches, dizziness, drowsiness, and afternoon slumps. Sick Building Syndrome affects an estimated 57% of offices.
Allergy & Hay Fever Flare-ups
Poor airflow and humidity let dust mites and mould thrive in bedding and carpets, triggering allergies, sinus issues, and asthma. Over half of U.S. asthma cases are linked to indoor allergen sensitisation.
Reduced Sleep Quality
The DTU sleep studies found deep sleep drops significantly when bedroom CO2 exceeds ~800 ppm, with more awakenings and lighter sleep above ~1,400 ppm. Next-day performance suffers measurably.
Respiratory Load
Furniture, paint, gas stoves, and adhesives release VOCs and NO2 indoors. Without fresh air exchange, concentrations climb — linked to impaired lung development, higher infection risk, and worsened asthma and COPD.
A night in your bedroom.
CO2 levels rise steadily as you sleep. In a standard unventilated room, air quality can impact cognitive function and sleep quality.

Current systems don't work
Opening a Window
Brings in fresh air along with Pollen, harmful airborne particulates and noise
Air Purifiers
Filter indoor air from larger particulates, but don't trap CO2 or VOCs
Heating and Cooling Systems
Recirculate the same air. CO2 and VOCs stay trapped inside
ERV Systems
Bring in fresh air but require ducting, drilling and a full renovation

Introducing
air.env
air.env
A smart ventilation system designed to be retrofitted onto any existing window, without the need for drilling or ducting.
It continuously monitors the air inside your room for concentrations of harmful gases like CO2 and VOCs, actively replacing them with fresh HEPA filtered outside air using 2 ultra quiet fans.
The patent pending design allows the system to seal outside noise just like a closed window, while providing ventilation up to 2X better than an open window.
Change the way you rest
Wake up feeling rested
Active CO2 removal allows your respiratory system to work less hard trying to get oxygen.
Sleep through the night
Noise damping design allows for oxygen rich air like outdoors, without the noise that comes with an open window.
Less allergens more fresh air
Built in HEPA filter, removes 99.9% of allergens and pollutants while drawing outside air in.
