Air Quality Monitoring

The air inside your home changes throughout the day. Cooking dinner, opening windows, burning candles, cleaning, or simply spending time indoors can all affect indoor air quality.

Your Jetson Air monitor measures three key pollutants and combines them into an overall Air Score that reflects your home’s current air quality.

Readings update automatically throughout the day, so you can quickly spot changes and understand what might be affecting your home’s air.

Your system needs to be actively moving air, whether heating, cooling, or running the fan, to take a new reading. If it hasn't run in a while, the Air Score will show as Unavailable, along with your most recent reading and when it was measured.

Key elements:

1. Air Score: Your home’s overall indoor air quality, calculated using all monitored pollutants. Also shows when the most recent reading was collected.
2. Air Pollutants (Jetson Care only): View live measurements for PM2.5, CO₂, and TVOC.
3. History (Jetson Care only): Track how your Air Score has changed over the past 7 days.

If your system hasn't been heating, cooling, or circulating air recently, the Air Score will show as Unavailable, along with your most recent reading and how long ago it was measured.

Your Air Score summarizes the overall quality of the air inside your home.

• 🟢 Excellent — Air is exceptionally clean. Conditions are ideal for comfort and everyday living.
• 🟢 Good — Air quality is within a healthy range. Indoor pollutant levels remain within a healthy range for everyday living.
• 🟡 Fair — Air quality is below ideal. Some pollutant levels are elevated. This can happen after cooking, cleaning, or other everyday activities.
• 🟠 Poor — Air quality is poor. Several pollutant levels are elevated and may affect comfort. Improving ventilation or circulating air can help.
• 🔴 Very Poor — Air quality is very poor. Pollutant levels are high and may affect comfort and well-being. Take steps to improve indoor air quality right away.
• ⚪ Unavailable — Your system needs to be actively heating, cooling, or circulating air to take a new reading. If it hasn't run in a while, the Air Score shows as Unavailable, along with your most recent reading and when it was measured.

After your system starts circulating air, it will take a few minutes before you see the current air quality reading. This is to allow time for the the monitor to sample air quality levels and provide an accurate reading.

Your Jetson Air monitor measures three different pollutants because each tells you something unique about the air inside your home.

PM2.5 — Fine Airborne Particles

What it is

PM2.5 consists of tiny airborne particles from sources like cooking, dust, smoke, and outdoor pollution. Measured in µg/m³ (micrograms per cubic meter).

Common sources

• Cooking and frying
• Smoke
• Dust
• Candles and fireplaces
• Scented products
• Outdoor pollution entering your home

Why it matters

These tiny particles can reach deep into the lungs, irritating airways and worsening allergies and respiratory symptoms.

Typical range (µg/m³)

• Excellent: Under 5
• Good: 5 to 11.9
• Fair: 12 to 35.4
• Poor: 35.5 to 55.4
• Very Poor: 55.5+

How to reduce it

Run your kitchen exhaust fan while cooking, replace your HVAC air filter regularly, and improve ventilation when particle levels increase.

CO₂ — Carbon Dioxide

What it is

Carbon dioxide (CO₂) is a gas people and pets breathe out. Levels rise in closed rooms and homes with poor ventilation. Measured in ppm (parts per million).

Common sources

• People and pets
• Closed windows and doors
• Poor ventilation

Why it matters

High CO₂ can cause drowsiness, headaches, and reduced focus. It's often the clearest sign that fresh air isn't circulating well.

Typical range (ppm)

• Excellent: Under 600
• Good: 600 to 999
• Fair: 1,000 to 1,499
• Poor: 1,500 to 2,499
• Very Poor: 2,500+

How to reduce it

Open a window or run ventilation regularly to bring in fresh air and reduce stale indoor air.

TVOC — Total Volatile Organic Compounds

What it is

TVOCs are gases released from products like cleaners, paints, furniture, and scented sprays. Measured in ppb (parts per billion).

Common sources

• Cleaning products
• Air fresheners and scented sprays
• Paint
• New furniture
• Building materials

Why it matters

Elevated levels can cause headaches, eye irritation, and discomfort, especially in poorly ventilated spaces.

Typical range (ppb)

• Excellent: Under 125
• Good: 125 to 599
• Fair: 600 to 1,499
• Poor: 1,500 to 2,999
• Very Poor: 3,000+

How to reduce it

Ventilate when using household products and choose low-VOC or unscented alternatives when possible.

The History section shows how your home’s Air Score has changed over the past seven days.

Watching trends over time can help you identify what affects your home’s air quality, such as:

• Cooking meals
• Cleaning
• Opening windows
• Poor outdoor air quality
• Changes in ventilation

Rather than focusing on individual readings, look for recurring patterns that can help you improve your home’s indoor environment.

A few simple habits can make a noticeable difference when air quality is measured as poor.

• Improve ventilation – Fresh outdoor air helps reduce indoor pollutants and stale air.
• Cook with ventilation – Run your range hood while cooking to remove smoke and airborne particles.
• Replace your HVAC filter – A clean filter captures more airborne particles and helps your system maintain healthy airflow. Learn more about air filters here.
• Turn on Air Circulation – Enable Air Circulation in Fan Settings to keep air moving through your home’s filtration system, even when heating or cooling isn’t running.
• Reduce chemical pollutants – Choose low-VOC paints, cleaners, and furnishings whenever possible, and ventilate after using products with strong odors.
