Four things it does that you can’t.

Two sensors that see what you can’t, a bar anyone can read, and an app only when you want it.

Infrared for CO2

Light shines through a tiny chamber. CO2 soaks some of it up. The less light that gets through, the more CO2 is in your room. Infrared is the type of sensor made to measure CO2 itself.

Laser for fine dust

A small fan pulls in room air. A laser shines across it, and every tiny bit of smoke or dust flashes as it passes. The sensor counts the flashes. So you see when cooking or candles fill the room.

One bar. No charts.

A short green bar means fresh air. When it climbs into orange or red, open a window and watch it drop.

Groggy at 7am? Foggy by 3pm?
It might not be you. It might be your room.

Shut the door for a night of sleep or a workday, and the air you breathe out builds up hour after hour. You can’t see it. You can’t smell it. You only feel it.

About 4×

More CO2 in a bedroom with the window shut than with it open, in one sleep study. People fell asleep faster with it open.

50%

Lower scores on thinking tests for office workers in stale air than in fresh air, in one study.

2 to 5×

Some air pollution is 2 to 5 times worse inside than outside, says the U.S. EPA. And we spend about 90% of our time inside.

Dark bedroom at night with the door closed

Trapped with every breath.

Every breath out adds CO2. Shut the door for the night and it has nowhere to go. In one sleep study, a closed bedroom passed 2,500 ppm.

Dust that slips past your nose.

Cooking, candles and heating fill the room with fine dust. Your nose stops big dust. Most fine dust slips past it, deep into your lungs.

Mist from a spray bottle drifting into the air

Fumes you stop noticing.

Sprays, paint, new mattresses and furniture give off fumes. After a few minutes you stop smelling them. They can still be there.

You can’t fix what you can’t see. CalmFront Air puts it on one bright screen.

The story behind CalmFront

Built to end the window argument.

For two years I woke up tired. Eight hours of sleep felt like four. Dry throat, dull headache, two coffees before I felt normal.

I changed my mattress. I bought blackout curtains. I took magnesium before bed. Nothing really helped.

Then I read about CO2 building up overnight in modern homes. New homes are sealed tight to save heat. Great for the heating bill. Bad for fresh air.

So I looked for an air monitor. Some low-priced ones didn’t say what sensor was inside. Others cost $300 or more and had no screen, so I had to open an app just to see my own air. And every time I opened the window in winter, we argued about letting the heat out.

So I started CalmFront. I picked a monitor with an infrared CO2 sensor and a laser dust sensor, with a big screen anyone can read from across the room. No phone needed. No subscription. When the bar climbs, everyone can see it’s time to open the window.

“You should be able to look across the room and know if the air you breathe is fresh.”

David, founder of CalmFront

Plug in. Glance. Air out.

Fresh air for your workday. Fresh air for your night.

1
Plug in.

Put it on a desk, nightstand or wall and plug it in. The sensors start within minutes. No battery to charge.
2
Glance.

Six readings on one bright screen. The bar under CO2 gives the answer: short and green is fresh, long and orange is stale.
3
Air out.

Crack a window, open the door or turn on the range hood. Watch the number and the bar fall.

The two-night test

Find out in two nights. Or send it back.

Night one: sleep as you always do. Night two: crack the window an inch or two. Compare the two lines in the morning. Now you know if your bedroom is part of the problem, and which fix works.

Dark and quiet at night. Loud when you want it.

Night

Turn the screen light off and mute the buzzer in the app. The room stays dark and quiet. It keeps measuring, and you check the night in the morning.

Day

Set your own alert levels. If smoke from the kitchen climbs while you’re in another room, the buzzer tells you.

Inside

We tell you what’s inside. Before you buy.

An infrared sensor for CO2. A laser sensor for fine dust. A fumes sensor. A Wi-Fi module. And power from the wall, so it never sleeps to save a battery.

Sensor types and ranges are from the maker’s spec sheet. It’s a home monitor for spotting changes in your air, not a lab tool.

Everything people ask before they buy.

Does it clean the air?

No. It’s a monitor. It doesn’t take dust, smoke or gases out of the air. It tells you when your air needs attention, so you can act: open a window, turn on the range hood, or run a fan or purifier.

I have an air purifier. Do I still need this?

A purifier cleans the air that’s already in the room. It can’t bring fresh air in. Filters catch dust. They don’t take out the CO2 from breathing. Only fresh air does that. CalmFront Air shows both numbers: the dust your purifier should bring down, and the CO2 that only fresh air brings down.

Do I need Wi-Fi or the app?

No. The screen works on its own the moment you plug it in. Wi-Fi and the free app add remote numbers, history, alert levels and the backlight switch.

Is there a subscription?

No. The app is free. No monthly fees.

Is the screen too bright for a bedroom?

The app has a backlight switch. Turn the screen light off at night. It keeps measuring, and you check the numbers in the app.

Does it beep or make noise?

It has a buzzer for alerts. You set your own alert levels, and you can mute it. The dust sensor pulls air through with a small fan. In a silent room you may hear a faint hum up close.

Does it run on batteries?

No. It plugs in, so it measures around the clock and never needs charging.

How accurate is it?

It’s a home monitor for spotting changes in your air, not a lab tool. The CO2 sensor is infrared, the type made for measuring CO2. Read the dust and fumes numbers as trends. For the best readings, put it at breathing height, away from windows, vents, steam and direct sun. The CO2 sensor resets itself about once a day, so let fresh air into the room once a day.
