What If the Next Wellness Metric Is in the Air?

About Altos and what the device actually measures 

Altos is a portable CO2 tracker that helps people understand when the air in a room may be affecting their focus, energy, sleep, and comfort. The device measures CO2, temperature, and humidity, and its iOS app translates the readings into a simple Brain Fuel score with practical suggestions: open a window, take a break outside, move to another room. 

Two things are worth stating clearly. Altos measures carbon dioxide, not carbon monoxide. And it is designed as a wellbeing and performance product, not a medical or safety device. Its value is in making an invisible daily factor visible, without asking users to interpret raw sensor data on their own. 

The challenge: a wellbeing factor almost nobody tracks 

People increasingly measure sleep, recovery, stress, and activity. Yet most of them miss one variable that shapes every one of those metrics: the air in the rooms where they work, sleep, study, and exercise. A home office with the door closed, a bedroom with the window shut through the night, a small meeting room with too many people in it. CO2 builds up quietly, and the effects show up as afternoon fatigue, a foggy head, or a night of sleep that never quite restores. 

Altos needed to reach a U.S. audience that was already engaged with health data and open to a new layer of it. Three things had to happen at once: 

• Explain an unfamiliar product category without turning the message into a spec sheet.
• Reach people who already care about focus, energy, and sleep quality. 

• Turn that attention into qualified visits to getaltos.com.

The solution: talk about the experience, not the sensor 

Welltory promoted Altos through its own communication channels, where users already track how they sleep, recover, and handle stress. That context did the heavy lifting: the offer did not interrupt strangers, it reached people whose daily goals already matched what Altos is built for. The campaign combined: 

• Targeted emails to health-conscious Welltory users in the U.S.

• Stories placements inside the Welltory app. 

• Banner placements tested in several creative variants. 

•Messaging built around familiar moments rather than measurements: losing focus in a home office, feeling drained in the afternoon, or waking up less refreshed after a night in a poorly ventilated bedroom 

Because the recommendation came through a platform users trust with their health data, a new product category borrowed credibility it had not yet built on its own. Welltory tested banner variants side by side and leaned into the creatives that performed. 

The results: strong engagement from a high-intent audience 

The campaign exceeded its planned reach and delivered click-through rates well above typical display benchmarks. 

• Banner click-through rates of up to 6.9%, with the best-performing creatives driving the bulk of website traffic. 

• Email open rates above 70%, confirming how attentive Welltory's audience is to wellbeing content. 

The campaign translated strong engagement into qualified traffic to the Altos website. Just as importantly, it showed that indoor air can hold its own next to sleep, stress, and recovery in the minds of health-conscious users.

What this campaign showed 

Indoor air resonates with health-conscious users when it is framed as a practical part of daily wellbeing rather than as a technical metric. For people already focused on sleep, recovery, focus, and energy, Altos adds an often-overlooked layer: the environment around them. The Welltory campaign proved that this layer is not a hard sell once the message speaks to experiences people already recognize.
