The most advanced indoor air quality system significantly reduces your home's energy consumption.

Sendal's Breathe service fights toxins in the air to keep you safe at home.

Radon icon

Radon You can't see or smell it, but long-term exposure to radiation is the lead cause of lung cancer in non-smokers.

Particulate matter icon
Particulate Matter

(PM1, 2.5,10) Fine solids that reach deep into your lungs can cause short-term discomfort.

VOC icon

(VOCs) are airborne chemicals emitted by everyday items that are harmful to our health and are common in homes.

CO2 icon
Carbon Dioxide

CO2 is created when we breathe and elevated levels have short-term effects on our ability to function and sleep.

Humidity icon

Humidity can worsen indoor air quality by promoting mold growth, dust mites, and volatile organic compound (VOC) emissions, which can lead to respiratory issues, allergies, and discomfort.

Outdoor Air

Outdoor air may introduce pollutants, allergens, and radon, increasing health risks like respiratory issues and lung cancer.

Clean air is important.

"EPA studies of human exposure to air pollutants indicate that indoor levels of pollutants may be two to five times — and occasionally more than 100 times — higher than outdoor levels... most people spend about 90 percent of their time indoors."

Breathe has you covered.

Maximum flexibility for managing all aspects of indoor air quality
Predictive and responsive to various factors inside and outside of the home
Saving 40-60% of energy associated with ventilation
Controls pollutants, adapts ventilation strategies, and filters airborne particulate matter
Frequently Asked Questions

Here's what thought leaders have to say.

“With Breathe, we are revolutionizing how we approach indoor air quality and reducing energy consumption.”

Dennis Webb, VP Fulton Homes

“The Breathe service approach to managing energy and indoor air quality is exactly in line with our path to an intelligent home.”

Stefan Orenda, CTO Mandalay Homes

“The Breathe service has transformed our indoor air quality solution by giving us automatic, intelligent, and predictive control of our home’s ventilation and dehumidification system.”

Shawn D. Jessup, Builder

“I worked with Sendal to get a monitoring system in place that had the ability to control my ventilation system based on the actual IAQ...the IAQ in our house has improved dramatically, and it all happens automatically through their intelligent app. It’s a fantastic system!”

Dodson Harper, PE SE, Resource Engineering Group
