HomeCleanse’s new air quality monitor tracks what most consumer devices miss

Most people associate air quality with outdoor problems like wildfire smoke, ozone alerts, and city pollution. But indoor air is often significantly more polluted than the air outside, and most homes have no way to detect it. HomeCleanse, a mold remediation company, just launched the Guardian to address that gap.

As wellness culture shifts from reactive to preventive, your home environment is the next frontier — and air quality is one of the few variables you can actually control.

How the Guardian works

The Guardian tracks a broader range of pollutants than most consumer-grade devices like mold spores, mycotoxins, fine particulates down to 0.1 microns, VOCs, CO₂, and ozone. It can even track humidity levels and temperature, surfacing everything through a dedicated app you can check from anywhere. The brand also says it can detect airborne viruses like COVID and influenza.

When a reading crosses a threshold (humidity above 60%, CO₂ above 1,000 ppm, for example), you get an alert. So does HomeCleanse’s team, who will call you directly to walk through next steps. The device covers up to 5,000 square feet, so one unit can handle most whole-home setups.

A two-hour battery backup keeps it running through power outages, and eight months of data stored onboard means it keeps logging even when your Wi-Fi goes down.
