The problem

Filters don't fail on a schedule.

Homes, buildings, usage patterns, equipment, weather, and filters are all different. Fixed replacement schedules cannot tell you what is actually happening inside the system.

Filter Fox helps replace assumptions with measured information.

How it works

Three steps, then you simply know.

01

Install

Place the Filter Fox sensor on the HVAC system.

02

Monitor

Airbryt continuously analyzes airflow and pressure behavior.

03

Know

Receive useful insights and alerts when conditions change.

What Filter Fox sees

Measured, not assumed.

Filter condition

Measured loading and restriction, not a countdown from the last change.

Airflow

Live airflow readings compared against the system's learned baseline.

Pressure

Static pressure across the system, tracked continuously.

System trends

Longer-term behavior so gradual change is easy to see.

Alerts

Clear notifications when readings move outside normal range.

The Airbryt platform

The sensor is only the beginning.

Every Filter Fox connects to the Airbryt platform, where system data becomes trends, alerts, and actionable HVAC intelligence.
