Work out when an HVAC filter is next due from its last change and a service interval — and see at a glance whether it’s ahead, due soon or overdue.
traqR turns filter intervals into recurring scheduled jobs and reminders across every site, so changes never get forgotten.
Start free trialFilter life depends on the environment — a clean office runs far longer than a dusty workshop. Pick an environment or enter your own interval.
Enter when the filter was last replaced. The next-due date is that date plus the interval.
The result flags whether the change is comfortably ahead, due soon, or overdue — so you can plan the visit before airflow suffers.
It depends on the filter type and environment. A basic filter in a clean space might last three months, a commercial system two, and a dusty industrial setting monthly, while higher-grade bag or HEPA filters in filtered plant can run six months or more. Always check the manufacturer’s guidance and the pressure drop.
A clogged filter increases resistance, reducing airflow and forcing the fan to work harder, which wastes energy and can cause coils to freeze or the system to trip. It also lets more dust through and hurts indoor air quality. Changing on schedule keeps the system efficient and healthy.
Both are used. A time-based schedule is simple and easy to plan, while measuring the pressure drop across the filter tells you its actual condition. Many operators schedule changes but also check pressure drop to catch filters loading up early.
This planner works out the next date for one filter. To manage many filters across sites, a job-management system that turns intervals into recurring scheduled jobs and reminders — like traqR — keeps every change on track.
This planner is a general scheduling aid. Actual filter life depends on the filter type, environment and measured pressure drop, and manufacturers’ guidance should be followed. Use it to plan, and verify condition on site.
