How to Log Changes for Compliance
Maintaining records is essential-especially for regulated industries like healthcare and education.
- Use a logbook or digital tracker to record the date and type of filter changed.
- In regulated settings (e.g., healthcare or schools), show the logs during inspections.
- Set calendar or text reminders - most staff find Google Calendar or Outlook easiest for this.

Tips to Train Staff
Proper staff training prevents system strain and ensures compliance:
- Teach team members to spot dirty, damaged, or sagging filters.
- Make a monthly check part of your opening or closing checklist.
- Encourage staff: “If it smells bad or airflow drops, alert management.”
Seasonal Reminders
Different seasons stress filters in unique ways:
- Spring: Pollen can clog filters quickly - check monthly.
- Summer: Facilities with air conditioning force the filters to work harder.
- Fall: Expect extra dust, especially when windows are open.
- Winter: Heating cycles increase filter use and demand.
