How often to change bed sheets, replace a toothbrush or an HVAC filter
As a general rule, wash bed sheets every 1-2 weeks, replace a toothbrush every 3 months and change an HVAC filter every 1-3 months. Knowing the interval is the easy part. Remembering when you last did it is the hard part.

How to actually stay on schedule
- Log the date every time, instead of trusting memory.
- Give each item a cycle and get a reminder when it's due.
- Check your real average gap and adjust the cycle to your life.
