Filter Reminder

FILTER REMINDER — HVAC, Water & Air Filter Replacement Tracker

Never forget to replace another HVAC filter, water filter, refrigerator filter, or air purifier cartridge again. Filter Reminder tracks replacement schedules for every filter in your home and sends push notifications before each one is due — so your air stays clean, your water stays fresh, and your appliances last longer.

Add any filter — furnace, AC, fridge water and ice, reverse osmosis, whole-house water, air purifier, humidifier, dehumidifier, range hood, vacuum HEPA, aquarium, pool, or anything custom. Set the replacement interval, and Filter Reminder handles the rest — alerting you in advance and nudging you daily if a filter goes overdue.

WHY IT MATTERS
━━━━━━━━━━━━━━━━━━━━━━━━━━━
A clogged HVAC filter cuts airflow, drives up energy bills, and shortens compressor life. An expired water filter stops removing contaminants. An overworked air purifier just pushes dirty air around. Replacing filters on schedule is the cheapest home maintenance you can do — Filter Reminder makes sure you actually do it.
