Filtro: Filter Tracker

Never forget a filter change again. Air, water, vacuum, every filter in one place.

Filtro tracks every filter in your home, air purifier, HVAC, fridge water, range hood, humidifier, car cabin, and reminds you exactly when it's time to change them.

Add a filter in a few taps. Filtro remembers the date and reminds you before it's overdue, nothing else to manage.

See what's overdue, due soon, and all clear at a glance. Mark a filter as changed with one tap, and keep a full history of every change.

Filtro Plus unlocks unlimited filters (free covers 2), a Home Screen widget with the next change always in view, spare filter inventory with low-stock alerts, and a photo/buy-again link so you never guess the size again. One-time purchase, no subscription.
