Filter Flow - Text message reminder to replace furnace filter with confirmation.

For homes, rentals, and whole portfolios

Never think about a furnace filter again.

Tell us your filter size once. A year of filters ships to the door, and whoever changes it — you, a tenant, a building contact — gets a text the day it's due. No reminders to set, no trips to the store, no wondering what size it was.

Swapped and confirmed

A friendly text the day it's due. One tap confirms it's in — and you'll know it got done.

Landlords & property managers

Filters get changed. You get the receipt.

Your tenant gets the text and taps to confirm. You get a text back saying it's done — or that it isn't, so you know which unit to check. Every confirmation is logged per property, ready for turnover or an owner report.
