How it works

How It Works

Set it once. We handle the rest.

Filterflow turns furnace filter replacement from a recurring chore into a system that runs itself. Set up each unit once, and we take care of delivery, tenant reminders, and install confirmation — every month, automatically.

1

Set up your property

Add each unit to your account and set its filter size, MERV rating, shipping address, and delivery cadence — once. Whether you manage one rental or fifty, every unit lives in a single dashboard. No spreadsheets, no calendar reminders, no recurring mental overhead.

2

Filters ship automatically

Every month — or on whatever cadence you choose — we ship the right filter to each unit's address. Correct size, correct MERV rating, delivered to your tenant's door. No reordering, no hardware-store runs, no forgetting. Free shipping on every subscription order, typically arriving within 3–5 business days.

3

Tenants get a friendly reminder

The day the filter arrives, your tenant gets a text: a friendly heads-up that it's time to swap, with quick install instructions and a confirmation link. One short message, optimized for tone and timing. Tenants reply DONE or tap the link once they've installed it. They can opt out anytime by replying STOP.

4

You get confirmation

When your tenant confirms the swap, you're notified instantly — no chasing, no wondering whether it got done. If a tenant doesn't respond, we send one polite follow-up. Still no confirmation? You're alerted so you can follow up directly. Every install is tracked, giving you a clean maintenance record for every unit.

Why it works

Protects your HVAC investment

Clogged filters are a leading cause of HVAC strain and breakdowns. Regular replacement keeps systems running efficiently and avoids costly repairs.

No more chasing tenants

The SMS reminders and confirmation tracking mean you're not sending "did you change the filter?" texts every month.

Better air, happier tenants

Fresh filters mean cleaner air and a well-maintained home — a small touch that tenants notice and appreciate.

A record for every unit

Every shipment and install confirmation is logged, giving you clean documentation of maintenance across your portfolio.
