Terms of Service
Effective July 30, 2026
1. What we provide
MySmartFilter ("we", "us") provides a hardware pressure sensor, a monitoring dashboard, alerting, and an optional automatic filter-replacement ordering service (together, the "Service"). By creating an account or installing a device you agree to these terms.
2. Your account
You're responsible for the accuracy of the information on your account, for keeping access to your sign-in email secure, and for all activity under your account. You must be 18 or older and able to enter a contract.
3. Auto-ordering and payments
If you enable auto-ordering, you authorize us to charge your saved payment method for a replacement filter (at the price shown in your filter preferences, plus shipping shown at setup) when your device's readings meet the replacement threshold. We email you before each auto-order with a one-click cancellation link and wait at least 24 hours before charging. You can disable auto-ordering, change your preferred filter, or remove your card at any time in Settings. Payments are processed by Stripe; we do not store card numbers.
4. Shipping and returns
Filters ship to the address on file. Unopened filters may be returned within 30 days of delivery for a refund of the purchase price; contact support@mysmartfilter.com. Damaged or incorrect items are replaced at no cost.
5. The device and estimates
Energy-cost figures shown by the Service are estimates derived from your device's pressure readings and the system details you provide (airflow, blower type, electricity rate). They are provided for guidance and are not a utility bill, a warranty of savings, or professional HVAC advice. The device is a monitoring accessory: it does not control your HVAC equipment, and it is not a substitute for professional maintenance or safety inspections.
6. Acceptable use
Don't attempt to access other users' data, probe or overload the Service, resell API access, or use the Service in violation of law. We may suspend accounts that do.
7. Warranty and liability
Hardware is covered by a 1-year limited warranty against defects. Otherwise the Service is provided "as is" to the maximum extent permitted by law; we disclaim implied warranties and are not liable for indirect or consequential damages, including damage to HVAC equipment or property. Our total liability is limited to the amounts you paid us in the 12 months before the claim.
8. Changes and termination
You can delete your account at any time in Settings, which stops all monitoring and auto-ordering. We may update these terms; if the changes are material we'll email you at least 14 days before they take effect.
