Warranty Repairs and Return Requirements
If your product qualifies for repair or replacement during the warranty period, NU Aqua Systems will replace any and all parts of the affected product according to the terms of this warranty. If necessary, NU Aqua Systems can replace the entire system.
Please keep in mind that the warranty does not cover labor costs, freight charges, or other local third-party charges unless NU Aqua Systems approves those costs in writing beforehand.

No, NU Aqua System warranty coverage can't be transferred.
Warranty coverage only applies to the original purchaser. Coverage ends when the product leaves that person’s possession.

- The original seller
- The original purchaser
NU Aqua may request this proof during a claim.

When does warranty coverage begin?
Warranty coverage begins on the date your NU Aqua system is delivered.
You'll also need to register your system after delivery. Registration helps us confirm your product information and process future warranty claims faster.
What does “Lifetime Warranty” mean?
The Filter Club Lifetime Warranty applies to the expected lifetime of the product. It does not refer to the purchaser’s lifetime.
The expected lifetime of eligible systems is around 10 years from the delivery date.
However, at NU Aqua Systems’ discretion, we may approve warranty claims after the product’s expected 10-year lifetime.
All Filter Club subscription, installation, operational, and maintenance requirements must remain satisfied.
What happens to my warranty if my Filter Club payment fails?
If a payment fails, you can contact us with updated payment information and your lifetime coverage will continue.
If you're unable to provide an updated payment, your lifetime warranty coverage will be subject to suspension. Ongoing non-payment may result in lifetime warranty coverage being terminated.
What happens to my warranty if I cancel my Filter Club subscription?
If you voluntarily cancel your subscription, your lifetime coverage becomes inactive.
You can, however, pause or reschedule your payments. This keeps coverage active without canceling your subscription and ending coverage altogether.
Note: Paused Filter Club memberships resume coverage upon payment.
