F.A.Q
Got a question? We've got answers! Our team of experts is here for you Monday to Saturday, 9 AM to 6 PM.
How does the Puure filtration system work?
Puure is a cutting-edge water filtration system that uses advanced technology to eliminate harmful particles and pollutants. It integrates an activated carbon filter and multi-stage filtration designed to reduce chlorine, heavy metals, and odors. Materials certified NSF/ANSI 42 for safety. Designed for convenience, its smart functionality lets you switch between filtered and unfiltered water in just a second.
Does Puure filter out the good minerals too?
No. Puure uses a multi-barrier system — not reverse osmosis. It reduces harmful contaminants like PFAS, chlorine and heavy metals, while keeping the natural minerals your body needs — calcium, magnesium, potassium. Cleaner water, not empty water.
How long does each filter cartridge last?
Each cartridge lasts around 3 months.
Can I cancel or change my subscription anytime?
Our subscriptions are completely flexible—no commitments! You can modify or cancel anytime, up to 48 hours before your next order, directly from your account or by emailing us at customercare@puurefilters.com
Is the Puure system covered by a warranty?
Yes! Puure is built to last and comes with a 2-year warranty. If there’s an issue, we’ll replace it free of charge.
Do I need to subscribe or can I buy once?
Both options are available. The subscription saves you money and ensures fresh cartridges arrive on time — but you can also buy a one-time cartridge pack anytime. No pressure.
Is the subscription flexible?
Fully. Change frequency, quantity, pause or resume — all from your personal dashboard in 1 click. Switch between 6-month and yearly plans anytime.
How do I manage my subscription?
