Frequently Asked Questions
What does the filter remove?
The 0.1-micron hollow-fiber membrane removes 99.99%+ of waterborne bacteria, parasites, and microplastics. It is not designed to desalinate seawater or remove dissolved chemicals.
Where can I use it?
Streams, lakes, ponds, rainwater, and questionable taps. Sip directly through the straw or fill the included pouch.
How long does one filter last?
Up to 400 gallons with regular backflushing using the included syringe. There’s no shelf life — store it until you need it.
How fast is shipping?
Free shipping on every order. Processing 1–2 business days, delivery typically 7–11 business days, with tracking.
What if I don’t like it?
You’re covered by our 90-day money-back guarantee. Email support@wellrove.com and we’ll take care of it.
Does it need batteries or power?
No. It’s fully mechanical — it works the same during an outage as on a sunny day.
