— 03 Honest answers

Quick questions.

Does this filter fit my Osma Glacier 1.8L pitcher?
Yes. Same filter that ships in every Osma bundle. One filter cartridge, one model — fits every Osma Glacier 1.8L pitcher made since launch.
How long does one filter last?
Up to 150 gallons (568 L) or ~3 months for a family of four drinking mostly filtered water. We email a replacement reminder at 2.5 months automatically. Hard-water markets (Phoenix, Las Vegas, Dallas) may see ~110 gallons — see the 3-star review on the main pitcher page.
Is this the same as the filter in the pitcher bundle?
Yes. Identical SKU, identical Multi-Capture™ carbon block, identical NSF certification. Buy the bundle if you don’t own a pitcher yet, buy these refills if you do.
What does "third-party verified" mean for replacement filters?
We test the production line annually. Same protocol as the original certification: NSF/ANSI 53 + 401 + P473 by an independent accredited laboratory.
Can I cancel an auto-reminder email?
Yes — one click from your account or any reminder email. No subscription, no auto-billing, no minimum.
Bulk-buy — is the 4-pack really cheaper?
Yes. The 4-pack works out to $39.75 per filter vs $49 single and $44.50 in the 2-pack. ~12 months of filtered water per 4-pack — one purchase a year.
