Why does Windmill ship in bulk?Updated 23 days ago

We ship in bulk (annual packs) to pass the savings directly to you and help decrease our carbon footprint. Many filter companies ship a filter to you every time you need to replace it. We'll just text you instead. This not only means fewer deliveries to your door (which equates to a lower carbon footprint) but this also makes the filter always available whenever you may need it. Free shipping, always.
