Why does Windmill ship in bulk?Updated a month 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.
