PUR Chrome Advanced Water Filter, $23 after 15% coupon | PUR Bluetooth Water Filter, $38 after 15% coupon

If you don’t want to dedicate a watermelon-sized chunk of fridge space to a Brita pitcher, this easy-to-install faucet attachment is 15% off on Amazon today with an on-page coupon.

The PUR Advanced can filter up to 100 gallons of water per filter, and with replacements available for less than $10 each (or less when you buy in bulk), that comes out to about $.01 per 16 ounce bottle of lead, asbestos, and sediment-free water.

The coupon also works on the Bluetooth model, which syncs with your phone to track your usage, water intake, and filter lifespan.
