1. Locks milk in, keeps air out, for easy upright feeding: The teat stays full of milk, even when the bottle is horizontal, so your baby can drink in a more natural, upright position.This can help reduce reflux, aid digestion, and make feeding time more comfortable for you and your little one.
2. Teat stays full of milk, not air: Our unique AirFree™ vent draws air away from the teat, so your baby swallows less air as they drink. This can help reduce common feeding issues such as colic, reflux and gas.
3. Easy to clean & assemble, as AirFree™ vent is a single piece: The AirFree™ vent can be easily assembled with any Philips Avent Anti-colic and Classic+ bottle. Also as the vent is one single piece, cleaning is a breeze.
4. Simple to use: To start, fill the bottle with milk, place the AirFree™ vent over the rim, and screw on the teat. Tilt the bottle downwards once to fill the teat, and you're ready to go. When feeding, make sure the AirFree™ vent stays on top. The teat will stay full of milk, even when it's horizontal, for easier upright feeding.
5. Compatible with all sizes Philips Avent Anti-colic bottles: The Philips Avent AirFree™ vent is compatible with our 4oz / 125 ml, 9oz / 260 ml and 11oz / 330ml Philips Avent Anti-colic bottles. The AirFree vent is not compatible with the Natural bottles.

Make sure to clean and sterilize all parts before use.
Fill your Philips Avent Anti-colic bottle with milk.
Place the AirFree vent between the bottle and the nipple.
Fill the nipple by holding the bottle upside down.
Make sure the AirFree vent is faced upwards while feeding your baby, aligning the bottle with the nose of your baby.
