Philips Avent Anti-colic Review (2026)
In-depth review of the Philips Avent Anti-colic with AirFree vent: how it works, cleaning, and who it suits.

Philips Avent Anti-colic Bottle with AirFree Vent
Keeps the nipple full of milk, not air, in any feeding position.
Our verdict
The Avent is the pragmatic vented bottle: the AirFree vent genuinely keeps the nipple full of milk in any hold, and the part count stays manageable. The trade-off is venting depth: it cannot match Dr. Brown's two-piece system for the gassiest babies, and the vent must stay submerged to work. Buy it when you want real anti-colic function without dreading the wash.
What we like
- AirFree vent keeps the nipple full of milk even when the bottle is held horizontal, cutting air ingestion.
- Fewer parts than Dr. Brown's: vent, nipple, and bottle, which shortens the 3 a.m. wash.
- Nipple shape is designed to mimic breastfeeding latch, helpful for combo feeding.
What to watch out for
- The AirFree vent must stay submerged to work, so very small feeds in a large bottle defeat it.
- Nipple flow options are fewer than Dr. Brown's six-level range.
- Wide-neck design takes more cabinet space than narrow bottles.
Who it is for
Parents who want vented feeding with simpler cleaning, and who feed in varied positions.
The AirFree vent in practice
The AirFree vent is a small cup-shaped insert that sits in the nipple and draws milk from the bottom of the bottle, keeping the nipple full even when the bottle is held nearly horizontal. The practical win is positional freedom: you can feed upright, which itself reduces air swallowing, without the nipple gulping air. The constraint is that the vent must stay below the milk line, so tiny feeds in the 9 oz bottle leave it high and dry. Size the bottle to the feed.
Cleaning and part count
Three main parts: bottle, AirFree vent, nipple and collar. That is meaningfully fewer than Dr. Brown's five, and the wide neck admits a bottle brush easily. All parts are top-rack dishwasher safe. For parents doing six-plus washes a day, the difference between three parts and five is not trivial over months.
Nipple design and flows
The nipple uses a ribbed texture designed to prevent collapse during feeding, a real issue with some vented designs where the baby's suction flattens the nipple. Four flow levels from newborn to fast cover the standard progression, though the range is narrower than Dr. Brown's six. The latch shape is broad-based, which combo-feeding families tend to prefer.
How it stacks up
Against Dr. Brown's Options+, the Avent trades maximum venting for washing sanity: pick Avent when gas is moderate and you value your sleep-time. Against the Tommee Tippee Closer to Nature, the Avent vents more effectively and offers the AirFree positional advantage, while Tommee wins clearly on price. The Avent sits in the sensible middle of venting, cleaning, and cost.

Questions, answered
Does the AirFree vent really work horizontally?
Yes, provided the vent stays submerged in milk. The design draws from the bottle bottom, so horizontal and upright holds both keep the nipple full. Just match bottle size to feed size so the milk level covers the vent.
Can I use the bottle without the vent?
Yes, the nipple has its own anti-colic valve and the bottle functions without the AirFree insert, which is handy once the baby outgrows the gassy phase.
What sizes are available?
4 oz, 9 oz, and 11 oz. Start newborns on the 4 oz so the vent stays submerged in small feeds, and size up as feeds grow.
