If you’re a Dr. Brown’s household staring down a pile of bottles with their notoriously fiddly anti-colic vent systems, the Baby Brezza Bottle Washer Pro is one of the best machines you can buy — not just in spite of the vent tubes, but partly because of them. Here’s exactly what you need to know before committing.
Baby Brezza

Reviewers who tested the Bottle Washer Pro with Dr. Brown’s Options+ bottles in both small and large sizes found everything fit comfortably. This isn’t a coincidence — Baby Brezza clearly designed this machine with Dr. Brown’s in mind. The lower rack has dedicated placement slots specifically for Dr. Brown’s green vent tubes, and the side spray jets clean them inside and out. Most competing washers skip this entirely.

Dr. Brown’s
Natural Flow Anti-Colic Options+ Wide-Neck Bottles — 5 oz (4-Pack)
The shorter newborn starter bottle. Fits easily with either center rod — the shorter rod actually gives you more headroom above.

This is what most people miss and why the “does it fit?” question comes up so often. The Bottle Washer Pro ships with two center rods of different lengths. The shorter rod makes the upper rack roomier and works well for compact, wide-mouth bottles. The longer rod raises the upper rack to create extra clearance on the lower rack — which is exactly what you need for the taller 9 oz Dr. Brown’s wide-neck bottles.
What About the Vent System Parts?
Dr. Brown’s anti-colic bottles have those notoriously fiddly internal green vent inserts — and the Bottle Washer Pro handles them better than almost any other machine. The lower rack has dedicated slots with side-facing jets that clean the tubes thoroughly inside and out, which is a feature most competing washers don’t have.

Not compatibleThe Bottom Line
Yes, Dr. Brown’s tall bottles fit in the Baby Brezza Bottle Washer Pro — the key is using the longer center rod for the bigger 9 oz sizes. Beyond the fit question, this machine is actually one of the most Dr. Brown’s-friendly options on the market thanks to its dedicated vent tube slots. The only parts you’ll still need to hand-wash are the collar caps, but that’s a true for nearly every bottle washer out there.
If you’re already a Dr. Brown’s household (or planning to be), this pairing works well. Just remember to stock up on Baby Brezza’s detergent tablets — the warranty requires them.
