About this Product
  • Fits most microwaves
  • Super-fast process
  • Holds up to four 9-oz bottles or two 11-oz bottles


Think about this: in the time it takes to grab the mail and sift through it, you could have germ-free bottles. The sterilizer reaches temps higher than your dishwasher and the items inside remain sterile for 24 hours when the lid is unopened.

All it takes is loading the sterilizer, adding water, locking the lid, and two minutes later you have steam-purified bottles. It also works with pacifiers, breast pumps, milk storage cups, and lids.

Although touted as toteable for trips, this sterilizer will probably be too big for hotel-size microwaves (in which case sterilizing bags are better).

Do you need a sterilizer? Parents with immune-compromised babies swear by sterilizers, but other families find they do not use them enough to be worth it. If you are on the fence about whether to get a hefty (and pricey) electric sterilizer, a microwave version is a good in between since they’re easy to use and smaller than electric ones.


  • BPA-free plastic

I love it and use it for a lot of things, like pump parts and other bottles, pacifiers, baby dishes and more!! Not the easiest to store, but worth the money. It works well with most bottles and plenty of other things. Faster than the stove and doesn't take up space in the dishwasher, or get food stuck to baby items like ours sometimes does.

Makes keeping bottles clean and ready to go so easy.

It is SO easy to use! Load with pump and/or bottle parts, add water and run for two minutes in the microwave. I loved it so much my husband had to have an intervention to get me to stop using (you don’t need to sterilize as often after 3+ months).

Never used it; not necessary if access to soap and warm water available.

It’s great, serves its purpose to sterilize and is easy to use. Only thing is that it’s hard to store because it takes up a lot of space.

Doesn't work well with larger bottles.

So quick so easy - sure beats boiling! I used this for bottles and syringes we had to keep clean daily due to an immune deficiency. With everything we have to do daily this made my life so much better!

Easy to use and takes up less space than a counter top sterilizer. I hide it inside the microwave when I’m done using it.
