I bought this breast pump to replace my old Avent Isis manual breast pump which was broken. I was contemplating whether to buy a replacement part or try the new Avent Comfort. And finally took a plunge on buying the newer model.
How’s my experience with Avent Comfort manual breast pump? Here’s my detailed reviews.

Overview
Avent Comfort breast pump is a newer range of Philips Avent breast pump. It is designed to rival performance of its older model, Avent Isis, while at the same time address some problems of the older model. Here’s a few specifications of this breast pump.
Breast pump type: manual
Single/double: single
Suction adjustment: manual (by piston)
Speed adjustment: manual
Breast flange inner diameter: 28 mm (without massage cushion), 21 mm (with massage cushion). Large massage cushion (with inner diameter of 24 mm is sold separately)

Weight: 13.1 ounces
Available at: Amazon
More specifications can be found here.
What you get out of the box:
- Avent comfort manual breast pump
- Avent natural feeding bottle (4oz) + sealing disc
- Avent natural teat (newborn size) + teat cap
- Two packs of breast pad sample (day and night, 2 pcs each)
Highlights
The most promised highlight of this breast pump is mentioned in the slogan, ‘pumping with comfort’. When other breast pump models require the user to lean forward to prevent milk spillage from breast flange, Avent Comfort model claims that it can be used in a relaxed-upright position, which is much more comfortable, and as we know, more comfort means more milk.
Other than this, Avent Comfort model has been redesigned such that it does not bear the same problems its older model has, which include:
- NO Milk trapped under soft-petal massage cushion. The new massage cushion is thicker and firmer and with Avent Comfort, I’ve never experience milk goes under the cushion anymore
- NO Milk collected under diaphragm. Avent Comfort is smartly designed such that milk will go straight into the bottle instead of accumulating in the pump neck.
- Two different sizes of soft-petal massage cushions. Older model only has one-size-fit-all massage cushion, which makes pumping hurts for woman with large nipple due to poor fitting. With the availability of large-size massage cushion, more mothers will benefit using the breast pump.
- Larger duck-bill valve. New Avent Comfort breast pump uses a big duck-bill valve which is easy to insert and pull out, unlike the older model which has tiny star-shape valve which falls easily into the bottle.
Some other features that I like from this breast pump:
- Less part to wash

Much less parts to fiddle with is a plus of Avent Comfort breast pump
- Compact and portable, great for travelling
- Massage cushion to for better milk flow
Cons
While this breast pump has been successful in addressing the problems of the older model, Avent Comfort manual breast pump is lack of my favorite features of the old Avent Isis. These include:
- No base cover. The old Avent Isis has two covers to keep the pump clean and sterile when not in use, one for flange and one for the base of pump body. I was disappointed when I could not found the base cover for Avent Comfort. This means you need to resort to using ziplock bag to keep the breast pump clean, which is an added hassle.
- Shorter breast flange tunnel. This may not be an issue for most mothers, but I found out that my nipple will hit the end of breast pump tunnel while pumping, reducing the effectiveness of the suction. With ineffective suction, you’ll get less milk and breast is not emptied properly.

See how short is the distance from the opening of the tunnel to the back wall
- Not enough flange size variation. Ok, perhaps I am asking too much here. While it is true that having two different sizes (normal and large massage cushion) is better than one, I secretly wish that Avent will accommodate more breast flange size, just like Medela does.
- Too gentle suction. I don’t know whether it is a separate problem or related to poorly fit breast flange that I discussed in previous point. But I seriously feel the suction is way too gentle. Perhaps this is solely my preference, but if you are used to strong suction, then do note that I would categorise this breast pump as a ‘gentle’ breast pump.
- Hands getting tired easily. I really don’t know why this happens. My hand aches faster when pumping with Avent Comfort breast pump compared to the older model.
Final thought
While I am happy that Avent Comfort manual breast pump has improved its design to minimize milk leakage and wastage under the pump cushion and diaphragm, I was disappointed with its decreased suction strength and short breast flange tunnel. Perhaps it does not fit my breast+nipple very well, thus I experience decreased suction.
As I mentioned before, this reviews may be biased due to my personal breast and nipple shape. Click here to read more reviews in Amazon.
If you are looking for breast pump which effectively remove milk from the breast, here are my two recommendations:
- Manual breast pump: Avent Isis manual
- Electric breast pump: Spectra S1
I hope this reviews help you to weigh pros and cons of Avent Comfort Manual breast pump.

I am SO excited to say that after reading your review on the isis, I was able to ding a brand new one, in fact it is the on the go set with a cooler and cold packs and extra bottles for $19 on mercari! My question is, can I replace the star valve with my spectra valve, will it fit? I am so excited to get it!
Also, I must tell you that since finding your site, I am OBSESSED with it and am on it at least once a day finding more valuable info! I am currently struggling with feeding at the breast as some well intended nurses at the hospital kind of messed it up for me giving me a shield and having me supplement ebm from day one using a bottle, so I have FINALLY weaned my 2 month old son off the shield but he still will fight and want the bottle. Your site is SO awesome and has helped me incredibly! Thank you!

Hi Emma,
I’m so glad you find the site useful. As for your question, I haven’t tried replacing star valve with Spectra valve, so I don’t know if it will fit securely.All the best to your breastfeeding journey, you can do this!
