Key takeaways
- Manual pumps: the Medela Harmony weighs 105 g and ships with one size M PersonalFit Flex shield and a 150 ml bottle [2]. The Lansinoh Manual ships with 25 mm and 30.5 mm flanges and a 5 oz bottle [1].
- Both hand pumps use two phases. Medela does it with the short and long side of the handle, and Lansinoh by moving the handle on the stem [1][2].
- Electric pumps: the Signature Pro lists 8 levels, a closed system, and AA battery power [3]. The Pump In Style Pro lists 16 levels, 1.23 lb, and AC power only [4].
- Suction numbers come from a supplier, not the makers' own pages: Aeroflow lists 250 mmHg for the Signature Pro and 295 mmHg for the Pump In Style Pro [5][6].
- Coverage is plan by plan. Aeroflow's Lansinoh and Medela pages describe the pumps as partially covered with a small co-pay or deductible, and says secondary insurance may cover the rest [5][6].

Lansinoh and Medela each sell a hand pump and a plug-in double electric pump, and parents shopping for one often end up comparing the other. The Medela Harmony weighs 105 grams and has a soft-rim shield [2]. The Lansinoh Manual comes with two flange sizes [1]. This guide lines up both hand pumps, then the Lansinoh Signature Pro against the Medela Pump In Style Pro, using what the makers and suppliers publish.
Lansinoh vs Medela manual pumps side by side

Which manual pump fits which situation
| If you... | Look at | Why |
|---|---|---|
| Want the lightest option on paper | Medela Harmony | 105 g, and Lansinoh publishes no weight [1][2] |
| Already own Lansinoh bottles | Lansinoh Manual | Its bottle fits Lansinoh's wide-neck range [1] |
| Aren't sure of your flange size | Either, with a measurement | Lansinoh ships two sizes, and Medela ships one size M shield [1][2] |
| Pump several times a day | A double electric instead | Medela says frequent pumpers may prefer one [2] |
Flange fit matters more than the brand. See our flange size guide before you assume the box size works. A lactation consultant can check fit in person.

What the numbers do and don't tell you
Suction numbers here come from Aeroflow, not from either maker's page, and they're ceilings, not promises. Medela's page lists 16 levels and points to the instructions for the vacuum range [4]. Lansinoh lists 8 levels [3].
Two real differences stand out. The Signature Pro can run without an outlet on AA batteries, and the Pump In Style Pro can't [3][4]. The Pump In Style Pro is a known weight at 1.23 lb, while Lansinoh doesn't publish one [3][4]. If you want a rechargeable Medela, that's the Pump In Style Pro+, covered in our Spectra vs Medela guide.
Does insurance cover Lansinoh or Medela pumps?
Federal rules require non-grandfathered plans to cover breastfeeding equipment, but the plan and its supplier decide which pump and what you pay [8]. Byram says most plans cover a set value of pump as "fully covered," and the upgrade fee is the gap between that amount and the pump's price [7]. That fee isn't reimbursable by insurance but may be payable with HSA or FSA money [7].
What suppliers say:
- Medela Pump In Style Pro. Byram lists it among its traditional primary pumps for 2026 [7]. Aeroflow's Medela page describes its pumps as partially covered with a small co-pay or deductible [6].
- Lansinoh Signature Pro. Aeroflow's Lansinoh page uses the same partial-coverage note, and adds that secondary insurance may cover more [5].
- Manual pumps. Byram says TRICARE covers one manual or standard electric pump per birth event at no cost [7]. Aeroflow carries the Harmony [6]. We found no supplier statement about the Lansinoh Manual, so ask.
Those notes are generic and don't state a dollar fee. Our guide on ordering a pump through insurance covers the steps, and the 12-model coverage comparison shows how pumps sort into covered and upgrade tiers. For wearables, see wearable pumps compared.
Recalls and safety
We searched FDA's device recall database on October 16, 2026 [9]. For Lansinoh we found no pump entries, only a 2012 recall of its hot and cold breast therapy pack. For Medela we found 2010 and 2011 records for older accessory kits, the Pump in Style Advanced family and its power adapter. We found nothing for the Harmony or the current Pump In Style Pro. Recalls can be added at any time, so check the maker's site for your exact model.
Where to buy
If you're paying out of pocket, here are the labeled Amazon links: Lansinoh Manual Affiliate link, Medela Harmony Affiliate link, Lansinoh Signature Pro Affiliate link and Medela Pump In Style Pro Affiliate link. Check price on Amazon, but ask your supplier first, since a covered pump usually costs less that way. For more models, see breast pumps compared.
Questions people ask
Is the Lansinoh or Medela manual breast pump better?
We can't rank them, but the published facts differ. Medela's Harmony weighs 105 g, includes a 150 ml bottle and a soft-rim PersonalFit Flex shield in size M. Lansinoh's Manual includes 25 mm and 30.5 mm flanges and a 5 oz bottle. Check which flange size fits you, because a poor fit changes comfort more than any other spec.
Do Lansinoh and Medela manual pumps use the same bottles?
No. Lansinoh says its manual pump is designed for Lansinoh bottles and won't fit other brands, though it can pump directly into Lansinoh storage bags. The Harmony includes its own 150 ml bottle with a lid and a stand.
Is the Lansinoh Signature Pro as strong as the Medela Pump In Style?
Neither maker's page lists a maximum suction. Aeroflow lists 250 mmHg for the Signature Pro and 295 mmHg for the Pump In Style Pro, but a higher ceiling doesn't promise more milk. Flange fit, session length and your own supply matter more.
Can I run the Lansinoh Signature Pro or Medela Pump In Style without an outlet?
The Signature Pro can run on 6 AA batteries, which aren't included, or a car adapter sold separately. The Pump In Style Pro uses an AC power adapter. Medela's battery model is the Pump In Style Pro+, a different pump.
Will insurance cover a Lansinoh or Medela breast pump?
Non-grandfathered plans must cover breastfeeding equipment, but your plan and supplier choose the model and what you pay. Byram lists the Medela Pump In Style Pro among its traditional primary pumps. Aeroflow marks both brands' pumps as partially covered with a small co-pay or deductible.
Have Lansinoh or Medela pumps been recalled?
We searched FDA's device recall database on October 16, 2026. We found no entries for Lansinoh pumps, only a 2012 Lansinoh hot and cold breast therapy pack. For Medela we found only 2010 and 2011 records for older kits and the Pump in Style Advanced family, not the current Pro. Recalls can be added at any time, so check each maker's site.
