The right breast pump depends on how often you plan to pump, where you’ll be doing it, and whether you’re pumping as a supplement to nursing or as your baby’s primary milk source. There’s no single best pump for everyone, but narrowing down a few key factors will point you toward the right type quickly.
Three Main Types of Breast Pumps
Breast pumps fall into three categories: manual, electric, and wearable. Each works differently and fits different routines.
Manual pumps use a hand lever to create suction. They’re lightweight, quiet, inexpensive, and don’t need batteries or an outlet. The tradeoff is speed: each session takes longer because you’re doing the work yourself, and most manual pumps only express from one breast at a time. These work well if you only pump occasionally, like relieving engorgement or collecting a bottle’s worth of milk before going out.
Electric pumps use a motor to generate suction and are the standard choice for regular pumping. Some plug into a wall outlet, while battery-powered versions let you pump without being tethered to one spot. Many electric pumps are double pumps, meaning they express from both breasts simultaneously, cutting your session time roughly in half. If you’re returning to work or pumping multiple times a day, an electric double pump is the most practical option.
Wearable pumps are a newer category. They tuck inside your bra, freeing your hands completely so you can pump while working, cooking, or moving around. They’re discreet enough to use in public without anyone noticing. However, wearable pumps come with an important caveat: many people find they don’t fully empty the breast. When that happens consistently, your body can interpret the leftover milk as a signal to produce less. Lactation professionals generally recommend using wearables as a convenient “on the go” option alongside a standard electric pump rather than as your only pump.
Match Your Pump to Your Routine
The FDA recommends thinking through a few practical questions before choosing. How often will you pump? Will you be near an outlet, or do you need portability? Are you pumping to supplement nursing, or is pumping your baby’s main source of milk?
If you’re home with your baby and nursing most of the time, a manual pump or a basic single electric pump handles the occasional session just fine. If you’re heading back to work, you need something faster and more portable. A battery-powered double electric pump that fits in a carrying case with your supplies is the go-to for most working parents. If you travel frequently, weight and portability matter even more, so check the pump’s weight and whether it comes with a travel bag.
Parents who are exclusively pumping (not nursing directly at the breast) need a pump with strong, consistent suction that fully empties both breasts. A standard double electric pump is typically the minimum here. Some exclusively pumping parents rent multi-user pumps, sometimes called “hospital grade,” from hospitals or specialty supply stores for their stronger motors. Worth noting: the FDA does not regulate the term “hospital grade,” so different companies can mean different things by it. What distinguishes multi-user pumps is that they’re designed to be safely shared between renters, with each person purchasing their own tubing and shields.
Suction Strength and What the Numbers Mean
Breast pump suction is measured in millimeters of mercury (mmHg). Personal-use pumps typically max out around 200 to 250 mmHg, while multi-user pumps reach into the 300 range. If you’re buying a personal pump and want solid performance, look for a maximum suction level between 250 and 300 mmHg.
Higher suction doesn’t automatically mean more milk. Pumping at too high a setting can cause pain, swelling, and even tissue damage, all of which reduce output. Most people get the best results at a moderate suction level that feels comfortable but firm. Start on a lower setting and gradually increase until you find the level where milk flows well without discomfort.
Flange Fit Makes or Breaks Your Experience
The flange (also called a breast shield) is the cone-shaped piece that sits against your breast. Getting the right size is one of the most overlooked steps in choosing a pump, and a poor fit causes pain, nipple damage, and lower milk output. Your left and right nipples can be different sizes, so you may need two different flanges.
To find your size, measure the width of each nipple tip in millimeters before pumping. Gently touch or tug the nipple so it stands out a bit, then use a ruler with millimeter markings, starting at zero from one edge of the nipple tip. The best-fitting flange is usually close to the actual diameter of your nipple. When you pump, your nipple should move freely in the tunnel without rubbing the sides, but there shouldn’t be a large gap of areola being pulled in either.
The Washington State Department of Health recommends trying two or three sizes: one slightly smaller than your measurement, one about the same, and one slightly larger. Pump on a low setting with each and see which one feels most comfortable and produces the most milk. Most pumps come with one or two standard flange sizes (often 24mm and 28mm), so you may need to order additional sizes separately.
Insurance Coverage and Cost
Under the Affordable Care Act, most health insurance plans must cover the cost of a breast pump. This applies to Marketplace plans and nearly all other plans, with the exception of older “grandfathered” plans. Your plan may cover a rental or a new pump you keep, and it may specify whether you get a manual or electric model.
Some plans require a prescription or pre-authorization from your doctor, and the timing varies. Certain insurers provide the pump before birth, while others wait until after delivery. Call your insurance company or check their online portal well before your due date to find out which pumps are covered, whether you need paperwork from your provider, and when you can receive it. Many durable medical equipment suppliers specialize in processing insurance breast pump orders and can walk you through the steps.
If your insurance covers a basic pump but you want a higher-end model, some suppliers let you pay the difference out of pocket. Manual pumps start around $20 to $40, standard electric double pumps range from $100 to $300 at retail, and wearable pumps typically run $150 to $400.
Cleaning and Maintenance
Every part that touches breast milk, including bottles, valves, flanges, and connectors, needs to be washed after each pumping session. Rinse parts in cool water as soon as you finish, then wash each piece separately with liquid dish soap and warm water. Rinse with hot water for 10 to 15 seconds per piece and let everything air dry on a clean paper towel or drying rack.
Full sterilization isn’t possible at home, but it’s also not necessary. Thorough washing with soap and water removes enough bacteria to keep parts safe for a single user. Microwave steam bags marketed as sterilizers don’t meet the technical definition of sterilization, but they do provide adequate sanitizing for personal use. They’re a convenient option if you want extra peace of mind.
Small parts like valves, membranes, and duckbill flaps wear out over time and affect suction when they do. If you notice your pump feels weaker than it used to, replacing these inexpensive parts often fixes the problem. Check your pump’s manual for replacement schedules, but a good rule of thumb is to inspect them every few weeks and replace any that look stretched, torn, or warped.
A Practical Starting Point
For most parents, the smartest approach is to get a standard double electric pump through insurance as your primary pump. Use it for scheduled sessions at home or work where you need reliable output. If you find you also need hands-free flexibility for errands or certain work situations, add a wearable pump later as a secondary option. And if you only pump once in a while, a simple manual pump tucked in your diaper bag may be all you ever need.
Whatever you choose, prioritize flange fit and suction comfort over brand names or features. The most expensive pump on the market won’t work well if the flange doesn’t fit or the suction level irritates your skin. Start with proper sizing, experiment with settings, and adjust from there.
