Choosing a breast pump is one of the most important gear decisions a breastfeeding parent will make. The right pump supports your milk supply, fits your lifestyle, and makes the pumping experience as comfortable as possible. For storage tips, see our pumping and storing breast milk guide. The wrong pump can lead to pain, reduced output, and unnecessary frustration.
This guide walks you through every type of breast pump available, explains how insurance coverage works, helps you find the correct flange size, and covers the accessories that make pumping easier. You may also want to review our breastfeeding basics guide if you are just getting started.
Types of Breast Pumps
Manual Breast Pumps
Manual pumps use a hand-operated lever or squeeze mechanism to create suction. They have no motor, no batteries, and no cords.
Pros:
- Lightweight and highly portable
- Silent operation
- No charging or power source needed
- Affordable ($15-$40)
- Easy to clean with fewer parts
Cons:
- Requires hand effort, which can cause fatigue
- Slower output compared to electric pumps
- Only expresses one breast at a time
- Not ideal for exclusive pumping
Best for: Occasional pumping, travel, relieving engorgement, or as a backup pump.
Single Electric Breast Pumps
Single electric pumps use a motor to create suction on one breast at a time. They are a step up from manual pumps in terms of efficiency.
Pros:
- Less hand fatigue than manual pumps
- More affordable than double electric
- Compact and portable
- Good for occasional to moderate pumping
Cons:
- Pumping takes twice as long as double electric
- May not maintain supply as effectively for exclusive pumpers
- Still requires you to hold the flange in place
Best for: Parents who pump occasionally or supplement breastfeeding with pumped bottles.
Double Electric Breast Pumps
Double electric pumps express milk from both breasts simultaneously. They are the standard recommendation for parents who pump regularly.
Pros:
- Cuts pumping time in half
- Better at maintaining and increasing milk supply
- Often covered by insurance
- Multiple suction and speed settings
- Some models are portable with rechargeable batteries
Cons:
- More expensive ($100-$350)
- More parts to clean
- Motor noise (varies by model)
- Requires both hands or a hands-free bra
Best for: Working parents, exclusive pumpers, and anyone who pumps more than once or twice daily.
Hospital-Grade Rental Pumps
Hospital-grade pumps are the most powerful breast pumps available. They feature stronger motors with more consistent suction patterns designed to closely mimic a baby’s natural nursing rhythm. These pumps are designed for multi-user use with individual accessory kits.
Pros:
- Most effective at establishing and maintaining supply
- Ideal for premature babies or NICU situations
- Designed for heavy daily use
- Typically quieter than personal-use pumps
Cons:
- Expensive to purchase ($1,000-$2,500), so rental is standard
- Rental costs $50-$100 per month
- Large and heavy, not portable
- Requires separate accessory kit purchase
Best for: Parents with premature infants, those struggling with low supply, early weeks of establishing breastfeeding, or exclusive pumpers who need maximum efficiency.
Wearable Breast Pumps
Wearable pumps fit entirely inside your bra with no external tubes or bottles. They have become increasingly popular as technology has improved, allowing parents to pump discreetly while going about their daily activities.
Pros:
- Completely hands-free
- Discreet under clothing
- Allows pumping while multitasking
- Cordless and portable
- Controlled via smartphone app (most models)
Cons:
- Lower suction power than traditional electric pumps
- Smaller milk collection capacity (typically 4-5 oz per side)
- Can be tricky to position correctly
- Higher price point ($200-$500)
- May not be sufficient for exclusive pumping as a sole pump
Best for: Working parents who need to pump during meetings, parents caring for older children, anyone who values discretion and mobility.
Insurance Coverage for Breast Pumps
The ACA Mandate
Under the Affordable Care Act (ACA), most health insurance plans are required to cover the cost of a breast pump. This coverage typically includes:
- A new breast pump for each pregnancy
- Either a manual or electric pump (plan dependent)
- Rental of a hospital-grade pump when medically necessary
- Lactation support and counseling
How to Get Your Pump Through Insurance
- Call your insurance company at least 4-6 weeks before your due date. Ask specifically what breast pump brands and models are covered.
- Get a prescription from your OB-GYN or midwife. Most insurers require a prescription or letter of medical necessity.
- Choose a durable medical equipment (DME) supplier that is in-network with your plan. Many online DME suppliers specialize in breast pumps and handle the insurance paperwork for you.
- Understand your options. Some plans offer a specific pump model at no cost, while others provide a dollar amount that you can apply toward any pump.
- Check timing. Some plans allow you to receive the pump before delivery, while others require you to wait until after birth.
If Your Insurance Does Not Cover a Pump
If you have a grandfathered plan or a plan that is exempt from ACA requirements, you still have options:
- WIC (Women, Infants, and Children) programs often provide or loan breast pumps
- Many hospitals have pump rental programs
- Some nonprofit organizations provide pumps to families in need
- Budget-friendly manual pumps start around $15
Key Features to Compare
Suction Levels
Look for a pump with adjustable suction strength. Most quality pumps offer 8 to 12 suction levels. Higher suction does not always mean more milk — the most effective suction level varies by individual and can change over time. Starting low and gradually increasing until you find your comfort zone is recommended.
Cycle Speed (Expression Modes)
Quality breast pumps offer at least two modes:
- Stimulation mode (letdown mode): Rapid, lighter suction that mimics a baby’s initial quick sucking to trigger the letdown reflex. Typically 100-120 cycles per minute.
- Expression mode: Slower, deeper suction that draws milk out efficiently. Typically 50-70 cycles per minute.
Some advanced pumps automatically switch from stimulation to expression mode when they detect letdown.
Flange Sizing
The flange (also called a breast shield) is the cone-shaped piece that fits over your nipple. Correct flange size is critical for comfort and output.
Signs your flange is too small:
- Nipple rubs against the sides of the tunnel
- Pain during pumping
- White spots on the nipple after pumping
- Reduced output over time
Signs your flange is too large:
- Too much areola is pulled into the tunnel
- Nipple moves freely without friction (too much space)
- Less efficient milk removal
Standard flange sizes:
| Nipple Diameter (mm) | Recommended Flange Size (mm) |
|---|---|
| Less than 17 | 21 |
| 17-19 | 24 |
| 20-22 | 27 |
| 23-25 | 30 |
| 26+ | 33-36 |
To measure your nipple diameter, use a ruler or printable sizing tool after nursing or pumping when the nipple is at its widest. Measure only the nipple, not the areola. Many lactation consultants can help with sizing during a consultation.
Portability
If you will pump away from home, consider:
- Battery life: Look for at least 2-3 hours of battery per charge for electric pumps
- Weight: Portable pumps range from 0.5 lbs (wearable) to 2.5 lbs (double electric)
- Charging method: USB-C charging is the most convenient; some pumps still use proprietary chargers
Noise Level
Pump noise ranges from nearly silent (wearable pumps, around 35-40 dB) to noticeable (some older electric models, 55-65 dB). For reference, a whisper is about 30 dB and normal conversation is about 60 dB. If you plan to pump during meetings, on phone calls, or while your baby sleeps, noise level should be a priority.
Flange Fitting Guide
Getting the right flange fit can make a dramatic difference in comfort and output. Follow this step-by-step process:
- Measure your nipple diameter at the base (where it meets the areola) after a feeding or pumping session. Nipples swell during pumping, so measuring beforehand can give an inaccurate result.
- Add 1-2 mm to your measurement to find your starting flange size.
- Test the fit. Your nipple should move freely in the flange tunnel without rubbing the sides. A small amount of areola may be drawn in, but the majority should remain outside.
- Observe during pumping. Milk should flow steadily. If output drops or you experience pain, try a different size.
- Re-measure periodically. Nipple size can change over the course of your breastfeeding journey, especially in the first few weeks.
Many brands now offer silicone flange inserts that allow you to customize the fit of a standard flange. These inserts are an affordable way to fine-tune sizing without buying multiple flanges.
Essential Pumping Accessories
Hands-Free Pumping Bra
A hands-free pumping bra holds the flanges in place so you can type, eat, or hold your baby while pumping. Options include dedicated pumping bras, clip-on bustier-style bras that go over your nursing bra, and DIY solutions using a sports bra with small holes cut for the flanges.
Breast Milk Storage Bags
Pre-sterilized, sealable bags designed for breast milk storage are essential for building a freezer stash. Look for bags that:
- Are BPA-free
- Have a double-seal closure
- Include a write-on label area for date and volume
- Stand upright for easy filling
- Lay flat for efficient freezer storage
Cooler Bag with Ice Packs
If you pump at work or on the go, a small insulated cooler bag with ice packs keeps expressed milk safe for up to 24 hours. Some diaper bags include a built-in insulated compartment that serves this purpose.
Additional Helpful Accessories
- Extra sets of pump parts — so you can rotate between uses and reduce washing frequency
- Pump part micro-steam bags — for quick microwave sterilization
- Nipple cream or coconut oil — to reduce friction and soreness
- Pump wipes — for quick cleaning between sessions when a sink is not available
- Car adapter — if your pump supports one, for pumping during commutes (as a passenger)
Cleaning and Sterilizing Pump Parts
Proper cleaning of pump parts is essential to keep expressed milk safe for your baby.
After Every Use
- Disassemble all parts that contact breast milk.
- Rinse parts immediately under running water to remove milk residue.
- Wash in hot soapy water using a dedicated bottle brush. Do not use the kitchen sponge, which can harbor bacteria.
- Rinse thoroughly and air dry on a clean drying rack or paper towel.
Daily Sterilization (Recommended for Babies Under 3 Months)
The CDC recommends sanitizing pump parts at least once daily for babies younger than 3 months, premature infants, or immunocompromised babies. Sterilization methods include:
- Boiling: Submerge parts in boiling water for 5 minutes.
- Steam sterilizer bags: Place parts in a microwave steam bag per manufacturer instructions (typically 3 minutes).
- Electric steam sterilizer: Follow the device instructions.
- Dishwasher: If parts are dishwasher-safe, use the hot water and heated drying cycle.
The Refrigerator Hack
Some parents place used pump parts in a sealed bag in the refrigerator between sessions and wash thoroughly once at the end of the day. While this method is widely practiced, the CDC does not officially endorse it. If your baby is a newborn, premature, or has a compromised immune system, washing after every use is the safer choice.
Top Picks by Category
Best Overall Double Electric
Look for a closed-system double electric pump with a rechargeable battery, hospital-strength suction, and a compact design. The best options in this category offer 10+ suction levels, both stimulation and expression modes, and weigh under 2 pounds with the battery.
Best Wearable Pump
The ideal wearable pump offers suction comparable to a traditional electric pump in a low-profile design that fits inside a standard bra. Prioritize models with at least 5 oz collection capacity per side, app-based control, and a battery that lasts 4+ sessions per charge.
Best Manual Pump
A quality manual pump should have an ergonomic handle that does not cause hand fatigue, a soft silicone cushion on the flange, and the ability to create strong suction with minimal effort. Two-phase manual pumps that offer both stimulation and expression modes are the most effective.
Best Hospital-Grade Rental
If you need a hospital-grade pump, contact your hospital’s lactation department or a local DME supplier. Many insurance plans cover rental costs with a prescription. Ensure the rental comes with a new, sealed accessory kit for hygiene purposes.
Best Budget Option
Effective breast pumps exist at every price point. For parents on a tight budget, insurance-covered options are the first choice. Beyond that, quality manual pumps in the $20-$35 range perform well for occasional use, and basic double electric pumps under $80 can serve moderate pumping needs.
Frequently Asked Questions
How often should I replace breast pump parts?
Replace duck valves and membranes every 1-2 months or sooner if they appear stretched, cracked, or discolored. Backflow protectors should be replaced every 3-6 months. Flanges and bottles can last the entire breastfeeding journey if they remain undamaged. Tubing should be replaced if moisture or mold appears inside.
Can I use a secondhand breast pump?
The FDA classifies breast pumps as single-user devices. Open-system pumps (where milk can enter the tubing and motor) should never be shared or purchased secondhand due to contamination risk. Closed-system pumps with a barrier that prevents milk from reaching the motor are lower risk with new accessory kits, but manufacturers still recommend against sharing. Hospital-grade pumps are the exception — they are specifically designed for multi-user use with individual accessory kits.
How do I know if my pump is working properly?
Signs of a well-functioning pump include consistent suction rhythm, no unusual motor sounds, intact valves and membranes that create a proper seal, and steady milk output. If you notice a decrease in suction strength, check all parts for wear before assuming a supply issue.
Does insurance cover wearable breast pumps?
Many insurance plans now include wearable pumps in their covered options, though you may need to pay the difference between the insurance allowance and the retail price of the wearable pump. Contact your insurer or DME supplier to confirm which specific models are covered.
How long does a pumping session take?
A typical double-pumping session takes 15-20 minutes. Single pumping takes 20-30 minutes per side. If you are consistently pumping for longer than 30 minutes without adequate output, consult a lactation consultant to check flange fit and pump function.
