Quick verdict: The Munchkin Arm & Hammer Diaper Bag Dispenser is a well-executed, no-fuss solution for containing diaper odors on the go, and it earns a place in most diaper bags, with the understanding that you'll be buying refill bags regularly and that the odor control, while real, is not magic.
Diaper changes away from home have a logistics problem that wet bags and grocery bags only partially solve: the smell travels with you. Munchkin's dispenser pairs a clip-on refillable holder with bags treated with Arm & Hammer baking soda, which is a sensible combination if you already trust the brand for odor neutralization. The starter kit includes 24 bags and costs less than most specialty diaper pail refills, putting it in an accessible price range for new parents still figuring out what gear they actually need.
Munchkin® Arm and Hammer Diaper Bag Dispenser and 24 Diaper Disposal Bags
Compact odor-control bags with a clip-on dispenser that earns its spot in any diaper bag.
Check Price on AmazonWho this is for
This dispenser is best suited to parents who spend real time out of the house, at daycare drop-offs, parks, restaurants, or anywhere a garbage can isn't immediately available after a change. It's also a practical buy for caregivers who use a dedicated diaper station at home but want a portable odor management system that clips onto the bag and stays there. Budget-conscious parents will appreciate that the entry cost is low, though the ongoing refill cost requires attention. It's less useful for exclusively home-bound caregivers who already have a dedicated pail with sealing mechanism.
What we like
- Clip-on dispenser design. The dispenser attaches directly to a diaper bag strap or stroller, so you're not fishing through a bag interior to find it during a change. It stays accessible without taking up internal pocket space.
- Arm & Hammer baking soda treatment. The bags carry a measurable advantage over plain plastic bags: the baking soda formulation does absorb a portion of the odor rather than simply sealing it. This is not the same as a vacuum seal, but it makes a meaningful difference when you're carrying a used diaper for more than a few minutes.
- Bag thickness and seal. The disposal bags tie shut and are thick enough that they don't puncture easily when knotted. Thin produce-bag-style competitors fail here regularly, and these don't.
- Low entry price. The dispenser itself is bundled with 24 bags at a price point that makes it a viable addition to a new baby registry or a practical gift basket without requiring a financial commitment to a full diaper pail system.
- Refill compatibility. Munchkin sells refill rolls separately, and the dispenser is designed to accept them without modification. This matters more than it sounds, some competing systems use proprietary cartridges that can become unavailable.
What we don't like
- 24 bags disappear fast. A newborn produces eight to twelve diapers a day. At that rate, 24 bags last roughly two to three days if you're using one per change. The starter kit is not a stockpile, it's a trial, and parents who don't order refills before running out will find themselves back to grocery store bags within the first week.
- Odor control has a time limit. The baking soda treatment works as a buffer, not a barrier. A tied bag sitting in a warm car or a closed stroller basket for more than 30 to 45 minutes will start to assert itself. This product manages odor during the immediate window around a change; it does not eliminate odor across an entire afternoon outing if you're not disposing of bags regularly.
- Dispenser clip is lightweight plastic. The clip secures to thin strap webbing well, but on thick padded straps or handles, it sits at an angle and can work loose. It's not prone to snapping, but it does not feel like hardware that will survive years of daily use without eventually loosening.
How it compares
The most direct competitors in this space are the Dekor Plus Diaper Pail refill bags used portablythe Ubbi On-the-Go Diaper Bagand basic scented disposal bags from brands like Playtex. The Dekor bags are not designed for portable use and lack a clip system, making them a worse choice for diaper-bag attachment despite comparable odor control. The Ubbi bag is a reusable wet bag with no baking soda treatment, it's washable and eco-friendlier, but it requires laundering between uses and brings the odor home with it every time. Scented alternatives from Playtex and generic brands mask rather than neutralize, which is a real difference if you're sensitive to fragrance mixing with diaper smell in an enclosed space. The Munchkin Arm & Hammer dispenser wins on the combination of clip-on convenience, genuine baking soda neutralization, and refill availability. The case for skipping it is primarily environmental: if you're already committed to a reusable wet bag system for outings, the additional plastic waste here is not trivial.
The verdict
For most parents managing diaper changes away from home, this dispenser solves a real problem at a fair price. The Arm & Hammer formulation is a legitimate upgrade over plain plastic or lightly scented alternatives, and the clip system is practical enough to stay attached to a bag rather than getting buried in it. The reservations are real: refill consumption is high in the newborn stage, odor control is time-limited rather than absolute, and the clip hardware is not built for the long haul. But as part of a broader on-the-go kit, alongside a reliable pack of wipes and a portable changing setup, it pulls its weight. Buy the dispenser, immediately order a second roll of refill bags, and set a reminder to reorder before you run out.

Frequently asked questions
How many bags come in a refill roll?
Munchkin's refill rolls typically contain 72 bags per pack, available as a single roll or multi-pack. Given the daily volume of diaper changes in the infant stage, a multi-pack purchase makes more sense economically than buying single rolls.
Are these bags biodegradable or compostable?
No. These are standard plastic bags with a baking soda additive. They are not marketed as biodegradable or compostable, which is a genuine consideration if reducing single-use plastic is a household priority.
Can the dispenser be used with other brand bags?
The dispenser is designed for Munchkin's own refill rolls, but because the bags are on a standard roll format, other thin-roll disposal bags can be loaded in as well. Compatibility varies by bag thickness, and very thick rolls may not sit flush inside the dispenser housing.
Does the baking soda treatment affect babies with sensitive skin?
The baking soda is in the bag material, not in contact with skin during normal use. The bags are used for disposal only, not as a liner against skin. Skin contact with the bag itself during a change is incidental and brief.
Is this a substitute for a dedicated diaper pail at home?
No, and it's not designed to be. For home use, a sealed pail system like the Dekor Plus or Ubbi provides better odor containment over multiple diapers across a day. This dispenser is purpose-built for portable, single-use disposal during outings. If you're building out a complete nursery system, pair it with a proper pail at home and use the right surface protection at your changing station.
