What is the best diaper pail for odor control?

If odor control is your #1 priority, I’d go with the Munchkin STEP Diaper Pail.

• Munchkin STEP Diaper Pail - $74.99 (Munchkin)

BabyGearLab’s testing of nine diaper pails gave the STEP its highest odor-control rating. Its self-sealing system twists the liner closed around each diaper, and an Arm & Hammer baking-soda puck adds another odor-control layer.BabyGearLab

How I’d choose

• 🥇 Maximum odor control: Munchkin STEP — strongest independent testing for containing smells. The downside is proprietary refills and a noticeable fragrance from the baking-soda puck.BabyGearLab

• 💰 Avoid expensive refills: Ubbi Steel — uses ordinary 13-gallon trash bags and has a sealed steel body. However, interestingly, BabyGearLab's testing found it retained odors more than expected, so I wouldn't pick it specifically for maximum odor control.BabyGearLab

• 🦶 Hands-free + strong odor control: Diaper Genie Platinum — stainless steel, foot pedal, and odor-locking clamps.Good Housekeeping

• Munchkin STEP - $74.99 (Munchkin)

• Diaper Genie Platinum - $75.00 (Walmart)

• Ubbi Steel - $69.99 (Walmart)

Bottom line: If you have a newborn now but especially want something that won't stink once they start eating solid food, I'd choose the Munchkin STEP. The refill cost is the main tradeoff.

If you tell me your budget (e.g. under $50, $75, or “money no object”), I can narrow it down to the best 2–3 options.

If odor control is your #1 priority, I’d go with the Munchkin STEP. Independent testing gave it a 10/10 for odor control, with its self-sealing liner keeping each diaper’s smell contained.BabyGearLab+1

• Munchkin STEP Diaper Pail - $74.99 (Munchkin)

How I’d choose

• 🥇 Maximum odor control: Munchkin STEP — The bag twists/seals as you use it, so opening the lid doesn't expose a column of dirty diapers. The main downside is ongoing proprietary-refill cost and the scented baking-soda puck.BabyGearLab

• 🥈 Best if you hate proprietary bags: Ubbi Steel — Steel construction, rubber seals and a sliding lid do a very good job containing odor, while letting you use ordinary kitchen trash bags. Babylist's 2026 testing/research picked it as its top overall pail.Babylist

• 🥉 Good hands-free alternative: Diaper Dekor EKO/Plus — Foot-pedal operation and continuous liners; odor control is good, though testing generally puts it behind Munchkin for maximum odor containment.

• Munchkin STEP - $74.99 (Munchkin)

• Ubbi Stainless Steel - $69.99 (Target)

• Diaper Dekor EKO Plus - $64.99 (Target)

• Diaper Genie Platinum - $75.00 (Walmart)

Bottom line: If you want the least smell possible, choose Munchkin STEP. If you want excellent odor control without being locked into special bags, choose Ubbi.

If odor control is your #1 priority, the two diaper pails that consistently rise to the top are:

Quick recommendation

• Maximum stink protection: Munchkin STEPBabyGearLab
• Best balance of odor control + low ongoing cost: UbbiForbes
• Best if you want a foot pedal: Munchkin STEP or Diaper Genie PlatinumMunchkin

For most nurseries, I’d pick Munchkin STEP if odor is the only thing you care about, and Ubbi if you want a pail you’ll still love after months of buying refills.

When it comes to keeping nursery odors under control, two distinct champions dominate parent reviews and expert testing: one that uses a specialized sealing system, and one that saves you money by using standard trash bags.nytimes.com+1[2]

The top options for odor control break down as follows:

Add to listMunchkin Step Diaper Pail — Best for Maximum Odor Sealing

• How it works: It uses a patented self-sealing system that twists/shuts the bag closed every time you close the lid, meaning you never get that dreaded "stinky blast" of trapped air when you open it back up . It is also partnered with Arm & Hammer and features a lavender-scented baking soda puck in the lid to actively absorb lingering smells.
• Pros: Exceptional odor-locking capability; hands-free foot pedal.
• Cons: Requires specialized refill rings/bags.[1]

Add to listUbbi Steel Diaper Pail — Best Value & Eco-Friendly (No Special Bags Needed)

• How it works: Made of powder-coated steel rather than plastic, it doesn’t absorb odors over time. It features rubber seals for an airtight lock and a sliding lid that minimizes air disruption when opening.
• Pros: Works with any standard kitchen trash bag (saving you a significant amount on refill subscriptions), highly durable, and comes in many aesthetic colors.
• Cons: Opening the sliding lid manually lets out a small puff of air compared to self-sealing models, though the rubber gaskets do a heavy-duty job containing the rest.[1]

Add to listDiaper Genie Platinum Pail — Best Upgraded Classic

• How it works: The stainless-steel Platinum version upgrades the classic Diaper Genie design with odor-locking clamps and a carbon filter to trap heavy solid-food diaper odors.
• Pros: Excellent clamp mechanism that suffocates smells; durable stainless steel body prevents odor absorption.
• Cons: Proprietary refills required; emptying requires cutting/knotting the plastic film.youtube.com+1

If you want to narrow this down, let me know:

• Are you hoping to use regular trash bags or do you mind specialty refills?
• What is your budget for the pail itself?

If odor control is your top priority, the strongest overall choice is:

• Munchkin STEP Diaper Pail - $74.99 (Munchkin)

Independent testing consistently ranks the Munchkin STEP at or near the top for containing smells. Its self-sealing system helps prevent odor from escaping even while you're adding a diaper, and it uses an Arm & Hammer baking soda puck for additional odor absorption.BabyGearLab+1

Here are the best options depending on what matters most:

• Diaper Genie Platinum - $75.00 (Walmart)

A great choice if you want:

• Excellent odor control
• Hands-free foot pedal
• Stainless steel construction
• Carbon filter and odor-locking clamps

Trade-off: It requires proprietary refill bags, which increase ongoing costs.Good Housekeeping+1

• Ubbi Stainless Steel Diaper Pail - $69.99 (Target)

A great choice if you want:

• To use standard kitchen trash bags
• No proprietary refills
• Durable steel construction

The Ubbi has many loyal fans and is frequently recommended, but independent odor-control testing has been mixed. Some reviewers rate it as excellent, while others found it retained odors over long-term use more than expected.Babylist+1

Quick comparison

My recommendation

For most families, I'd choose the Munchkin STEP because it combines the strongest independent odor-control performance with solid usability. If you don't mind buying refill bags, it's difficult to beat for keeping the nursery smelling fresh. If you'd rather avoid proprietary bags and save money over the long run, the Ubbi is still an excellent alternative despite the mixed long-term testing results.

If odor control is your #1 priority, I’d pick the Ubbi Steel Diaper Pail.

• Ubbi Stainless Steel Diaper Pail - $69.99 (Walmart)

Why the Ubbi is my top pick

• Steel construction is excellent at containing smells rather than absorbing them like some plastic pails.
• Rubber seals + sliding lid create a tight odor barrier.
• No proprietary bags required — you can use ordinary kitchen/trash bags, which can save money over years of diapering.
• It has a childproof lock, useful once your baby becomes mobile.
• Current pricing is around $70, depending on retailer/color.

Other excellent choices

• Munchkin STEP Diaper Pail - $74.99 (Munchkin)
• Diaper Genie Platinum Pail - $75.00 (Walmart)
• Munchkin PAIL Diaper Pail - $39.97 (Walmart)
• Diaper Genie Classic Pail - $27.99 (Target)

My ranking for odor control:

1. 🥇 Ubbi Steel — best overall odor containment + no proprietary bags
2. 🥈 Munchkin STEP — excellent odor control, self-sealing system, plus Arm & Hammer baking-soda odor absorption
3. 🥉 Diaper Genie Platinum — very strong odor-locking system and stainless-steel construction
4. Diaper Genie Classic — best inexpensive option if you want good odor control without spending ~$70+

Bottom line: If you want the least smell possible and don't mind paying a little more upfront, get the Ubbi. If you want hands-free foot-pedal operation, I'd choose the Munchkin STEP instead.
