You have already decided that cold therapy belongs in your recovery plan. The decision now is between the NICE1 and a DonJoy IceMan unit, and this comparison gives you what you need to make that call before your surgery date.
The NICE1 and the DonJoy IceMan are both FDA Class II motorized cold therapy devices with anatomical pads, so the choice does not come down to legitimacy. It comes down to how each device makes cold, whether you can select and hold a specific temperature, whether compression is included, and how you get one. Those questions decide which device serves you better through the weeks that matter most.
How to Decide Between Them
The five questions a post-surgical patient should weigh before choosing a cold therapy device.
DonJoy is a brand of Enovis, formerly DJO, and the IceMan line is sold through the Enovis and DonJoy Store websites as well as third-party medical retailers. Two units carry the IceMan name. The IceMan CLASSIC3 uses an opaque 8-quart cooler, and the IceMan CLEAR3 uses a translucent cooler so you can see the ice level without opening the lid. Both use the same dual-pump recirculation design, both require you to add ice and cold water before every session, and neither includes compression. Choosing between them is mostly a question of whether you want to see the ice supply.
Can you select a temperature, or only add more ice?
This is the difference that shows up at hour four. The NICE1 has five fixed cold settings. Level 1 holds 58°F, Level 2 holds 54°F, Level 3 holds 50°F, Level 4 holds 46°F, and Level 5 holds 42°F, the coldest. You select a level and the device holds that exact temperature for the entire session without drifting. Your care team can choose a milder setting such as Level 1 in the acute phase and a colder setting such as Level 5 for deeper-tissue work later in rehab, and each setting stays steady from the first minute to the last.
The IceMan works differently. Its recirculation system blends returning water with the ice water in the reservoir, and DonJoy states that this delivers water into the pad in a 38°F to 42°F range. There is no dial, no level, and no set point you choose. The only variable you control is how much ice you put in. DonJoy's own patient FAQ makes that explicit, advising anyone who feels the pad is not cold enough to check that the unit has been filled with enough ice. As that ice melts across a session, the reservoir warms, and the therapy warms with it.
Can it run overnight without a refill?
The acute phase, roughly days one through seven, is when swelling and pain are highest and when consistent cold has its most direct effect. The NICE1 runs through the night uninterrupted because it makes its own cold electrically. Enovis does not publish a runtime figure for the IceMan, and medical retailers commonly list roughly 6 to 7 hours per fill for the CLASSIC3 and 4 to 6 hours for the CLEAR3. Continuous overnight coverage on either unit means a mid-night refill, a caregiver waking to do it, or a gap in therapy during the hours uninterrupted cooling matters most. For shoulder patients whose pain peaks overnight, that gap is not minor. The same is true through the early weeks of knee replacement recovery, where overnight swelling control feeds directly into next-morning range of motion.
Cold only, or cold plus compression?
Combining cold with active compression has solid clinical support. A randomized trial after total knee arthroplasty found that adding compression to cryotherapy reduced swelling faster, improved knee flexion, and produced better functional recovery than cold alone. The NICE1 delivers programmable pneumatic compression in the 13 to 39 mmHg range on every rental, with on and off cycle timing adjustable by the minute so the protocol can shift as you move from acute swelling to active rehab. No IceMan unit includes compression at any tier. If your surgeon's protocol calls for cold and compression together, an IceMan means adding a separate compression solution or going without.
Are you buying a device or covering a recovery window?
The IceMan is sold as a purchase. You buy the unit and the pad, and both stay yours after recovery ends. The NICE1 is available as a rental sized to the recovery period, which for most post-surgical patients is a four to eight week window of concentrated use. Renting matches the cost to the weeks you actually need the device rather than to an asset that sits in a closet afterward. If you are weighing machines for a knee procedure specifically, our guide to the best ice machines for knee surgery recovery walks through how rental systems compare on total cost.
What does the routine look like at home?
An IceMan session starts with ice. You fill the reservoir to the line, add cold water to the line, latch the lid, connect the hose to the pad, and plug the unit in. DonJoy suggests freezing water in cups or containers to make larger ice blocks that melt more slowly, and specifically advises against dropping in labeled water bottles, since the plastic blocks heat transfer and label residue can break down into the water. After a session the cooler is drained, wiped, and air dried to prevent mold. The NICE1 asks for about one cup of water per session and a wipe-down afterward, with no ice to buy and no reservoir to sanitize.

Why the NICE1 Is the Home Recovery Standard
What changes when the cold holds steady and the device tends itself.
Your body already knows how to heal. The job of a recovery device is to stack the deck in its favor by keeping inflammation in a therapeutic range around the clock, without asking you to manage ice in the middle of the night. That is the standard the NICE1 was built to meet, and it is why orthopedic surgeons specify it for at-home recovery.
The IceMan has been a fixture in clinics and hospitals for more than twenty years, in settings where staff handle the ice and the maintenance. At home, that handling falls to you or a caregiver. Five features account for most of the difference patients notice once they are recovering on their own.
"For post-surgery recovery, I can't recommend NICE enough."
Dr. Tom Hackett, Orthopedic Surgeon and Partner, The Steadman Clinic
Five Fixed Cold Settings, Held All Session
The same therapeutic temperature at hour one and at hour six.
The NICE1 holds your selected setting for the full session, from 58°F at Level 1 down to 42°F at Level 5, the coldest. No ice, no drift, no refills. Your care team can dial a milder setting in the acute phase and a colder one for deeper-tissue work later in rehab, and the device holds whichever level you choose. On an IceMan there is no level to choose, and the amount of ice in the reservoir is what determines the therapy you get.
Programmable Compression on Every Rental
Cold and compression together, adjustable by the minute.
No IceMan unit includes compression. The NICE1 delivers programmable cold and compression from 13 to 39 mmHg on every rental, with cycle timing you can adjust by the minute. Tissue in week one of ACL recovery needs different compression intervals than tissue in month three of a throwing program, and that adjustability is built into the rental rather than sold as a separate device.
Designed for Overnight Use Without Interruption
Runs through the night with no caregiver involvement.
At 9 lbs and 8 inches cubed, the NICE1 fits on a nightstand and needs no tending once it is running. Patients and caregivers consistently name uninterrupted sleep as the largest quality-of-life gain over ice-based systems in the first two weeks, when a unit running on an ice reservoir would otherwise need a refill partway through the night.
No Daily Ice Runs, No Reservoir to Drain
The maintenance routine that quietly erodes protocol compliance.
An IceMan needs fresh ice before every session and a drain, wipe, and air dry afterward to prevent mold in the cooler. The NICE1 asks only for about a cup of water at setup and a wipe-down after use. For a caregiver managing a family member's recovery, taking the ice and maintenance routine off the daily schedule has a direct effect on how consistently the protocol gets followed, and compliance is tied to outcomes.
Validated Across 250,000+ Procedures
Recommended by orthopedic surgeons and used by professional sports organizations.
The NICE1 has supported more than 250,000 procedures and is trusted by professional teams across the NFL, NHL, MLB, NBA, and international soccer, including the New York Yankees, Pittsburgh Steelers, Colorado Avalanche, Manchester United, and Atlanta Hawks. Orthopedic surgeons at institutions like The Steadman Clinic specify the NICE1 for their post-surgical patients as the home standard for cold and compression therapy.
How to Rent the NICE1 Before Surgery
Arrange it early so it arrives before day one of recovery.
Renting starts with the form on the rental page. Once you submit it, an authorized distributor in your area contacts you within 3 to 5 business days to confirm your delivery date, address, and rental duration. Arrange the rental at least seven days before your surgery date so the unit is set up and ready when you come home. The initial rental period runs about two weeks, which covers the acute phase when consistent cold and compression do the most work, and you can extend if your protocol calls for it.
Frequently Asked Questions
Common questions about renting the NICE1 and how it compares to the DonJoy IceMan.
My surgeon prescribed a DonJoy IceMan. Can I use the NICE1 instead?
Ask your surgeon. Most cold therapy protocols specify cold or cold and compression as the modality, and the device named is often a default recommendation rather than a requirement for one brand. If the protocol calls for combined cold and compression, the NICE1 delivers that on every rental, and the IceMan does not offer compression at any tier. That conversation is best had before your procedure date.
Does the NICE1 work with DonJoy IceMan pads?
No. The NICE1 uses its own anatomical wraps, designed specifically for the device's combined cold and compression delivery. NICE1 wraps are available for the knee, hip, shoulder, elbow, ankle, wrist, lumbar, and more, and your rental includes the wrap appropriate for your procedure.
How does an iceless device stay cold for hours?
The NICE1 uses a thermoelectric core, the same technology class used in precision lab cooling equipment. It actively removes heat from the water circulating through the wrap rather than relying on a melting ice supply. As long as the unit is plugged in, the temperature holds. Sessions running four, six, or eight hours keep the same skin-surface temperature throughout.
How far in advance do I need to schedule my NICE1 rental?
Fill out the rental form and an authorized distributor in your area will contact you within 3 to 5 business days to finalize delivery. Arrange it at least seven days before your surgery date so the unit is ready before you need it.
What does renting the NICE1 cost?
Rental pricing is set by authorized distributors and varies by region and duration. For most post-surgical patients whose primary need falls in the first four to eight weeks, renting is the more cost-effective choice. When you compare total cost against buying an ice-water unit, factor in the daily ice that system needs across the same period.
