You're standing in the appliance aisle, staring at a sleek, metallic beast of a machine that costs $200 more than the base model because it has a "Steam Refresh" button. It sounds fancy. It sounds like you'll never have to touch an iron again. But honestly, most people buy a dryer with steam function and then just... never use it. Or worse, they use it wrong and end up with a soggy pile of jeans that smells like a wet basement.
I’ve spent years looking at how these machines actually work, and the truth is a bit more nuanced than the marketing brochures suggest. It’s not a magic dry-cleaning wand. It’s a specialized tool. If you’re the type of person who leaves a load of laundry in the dryer for three days until it’s a wrinkled mountain of despair, this might be the best investment you ever make. If you’re a laundry perfectionist who folds everything the second the timer dings? You’re probably throwing money away.
How a dryer with steam function actually works (No, it’s not a sauna)
Most people assume the dryer just gets really hot and misty. That’s partly right, but the execution matters. In a standard dryer, you have heat and tumbling. That’s it. When you add a steam cycle, the machine introduces water—either through a dedicated cold-water line or a manual reservoir—and hits it with a heater to create vapor.
There are two main ways manufacturers like LG, Samsung, and Whirlpool handle this. Some machines use a "mist" spray where tiny droplets hit the hot drum and turn into steam. Others have a dedicated steam generator that shoots actual vapor into the chamber. The goal is to relax the fibers of the fabric. Think of it like what happens to your hair in high humidity; it softens and shifts. By relaxing those fibers while the drum is tumbling, the dryer can shake out the wrinkles that set in while the clothes were sitting still.
It's also about chemistry. Odors are often trapped in the fibers. Steam helps "open" those fibers up, allowing the heat to whisk away the molecules that make your shirt smell like yesterday’s takeout. But don't expect it to fix a shirt that has literal armpit stains. Steam is for "I wore this for two hours and it’s not dirty, just rumpled," not "I ran a marathon in this."
The "Ironing is Dead" Myth
Let's be real: a dryer with steam function is not going to give you those crisp, razor-sharp pleats on a tuxedo shirt. If a salesperson tells you that you'll never iron again, they're lying.
Steam cycles are fantastic for cotton blends, polyester, and knitwear. They are mediocre for heavy denim and almost useless for 100% heavy linen, which basically requires a professional press or a high-heat iron to look decent. I've seen people toss a crumpled linen blazer into a steam cycle and come back 20 minutes later to find a slightly less crumpled, but now damp, blazer.
What it actually excels at:
- The "Oops, I forgot" scenario: You left the laundry in the dryer overnight. It's now a structural block of wrinkles. A 15-minute steam refresh will save you an hour of ironing.
- De-funking pillows: You shouldn't wash decorative pillows constantly, but they get dusty. A steam cycle can kill dust mites and freshen them up.
- Reducing static: Winter air is dry. Steam adds just enough moisture to stop your socks from clinging to your sweaters like velcro.
The plumbing headache nobody mentions
You have to get water to the dryer somehow. This is where the "hidden costs" come in. Most high-end dryers require a "Y-connector" that splits the cold water line going to your washing machine.
If you're DIY-ing this, be careful. I’ve seen plenty of laundry room floods because someone didn't tighten the brass fittings or used a cheap rubber hose that cracked under pressure. If your laundry room doesn't have an easy way to split the water line, you might have to look at models with a manual reservoir. These have a little drawer you fill with distilled water. It's a bit of a pain, honestly. You'll forget to fill it, or the water will sit there for months and get gross.
Sanitize cycles and the health factor
One of the biggest selling points for brands like Maytag or GE is the "Sanitize" cycle. This is different from a standard dry. By combining high heat with steam, these machines can claim to kill 99.9% of common household bacteria.
According to the National Sanitation Foundation (NSF), for a dryer to be certified for sanitization, it has to reach a high enough temperature for a specific duration. Steam helps bridge that gap without scorching your clothes. If you have a baby in the house, or if someone has a compromised immune system, this isn't just a luxury—it’s a genuine utility. It's great for cloth diapers or bedding after someone’s had the flu.
A warning on delicate fabrics
Just because it's "vapor" doesn't mean it's gentle. Steam is hot. Really hot. If you put a delicate silk blouse or a wool sweater in a high-heat steam cycle, you're going to end up with a doll-sized version of your clothes. Always check the care label. If it says "dry clean only," keep it away from the steam dryer. The moisture can cause certain dyes to bleed or fibers to shrink unpredictably.
Comparing the big players: Who does it best?
Not all steam is created equal. If you're shopping right now, you'll see a few different terminologies.
Samsung uses "Steam Sanitize+" which they claim removes 95% of allergens. Their "Multi-Steam" technology is designed to be more "tangle-free." LG is famous for its "TurboSteam" which is incredibly fast—perfect for when you realize your favorite shirt is wrinkled 10 minutes before you have to leave for work. Whirlpool often focuses on "Steam Refresh" which is a more basic, effective misting system.

If you're choosing between them, look at the cycle times. Some machines take 30 minutes to run a "refresh" cycle, which is way too long if you're in a rush. You want a machine that can do a quick blast in under 15 minutes.
Is it worth the electricity?
Usually, no, it's not a huge energy hog. The steam generator only runs for a small portion of the cycle. However, if you are constantly running "Refresh" cycles instead of just folding your laundry, you're obviously using more power than someone who doesn't.
Energy Star ratings typically focus on the efficiency of the drying process itself, but using steam can sometimes shorten the drying time for very dry, wrinkled clothes because the moisture helps conduct heat more effectively. It’s a wash, pun intended.
Real-world maintenance you can't ignore
If you have hard water, you're going to have a bad time eventually. Calcium and magnesium deposits will clog the tiny steam nozzles inside the drum. Over time, you might notice the steam function isn't "steaming" anymore.
You can't really "descale" a dryer easily like you can a coffee maker. If you live in a place with heavy mineral content in your water (looking at you, Arizona and Florida), a dryer with steam function might have a shorter lifespan than a standard model unless you have a whole-house water softener.
Also, check the drum for "hot spots." Occasionally, the nozzle can get slightly misaligned and spray water directly onto the drum wall rather than into the air, leading to some localized rusting over five or six years if the porcelain coating is chipped.
The Verdict: To steam or not to steam?
If you are a "set it and forget it" laundry person, get the steam. It will save you from the embarrassment of wearing a shirt that looks like it was balled up in a gym bag. If you have kids who bring home every germ known to man, get the steam for the sanitization.
But if you’re on a tight budget? Skip it. You can get 80% of the same result by tossing a damp washcloth into a regular dryer with your wrinkled clothes for 10 minutes. It’s the "poor man's steam cycle," and it works surprisingly well.
Actionable Next Steps
- Check your hookups: Before you buy, look behind your current washer. Do you have space for a Y-connector, or will you need a reservoir model?
- Audit your wardrobe: Do you actually wear "refreshable" clothes? If you wear mostly heavy denim or delicate silks, the steam function will sit idle.
- Measure your vent: Steam dryers pump out a lot of humid air. Ensure your dryer vent is clear of lint and hasn't been crushed; otherwise, that steam will just turn into condensation and mold inside your walls.
- Test the "Damp Washcloth" trick: Before spending the extra $200, try the wet towel trick in your current dryer. If that satisfies your wrinkle-reduction needs, you don't need the upgrade.
