Outdoor Misting Fan: The Top 3 for Workers Compared

Outdoor Works Misting Fan

There’s work and then there’s hard labor. While people sitting in their office cubicle complain about their coffee being too cold, men and women everywhere are scooping, digging, raking, picking, scrubbing, lugging, and more. And on most days, they’re outside at the mercy of the elements. As the weather warms up, overheating becomes an increasing concern for these workers.The United States Department of Labor even has an ongoing “Campaign to Prevent Heat Illness in Outdoor Workers.”

Outdoor Workers Heat

Outdoor workers are susceptible to heat illness when temperatures rise.

One way to combat hot temperatures in such workplaces is with an outdoor misting fan. This appliances work exactly as the name suggests: they use water, combined with air blown by a fan, to cool an area down. The fan head usually has several nozzles or a centrifugal pump system through which the water is sprayed, and this cool mist is then spread and circulated by the fan. Some mister fans draw water from a storage tank, while others can be directly connected to a hose.

There are many outdoor mist fans on the market, but not all will get the job done. Whether you’re an employer seeking to keep your hard-working crew cool, or an employee who wants to take the initiative to prevent heat stress, or a DIY enthusiast looking for a solution to being too hot in your own backyard, the below guide summarizes 3 popular outdoor misting fans so you can make a quick decision on which one to purchase. At the bottom of the article, you can find a quick reference chart of each mister’s main specs.

Lasko 7050 Misto Outdoor Misting Fan

Lasko 7050 Misto Outdoor Misting Fan for Work

Lasko 7050 Misto Outdoor Misting Fan

Cooling Coverage Area

The Lasko 7050 is one of the most popular outdoor misting fans because it’s a compact, low profile unit at a low price. Customers have found that this product can cool areas up to about 30 square feet. This means this fan is more suited for personal use in an outdoor work space, and you would need one of these for every few workers.

Temperature Drop and Water Connection

Within its cooling radius, Lasko’s outdoor misting fan can drop temperatures by about 25°F. To use this appliance, you must have access to a continuous water supply, and it comes with a 9’ water hose that attaches to a standard garden hose. This fan mister has no water tank and so will only run for as long as you have the spigot turned on.

Oscillation, SpRAY, and Fan Speeds

The actual fan component on the Lasko 7050 Misto does not oscillate, but it can be pivoted on a 90° angle. It also has louvers that automatically oscillate/move to create a wide misting sweep. You can choose between 3 fan speeds — low, medium, and high — and there are 3 misting nozzles. This outdoor mist fan is very effective at cooling within a close range, though one customer complaint is that it gets everything which is too close — i.e. under 5 feet — too wet.

Lasko 7050 Misto Outdoor Misting Fan Nozzles

The Lasko 7050 Misto Fan front misting nozzles and fan louvers.

Base, Dimensions, and Construction

The Lasko outdoor misting fan is very small, but heavy for its size. It measures 12.3″L x 16.25″W x 14.85″H and weighs 16.7 pounds. The fan sits very low to the ground and so you’ll need to use the pivot feature to direct the mist upwards. It does not have wheels, but does have a large carrying handle on the rear. This misting fan is made out of plastic and is designated as weather, UV, and rust-resistant. It’s also intended for outdoor use only, and so is engineered to hold up under the elements.


The Lasko 7050 outdoor misting fan runs for about $115. This is fairly inexpensive, but it’s important to remember that this model has a relatively small cooling area. Thus, this portable mister would be most suitable and cost-effective for small outdoor crews or for home outdoor projects.

Luma Comfort MF26B 26″ Commercial Misting Fan

Luma Comfort MF26B Outdoor Misting Fan for Workers

Luma Comfort MF26B Commercial Outdoor Misting Fan

Cooling Coverage Area

The Luma Comfort MF26B is considered a commercial misting fan and is ideal for larger-scale applications than the Lasko 7050. That’s because it offers a substantially wider coverage area of 1,000 square feet. This mister fan is specifically designed for cooling big areas such as athletic fields, greenhouses, and more.

Temperature Drop and WaTer Connection

The MF26B commercial mist fan can also provide a more significant reduction in ambient temperature, with a 30-45°F drop, and operates with optimal output in temperatures up to 104°F. That means that it can bring the working temperature down to a nice 70°F or below in extreme heat conditions. Unlike the other two misting fans on this list, Luma Comfort’s product runs off of a water tank, with a 5 hour misting time. The tank can hold up to 4.4 gallons of water. This makes this outdoor cooler more convenient if you don’t have immediate access to a water hose line. However, it will require refilling once during an 8 hour work day.

Oscillation, Spray, and Fan Speeds

Luma Comfort’s misting fan combines a high pressure, centrifugal misting system with a blower fan. That means there are no misting nozzles and thus no possibility of clogging from hard water build-up. There are 3 fan speeds to choose from — low, medium, and high — with respective RPMs of 1400, 1500, and 1700. This outdoor fan has a very wide head, at 26 inches across, and when combined with the oscillation option, is highly effective at cooling horticulture, agriculture, and commercial operations.

MF26B Outdoor Misting Fan Close Up

The Luma Comfort MF26B uses centrifugal technology instead of misting nozzles.

Base, Dimensions, and Construction

The Luma Comfort MF26B is a fairly heavy appliance, weighing 89 pounds. Its dimensions are 17.30″L x 26.00″W x 76.60″H, so it has a much bigger footprint than the Lasko 7050, with the most space required vertically on this list. However, this fan is considered a “pedestal misting fan with cart.” In other words, it has a pedestal base that has wheels on the bottom, and handles on the fan stand. So while it’s more unwieldy in terms of overall size, it’s still easy to move around between work locations. This outdoor mist fan is made out of heavy-gauge, anti-corrosive stainless steel, and is weather-resistant.


The Luma Comfort MF26B Outdoor Misting Fan costs approximately $750. While this is substantially more than the Lasko 7050, it does provide over 30x as much cooling coverage area. This product would be a better investment than the previous fan we looked at if you’re looking to cool workers in big commercial spaces.

NewAir AF-520B 18-Inch Ultra Quiet Outdoor Misting Fan

NewAir AF-520B Outdoor Misting Fan for Work

NewAir AF-520B Outdoor Misting Fan

Cooling Coverage Area

One of the most popular misting fans available, NewAir’s AF-520B rides the middle ground between the previous two products we looked at. It can provide cool mist in spaces up to 500 square feet. This makes it still suitable for larger work space applications and also appropriate for home DIY project use.

Temperature Drop and Water Connection

Customers have found that NewAir’s misting fan is effective at dropping temperatures by about 30°F. Like the Lasko 7050, this outdoor misting fan does not have a water tanks and instead works via a connection to a standard 0.75″ garden hose. As long as you have a supply of running water coming through the hose and the fan’s misting hose valve turned on, this unit will continue to provide cool air.


The NewAir AF-520B has an 18″ wide fan head that oscillates. Unique from the other two models, it also is a fully adjustable head, meaning that it can be tilted in different directions for concentrated cooling. Furthermore, the height of the actual fan stand can be changed with an adjustment knob, for low-reaching, high-reaching applications, and anything in between. Just like the other two outdoor misting fans, this one has 3 fan speeds to choose from: High (50W), Medium (45W), and Low (40W). This product has 3 misting nozzles and the fan can be used without the misters turned on.

As an outdoor misting fan, the NewAir AF-520B is supposed to used outdoors. That means it can be left outside in the elements and it will still start-up without a problem. This product is constructed from weatherproof plastic and metal. At its tallest, it measures 19.38″L x 19.38″W x 55.00″H. This outdoor misting fan is lightweight at just 16 pounds, which is less than the more compact Lasko 7050. However, the AF-520B mister does not have wheels on its pedestal base or a carrying handle, so is more inconvenient to transport.


The NewAir AF-520B costs approximately $130, making it a nice mid-range outdoor misting fan. It can effectively cool several workers at once, though is probably most-effective for backyard work projects or smaller landscaping applications.

All of these misting fans would be helpful in cooling off outdoor work zones. If space is an issue and you’re seeking more compact, immediate cooling, the Lasko 7050 Misto is a good choice. However, the NewAir AF-520B mister provides a nice balance between more commercial-grade cooling power and cost-effectiveness, and would be a good investment in casual work scenarios — though it might not be as effective in heat extremes as the Luma Comfort MF26B Outdoor Misting Fan. The MF26B is by far the most powerful and effective option for commercial work spaces, so if you or your workers are repeatedly exposed to higher temperatures, this is the best misting fan option.

8 Quick Tips about Misting Fans


misting-fansSummertime is meant to be spent outdoors. However, the immense heat can take a toll on your skin. Most people even fall ill if they are exposed to too much heat. This is why one should consider outdoor cooling options. The best way to remain cool while outdoors is to use a misting fan. You can install a misting fan near your pool or on the deck. It will help you stay cool during the summer.

1. Use Misting Fans Anywhere

Misting fans a great option for keeping a particular area cool. These fans actually spray mist along with distributing air and keeping the area cool. Misting fans can provide cooling in every area. In fact, it is a better option than air conditioning systems. Air conditioning systems require a closed space to provide substantial cooling. They cannot cool outdoor areas. Misting fans work in a different fashion and therefore prove more effective in outdoor areas. You can use a misting fan indoors as well. Depending on your preference, you can get portable or stationary misting fans. This allows you to use a misting fan almost anywhere. The Luma Comfort MF26B even comes mounted on a cart so that you can wheel your cooling mist anywhere it’s needed.

Luma Comfort MF26B misting fan2. Always Follow the Instructions in the Owner’s Manual

Misting fans use water to keep an area cool. This is why you should exercise certain precautions to ensure your safety and the unit’s proper functionality. The first and foremost precaution you should take is to keep the fan away from electricity. Since it sprays mist, it should not be kept close to electrical circuits. Misting fans may cause wires and circuitry to build up moisture which could lead to a short circuit. This can cause an electrical fire. Moreover, you should keep any items that are sensitive to water away from misting fans. For instance, if you have wooden furniture or other items that can be damaged by water, be sure to keep them at a distance.

3. Use Proper Spray Nozzles for the Best Cooling Effect

In essence, a misting fan works seamlessly to cool an area in any sort of an environment. However, there is a common misconception that it does not work well in humid areas. Misting fans create a mist. This gave rise to the idea that it will only make a humid environment more unpleasant by adding the mist. Fortunately, this is not the case. The only time a misting fan will make an environment unpleasant and humid is if the nozzles are not in working order. Otherwise, misting fans work best in areas where there is humidity. Since it is a cooling device, it is meant to be used in warm climates.

4. Maintain Your Misting Fan Properly

Another common misconception regarding misting fans is that they make everything near them wet. This is true to a certain extent, but only if it is used improperly. When the tiny water droplets are sprayed into the air, they cool off the air and then evaporate. However, misting fans are not supposed to cause a water buildup in the surroundings.

Water accumulation is usually caused when these fans are used indoors. While it is safe to use these fans indoors, you have to provide a proper ventilation source. If there is no ventilation available, there is a chance that the water will accumulate somewhere. But this is not because the misting fans do not work properly. It’s simply because the water drops don’t get the chance to evaporate.

Another reason why misting fans may cause moisture buildup is because the right nozzles have not been used. Always use manufacturer specified parts when maintaining fans. This will ensure proper functionality and prevent problems such as moisture buildup.

5. Make Sure the Area is Well Ventilated When Using the Fan

Misting fans can be used in any environment. However, you have to make sure that the area is well ventilated. If not, the misting fan could cause water buildup on objects near it. Moreover, you should not keep misting fans in areas with heavy foot traffic. Instead a misting fan should be kept in a corner where no one can touch it. If a misting fan is kept near people, someone could end up bumping into it. This can be a big problem as certain misting fans are balanced on top of a water tank. Should the water spill onto the electrical components, it could cause a short circuit. The fan could also end up being damaged in the process.

6. Keep Yourself Cool without Getting Wet

Many people believe misting fans make people wet. They believe that misting fans spray water on people and make them wet to stay cool. However, misting fans work quite differently. In fact, they do not make the surroundings wet. The tiny water droplets that are sprayed into the air cool down the surrounding air. Once the air is cooled the droplets evaporate. This is because the water droplets are immensely small. They do not have the density to make anyone wet. There is a chance of this happening, but only if the fan is malfunctioning. There are certain misting fans that are built with inferior quality materials. The nozzles used in these fans cause people and surroundings to get wet.

7. Consider the Best Water Supply Option

There are many different types of misting fans available in the market nowadays. Some are portable, while others need to be hooked to a water supply. For most portable models, there is a built-in water reservoir in the misting fan itself. You simply need to fill it with water and use it. On the other hand, there are some misting fans that require a large water tank or supply. However, this depends purely on the type of misting fan you choose. If you are at a distance from a water source, you should consider using a misting fan with a tank. You will need to refill the tank once the water runs out.

Luma Comfort MF18W misting fan8. Direct Water Hookups Offer Added Convenience

The misting fans that are available nowadays are more convenient than ever before. They do not have to be filled after the water runs out. Instead, the Luma Comfort MF18W provides a continuous supply of misting comfort. You can simply hook up your misting fan to a standard garden hose. The fan will continue working till it keeps receiving water from the faucet. If you are far from a faucet, you can use a tank or a reservoir to provide water.

Entertaining with Easter Traditions

Every year for Easter, my family’s tradition is to play a concert at sunrise in a cemetery. It’s one of those odd experiences that you can’t tell people without an odd look and a “You did what?” asked. We arrive at 5 a.m. for set up (which usually means that we’ve been up since 3) and a little warm-up rehearsal. Some years, we make up almost a fourth of the symphony orchestra—mom plays French horn, dad plays trumpet, I play violin, my sister plays flute.

We start playing right around 6 a.m. and the sun rises while we’re playing. One second we’re playing in the dark and it’s hard to see, the next moment we get a brilliant ray of light and our music is illuminated. However, then we usually come home and fall asleep in odd places. I fell asleep on the floor of the entryway last year, still wearing my black concert clothes (I am not a morning person). When we finally come out of this concert-induced coma, we pick ourselves up and have a nice dinner. Easter eggs are usually an afterthought, but there are always deviled eggs with dinner.

Easter traditions have been around since the first days of the holiday. The name for Easter comes from “Eastre”, a pagan Saxon goddess of spring, fertility, and dawn. She is also where we get the English word “east” because she was known to “hang out” with the sun go, since the sun rises at dawn in the east. Before you entertain your family and friends over the holiday weekend, take a moment to learn about how these Easter traditions came to be.

Easter Bunny

The Easter Bunny, also known as the Easter Rabbit or Easter Hare, was originally much like the Santa Claus legend. He would act as a judge to the children, determining if they had been good or bad during that season. The good children would be given gifts and eggs the night before Easter for them to discover in the morning. The bad children would be left unrewarded.

However, his origins go back much further than that. Before the bunny was mascot of a specific holiday, the hare was a symbol of fertility in ancient times. Ancient scholars, such as Pliny, Plutarch, Philostratus and Aelian, thought that the hare was a hermaphrodite, which explained its ability to excessively breed. Later, the medieval church would adopt the hare motif in its church art and it became associated with the Virgin Mary.

The Easter Bunny that we know and love originated among the Germans. He was called “Osterhase,” which translates to Easter Bunny. This character was first mentioned in De Ovis Paschalibus (About Easter Eggs) by Georg Franck von Franckenau in 1682. The book also talked about how children would hunt the eggs hidden by this bunny.

German immigrants brought this legend to Sweden in the late 19th century, but the Swedish word for Easter Bunny, “Paskharen,” sounds remarkably similar to “Paskkarlen,” which means Easter Man or Easter Wizard, so the Swedes have a tradition of an Easter Wizard bringing eggs. This is a relatively new tradition, dating to the early 20th century. Some children even dress up as Easter witches to celebrate the tradition. It also has some roots in old Nordic folklore, in which witches would travel to “Blue Hill” to visit the devil during this time of year.

The Easter Bunny was also brought to America by German immigrants. The legend reached the US in the 18th century, when German immigrants were settling in the Pennsylvania Dutch region. Good children would prepare for the Easter bunny by making nests in their caps and bonnets so that the bunny could lay his eggs here (Yes, he is traditionally a male bunny, but with the magic ability to lay eggs).

Easter Eggs

Decorated eggs have long been a part of many different global celebrations. The practice of decorating eggs is ancient and well-established in the archaeological record. In Africa, ostrich eggs with carved designs have been found that are estimated to be 60,000 years old!  Silver and gold representations of eggs were also found in burial sites of the ancient Sumerians and Egyptians. The egg symbolized rebirth and was used in Pagan celebrations of spring. It was adopted by early Christians as a symbol for Easter and the resurrection of Jesus. The first use of Easter eggs for the holiday is attributed to the early Christians of Mesopotamia, who stained eggs red to celebrate the holiday. Since eggs and dairy were forbidden during the period of Lent, eggs were consumed before the period began, then they were stored up for the celebration of Easter, which also marks the end of Lent.

Did You Know? The International Association of Bomb Technicians and Investigators (IABTI) sponsors an annual charity campaign in the US to build beeping Easter eggs for visually impaired children.

The Easter Bunny has been the official bringer of Easter eggs since the 17th century. The Easter egg hunt is a much-beloved tradition for many countries and cultures that celebrate Easter. The egg hunt was also a popular game for spring time birthday parties. The Guinness Book of World Records recorded the largest Easter egg hunt on April 1, 2007– 9,753 children searched for 501,000 eggs at the Cypress Gardens Adventure Park in Winter Haven, Florida.

Easter egg decorating has also been elevated to an art form. From 1885 to 1916, the Faberge workshops created the annaul jeweled Easter eggs for the Russian Imperial Court. Each egg took a year or more to make and often depicted important milestones of the Romanov family. The 1913 Winter Egg is carved from rock crystal, with 3,246 diamonds. It is valued at over $9.6 million.

Pysanka Easter Eggs

In the Ukraine, pysanka eggs are decorated using a special batik, a wax-resist, method. The design is drawn onto the egg with wax and then dipped into dye. In Mexican tradition, Cascarones are eggs that have been emptied and filled with confetti for the egg hunt. When the eggs are found, children (and adults) smash them over each other’s heads. In Sweden, Norway, and Germany, decorated eggs are hung from tree branches as centerpieces for the table. At the White House, the Easter Egg Roll is held annually and children can roll the Easter eggs across the president’s front lawn.

However, decorated eggs aren’t just for the egg hunts. “Egg tapping” or “egg jarping” is a popular game in England, in which each player must hit their egg against another player’s. The winner is the person who keeps their egg from breaking. There is even an annual egg jarping world championship held at Peterlee Cricket Club each year. Yes, a world championship of egg breaking. Another popular activity is to celebrate Easter with an egg dance. People in Germany and the UK place the eggs on the ground and try to dance among them without landing on the eggs. My guess is that they do this outside or somewhere they can hose the mess down later.

Easter Entertaining

So, try something new this Easter. Invite your friends and family over for an egg dance or use crayons to try your hand at pysanka eggs. A misting fan can keep your backyard cool for the kids. Temperatures could reach 79⁰F in Southern California on Easter Sunday. Begin training sessions for the egg jarping world championship. Make a nest for the Easter bunny in your favorite baseball cap.

Or buck tradition and start a new one. A backyard BBQ wouldn’t be the traditional choice for food, but hot dogs and burgers are always crowd pleasers. For the adults, try a Blue Cotton Tail (1.5 ounces of vodka, .5 ounces triple sec, and .25 ounces blue curacao) or an Easter Fizz (2 ounces of brandy, 1 egg white, 1 teaspoon powdered sugar, 1 ounce half and half. Shake hard and dust with a sprinkling of nutmeg). A portable ice maker can provide enough ice for cold beverages all day long.

You could also take the kids on a hunt for the Easter bunny. Plant some clues, like an egg trail or a bit of his cotton tail stuck in a bush (cotton balls). At the end of the hunt, leave the baskets with a note from the Easter bunny that says he barely got away this time and to try again next year.

If you really want to be original with your holiday traditions, egging houses with Easter eggs has probably never been attempted before.

Luma Comfort MF26B Misting Fan Blows Man Over


Patio Cooling for Memorial Day

Pool deck with an outdoor evaporative coolerHappy Memorial Day weekend everyone! It’s an exciting time around here, because it’s officially the start of Summer BBQ season!

While we’ve talked a lot about using our misting fans outside on your patio or pool deck, did you know that an evaporative cooler can also be a great outdoor cooler? They’re particularly useful for parties. Unlike misting fans, which spray a water mist – albeit a dry one – evaporative coolers only blow cold air. This makes them a great option when you’re looking for cooling, but would rather not have any mist.

Our Luma Comfort units are also portable, so they’re easy to move around for short term events – like your Memorial Day BBQ!

So this weekend try out your swamp cooler on the patio and let us know how it goes!

The Best Back Yard Misting Fan

MF18W Back Yard Misting Fan

We gave this unit a lot of love last year, but with the weather warming up here in Southern California, we knew it was time to talk misting fans once again!

A few people have asked us recently what made our MF18W misting fan different than the competition. Here are a few thoughts:

  1. The fan is made of metal, meaning it will last a long time. Much longer than less-expensive plastic models.
  2. A direct hose connection means you never have to fill the bother filling up a tank with water. Nothing slows down a back yard bash like having to stop and re-fill your misting fan.
  3. Safety is its middle name! Well, not really, but the GFCI plug protects you from shock and ensures the unit is 100% safe for indoor and outdoor use – just try not to turn the misters on inside!
  4. The Luma Comfort brand name means you’re getting a quality product along with a full 1-year warranty. We do more than just stand by our products – we are downright proud of them, and we want you to love them just as much as we do.

Check out the video we put together below to learn more about why we love our MF18W misting fan so much!

Dreaming of Summer – and Misting Fans!

Tennis 2013 - Australian Open - Day 4

Looks cool doesn’t it?

While most of the US is in the middle of winter, down in Australia, it’s the middle of another beautiful summer. With the Australian Open Tennis Championship under way this week, many tennis fans will be spending long days out in the hot sun. Luckily, the folks at the Autstralian Open are well prepared with our favorite type of cooling solution – Misting Fans!

And while no, they’re not using the awesome Luma Comfort misting fans down under, they very well could be! In particular, the MF26B Commercial Misting Fan would be a perfect choice for cooling off large crowds, thanks to its 1,000 square feet of cooling power.

So while you’re walking through the cold at some point this month, just remember the above photo, and know that’re only a couple months away from Misting Fan Season!

Misting Fans Save the (Race) Day in Indy

Indianapolis 500 Race Track

Sunday’s Indianapolis 500 was nearly the hottest race day on record, with the temperature topping out at 91 degrees. The on-track temperature was even warmer, hitting 133 degrees midway through the race. Luckily for race fans, officials in Indy were prepared for the heat. According to the Indianapolis Star, track officials set up 78 misting fan stations throughout the Speedway. They received rave reviews from fans too:

“Those little misting stations are awesome,” Rose said. “It’s making it easier to stay cool.”

Thanks to proper planning and the large number of misting areas available, there were fewer medical issues and emergencies than track officials had initially feared. While roughly 200 fans were treated at the Speedway on Sunday, the majority were the result of intoxication.

As the summer goes on, expect to see misting fans pop up at outdoor events across the country to keep people cool and safe from the heat.
