Promising review: "Can't beat the price! Great adhesive strength. Using in Texas weather on doors to seal air leaks. The weatherproofing material itself is very pliable and soft, presuming it weathers the heat and humidity.

5. A flexible adjustable mister to help you keep your outdoor space an inhabitable temperature whether you've got a full gardening itinerary planned or just want to lay in the sun without overheating immediately.
The mister will cool the surrounding area by 20 degrees, and it comes with an interchangeable flower-shaped misting head for a fun, whimsy detail.
Promising review: "Works exactly how I want it to. Provides a fine, cool mist on the patio, allowing us to enjoy the backyard until sunset without breaking a sweat. Easy to set up. It was out of the box and cooling us off within minutes." —Debra L. Kusek

Promising review: "Absolutely love this system. Keeps us cool in the late afternoon hot sun. Makes the patio bearable. The original packaging was missing a part, contacted the seller and they sent me new parts immediately. The nozzles turn the water to mist effectively. They will drip a bit when you turn it off. Haven't had problems with scaling or buildup, and we have very hard water here. Would buy it again if needed." —KMUL
Get it from Amazon for $22.99.
7. A chic Windmill window AC because most air conditioners are kind of an eyesore, but this one looks great and preforms even better. It's efficient, quiet, simple to install, and can be controlled from anywhere with your smartphone. Switch it on during your commute home and enjoy walking into a freshly chilled space!
Windmill is an independent AC brand that aims to combine three generations of family knowledge in the air conditioner business with an updated design fit for modern living.

Get it from Amazon for $349 or from Windmill for $324+ (available in three BTU levels and four colors).
8. Or an energy-efficient 2-in-1 air conditioner with a genius U-shaped design that uses your window to block out noise, making it nine times quieter than standard units. Plus, it's Wi-Fi compatible so you can adjust controls from your phone with the app or via voice commands with Alexa or Google Assistant.
Promising review: "I don’t usually write product reviews, but I am now because this is one of the best household products I have ever bought. This Midea U-shaped AC is an ingenious design that is basically a split AC system mounted in a window, with the window closing almost all the way through the middle of the unit. The result is a much quieter and more efficient unit, with the noisy part that generates heat on the outside of the closed window. It also looks sleek and modern and the remote control and app are great. I have thought many times 'I wish someone would make a split AC system that can fit in a window without having to install separate units on the roof or wall,' and now they have!" —Ben
Get it from Amazon for $399+ (available in three BTU levels).
9. A fast-acting HyperChiller for keeping you cool and caffeinated without a designated trip to a coffee shop. This magical vessel uses multiple chambers, stainless steel, and plain ole water to chill a fresh cup of hot coffee to iced perfection in just 60 SECONDS.
This 12.5-oz. cup chills all beverages except carbonated ones (think tea, juice, and even wine). You fill it with water and put it in the freezer for 12 hours before using it. Plus, it's dishwasher-safe!
Promising review: "I’m the type of person who loves ice coffee any day and I like to take my time drinking it. This HyperChiller has truly changed my life! It’s super easy to put together and clean! Also, the fact that you can pour your hot coffee directly into it is amazing! It’s super fast at making your coffee cold, and it never tasted watered down at all! I am so amazed and happy by this invention, 100% recommend everyone buys it." —Catherine D
Get it from Amazon for $23.99+ (available in four colors).
10. A pillow top cooling mattress topper if you're tired of regular foam toppers that slide around all night and aren't breathable. This one has a deep pocket that'll fit around most mattresses and will help keep you cool all night long (so you can pile on the blankets, duh).
Promising review: "With the night sweats I’ve been experiencing, this was a nice addition to my bed. It keeps me cool in the evening, and is really comfortable to sleep on. I was surprised. It was inexpensive so I was not expecting much, but am pleasantly surprised by the great quality." —kylie ryan
Get it from Amazon for $38.98+ (available in sizes Twin–Cal. King and in three colors).
11. A compact USB desk fan to make your workspace the ~coolest~ place to be. Its small size doesn't eat up precious surface area, and it's quiet enough to run during meetings without disturbance.
I bought this fan (the 4-inch version) last summer to hold me over until I could get proper air conditioning, and it has absolutely exceeded expectations. It cools me off remarkably well for such a small fan, and it's really quiet, too! I love how it's made from metal, not plastic, which gives it a more upscale look, and how I can just plug the USB cable into my laptop when I need a little help cooling off during work.
Get it from Amazon for $12.99+ (available in two sizes and in two colors).
12. A pressure-activated cooling gel mat so you can get your dog through those dog days of summer with up to three hours of continuous chilled relief. And don't worry, the mat only needs to go unused for 15–20 minutes to fully recharge its cooling powers.
Promising review: "I’ve only had it two days, but clearly our double-coated dog approves. He has never slept up on the couch with us, he just gets too hot. Now he’s curled up against me on his pad snoozing away. I’m so happy!!!! I don’t care if it lasts six months or six years — it’s worth it that he’s comfortable." —Crystal S.
Get it from Amazon for $27.98+ (available in two sizes, two colors, and in larger sizes).
13. And a reusable XL gel ice pack to keep the humans cool, too. It stays comfy and flexible straight out of the freezer, so you can soothe aching muscle or replace your couch cuddle buddy with it on those days when it's entirely too hot to be touched.
Promising review: "This is an excellent ice pack for injuries, but I also found it to be surprisingly useful when it was really hot this summer and the power was out as a result of a recent hurricane. Sitting and laying on the ice pack really cooled me down and felt amazing!! At the time, I wished that I had bought more than one." —E. J. Tompkins
Get it from Amazon for $33.99.
14. A silicone stick ice cube tray with a built-in lid because your water bottle's narrow opening shouldn't get between you and some ice-cold refreshment.
Promising review: "Very solid construction and good design. The cover (I think it's silicone) works great at keeping freezer smells off the ice. The cover is also used to drain excess water after filling the tray, you just hold down the cover and water channels will drain excess water before putting in the freezer. Removing the ice is easy. The shape of the ice easily fits in any water bottle I've used." —D. Harlan
Get it from Amazon for $10.95.
15. A set of blackout curtains with a triple weave liner for blocking out the light, while insulating against both summer heat and winter chill. They come in a wide range of colors, so you can pick up a pair for every room without clashing with your decor.

Get it from Amazon for $33.99+ (available in a variety of sizes and colors).
16. A heavy duty roll of transparent weather sealing tape that'll discreetly insulate all that unavoidable gapping from your window AC, creating an air- and waterproof seal that won't leave behind any damage or sticky residue when it's time to uninstall your units.
XFasten is a small business that launched in 2015 selling a wide array of adhesive products from home improvement accessories to craft supplies.
Promising review: "Needed something to keep the cold out from an old window allowing cold winter air in after a recent window AC unit install. This did the trick! Cold air used to be felt blowing through the area of the window above the unit, but after sealing the window with this tape it’s really helped! I no longer feel the blast of cold air, and hopefully it will also help keep the heat out in the summer as well! Highly recommend!" —Amazon Customer
Get it from Amazon for $11.99.
17. A waffle knit linen blanket if your duvet is making you sweat but you *need* a thick blanket in order to fall asleep. This one is made from a cozy yet breathable blend of cotton and linen, so you can enjoy the weight of bed covers without overheating.
Magic Linen is a family-owned small business based in Lithuania that creates beautiful linen clothes and home products that are all Oeko-Tex certified, meaning they are free from harmful substances and chemicals.
Promising review: "I am in LOVE with my blanket. It is the perfect texture, I can wrap up in it in the summer and not get too hot, and it's so soft even after just one wash! Truly adore this blanket." —Cy D.
Get it from MagicLinen for $149+ (available in two sizes and 10 colors).
18. And a lightweight cooling blanket created with special Arc-Chill cooling fibers and a cotton backing to keep your evening routine intact all summer long. Netflix marathons just aren't the same without a blanket to snuggle with!
Promising review: "Let me start by saying I get extremely overheated when I sleep but also enjoy the weight of a blanket on me. This blanket is the perfect solution for that. It is large enough to cover my entire queen-size bed and just heavy enough to provide some weight while I sleep. It is definitely cold but not overwhelmingly cold at all. It’s like flipping your pillow over the cold side, except it’s an entire blanket! I love this thing, but I may have to get another one since my husky-mix loves it just as much as me!" —Madison Price
Get it from Amazon for $36.99+ (available in four sizes and seven colors).
19. A spacious inflatable pool so taking a dip to cool off no longer has to be a special occasion. Now every day can be a pool day!
Promising review: "Very easy to unbox and get set up. I used an electric pump (not included) and followed the easy directions. Took me only about 10 minutes to get it inflated. Then it only took me maybe an hour to fill with a garden hose. I love the drain pipe underneath that is angled away from the pool so the water is directed out of the area. But I can see that it might not be good for the pool lining if someone stepped on it from inside the pool. So I was careful to let my kids know not to step in that corner. Overall, great quality, good size (fits three full-size floaties in it!), and my kids loved it." —K M
Get it from Amazon for $64.99+ (available in two sizes).
20. A compact ultra quiet dehumidifier because the heat wouldn't be so hard to handle if everything wasn't also vaguely wet and sticky! You'll realize it's working when you take a deep breath and don't feel like you're drinking the air.
Promising review: "This is the second dehumidifier from this brand I have purchased. This one is the smaller version. I use this in my bedroom and the bigger one in my living room. I like the lights. You can choose a color or no lights at all. Nice for night-light in bedroom. Helps with helping cool my rooms." —Amazon Customer
Get it from Amazon for $45.98+ (available in two sizes and in four colors).
21. A ventilated cooling memory foam pillow with a machine washable cover for cradling your head with "cool side of the pillow" perfection all night long.
Promising review: "When these arrived I thought for sure I would return them based on the box being small! Once the seal is opened, they expand into a perfect pillow. Head and neck feel supported and stay cool. Very comfortable and good quality. I highly recommend them if you’re tossing and turning on an old pillow that doesn’t fit your comfort." —Bella's Mom
Get it from Amazon for $31.99+ (available in three sizes).
22. And a hypoallergenic 100% mulberry silk pillowcase that's chronically cool to the touch while boasting a whole host of potential beauty benefits, from protecting hair and reducing frizz to preventing wrinkles.
Celestial Silk is a woman-owned small business creating silk self-case accessories like pillow cases, face masks, and scrunchies. And the brand gives back, donating 10% of all proceeds to charity, and donating pillowcases to chemotherapy patients and lower-income women.
Promising review: "I LOVE THIS PILLOWCASE. It is so soft and comfortable. I don’t wake up with tangled hair, my skin is soft, I sleep like a rock. It stays cool at night (no cold side/hot side of the pillow) and I drift to sleep so easily. It’s like sleeping on a cloud. Eventually I’ll get a few more for all of my pillows." —sango
Get it from Amazon for $41.99+ (available in three sizes and in 24 colors).
23. A programmable AC booster fan with a programmable LCD thermostat if your central HVAC system has a weak link, resulting in uneven cooling and heating throughout your home. Install this on any existing wall or floor register to quietly increase air flow and get those internal temps back where you want them.
Promising review: "I have a room that is extremely hot in the spring and summer. With this product (and the task of temporarily closing vents in other rooms), I am able to bring the temp down 6 degrees in that hot room in just one hour without affecting the temp anywhere else! Awesome!!" —Denise Davis
Get it from Amazon for $69.99.
24. A four-pack of cooling microfiber towel to get instant heat relief in three easy steps: soak in water, wring it out, and snap! The lightweight towel can stay cool for up to three hours and comes with a convenient waterproof pouch for on-the-go storage.
Promising review: " These towels are amazing. Simply wet, wring out the excess water, and give it a good snap or two. The towel was immediately cold. I wrapped it around my neck. About 15 minutes later it had warmed up a bit. I gave it another good snap and voila. Once again it was immediately cold. I plan on using these a lot this summer, at home and on the go. The neat thing is that every towel comes with a heavy duty ziplock-type bag so you can carry the wet/damp towel anywhere and use when needed. I’m sure I’ll be ordering more of these for my family." —JeninMarquette
Get a four-pack from Amazon for $19.99 (available in 13 color combos).
25. A roll of very handy screen repair tape so tiny tears on windows and doors don't become a big, energy-wasting problem (that you eventually have to replace).
Promising review: "Does exactly what it claims to do. Easy to use, discrete. We moved into our home in late summer and didn’t notice some screen holes; getting this product allowed us to have our windows open without bugs getting in, so we didn’t have to rush into getting new window screens quite as fast. Highly recommended." —andhowe
Get it from Amazon for $9.99+ (available in black and silver-gray).
26. A temperature-controlling cube sleep system because a cooler environment can do wonders to improve your sleep. The cube interface connects with the included mattress pad, circulating water to maintain your ideal sleeping temperature.

The entire set includes: Cube control unit, Chilipad Cool Mesh mattress pad, Remote control. If you get the "We" version, you'll get two cubes and remote controls.
Promising review: "Before the sleep system I was waking up many times during the night throwing the covers off of me to stay cool. Now I sleep through the night in comfort. I didn’t know if I could really believe that it worked as well as it does but I love it." —Lanni S.
Get it from Sleepme for $649+ (available in two styles and three sizes).
27. An oscillating tower fan for anyone who thinks they don't have enough floor space to accommodate a free-standing fan — think again! This slim style is a lot more powerful than it looks with three different modes to meet all your cooling needs, day or night.
This super-quiet fan has six speeds, three modes (normal, natural, and sleep) and an additional auto mode. It also comes with a remote.
Promising review: "After moving into a traditional two story home from a rancher we wanted fans in our bedrooms to help keep them cool. I have struggled finding a ceiling fan I liked for our primary bedroom so finally decided to pick up this tower fan and give it a try. I am so impressed with how quiet it is and how much power it puts out. Having a remote is a major selling point with being in our bedroom. It’s slim and able to be tucked away into the corner out of sight when not in use, but it’s not even an eyesore that I mind having out to be seen. It was easy to assemble in a matter of just two minutes without any help needed. I’m already looking into purchasing a second one for my large family room as it has plenty of power to accommodate the space. The remote is easy to use and I am thrilled with this purchase!" —Jai Banks
Get it from Amazon for $89.99+ (also available with Wi-Fi connectivity).
28. And a high-velocity rechargeable outdoor fan if you spend most of your outside time wishing you could retreat back to the AC. Reviewers say this fan is super quiet, charges quickly, and cools shockingly well for its compact size.
It takes 2.5–3 hours to fully charge, and one charge can last from 2–18 hours depending on what speed it's running.
Promising review: "Love it. I will probably buy a second one. Easy to move around — porch, backyard, etc. Easy to recharge and will run while recharging. Like the indicator lights to let you know how much charge is left. Very quiet. Puts out plenty of breeze for a small unit. Plan to take it to the beach house with us when we go to use on the deck." —A.P.
Get it from Amazon for $169.99.
