Shopping on Amazon can be downright dizzying. The site has so many products for pretty much any and everything. It's always great to have options, but the sheer number of products can also make narrowing down your choices pretty tough.

To make shopping a bit easier, we selected the best-selling products on Amazon. 

Best for Winter Blahs: Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier

This small, quiet humidifier includes a 1.5-liter tank that lasts through the night — up to 16 hours — to make sure you don’t wake up with dry eyes and a scratchy throat. It’s light and compact, so you can easily move it from room to room or take it on a trip. And the nightlight makes it perfect for a kid’s room or nursery.

Best for Quick Messes: BLACK+DECKER Dustbuster Handheld Vacuum

BLACK + DECKER CHV1410L 16V Cordless Lithium Hand Vac

No matter how much you seem to charge them, handheld vacuums tend to die after you’ve cleaned up only half your mess. But this vacuum works continuously for much longer and it has surprisingly strong suction. It also comes with a crevice-cleaning attachment and has a translucent, bagless dirt bowl that allows you to clearly see when it needs to be emptied.

Best for Peaceful Sleep: Mellanni Bed Sheet Set

Mellanni Bed Sheet Set - Brushed Microfiber 1800 Bedding - Wrinkle, Fade, Stain Resistant - Hypoallergenic - 4 Piece (Queen, White)

These Mellanni Bed Sheets aren’t your typical sheets — they’re super soft, barely take up any room in a hamper, dry quickly and feel cozy yet cool at night. They’re magical and somehow still cost under $35 for a four-piece set.

Best for LOL Fun: What Do You Meme Adult Party Game

Very Good

Think you make better memes than your friends? Get a healthy competition going with this adult party game. Players match popular memes’ photos with over-the-top caption cards to create the funniest combos. Think of it as a version of Cards Against Humanity with ridiculous photos. But fair warning: Don’t invite your grandma to the game. You may be permanently embarrassed when she has to read your R-rated caption.

Best for Easy Wake Ups: Philips SmartSleep Wake-Up Light with Colored Sunrise Simulation

Alarms jolt you out of bed, but this unique light gradually wakes you up by simulating the sunrise. About 40 minutes before your alarm, the light slowly starts to brighten from dark orange to white. You can also turn on one of five nature-inspired sounds. Why not make getting out of bed an experience you actually look forward to every day?

Best for Instagrammers: Fujifilm Instax Mini 9

Fujifilm Instax

Get ready for some Polaroid nostalgia. This cute camera prints your photos right after you take them. It has a close-up lens attachment and a dial that lets you adjust the brightness — a feature that’s great for party portraits. And, of course, the Instax Mini 9 comes with a mirror in the front to help you capture the perfect selfie.

Best for Quiet Nights: Homedics White Noise Sound Machine

Once you start being a believer in the power of a white noise machine, you won’t be able to live without one. This model has six sound choices — both white noise and nature sounds — that help you fall asleep or tune out distractions when you need to focus. The machine is so small that you can fit it in a purse to take it on the go!

Best for a Spa Like Home: URPOWER Essential Oil Diffuser

Very Good

This little diffuser — seriously, it’s slightly bigger than an iPhone — makes your house smell good and helps you breathe easier. Fill it with water and a few drops of your favorite essential oil to get rid of dry air. You can keep yours on continuously or set it to turn off and on (for 30 seconds each) until it runs out of water hours later. Bonus: it lights up in seven different colors that you control to match your mood. 

Best for Quick Dinners: Instant Pot Duo 7-in-1 Electric Pressure Cooker

Instant Pot DUO60 6 Qt 7-in-1 Pressure Cooker

The Internet is obsessed with the Instant Pot. It looks like a typical countertop rice cooker, but it has magical powers that allow you to cook almost any meal you can think of. Replace your pots and pans, pressure cooker, steamer and rice cooker with just this tiny appliance. (We’re all for less clutter.) You can even make yogurt in your Instant Pot. And cakes!

Best for Being Heard: Amazon Echo Dot (3rd Gen)

Amazon Echo Dot (3rd Gen)

This voice-controlled assistant will tell you the weather, play music, help you in the kitchen and even order you an Uber. You can Google anything from across the room or send a message to a friend without touching your phone. Hopefully, the technology will be good enough for you to someday say, “Alexa, do my laundry.” We can dream.

Best for Classic Cooking: Lodge Pre-Seasoned Cast-Iron Skillet

Despite the name, pre-seasoned cookware has nothing to do with spices. Cast-iron skillets need to be seasoned — meaning vegetable oil is baked into the pores of the metal — to create a nonstick surface and prevent them from rusting. Usually, you have to go through the whole seasoning process at home, but Lodge just saved you all the work. This durable pan is ready to use right out of the box.

Best for a Zen Life: Himalayan Glow Himalayan Pink Salt Lamp

Some people believe that Himalayan salt lamps release negative ions that purify the air. We believe that these lamps look stunning wherever you put them. Whatever side you fall on, you can’t go wrong by having a lamp or two in your favorite room. The lamps are made of real pink salt to create a relaxing glow that sets the mood.

Best for Glowing Skin: TruSkin Naturals Vitamin C Serum

TruSkin Vitamin C Serum

Shake up your beauty routine by adding in this vitamin C serum. You can even wear it under your makeup. It evens out skin tone, reduces acne, fades dark spots and smoothes out skin. Plus, using the serum in combination with your daily sunscreen helps you block more of the sun’s rays.

Best for Germaphobes: SafeRest Hypoallergenic Waterproof Mattress Protector

Protect your mattress from spills, dust, allergens and bacteria with this thin cotton terry cover. And unlike other mattress covers, this one is quiet — not squeaky — and keeps your bed cool and dry.

Best for Juice Bar Addicts: NutriBullet High Speed Blender

Don’t spend $5 on your daily smoothie when you could easily make your own every morning. The NutriBullet blender is tiny but powerful. It pulverizes tough fruits and vegetables to create a silky smooth drink in minutes. The cleanup process is usually where blenders fail, but this one rinses out quickly. Once you get it, you won’t have any more excuses to dodge breakfast or miss out on your daily quota of vitamins and minerals.

Best for At-Home Spa Days: Aztec Secret Indian Healing Clay

Aztec Secret – Indian Healing Clay

Use this well-known container of bentonite clay — sourced from Death Valley — to make your skin feel smoother and potentially clear up acne. Many fans of this product make a face mask by mixing the clay powder and apple cider vinegar. This combo has a more balanced pH and cleans dirt deep from your pores.

Best for Bath Time Fun: Crayola Color Bath Dropz

These Crayola color tablets make bath time so much more fun (even for adults!). They quickly dissolve to transform your bath into colorful, fizzy water. Mix and match the colors or create a rainbow all at once. Kids love experimenting with the different color combinations, while adults use them to relax in spa-like, crystal-blue water. And, luckily, the dyes never stain the tub.

Best for Partiers: Frigidaire Igloo Countertop Compact Ice Maker

This countertop ice maker can make up to 26 pounds of ice every 24 hours. Just push the button to choose your cube size and you’ll have ice ready in six minutes. The sleek stainless steel finish looks great in your kitchen and there’s even a clear viewing window that lets you check in on your ice. Get one if you throw a lot of parties or want to feel super luxe on your next camping trip.

Best for Health Nuts: Hydro Flask Standard Mouth Water Bottle

Hydro Flask

This is the only water bottle you’ll ever need. It holds a lot (either 32 or 40 ounces, depending on the size) and comes with a BPA-free, wide-mouth lid that has a built-in straw. The double-wall vacuum insulation keeps liquids icy cold for up to 24 hours and piping hot for up to six hours. Can you say that about your current water bottle?

Best for the Accident Prone: PopSockets Expanding Grip

If you’re that person who always has a horrendously cracked phone screen, then prevent that next phone drop by getting a PopSocket. This ingenious grip sticks to the back of your phone to help you hold it while you text or surf the Web. It stays put but doesn’t leave a residue if you take it off. It also doubles as a stand when you want to prop up your phone to watch videos.

Best for Noisy Commutes: cowin E7 Active Noise Cancelling Bluetooth Over-Ear Headphones

These noise-canceling headphones let you actually hear your music clearly in a bustling environment. They’re perfect for city dwellers, frequent travelers and people who wear headphones in a loud workplace. The Bluetooth connection means there’s no cord that tethers you to a device and the battery lasts for up to 30 hours. Plus, the headphones have a button that lets you control the volume, switch your playlist or take a call.

Best for Outdoorsy Folk: Venture Pal Lightweight Hiking Backpack

This super light backpack — it weighs less than a pound — gives your sore shoulders a break during your next hike or day trip. It has breathable material, padded shoulder straps and five pockets to keep your things organized. The backpack also folds up into its own pocket for storage, so you can take it on a trip and avoid those extra baggage fees.

How We Tested

We bought seven of our readers’ favorite best-selling Amazon products and our reviewers tested them for more than 100 hours. We asked our testers to consider the most important features when using these products, from their usefulness to their quality. We’ve outlined the key takeaways here so that you, too, know what to look for when shopping.

What to Look for in Amazon Products

Usefulness The best purchases and gifts are those that make you wonder how you ever survived without them. While some unique, quirky products can be fun once in a while, it’s those that are useful that end up being the best purchases and won’t end up in the giveaway pile during that Marie Kondo-inspired cleaning binge.

Quality There’s nothing worse than a great product that breaks shortly after you purchase it, or one that you can tell is shoddily made right out of the box. Of course, you can usually return them, but it’s a hassle. So evaluating products for quality before you buy saves a significant amount of time and headaches.

Customer feedback While not everyone will agree on everything, hearing how other people who purchased the products liked them and what their experiences with them have been is invaluable. Trustworthy online reviews are incredibly helpful to hone in on a product’s qualities — both positive and negative. They’re the next best thing to actually trying the product out yourself.
