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 up to 16 hours to make sure your air stays humid all night. 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

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 can 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

This little diffuser—seriously, it’s only slightly bigger than an iPhone—can spread your favorite essential oil scent through your home. Fill it with water and a few drops of your favorite essential oil and it's ready to diffuse. 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 can control. 

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!

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 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 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 won't stain the tub.

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 scroll through apps. 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.

What to Look for in an Amazon Product

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.
