We already spend a bunch of money on tech, so why not invest some of it in drinking quality water, the vital liquid we literally can’t live without? As the summer gets hotter, we need to stay hydrated, especially if you’re about to enjoy the warm summer days with the family and guests.

Have you seen the prices on those fancy water filters, though? They can get quite expensive, but Waterdrop Filter is jumping into Prime Day with both feet, offering some of the best deals on the market. Which model you pick will depend on your needs, so let’s go over each offer and show you which best suits you.

Waterdrop X16: The ultimate water filter for large families and parties

Do you need a real performer? The Waterdrop X16 is an alkaline-mineral reverse osmosis system recommended for large families of 6 or more people. You can keep your family hydrated with premium, healthy water, and quench your guests’ thirst during your next BBQ, game day, or party. It will handle all your drinking, cooking, and hosting needs without much effort.

This undersink filter can process up to 1,600 GPD (gallons per day), so you can be sure it will keep up with any home gathering, as well as your daily consumption. It’s also pretty quick, as it can fill a 6-oz cup with water in just two seconds.

The 11-stage reverse osmosis filtration system will also keep water healthier and tasting better. It effectively reduces TDS, PFOA, PFOS, Chlorine, Fluoride, Arsenic, Lead, and more. Not only will it clean your water, but it will also add minerals to improve your family’s general health.

While very capable, the Waterdrop X16 is designed for self-installation, so it requires no expert installation or complex kitchen modifications. Of course, you can have a plumber help if you don’t feel confident enough, but a bunch of Amazon reviews mention the process is a breeze.

Waterdrop G3P800: The best bang for the buck for large families!

As amazing as the Waterdrop X16 is, it is overkill for most people’s needs. The Waterdrop G3P800 is still a great solution for families of 4-5 members, and the MSRP is cut in half! Not to mention, today’s 30% Prime Day discount will bring the cost down to just $699.

The 10-stage filtration system can remove PFAS, fluoride, lead, chromium, iron, nitrate, chloride, and even radioactive substances like radium. It’s also certified against NSF/ANSI 42, 53, 58, and 372 standards, so you can be sure your family and friends will be safe.

The G3P800 can still filter up to 800 GPD. While that’s half the price of the premium model, it’s more than enough to meet most home needs. I mean, 800 gallons per day is quite a bit of water! And the smart faucet can fill a cup of water in five seconds.

Waterdrop G5P700A: For mid-sized families with more moderate needs

Great water quality doesn’t need to be expensive. The Waterdrop G5P700A makes reverse osmosis filtering much more accessible with a $359.99 retail price, and Prime Day is bringing the cost down to just $275.49.

While much simpler, it is still great at keeping your water healthy and tasty. The 8-stage filter removes PFOA, PFOS, chlorine, bad taste and odor, lead, fluoride, heavy metals, and other impurities. Of course, it also adds minerals to keep you healthier.

This one can filter up to 700 gallons per day. I mean, I feel like that is still much more than I would ever need! It is a bit slower, as it can fill a 6-oz cup in six seconds, but I feel like waiting an extra second or two is fine, especially if you’re saving this much money. It’s also a very convenient system thanks to the Waterdrop G5P700A RO support. It can directly connect to ice makers, fridges, and other water devices.

Waterdrop M6H: For those who can’t permanently install a system

The options above are great for homeowners, but many of us rent and can’t permanently install these systems. And even if you can, I prefer simpler solutions. Not to mention, you might want it for a small space, an office, a room, etc. That’s when the Waterdrop M6H shines!

The M6H is honestly the perfect solution for me. It’s a countertop filtration system that requires no installation. Just place it on a flat surface, set it up, and get drinking!

This one has a simpler 7-stage filtration system, but it still takes care of the most important contaminants. These include TDS, PFOA, PFOS, Nitrate, Fluoride, Arsenic, Lead, and more.

Just keep in mind that its limited size will also mean reduced performance. For example, the tap water pitcher can only hold 185 ounces of water, and 50 ounces are dedicated to wastewater, so you will have to keep refilling it.

It has some really cool features, though. For starters, there’s a 40-oz pitcher for your convenience. It’s detachable, so you can take it to a table or outside, or keep it cool in a fridge. Also, it can heat the water up to 203 degrees Fahrenheit. Want some tea? You got it! It even has an NFC chip that will lead you to guides and other information about your water filter.

Which of these are you getting? I am liking the idea of the Waterdrop M6H, as I live alone in a small cabin. I can drink healthier water, and it more than meets my needs. It would also be great for people in dorms, small apartments, a small office, etc.

That said, there is something here for everyone’s needs. Get ready for healthier water before the deal ends. You might want to be quick, because these promotions will only run for a few days, from June 23-26, 2026. The offers will be available from Amazon and Waterdrop’s official site.
