We’re fighting fake reviews –

To determine the best water flosser, we focused on the most important features — different pressure settings, water reservoir size, ease of use, attachments, and value-added features. While we reviewed a mix of corded and cordless models, we took note of which brands offered the most water pressure settings within their respective categories as well as the water reservoir size. We considered how many attachments were included with each water flosser model, as well as any intuitive value-added features would help to improve the functionality and ease of use. If you are planning to add this device to your list of bathroom essentials, read on.

After taking all of the above into account, we selected the H2Ofloss Dental Water Flosser as our Top Pick. You’ll note that because of the modest MSRP, this is also our Best Budget choice. This at-home corded water flosser features a generous 27-ounce water reservoir, six pressure settings, and 12 multifunctional tips to support traditional flossing as well as specialized cleaning for orthodontic and periodontic needs.

  • ADA approved
  • 10 pressure settings
  • 1-minute timer & 30-second pacer
  • Not travel-friendly

When you’re working on maintaining or improving your dental health, seeing that seal of approval from the American Dental Association can give you the peace of mind that you need. This is why we’ve selected the Waterpik Aquarius WP-662 Water Flosser as our Honorable Mention. In addition to being one of the few water flossers on our list with this distinction, it also comes with a one-minute timer and a 30-second spacer feature to help you meet ADA recommendations that you floss for at least a minute per flossing period.

In addition to the above, with this Aquarius Water Flosser, you’ll enjoy a 22-ounce water reservoir and 10 pressure settings that let you cycle between 10 to 100PSI as well as toggle between floss and massage modes. With the seven flosser tips, you get three classic jet tips, one plaque seeker tip, one orthodontic tip, one periodontal tip, and one toothbrush tip.

 #3  MosPro Water Flosser

We’re sorry, this product is temporarily out of stock

Award: Best Travel

WHY WE LIKE IT: A waterproof water flosser with a 10-ounce detachable reservoir and USB charging make this ideal for maintaining your dental hygiene when you’re on the go.

  • USB rechargeable
  • 3 flossing modes
  • IPX7 waterproof rating
  • Lowest battery life of travel models
  • Lacks timer/pacer

You shouldn’t sacrifice your oral hygiene just because you’re traveling. And in particular, the last thing you want to deal with if you’re traveling is finding compatible power outlets for your charging plugs. We’ve picked the MosPro Water Flosser as the best travel-friendly option. This flosser charges via USB, meaning that you can use an external charger, your car charger, or even your laptop to recharge it. And you can expect to use this flosser for seven to 10 days before it needs to be recharged.

In addition to the above, you’ll love that this flosser is waterproof with an IPX7 rating. That means you can floss in the shower to save time. And the completely detachable water tank means you won’t deal with spills in your travel bag. Plus, you can easily clean the reservoir between uses. This model — as is standard with the travel-friendly water flossers — offers three flossing modes, four standard jet tips, and a USB cable. You can also read about the best kid’s toothpaste.

 #4  Panasonic EW-DJ10-A Cordless Dental Water Flosser

Award: Best Portable

WHY WE LIKE IT: A simplified cordless water flosser that comes with two speeds and is collapsible for storage in tight spaces.

  • Waterproof rating
  • Collapsible for easy storage in a bag
  • Cordless waterpik design
  • Only 2 flossing speeds
  • 5-oz water reservoir
  • Requires batteries

If you’re brushing and flossing after every meal this means that you need to bring your dental gear with you to work. So, you might not have the counter space to devote to some of the larger travel-friendly water flosser models on our list. In that case, the Panasonic EW-DJ10-A Cordless Dental Water Flosser is the perfect solution. The biggest draw with this water flosser is that it’s completely collapsible with a compact design that can easily fit into a backpack side pocket or a small purse.

While this model has the second smallest water reservoir (at 5.5 ounces), you still get two pressure settings. And as opposed to the other travel-friendly models on our list, Panasonic’s model relies on actual batteries instead of USB charging. But you’ll enjoy the waterproof design that makes this safe for use in the shower. Also, check out the best floss.

 #5  NiceFeel Cordless Water Flosser

Award: Best Battery Life

WHY WE LIKE IT: A long-lasting water flosser with a 20-day runtime between charges is combined with a waterproof rating and large reservoir for extended use on vacations and business trips.

  • 20-day battery life
  • 10-ounce reservoir
  • IPX7 Waterproof Rating
  • Inconsistent operation at angles

The biggest benefit of a travel-friendly flosser is that you can keep your oral hygiene intact while you’re away from home. But what sets the NiceFeel Cordless Water Flosser apart from the other travel flossers on our list is that this offers the longest battery life between charges. With a single four-hour USB charge, you can enjoy up to 20 days of flossing power before this item needs to be recharged.

With that feature aside, this model is on par with most of the other travel water flossers on our list. You’ll get four jet tip flosser heads, three pressure settings, an IPX7 waterproof rating, and a 10-ounce completely detachable water reservoir. However, as compared to some travel water flossers, the NiceFeel model comes with a carrying case for two floss heads. The best lighted makeup mirror can also help to check your teeth.

 #6  Waterpik Wp-560 Cordless Water Flosser

Award: Best Ergonomic Flosser

WHY WE LIKE IT: An easy to grip travel-friendly water flosser with the ADA Seal of Acceptance that features multiple flossing head styles and travel tote.

  • ADA approved
  • Rapid magnetic charging
  • Travel-friendly
  • Charger is clunky
  • Immobile water reservoir
  • 4-oz reservoir

We’re featuring WaterPik again, but this time with a travel-friendly cordless option. You’ll note that just like the #2 Honorable Mention choice, this model also features the ADA Seal of Acceptance. And this is because WaterPik is the only water flosser brand that has been reviewed and approved by the ADA.

While this cordless model does have the smallest reservoir (at four ounces) of the travel-friendly water flossers on our list, you still get many of the standard features seen in the travel category. This includes three pressure speeds, multiple flosser tips, a travel case for the flosser tips, and a microfiber bag to hold the base, travel case, and charging cord. You might also like the best shower caddy.

 #7  Zerhunt Cordless Water Flosser

We’re sorry, this product is temporarily out of stock

Award: Best Quality

WHY WE LIKE IT: A streamlined travel-friendly waterproof water flosser with multiple flosser tips that features an auto timer to ensure proper dental hygiene.

  • Auto timer detection
  • 10-ounce reservoir
  • IPX7 waterproof rating
  • No travel case

The Zerhunt Cordless Water Flosser is a budget-friendly portable water flosser that’s designed with travel in mind. But what sets it apart from the other travel water flossers is that it’s the only cordless flosser with a timer. It’s preset to automatically shut off after two minutes of use. Aside from this core feature, it is relatively comparable to the other cordless water flossers on our list.

You’ll like the three water pressure settings, the detachable 10-ounce reservoir, and the USB charging that can fully charge this flosser in four hours for up to 20 days of continuous use. This model comes with six detachable flosser tips — four that are standard jet tips, one dental plaque tip, and one periodontal tip. Plus this Zerhunt model features an IPX7 waterproof rating for use in the shower. Other musts for your bathroom include the best shower curtain and the best shower curtain liner.

How We Decided

It’s a known fact that most people don’t floss properly — if at all. So, water flossers can be a more efficient and thorough way of checking off an essential dental hygiene task. But there are so many options on the market. To determine the best water flossers, we look at the following criteria: pressure settings, water reservoir size, ease of use, attachments, and value-added features.

It’s important to note that if you’re concerned about buying a dental appliance and are only comfortable selecting something with an ADA seal of approval, focus solely on our #2 Honorable Mention, and #6 choices. Both are Waterpik models, and Waterpik is the only brand that is approved by the ADA for water flossing.

We started our search by looking at pressure settings. For the most part, we found that larger at-home corded models offered more pressure settings than travel-friendly options. Whereas our Top Pick and Honorable Mention models offered anywhere from six to 10 pressure settings, most of the cordless models — except for #4 — offer three pressure settings that include a gum massaging mode.

Next, we looked at the water reservoirs. By default, corded models feature significantly larger water reservoirs. Our Top Pick and Honorable Mention offer 27 and 22-ounce reservoirs respectively. In contrast, the travel-friendly cordless models ranged in reservoir size from four to 10 ounces. But specifically for the cordless models, we prioritized those with completely detachable reservoirs. Only #4 and #6 lacked a detachable reservoir. This can be an issue for some people because it will make it harder to thoroughly clean the reservoir between uses to prevent limescale or product buildup.

In terms of ease of use, all of the models on our list featured straight forward operation that makes it easy for even the most tech-averse to master. However, our #4 selection might be ideal for people who are traveling light or focus on oral care while at work or the gym. The Panasonic EW-DJ10-A Cordless Dental Water Flosser’s compact design makes it especially suited for someone with braces or aligners who is required to thoroughly floss after every meal. Likewise, all of the water flossers we featured in this guide are rated for use across a range of dental issues that include braces/aligners, bridgework, dental implants, or people with sensitive gums.

For attachments, we looked at the types of flosser tips that were included with each water flosser. At a minimum, all of the flossers come standard with multiple classic jet tips — making it ideal for shared use. But if you have specific dental needs like periodontal pocket cleaning or orthodontic cleaning around braces, focus on our #1, #2, and #7. The remaining models (#3, #4, #5, and #6) only come with multiple classic jet tips.

And finally we looked at value-added features. This included options like a timer/spacer (#2 & #7), USB charging (#3, #5, and #7), waterproof rating (#3, #4, #5, #6, and #7), and travel cases or totes (#5 and #6).

Another popular choice that just missed our list was the Philips Sonicare AirFloss. The Sonicare AirFloss cleans your entire mouth in 30 seconds and removes up to 5X more plaque than a manual toothbrush alone. However, the Sonicare AirFloss is not an oral irrigator and does not use water to flush throughout the mouth.

Water Flosser Buyer’s Guide

The Most Important Features to Consider

  1. Water Pressure
    If you hate traditional flossing because you think it’s too cumbersome, then water flossing can be a great, faster alternative. Water pressure is going to be one of the most important features you need to consider as low water pressure won’t properly remove debris or plaque from between teeth and along the gumline. Likewise, a pressure that’s too intense can hurt your gums. Most water flossers come with adjustable water pressure settings. Usually, you’ll have at least three settings, but some offer as many as 10 with a range from 10 to 100 PSI. Typically corded water flossers offer stronger pressure than cordless models.
  2. Power Source
    Water flossers are available in corded and battery-powered versions. There are benefits and drawbacks to both. Like we mentioned earlier, corded models tend to feature higher water pressure settings. But a rechargeable model is ideal if you want to take your flosser with you when you travel and don’t want to deal with power outlet compatibility.
  3. Water Reservoir Size
    It’s important to look for a water flosser with a large reservoir tank. The biggest benefit to this is that it’ll limit the number of times you need to refill your tank while flossing your teeth. Cordless models understandably have smaller tanks with a maximum capacity of typically seven ounces. In contrast, corded models with a countertop base feature larger reservoirs as big as 35 ounces.
  4. Design for Multiple Users
    If you’re not the only person in your house who plans to use a water flosser then you need to focus on hygiene. You want to look for a water flosser model that comes standard with multiple floss heads. Ideally, each floss head will feature a color ring to help differentiate everyone’s unique floss tip. Likewise, you want to look for models with a tip ejection button so you can quickly and easily switch out floss tips.
  5. Value-added Features
    A basic water flosser will come with a water reservoir, ejection tip button, and multiple speed settings. But you might want a model that offers enhanced functionality such as a timer or pacer, or a massage mode. The massage mode is ideal for those focused on their gum health. Timers and pacers ensure that you’re flossing thoroughly. Some will vibrate or emit a sound when you should switch between regions of your mouth or when you’ve reached the recommended flossing timeline. Additionally, some models give you the ability to pause water flow without completely powering off the water flosser.
  6. Ease of Use
    Flossing can be difficult when you’re trying to access hard to reach areas of your mouth like your back molars. To make this process easier, look for water flossers that feature a swivel water hose or offer rotating tip control so that you can floss more efficiently in the back of your mouth. It should be as easy to use as the best electric shaver.

Water Flosser FAQs

Are water flossers better for me than traditional string floss?

Truthfully the answer is no. While water flossers can make the flossing process easier, most dental professionals recommend that you start with traditional/regular floss and then follow up with a water flosser to help remove bigger particles. However, it’s important to note that most dental professionals would rather that you use the method you find easiest that helps you make flossing a daily habit.

I find it hard to floss properly with traditional floss, how will a water flosser be better for me?

Most people don’t realize that with traditional flossing, you’re supposed to follow a C-shaped pattern along the gumline and between teeth. So, if you don’t use the proper technique with dental floss, you could still find yourself with plaque buildup or cavities at your next checkup. A water flosser relies on water pressure to gently yet effectively remove plaque and debris from the gum line and between teeth. So as long as you move in a scallop pattern along the gumline and between your teeth, it’s very hard to make a mistake with a water flosser.

I’ve never used a water flosser, what should I expect?

One of the biggest learning curves with water flossers is adjusting to the water pressure. Most models offer a “soft” or low setting that has a lower pressure and gives your mouth a chance to get acclimated to the feeling of the water pressure against your gum line. As your mouth gets accustomed to the pressure, you can slowly increase the settings. Also, make sure you check the water reservoir capacity. Smaller models might only offer 30-60 seconds of water capacity, while larger models will offer over 90 seconds of water capacity.
