If you think that the only way to floss your teeth is with a bit of string, then you are completely wrong. If you get the best cordless water flosser, you can keep your teeth nice and clean, without any of the discomforts of standard flossing. Of course, not all water flossers are created equally, so you need to have a good idea of what you are looking for before you make your final purchase.
For starters, you need to make sure that you find a model that has enough pressure to get in between your teeth. We have also looked for flossers with large water reservoirs so that you won’t need to constantly refill them. You will also have to decide on whether or not you want a flosser with just one pressure setting or multiple ones to better suit all of the folks that live in your home. Even if you are completely new to the world of water flossers, don’t worry, we will guide you through everything you need to know to find the best model for your needs!
If you are in the market for the best overall water flosser, then this is the machine we recommend you check into first. It is a very user-friendly model, making it good for both first-time users and anyone that has used a water flosser before. This model comes equipped with three different pressure levels, which will allow you to choose from 30 PSI up to 100 PSI. This wide range will make it much easier to get used to using the flosser correctly if you are new to it, while still providing enough power to really clean your teeth.
Why did it make our list? This flosser also has a long battery life. It can be used for up to 10 days on a single charge, even if a bunch of people is using it. It comes with four different nozzles, which makes it great for a family to use. This model also has a high-capacity reservoir, so you should have no trouble flossing your teeth quickly and efficiently.
What is not ideal about it? The only real downside to this otherwise phenomenal water flosser is its power button. It is, unfortunately, a bit sensitive. Basically, it is too easy to turn on. While this might not seem like all that big of a deal, it makes it a lot easier to accidentally spray water all over your bathroom, which is, obviously, not ideal. Of course, as long as you are very careful not to bump the button at all until you are ready to use it, you shouldn’t have too much of a problem utilizing this flosser effectively.
One of the biggest issues that come with portable electronic devices is that they need to be charged. While this might not be too big of a deal if you regularly remember to plug it in, this can be a huge problem if you are running late. If that is a concern for you, then this is a good option. This flosser only takes about 4 hours to fully charge. While that might seem a bit too long, it can actually be charged for single-use in only about 15 minutes, which is more than enough time to get quick flossing in before bed.
What stands out? A big positive for this flosser is that it comes with five different nozzles, making it a great purchase for a larger household, or anyone looking for a value-based purchase. This unit has 4 different pressure settings, which will allow you to find the right mode to suit your mouth’s needs.
Even though this is a smaller and more portable model, it still has plenty of water capacity. It can provide up to 60 seconds of flossing, which is quite high for a portable flosser. The display is also quite easy to read, making it very simple to find the right mode each and every time.
What cons did we manage to find? The one thing that we didn’t quite like with this model is its tip storage. While it is very nice that the company has provided something to hold the tips, it is not terribly easy to use. The tips need to be fitted in just the right way. Otherwise, they fall out quite easily. Thankfully, with a bit of practice, you should be able to solve the intricacies of this storage tool and use it effectively.
What really helps to set this model apart from its competitors is the style and design of that it enjoys. This is a sleek and compact water flosser that is built to not only work extremely well but also to look good while it is sitting in your bathroom. While many water flossers have a very medical aesthetic, this model will fit right in with your bathroom décor with ease.
What are our favorite features? The flosser boasts of three different pressure settings. Each one is just enough pressure to remove all the grime from your teeth each and every time, while still remaining gentle enough to keep you coming back for more.
This unit also comes equipped with 4 different nozzles, which makes it a great buy for anyone with a larger household. These tips are also quite easy to store, thanks to the carrying case and nozzle storage that is provided with the flosser. This carrier is well designed, which makes placing and removing the nozzles nice and easy.
What could be better? Though this model charges very quickly, the charge doesn’t last very long. While this shouldn’t pose too big of a problem if you keep it plugged in all of the time, it might cause some consternation if you are taking it on vacation and have more than one stop on your journey. If you forget to plug it in one night, the odds are that the battery will be dry the next day when you go to use it, so make sure you plug this model in right away if you do choose to purchase it.
There is a lot to like with this water flosser, but perhaps its best feature is its high capacity water reservoir. Of all the different models that we looked into, this unit has, by far, the longest runtime out there. With this unit, you can easily get up to 80 seconds of flossing time, which should be just enough to get all of your mouth done. This will limit the amount of time you need to spend refilling your flosser, which is a huge time saver.
Why are we impressed? This model also comes equipped with a wide array of nozzles and tips. It comes with 6 different nozzles which can be used to floss, and then two brushes to actually brush your teeth. This is a great value since it will allow you to not only replace standard floss at your sink but your old toothbrush as well.
With this flosser, you can also choose from 5 different pressure settings. This variety makes it easy to find the right pressure for your mouth while also allowing anyone else in your household to find the right setting for their needs.
What negatives must you be aware of? Though the designers thought of lots of things for this water flosser, they didn’t include a very necessary piece of the puzzle: the charger adapter. While this model comes with a charging cord, it doesn’t come with the adapter to plug into the wall. Of course, while most folks probably have a charger that can be used to plug into the cord and wall, you might need to make an additional purchase to keep this flosser charged and ready.
Even though many of the water flossers we checked out came with some sort of a carrying case, none of them make packing up and taking the flosser along quite as easy as this one. Many cases are just big enough for the nozzles and flosser to fit, which makes getting them in correctly a tricky job. That is, thankfully, not the case for this model. The case is quite voluminous, which makes fitting all of the pieces in place quick and easy.
Why did it make our list? This unit comes equipped with four different nozzles, all of which fit into the carrying case with ease. These nozzles are all the exact same, which makes this a great value for a solo user and also a great buy for any family that is looking for a new water flosser.
This machine is also a good balance between a quick charging time and a long battery life. With this flosser, you can expect it to last several days on a single charge, even though it only takes about 12 hours to get to a full charge.
What is not ideal about it? Something that we didn’t like with this model is the fact that it has a very low water capacity. While its smaller water reservoir makes it easier to pack up and take with you, it will also necessitate several refills before you are done flossing your teeth. With this reservoir, you can only get about 45 seconds of use before you need to refill, which is not nearly enough to effectively floss your teeth.
This flosser is quite good for someone that is new to using a water pick. It only comes equipped with one pressure setting, which makes it very easy to pick up and use. The pressure level is not too high either, which will make it much more comfortable for someone that is just learning how to use this style of flosser effectively.
What makes it special? The first thing that will pop out at you with this model is its battery life. On a single charge, you can expect it to last up to 3 weeks. This is the longest battery life of all the different flossers we reviewed, making it a great option for anyone that goes on long vacations. You could conceivably charge this flosser before you go on a week’s vacation and not even have to bring the charger along with you at all.
Surprisingly, even though this flosser is quite compact, it still has a pretty high water capacity. You can easily get 60 seconds of use out of one reservoir, which is probably enough for half of your mouth.
What cons did we find? Though we absolutely love the long runtime for this model, it is a bit of a double-edged sword. With its higher capacity battery, it should not be a big surprise that it takes so long to fully charge. It is still a bit of a hassle, however, that you need to wait for a whole day to pass before the battery is full. That means that you will need to make sure to plug this flosser in often so that it will be able to last as long as possible.
When you hear the term “water flosser” an extremely sophisticated piece of equipment probably comes up in your mind. With sophistication comes expense, at least normally. That is, fortunately, not the case for this unit. It is quite inexpensive, even though it has its share of innovative designs. For instance, it is collapsible. This design makes it very easy to travel with since it barely takes up any room at all.
What are its best features? Something you don’t expect to see in a value-based model is two different pressure settings. The higher setting is quite powerful and can get up to 1,400 pulses per minute. Even though this flosser is not terribly expensive, you can still get more or less pressure on your teeth based on your preferences.
This model also has pretty long battery life. While the charging process can take up to 15 hours to get a full charge, it is well worth it. Once the flosser is fully charged, you can expect it to last about a week before it needs to be charged again.
What could be improved? The biggest issue with this smaller than average water flosser is its reservoir capacity. It can only last about forty seconds before it will need to be refilled, which could mean that you will need to fill it at least three times before you get your mouth completely flossed. While this might not be a big deal if time is on your side, you certainly don’t want to have this number of refills if you are in a hurry.
Things to Consider
In this section, we will go through all of the ins and outs of finding the best cordless water flosser for your money. We have also taken the time to answer some frequently asked questions, so be sure to read through those as well if you need any more information.
Why you need a water flosser
Now, you might be asking yourself: Do I really need one of these flossers? Couldn’t I just get by with standard floss? The simplest answer is, of course, no! These flossers offer a variety of advantages over standard flosses, such as:
Easy to Use – Unlike standard floss, which can be a bit tricky to use correctly without causing discomfort, a water flosser is very simple to use. You simply find the pressure and pulsation levels that feel best for you and allow the flosser to do the work. By guiding it along with your teeth and gum line, you will easily and effectively remove plaque, bacteria, and any food that might be stuck in no time at all. Refilling and charging is also a cinch, thanks to the built-in water reservoirs and dedicated charging stations.
Highly Effective – As we mentioned above, not only are these flossers easy to use, but they are also highly effective. Through careful research, dentists have determined that these flossers are much better than regular string floss. They are able to reach deeper between teeth, which helps to keep them even cleaner. This is especially true for anyone with tight teeth or a younger person who is wearing braces.
Gentler than Standard Floss – One of the biggest reasons that folks don’t floss their teeth is because they do not like the way that it feels. If they are someone that has tighter teeth, it can be downright painful to floss with string. A water flosser, on the other hand, is extremely gentle. It feels more like a massage for your mouth than a cleaning tool, making it perfect for anyone with a sensitive mouth.
Reusable – While string floss is not terribly expensive, it isn’t free either. By buying a water flosser, you will save yourself a bit of money over its lifetime, simply because you won’t need to buy a new one anytime soon. You can use it every day with ease, which is a big difference from string floss, which can only be used once and then needs to be discarded.
Features to consider when choosing a cordless water flosser
Odds are that you have never had a water flosser before. Even if you have, they have changed so much over the years with new technology making them more effective. In this section, we will guide you through all of the important features to factor into your purchase so that you can get the best model to help keep your mouth healthy and clean.
Pressure range and number of settings
The very first thing that you will want to check into is the pressure range and, depending on which way you go, how many pressure settings you need. There are two basic categories that water flossers fall into in this regard.
One Pressure Setting Models – This type of flosser, like the Philips Sonicare AirFloss, are perfect for a first-time buyer. They only offer one pressure setting, so there is no fooling with different pressures. This makes them straightforward and easy to use. Of course, this does limit their effectiveness, especially if they don’t have enough pressure for your needs, or they are being used by more than one person.
Multiple Pressure Setting Models – If this is not your first water flosser, then you might want to go for a multiple pressure setting model. These flossers, like the MOSPRO Water Flosser, offer different pressure settings so that you can find the one that works best for you. It will also allow you to use different levels on different parts of your mouth, depending on far apart your teeth are. You can also get a model like the BESTOPE Water Flosser, which comes with multiple tips to make it so everyone in the family can use the flosser safely.
Nothing is worse for your morning or nighttime routine than finding an item you need, be it a cordless water flosser, brush, or shaver, is out of battery. As such, it makes sense to look into how long it takes to charge your new flosser before it can be used to clean your teeth. That way, you can find the one that will work best with your routine.
If you are someone that is always on the go and might forget to properly dock your flosser between uses, then you will probably want to get something like the Liberex Cordless Water Flosser. This machine only takes about 4 hours to fully charge. This means that it can get enough charge for a quick cleaning session in about 15 minutes, making it ideal for someone that leads a busier lifestyle. If you are aren’t worried about having to do a quick charge, then the Panasonic EW-DJ10-A is a fine option, even though it can take up to 15 hours to charge fully.
Something else that should factor into your decision is how long the battery will last after you have it charged up all of the ways. Models that typically take the longest to charge will also have the longest battery life. Quick charging models will need to be recharged more often since they usually have smaller batteries.
If you are looking for the longest battery life on the market today, then the MOSPRO Water Flosser and the Philips Sonicare AirFloss are your best bets. Each model can last up to a week on a single charge, with the Philips able to be stretched for up to three weeks between charging sessions. This makes it a great option to take with you when you are traveling, since you could, conceivably, take it along without bringing the charger along with you.
Another feature to consider carefully is how much water capacity you need. You also need to understand that water capacity for a cordless flosser is measured differently than other appliances. Instead of relying on standard measurements, the capacity of a flosser is how long you can utilize it before it needs to be refilled. The larger the capacity, the longer the cleaning time you will have before it runs out of water.
The standard capacity for most water flossers is about 60 seconds. If you need more time than this, then we recommend that you check out the BESTOPE Water Flosser. It has a larger water reservoir, which allows it to last a bit longer than all other models. With this water flosser, you will get about 80 seconds worth of capacity to conduct your cleaning, which should be more than enough time to get your teeth bright and clean.
Some models of water flossers come with multiple nozzles. These nozzles might be the exact same or offer some other type of functionality.
Having multiple nozzles is especially helpful if you have more than one person that is going to be using the flosser. That way, everyone can have their own nozzle. This will help to keep the flosser cleaner and will also help to keep all of the users from spreading germs amongst each other.
If you simply want a flosser that comes with multiple tips that are all the same, then the Waterpik WP-563 is a good option. It comes with four different heads that can be used by multiple family members. The BESTOPE Water Flosser comes with different types of nozzles, which adds a bit of versatility to the unit, so you might want to consider that as well. Of course, you could always just go with something like the Panasonic EW-DJ10-A if you want to save yourself a bit of money and only need one nozzle anyways.
While the dimensions of your new water flosser shouldn’t be the biggest concern, it is still something that you should take into account. The last thing that you want to do is buy a model that is a bit larger and try to find counter space for it in your smaller bathroom. Larger models are also more difficult to travel with, which could be an issue if you want to bring your flosser along on vacation.
If you are looking to keep your flosser as small as possible, then the Philips Sonicare AirFloss is a good bet. It is built to be extremely slim, which makes it much easier to fit onto a crowded countertop. Of course, this does limit its capacity a bit, so you need to bear that in mind as well.
Aside from the standard features that you need to choose from, there are also several different options out there that you might want to consider. One of these is a very simple item but can be extremely useful, especially if you are taking your flosser with you. We are speaking of a travel bag, of course. These bags will help you to keep your flosser and all of its components well-organized and safe while you are on the go, which is, obviously, ideal.
Something else that might make traveling a bit easier is the collapsible design of the Panasonic EW-DJ10-A. Since this brush can be made to be a bit smaller than it usually is, it can fit into a bag much easier as well.
Some models also can be equipped with brush heads as well, which is a great innovation. Not only does it allow you to keep your gumline clean, but it will also help you to keep the rest of your teeth sparklingly bright as well. This is also a great way to lighten your load while traveling or on your countertop as well since it will allow you to only take one thing along with you rather than two.
How to sanitize it?
There are several steps that you should follow if you want to keep your water flosser operating correctly and cleanly. These include the following:
Clean the Outside – This is the easiest part to clean. You can simply wipe it down with a soft cloth and some soap to keep it looking good.
Clean the Reservoir – Every few weeks, you should deep clean the rest of your flosser. This starts with the reservoir, which should be removed and washed in warm soapy water. Once you have given it a good scrubbing, rinse out the soap and allow it to air dry.
Clean the Internal Parts – After the reservoir is clean, mix a solution of 2 parts water to white vinegar and place it into the reservoir. Run this mixture through the flosser. Then, flush the system by running clean, warm water through it as well.
Clean the Handle – Remove the nozzle and place the handle into a cup of 2 parts water and 1-part white vinegar for 5 minutes. After it has been removed, rinse the handle under warm water and allow it to air dry.
Clean the Nozzle – Using the same type of mixture as you did for the handle, place the nozzle in, and allow it to soak for 5 minutes. Then, rinse it with warm water and allow it to air dry. Remember to replace your tips every 6 months so that they work effectively.
When you are using a water flosser, you need to be careful to take your time. Just as when you are brushing your teeth, the faster that you go, the more that you are likely to miss. This is, clearly, less than ideal and should be avoided if possible. As such, you should make sure to use your flosser for about 2 total minutes, or more if necessary. This works out to about 1 minute for the top and 1 minute for the bottom of your mouth to get it completely clean.
A water flosser does not need to be used twice a day. The current guidance from the dentists is that you should brush your teeth at least twice a day and floss once. Of course, you can use the flosser twice a day if you wish, but it is not necessary. If you only floss once a day, you should make sure that it is right before you go to bed. That way, you can clean off everything that might be stuck on your teeth from the day, and go to bed with a completely clean mouth.
Of all the different water flossers we reviewed for this article, we have found that the MOSPRO Water Flosser is far and away the best one available. It has a long battery life, comes with plenty of nozzles, and has multiple pressure settings. Add in the fact that it has a high-capacity reservoir, and you can easily see why we recommend it so highly!
The Liberex Cordless Water Flosser is a very quick-charging model. It can easily be charged within a few minutes for a quick flossing session, or 4 hours to fully charge it. This makes it a great option for anyone that lives a busy lifestyle.
The Waterpik WP-563 is the best cordless water flosser if you are looking for lots of premium features. This model charges quickly, has a well-designed carrying case, and is aesthetically pleasing, making it a welcome addition to any bathroom.
