Perhaps the best feature of the H2oFloss Professional Countertop Water Flosser is how quiet it runs. A close second is the oversized water tank that allows you to floss for several minutes without losing pressure. Users will also appreciate the smart tip storage with cover that protects tips from exposure to dust and germs — we certainly did during our testing.

What experts liked
The other differentiating features that make this product stand out from its competitors is the number of water-flossing tips, which this unit has plenty, including jet, tongue cleaning, orthodontic, periodontal, and even nasal tips.
- Gadgets
The powerful pulsating water pressure is one of the most impressive things about the H2ofloss Countertop Water Flosser. Pulsating water removes food debris, bacteria, and plaque much easier and more effortlessly than single-steam water pressure.
- Wise Pick
Large water capacity – over 2 minutes of flossing time at full pressure
- The Toothsayer
One of the best features of the H2ofloss Countertop Oral Irrigator is its powerful, pulsating water pressure. Pulsating water dislodges plaque, food debris, and bacteria easier than single-stream pressure and makes it easier to achieve that total mouth clean you’re looking for.
It comes with five pressure settings you can switch between and 12 different tips that can be used for cleaning safely and effectively around your implants and your entire mouth.

It has a large water capacity and fits nicely in a small space. In my opinion, it surpasses the leading competitor!
- Best Advisor
Extremely quiet operation. The h2ofloss hf-8 water flosser is extremely quiet during operation, registering around only about 50 decibels of noise when powered on. Many users report being surprised at how quiet the water flosser operates. Having a water flosser with such quiet operation makes using this model more comfortable than other water flossers.
- Review Lab
The irrigator includes an extra-large water tank which holds up to 800ml plus a side tip holder with an inner plastic slot that enables simple tip removal and organization.

It works quietly without making any noise and comes with a separate compartment for tips storage. The volume of the water reservoir is 800 ml which is higher than most water flossers
- Women Dentists
What experts didn't like
The unimpressed testers complained about leakage, noise, and that it quit pumping water after a while.
- Gadgets
Larger design is space-consuming
- Wise Pick
However, the larger reservoir does have its drawbacks: it makes for an overall bulkier device which, paired with a slightly dated design, means the hf-8 does not look quite as sleek as rival models.
- The Toothsayer
Large tank design takes up space on your bathroom counter
There are 6 pressure settings to adjust and it is enabled with a 120V/60Hz outlet, which means that it can only be used in North America.

Messy – Whilst you can master a technique, the steps involved and the amount of water pushed into the mouth means this is not the most enjoyable or flattering experience, you need a sink and even then you can make a bit of a mess.
- Electric Teeth
June 20, 2018 | Full review
Water splashes everywhere and it is difficult to control the speed at which the water flows.
- Best Advisor
The switch on the handle is hard to operate. Many users report having trouble operating the power switch on the handle of this water flosser, stating that they have to use two hands to do so.
- Review Lab
The jet tips begin to leak after a few months of usage

An Overview On Water Flossers

Water flossers have many different names, including oral irrigators, dental water toothpicks and and Waterpiks, which is actually the brand name for one of the more well-known water flossers. No matter what you call them, these handy devices work well in conjunction with daily tooth brushing to clean between teeth and around the gums.

When shopping for water flossers, there are a few things you’ll want to consider before making a purchase. Start off examining the oral irrigator’s pressure settings. There may be a time when you need soft, medium or hard pressure. With 10 pressure settings that begin at 10 PSI and end at 100 PSI, the Waterpik Aquarius Water Flosser is sure to give you the clean you’re looking for.

Next, check the number of tips and their designed function to make sure they meet your needs. The H2oFloss Professional Countertop Water Flosser has 12 multifunctional tips that can be used by everyone in the family. There are four jet tips, two tongue cleaning tips, two orthodontic tips, two periodontal tips and two nasal tips.

Determine whether you need your flosser to be stationary or portable. If you do a lot of traveling, for example, you’ll want to choose a model like the Nicefeel Cordless Water Flosser Teeth Cleaner, as the cordless feature, smaller design and the accompanying storage bag make it easy to grab and go.

Review the capacity of the water reservoir to determine how often you need to refill it. The MOSPRO IPX7 Professional Cordless Water Flosser has an extra-large reservoir when it comes to portable units with a tank that can hold 300 ml. Stationary units will hold more.

Look for any extra bells and whistles that might make the oral irrigator easier to use. Some models have built-in timers, so you know exactly how long you’ve spent flossing. Others have a memory function that keeps the device on the last pressure setting you used.

DYWM Fun Fact

Water flossers are an excellent alternative to traditional string floss, as many studies have revealed that they actually have significant positive results when it comes to your oral health. Not only are water flossers 51% more effective at reducing gingivitis than string floss, but they are also twice as powerful at reducing gingival bleeding. They do a better job at removing plaque as well.

You may be wondering how water flossers came about. It was actually a dentist in Colorado, along with his patient who happened to work as a hydraulic engineer at the time, who created the first water flosser. The water flosser was then marketed to other dental practices in 1962. Today, we can find them in department stores, pharmacies and online stores, like Amazon.

The Water Flosser Buying Guide

  • Always check the water flosser’s product label for the American Dental Association seal of approval. This seal lets you know the product has been thoroughly tested and meets the strict requirements set forth by the organization.
  • Look to see if the oral irrigator has a product warranty and how long that warranty is good for. Warranties vary greatly among flossers and can be anywhere from 12 months to 3 years. You don’t want to risk the product breaking down after just 3 months of use and having no way to recoup your money.
  • Determine if the outlets are compatible with your area of residence. Some flossers are only compatible with 110VAC/60Hz outlets, which are what you’ll find throughout North America, while others use USB ports for charging.
  • Keeping your water flosser clean is important. Read the product label to see if any of the flosser’s parts are dishwasher safe. Some may require you to run 2 tablespoons of white vinegar mixed with 16 ounces of water through the system. Afterward, run warm water through the system to rinse out the vinegar. You can also soak the flosser’s handle for 5 to 7 minutes in a cup that is filled with 1/3 white vinegar and 2/3 water. You should do this once a month.
  • When comparing prices for water flossers, you need to take into consideration the type of oral irrigator. For example, the Nicefeel Cordless Water Flosser Teeth Cleaner and the MOSPRO IPX7 Professional Cordless Water Flosser are designed for travel, so their cost is going to be different than the Waterpik Aquarius Water Flosser and the H2oFloss Professional Countertop Water Flosser, which are made to rest on your bathroom sink. You’ll also want to consider how many tips you get and how many pressure settings the unit comes with. More features equal a higher price.
