ProFloss 4190 Water Flosser – Is It Any Good?

The ProFloss 4190 is one of the most unique and affordable water flossers available.

Whilst most other water flossers use some kind of electrical source, the ProFloss 4190 attaches to a faucet. This means that all you need to do is plug it into your tap and floss. This innovative design is ideal if you don’t have a power socket in your room or aren’t too keen on the idea of having a battery powered flosser. Attaching to a faucet also means that there’s no reservoir that needs constant filling up – the water just flows straight from the tap.

 Whilst ProFloss may not be as well recognized as other brands, it was founded in 2009 with the purpose of creating a water flosser which could be packed away when it wasn’t being used. Additionally, creator John Mueller aimed to address other downfalls of common water flossers, such as the hassle of filling up a reservoir and the high price tag attached.

But does the ProFloss 4190 deliver on its promises? We’ll find out in this review.

The Basics

Firstly, it’s important to understand that water flossers come in many different shapes and sizes. Cordless flossers (usually battery powered) and countertop flossers (which plug into a power source) are the most common types. They will often have a “reservoir” – a space built in to the flosser that you need to fill with water before (and sometimes during) use.

No reservoir May be difficult to attach to the faucet
4 pressure settings Cord length
No electrical power source

Easy to pack away

Aside from price, there is one main difference between the ProFloss 4190 and your average water flosser. Rather than needing a power source, the ProFloss attaches onto your faucet, making it safer to use and easier to pack away. The ProFloss 4190 has 4 different pressure settings, which is more than your average cordless model (which has around 3) but less than your standard countertop model (which has up to 10 settings). The average person uses no more than 3 settings, which the ProFloss 4190 happily provides.

Generally, the less positive aspects of the ProFloss 4190 seem trivial. As long as the aerator fits on your faucet (it will fit most faucets with 15/16” outside faucet threads or 55/64” inside faucet threads), for the price and effectiveness, the lack of an on/off button or the 42” cord length seems insignificant.

How to install the ProFloss 4190

  1.       Remove the existing faucet aerator. The aerator is the bit right at the tip of your tap. It unscrews in a clockwise direction. It’s worth making sure both your hands and the end of the tap (including the aerator) are dry before removing it. If it’s tough to remove, you can try using adjustable pliers.
  2.       Install the ProFloss aerator. The design of the ProFloss 4190 means that once you’ve switched to the ProFloss aerator, you don’t have to worry about changing it again. The ProFloss 4190 attaches to this aerator, but if you’re not using your flosser, the tap will function as normal.
  3.       Insert the ProFloss pick into the handle and select a water flow option. There are four different settings to choose from.
  4.       Reattach the house to the aerator, then turn on the water and floss!
  5.       Detach the hose from the aerator after use. Once you’ve done this, the flosser can be stored in the zipper pouch provided.

Key Features

Water powered

Not requiring a power source is the feature that sets the ProFloss 4190 apart from other water flossers. Many devices need to be plugged into a socket which is frustrating if you don’t have one in your bathroom. Avoiding the safety hazard of mixing water with electricity also means that even the smallest child can benefit from it. Furthermore, it’s ready for use at any time – once you have attached it to the faucet, it’s as simple as turning on the tap!

Cordless oral irrigators run off batteries or need charging up beforehand – not the case with the ProFloss 4190. You never have to worry about changing batteries or forgetting to charge up your flosser. Also, countertop flossers need to be close to a plug socket, whereas once you’ve attached it to the tap, your ProFloss 4190 with be in prime position near the sink. 

Unlike other water flossers, there is no need for a reservoir because it is powered directly by water from the tap.  This means that you don’t have to fill the reservoir up before using it, or stop mid-floss to refill it. It also makes it easier to keep clean and hygienic, as the constant flow of water makes it easy to rinse out. This also helps to avoid a build up of stale water and prevent bacteria growth.

Size and portability

The lack of reservoir and power source makes the ProFloss 4190 compact and easily portable. It measures 8” in height, which is only marginally taller than your standard toothbrush. It’s lighter than the latest iPhone X and comes with a pouch to store it in. This means that it can be stored in a drawer rather than taking up precious space on the countertop. Since it’s compatible with most faucets, it’s also useful for travelling.


ProFloss was founded with affordability in mind. Water flossing has many benefits yet many water flossers cost $70+. With cordless oral irrigators ranging from around $30-$50, and basic countertop models starting at $60, the ProFloss 4190’s price is unbeatable.

What’s the verdict?

The ProFloss 4190 is ideal if you want a water flosser that is effective without breaking the bank. Its unique design is powered solely by your tap, meaning that it doesn’t have to use an electrical power source. It also doesn’t take up any counter space as there is no reservoir or pump. If you want affordability without compromising on quality, the ProFloss 4190 is a very commendable route to take!
