A recent study by the Environmental Working Group (EWG) on the quality of tap water in the USA revealed the following:
- 81% of all American water contains cancer-causing contaminants
- 77% of Americans drinking water that contains hexavalent chromium
- Water samples taken from all 50 states contain arsenic, disinfection byproducts, nitrates, radiological contaminants, arsenic, and other dangerous substances.
The EWG recommends that people should install reverse osmosis (RO) filters. As they are the most effective way of filtering water and removing the for most common, as well as dangerous contaminants such as:
- Nitrites
- Cadmium
- Arsenic
- Chlorine
- Barium
- Lead
- Fluoride
- Nitrates
- Phosphate
- Radium
- Chromium
- Selenium
- Bacteria
- Cysts
- Viruses
Where do you start? Choosing your first reverse osmosis (RO) water filter systems can be tricky and, in many cases, overwhelming job. We trust our partners to provide us with a reliable source of tests and reviews. Each contains detailed and dependable information about the best water RO filtration systems on the market.

We have composed this article to assist individuals with discovering the best RO filtration system to suit their necessities. We additionally talked about some well known and useful extras that you can add to a current RO system. After perusing this article and you choose that an RO system isn’t the correct alternative for you. If it’s not too much trouble don’t hesitate to look at our different surveys of house water filtration systems.We wrote this article
We have chosen what we believe are the top 10 point-of-use under sink water filter systems that can be installed and used at a single location. These systems will also include separate faucets that should be installed next to your standard faucet. These should only be used as a source of filtered water just for cooking and drinking.
The systems are not difficult to upgrade and an extra water line that can extend to the refrigerator, to make sure that your ice maker and water dispenser also use filtered water:
1. Home Master TMAFC-ERP Artesian Reverse Osmosis (HMAROS) System
The TMAFC-ERP Artesian RO system from HomeMaster is our top pick because it is a perfect combination of features, benefits, and value. It has two significant features that set it apart from all the other mid-range options we tested, making it the best RO system on the market.
Too many RO systems produce purified water that has what can only be described as a bland taste. In some cases, it could even be slightly acidic. As the RO process has removed all the minerals that previously gave the water its taste and flavor. But this is not the case when your water is purified using the TMAFC-ERP RO system.

Once the system passes water through its purification membrane, it starts a remineralization process, which will add back in safe minerals and raises the pH to make the water more alkaline. The result is a fresher tasting mineral-like water that consumers prefer. The system has been modeled using a pervade pump; these are non-electric devices that are used to enlarge water pressure before the water enters the filter.
There is no doubt that these systems are created to decrease water waste by up to 80% and increase the production of water by 50%. These factors are crucial for people who live in cities and have to pay for water rates, as most standard water filtration systems are known to waste up to 3 gallons just to produce one purified gallon.
After testing, the TMAFC-ERP system revealed that it only wastes the gallon of water to create one gallon of purified water. This RO system operates using a seven stage filtration process and is capable of producing around 75 gallons of purified water every single day.
The HomeMaster it’s also designed to use top-quality filters, which are modular in design, making them easy to change without the use of any tools. This RO system is also very straightforward to install, and anyone with some necessary DIY skills should be able to complete the installation in around an hour.
Each unit also comes with its own pressurized storage tank and faucet. HomeMaster also offers a 5-year part and warranty guarantee, which is more than any other manufacturer on our list. HomeMaster also provides you with an impressive list of accessories that allow you to get more out of your RO system.

If you aren’t too bothered about all the fancy accessories that will come with RO systems and you don’t have time to compare every single option, Then the HomeMaster HydroPerfection RO system is the one for you. It comes complete with a 9 stage filtration system and every prime feature of any RO system on the market.
This is the system that we endorse for people who already have a natural water source such as a well. The Home Master TMHP has a booster pump, which increases its output to 75 gallons per day and further reduces any wastewater that can be lost while the water is flushing through the membrane. Only one gallon of water is wasted to produce each gallon of purified water.
Featuring a remineralization filter that puts back safe minerals to the water as well as raising the pH to increase its alkaline level,l this RO filter creates purified water that tastes like mineral water. An additional feature is the UV light that has been installed to kill 99.8% of the microorganisms that can contaminate drinking water.
We recommend this filter for people who use their own freshwater sources as this traditionally has much higher levels of microorganisms when compared to municipal water sources. If you do reside in a more remote area, you need to recall that the system requires a 105V power source.We suggest this filter for people who use their own freshwater sources as these typically have higher concentrations of microorganisms
This system is also designed to produce up to 75 gallons of purified water daily. The system is a modular filter systematically structured to be easy to change. It’s also quite uncomplicated to install, this can be achieved in under an hour for anyone who has the most basic of DIY skills. Every system comes with a pressurized water tank and faucet. HomeMaster also offers 5-year parts and warranty guarantees.
3. Waterdrop RO Reverse Osmosis System
This powerful new RO system is designed to fit under the sink and has some excellent features, as well as a sleek, compact design.

Click photo for a direct link to your product.
Tankless design
This system is unique compared to most RO systems on the market because it doesn’t require a pressurized storage tank. The water filters through the RO system as needed without needing to store water in advance. This means the system will have no lag and produces less wasted water.
High Output
The dearth of a storage tank and its use of an internal pump allows this RO system to produce up to 400 gallons per day of filtered water. This, compared to the average of 70 GDP from competing systems, is an incredible return on investment.
Neat LED to indicate filter status.
We really like the setting up of the LED ring on the faucet, which is designed to use different colors to show you the status of your filters. Besides, it has an LCD panel that displays the current TDS as well as your filter status. The vast majority of RO systems in the market requires you to install a third-party
TDS meter to be provided with the same water quality information.
This is truly an excellent product when you can factor into account, it produces more purified water while taking up less space and offers much better feedback than any other system.
