Express Water is a Taiwanese company that focuses on easy to use and install one-stop systems that can handle all your drinking water needs.
The Express Water ROALKUV10M RO system is an 11-stage water filtration system that claims to remove 99% of water contaminants. It can produce 0.8 gallons per minute and 100 gallons of purified water per day.
The system’s 1st stage is a sediment filter that removes dust, sand and dust. The 2nd and 3rd stages use carbon block and granular carbon filters that remove volatile organic chemicals, chlorine and odor-causing compounds.
These early stages are extremely important as they help extend the life of the RO membrane(4th stage). This filter helps purify your well water as it focuses on the most stubborn impurities like lead, arsenic, TDS, fluoride and others.
The 5th-9th stages use the alkaline filter, which adds antioxidants, 5 stages of mineralization and oxygen to the water. The 10th stage is UV filtration, which removes microorganisms like E.coli and bacteria. In contrast, the 11th stage (final stage) is a post activated carbon filter that removes any lingering taste or odor from your water.
All filters used in the system are double sealed to provide filtration efficiency and value. They are easy to replace, with the pre-filters being swamped only twice a year. The RO membrane, post carbon and the alkaline remineralization filters require replacement once a year.
In case of a leak, the system’s leak detector shuts off the water flow automatically.

Things to Consider Before Getting an RO System for Well Water
- Water Output
Water output is simply the amount of water a system can filter in a day. The higher the water output, the better. And one thing you need to be extra keen about is that although some brands advertise their products to have an output of 100 or more, this might not be the case.
Some of these figures are only achieved with ideal water temperature and water flow conditions. Don’t be surprised to find out that, in reality, the output range of the products is much lower than the indicated figure.
So, how do you overcome this?
Research about the brand before ordering for the RO system. You can also check some online customer reviews for assurance.
When removing contaminants from well water, essential minerals like calcium and magnesium are removed as well. Remember, you need these minerals as they are important for your health.
Go for an RO system that offers remineralization to restore the minerals to your water and improve its taste.
- Waste Water
Although RO systems are highly effective at removing contaminants from well water, they produce a lot of waste for every gallon of purified water. Some even waste 4 gallons of water to produce just one gallon of pure water!
But do you know that there are systems that produce less waste water? Those that have a drain ratio of 1:1? You only need to do a little market research to end up with a system that helps you save more water for cooking and drinking purposes.
- Storage tank
The capacity of your storage water tank dictates the amount of pure water you can have ready for use at any given time. The larger the tank, the higher the capacity and vice versa.
Without a storage tank, you can only draw water as the system filters it, meaning that you’ll experience a limited water flow rate.
High-quality reverse osmosis systems help improve well water quality by removing the contaminants that make it unsafe for drinking. We’ve included the above list to help you take no chances but end up with an RO system that fits your needs.
The included buying guide should also help you overcome some of the issues that can lead to a wrong product choice. With the best RO system for well water, you are assured of clean, pure and great tasting water at all times.
