The Express RO5DX presents a simple way to filter your tap water at home. It’s a straightforward RO system with a decent filtration performance at an affordable price which makes it an ideal option for those working with a very small budget.
Like most other systems, the RO5DX utilizes a 5-stage filtration process to deliver safe and clean drinking water. The filters from stage one to four remove all possible contaminants in the water source.
The 5th stage consists of a post-activated carbon filter that takes care of odors and residual taste. However, there’s no remineralization filter, so you will have to buy it separately.
The unit can produce around 50 gallons of pure water a day which is standard for most RO units. Combined with the 4-gallon storage tank, you will have sufficient clean drinking water every time.
The best part is that this Express model features an emergency leak stop detector. When the tank is filled, it automatically shuts off the system to stop the water flow into the unit. Hence, there no danger of water overflowing from the storage tank.
For every gallon of pure water produced, three gallons are wasted, so it’s fairly efficient and will save you some money in the long run.
The unit comes with complete push-in quick-connect fittings that are color-coded to let you know what hose goes where. Plus, the instruction booklet is detailed with diagrams and colored illustrations to aid you.
Therefore, it’s quite easy to install and to replace the filters too if you have basic plumbing skills. However, the filters are not long-lasting like in the other units above. The pre-filters need replacement twice a year while the RO membrane and the post-carbon filter need to be replaced once a year.
In general, aside from replacing the filters frequently and the fact that it does not feature a remineralization filter, everything else is perfect and well built.
If you have a tight budget but still want a unit that’s capable of delivering clean drinking water without any issues, then the Express RO5DX might be a good option for you.
