Ordinary single RO water purifiers have a low utilization rate and are easy to crystallize at the end. VIOMI’s original dual RO technology splits the original single RO into two main and secondary RO filters. The crystalline tail and secondary RO parts can be replaced separately. This saves users money, reduces resource waste, and is more environmentally friendly; small filter elements is replaced every year , the main filter element has a service life of up to 5 years, which greatly extends the service life of the RO filter element.
