FIVO offers a filtration system RO Premium for domestic use in geographical regions with medium hard to hard water (please refer to the map showing different type of water in different regions in Bulgaria).In these regions the hardness of water varies from 11 to 28°dH (German system) or 200 to 500 PPM, measured by a TDS meter. This is a 2-STEP FILTRATION DEVICE with two last generation combination filters. The first one is a membrane REVERSE OSMOSIS filter (which needs to be replaced every 36 months) and the second one is a PCB Composite (which needs to be replaced every 12 months).

REVERSE OSMOSIS is a membrane filter with especially fine pores which filter particles up to 0,0001 microns in size. The specific thing about the membrane is that in order to remove >99% of harmful substances dissolved in water, the flow of water needs to pass through the membrane at a high pressure. This requires the use of a pump as part of the system, as well as electric supply for the pump.

PCB composite filter is a combination of 3 filters with different contact surface and composition. Its purpose is effective filtration of slime, rust, dissolved substances, chlorine; absorption of odours, colouring, and some organic substances (chloroform, tetrachloride) in the water.

Installation of the device is performed by FIVO’s specialized engineers. The system could be installed under the sink or on top of the kitchen counter. The easiest possible way is to connect the device to the soft link for the cold water, to which an electric branch (triple) and a faucet are added. The water then is led to the entrance of the filtration system, then to the storage container, and finally it goes to the mixer

ATTENTION! With REVERSE OSMOSIS membrane filtration, the membrane disposes of “dirty” water in the drain. The membrane has an exit section which needs to be connected to the drain under the sink through an additional hose.


After the water is filtered through the system, it is led to the end consumer. There are 3 different ways for this happen, according to your conditions and wishes.

  • The first one is through installation of an additional mixer which is part of the UF system. It is installed at a convenient for the client place near the sink. It is important to note that for this you will need a second hole next to the first mixer. The client may prepare the opening in advance, or it could be done by our technician. For the most common sinks (aluminium or alpaca), the drilling would be easy and hassle-free, and there would be no risk of damaging the sink. In case the sink is made from another type of artificial alloy, technical stone or natural material, the drilling is more complicated and there is a risk of damaging the sink. In these cases, the client accepts the risk and the FIVO team does not claim any responsibility.
  • Another option for the client is to buy combined base mixer which would replace the current kitchen mixer with a new one. It is sold freely in the commercial network, and it is combined because it has two control modules – one is for the water from the water supply network (warm and cold), the other one (smaller of the two) is connected to the water filtration system. In this case, the client decides when they want to use filtered water and when to use regular water.
  • For the third option, it is possible to directly connect the filtered water to the old mixer, without an installation of a second one, or replacement of the old one. A negative result of this option is the lower running water pressure which would present a certain inconvenience if you use the water for washing household utensils, hands etc. This also results in shorter lives of the filters, which would lead to a more frequent replacement.

The filter expense per year is approximately 123 BGN (VAT included).*

As per the client’s wishes, the FIVO team can send a reminder about filter replacements.

*The figures are approximate.

The duration of effective work of each filter depends on the consumption, the type and purity of water in the region, as well as on the condition of the water supply network infrastructure in the region.
