The Ultra Violet disinfection systems are specifically designed for both residential and commercial buildings requiring the removal of bacteria. This process is accomplished without adding any harmful chemicals to your drinking water. The Ultra Violet disinfection systems are the most ecological way of treating your water for bacteria… and all this for just pennies a day!
Yes, a 20 micron pre-filter is recommended to prevent the bacteria shielding behind particles in the water.
It has been known for over a century (Schenk 1891) that the ultra violet wavelengths present in sunlight have germicidal effects. The practical utility of UV radiation for the control of organisms followed the devising of the mercury vapour lamp. This form of radiant energy induces photochemical reactions involving biomolecules in micro-organisms. The resulting molecular alterations inhibit the growth of micro-organisms, and in higher concentration will kill them. The method of generating UV radiation is by discharge lamps. The quartz tube contains an inert gas plus a metal, mercury. Electrodes located at each end of the tube, may be cold or preheated.
Lamps are based on mercury / argon mixtures these exhibit the highest efficiencies and are the best performing bulbs. During discharge, particularly at low pressures, mercury atoms in their excited states radiate mainly at wavelengths of 184.9nm and 253.7nm resulting in the generation of UV light. UV-C is used primarily to destroy organisms. The 253.7nm light emitted by low pressure mercury discharge lamps can inactivate micro-organisms such as Protozoa, Bacteria, moulds, yeasts, viruses, fungi and algae. It is this type of lamp that is used primarily in the UV disinfections of water.
UV disinfection system destroys bacteria to a factor of 99.999%.

Ordered the salt but it was not delivered to me and just returned to seller without notifying me.
So disappointed with the purchase. Can the sales contact me to arrange return and refund for the softener and salt???read more
also ordered salt delivered really quick and good price.read more

Update: (12-11-2022) on weds i rang again and this time was finally given an install day of coming saturday. The installer called me to confirm saturday 0830-0900. Come saturday no show from the installer guy and not responding to my messages. Again awful service.read more

I’ve used there chat box system which always says someone will get back to me in 24 hours and they... never do.
I’ve emailed numerous times with no response and can’t get through to anyone on the phone lines.

Dog var der lidt problemer med deres mail service så jeg først fik besked om af pakken var sendt efter jeg modtog den.

L’acqua prodotta è molto buona. Il montaggio è estremamente semplice e la scatola incluse tutto.
Il costo dei filtri in sostituzione è contenuto.
Gli impianti sono... tutti funzionanti correttamente.
Ovviamente ogni acquisto fatto era più aggiornato dei precedenti ad indicare che lavorano per migliorareread more
L’installazione è stata abbastanza semplice, come la configurazione grazie all’app dedicata. Addio calcare… lo consiglio certamente.
The systems are brilliant, the water comes out clear and taste free, and is easier to drink than any other water I have tried. With a cheap electronic tester, I found that the RO water had less particulates than mountain spring water (from Facha, Viana do Castelo) and less than distilled water from the supermarket. Consequently I also use it in my solar power battery bank without hesitation.
I needed some spare parts recently, they were sent FOC and with free delivery from Ireland (not UK after Brexit). The customer service has been faultless (thanks Steve).read more
