ClearLight™ Ultra Violet System – Up to 79L per min
The ‘perfect solution’ for people with private water supplies
This is one of the larger size Ultra Violet system we stock.
It’s designed for a flow rate of up to 79 litres per minute.
This is a high rate and would usually be for a larger property / house or a light industrial property on a private / non-mains water supply.
Is This the Right Size for You?
UltraViolet filters should be sized according to the flow rate of water going through them.
Flow rate is different to water pressure ie “Bar”. (This is because, for example, 3 Bar of pressure will result in a different flow rate on a 15 mm vs a 22mm diameter pipe).
You can read more about your flow rate, and how to measure it here
Check the UV Filter Size Chart
There’s no point in getting a UV filter that’s either too large or too small. Checkout this chart where you can click through to your right size filter.
It includes the variations between being “off grid” vs on normal mains electricity

Off Grid?
This unit requires mains electricty.
We do supply 12V ‘off-grid” UVs, but only up to 22L/minute.
If you need a larger off-grid electricity UV then a solution is to buy smaller 12V UVs and split your incoming water so that it flows equally through the smaller UVs (Note the water needs to be split on a “manifold” basis – ie so it passes equally between the smaller UV units – not made to flow “in series”.)
A plumber should be able to arrange this easily.
You can see a chart of the smaller 12V off grid UV units here.
We might be able to offer you a discount for buying more than one unit. Contact us to discuss your needs.
Pre Filters
UV systems are long thin tubes with what looks like a fluorescent bulb sitting in the middle. (This is the UV lamp).
The incoming water flows down the tube, around the UV light/lamp.
Any micro-organism (ie bacteria and viruses) that are hit by the light will be rendered harmless.
However any sediment / particles might create a “shadow effect” / “umbrella effect” and help the micro-organism to escape bieng exposed to the UV light.
The pre-filter removes these sediment / particles.
Running Costs
The UV lamp/bulb needs changing every 12 months. This is regardless of usage. (For example; if you go away for a few months, to ensure total safety you would still need to change the lamp/bulb 12 months after installation.
Cost of replacement lamp for this unit £167. (Check the product page for current quantity / discount deals).
The pre filters change rate will vary*. It depends on how much sediment / dirt they trap. This varies with the quality of your local incoming water – which can change after storms etc.
Assume the pre filter cartridges will last at least three months.
Cost of replacement pre-filter cartridge for this unit £25 (Check the product page for current quantity / discount deals).
