Water Filters – Frequently Asked Questions?

Since 2001 Celtic Water Solutions has installed an maintained water treatment systems and filters for a wide range of customers. We have written this frequently asked questions blog post to aide you with your water filter questions. While this may be of benefit and answer some of the most common questions posed to us over the years, if you do not find an answer here we would encourage you to contact us  with your questions so as we can provide you with a fully comprehensive answer.

How often should I replace my water filter?

One of the most common questions we hear in the office of Celtic Water Solutions is in relation to how often a water filter cartridges should be changed, whether it be a standard sediment or carbon filter, or reverse osmosis membrane, every customer has two key priorities in mind, How long will I have dependably clean, great tasting water, and how can I be certain that my filter is still removing the impurities that can impact on the flavour of my water and the health of my family? To ensure the filter continues to reduce contaminants, we recommend it be replaced every twelve months.

If you do not change the filter, while it may look clean it will become clogged, causing the water flow and the water pressure to drop, this in turn will make pumps work harder to try and boost the water pressure and flow which can then cause damage to the pumps and equipment. Also as a result of less flow and pressure the filter will no longer continue to filter the water correctly.

What is a Micron Rating?

The average size of the openings between pieces of the filter media are represented in microns. For example, a 20 micron filter has larger openings than a 5-micron filter, as a result the 20-micron filter will allow larger particles to pass through the filter than the 5-micron media would. A general rule of thumb is the smaller the micron rating, the better.

How can I filter bad smells or taste from my water?

As long as the actual cause is filtered before, as an example iron the water, which is removed with an iron filter can sometimes leave a bad taste or unpleasant smell. This can be removed using a carbon filter which is the same size as a sediment filter but instead of catching sediment it will treat the water and the carbon reacts with the foul odours and tastes.

How can I remove chemicals from the water?

Chemicals can come in all shapes and sizes, salts to nitrates. They can be removed using numerous types of filters but the most common is a reverse osmosis filter.

Why Must I Change My UV Bulb When it is Still Lit?

A UV lamp is not an ordinary light bulb. One of the most misunderstood things about a UV water treatment system is why the lamp should be changed even though it still appears to be working. Why is it that the useful life is typically defined as 9,000 hours, or about one year of continual use? 

The problem arises from the fact that for most of us, our understanding is heavily influenced by our experience with incandescent lights. These are your garden variety bulbs, used in most household light fixtures, it is not necessary to change or replace this bulb until it quite literally burns out. 

An incandescent light bulb works by passing electricity through a tungsten filament. This generates heat that causes the tungsten to glow. That glow is the visible light spectrum, so we see the light. The tungsten filament is deteriorated with use and eventually it becomes so thin that it quite literally snaps, and no longer lights.

A UV lamp, however, operates on a different principle, more like a fluorescent light. In this case, the electricity is still passed through a tungsten filament which heats up, but that energy “excites” the mercury vapor contained in the lamp. (Not to worry, only a very small amount of mercury is used, typically <10 mg, and it’s safely contained.) In this case, it is the mercury vapor that glows and, emits ultraviolet (UV) light. This is exactly what’s needed to inactivate any pathogens in your water supply.

As you may know, UV light is not visible to the naked eye and is, in fact, quite damaging, so never look directly at a UV lamp while it’s on. If your system has a view port, you may see a blue glow from the lamp, but that’s not a result of the UV rays. Remember, UV light cannot be seen by the human eye. This glow is simply a by-product of the lamp’s operation. The useful life of the UV lamp is determined by the rate at which the mercury is consumed. That very small amount of mercury contained in the lamp will provide sufficient UV rays to disinfect the water for about one year. After that, although the lamp appears to be working, there is not enough UV produced to safely drink the water.

Changing the lamp on time is critical to ensuring your safety. That’s why many UV systems have a timer that will count down from 365 days and then sound an alarm to let you know it’s time for a lamp change.
