What is a UV Water Purifier, and How does it Work?

Benefits of using a UV water purifier

What to Consider when buying a UV water purifier?
Before you buy a UV water purifier, make sure to check all the features that you need in your UV water purifier. You have to identify your needs first, whatever features or characteristics are more important for you. After that, choose one that meets your criteria.
Cost
Identify first what is your budget for a UV purifier and check what options are available in that range. Some purifiers cost more than others but still may not give you the result that you want.
Your needs
The biggest question is whether you need a UV purifier. Some of the filtration systems already have a UV light in them. Now, if you do not already have any filter systems installed in your house and you will get a UV purifier for getting purified water, but that will not be efficient because the UV light only removes microorganisms from your water. So, it does not remove any heavy metals and chemicals from the water.
Water flow rate
There are UV filtration systems available that already have a booster pump in them. The booster pump significantly improves the water flow and makes the process of cleaning more efficient.
Space
There are different UV purifiers available in different sizes, and you have to see what type and size of purifiers fit perfectly in your house and choose according to the available space.
Quality
Based on your budget and the cost of the actual UV light purifier, there is one thing that you have to keep in mind, and that is the quality of the purifier and its performance. Before making your purchase, make sure that you are buying the most excellent quality UV purifier available on your budget.
Bulb lifespan
The different brands have different lifespans for their UV lamp, the standard lifespan of these lamps is 6-12 months. Check the lifespan of the lamp before getting a UV purifier for your house.
Installation and Maintenance
Installation of the UV water filter is very easy and quick.
First, Decide the place where you want your filter installed. The UV filter is most likely to be with other filters. You will have to choose a place where the system will fit perfectly. If you already have a system installed in your home, you can add an additional UV purifier to it. Now, if you are getting a whole system with a UV filter in it, always install your UV filter in the end.
You have to install the mounting ring where you want to set up your UV purifier. Before you set up the mounting ring, make sure you are following the instructions about whether to install the UV filters vertically or horizontally.
In the next step, you have to mount your UV lamp housing on the mounting ring you installed. Make sure that it is perfectly fitted in the wall or wherever you have installed it in a way that it won’t fall off.
If the housing is fitted perfectly, Insert the inner housing or the UV lamp into the outer housing that you mounted on the wall. You might receive O-rings that help the lamp to stay accurately fitted in the housing. There will be another rubber in-lock that is supposed to make sure if the O-rings fail, the lamp remains intact in the housing and doesn’t fall off.
Connect the water lines after making sure that your UV purifier is perfectly set up. Do not turn on your water line just yet. Connect your lamp to electricity after you have fitted the lines.
Turn on the waterline and get water that is free from all bacteria, viruses, and pesticides.
Maintenance of the UV water purifier is frustration-free. You might need to clean the inner housing every few weeks to ensure that the UV lamp’s light does its work. When you purchase the filter, there will be advice on the duration of the UV lamp when it needs to be changed. If you clean it up and change the lamp when needed, your filter will give you the most efficiency.
If there is another water filter system before the water goes through the UV filter, you have to make sure that the filter cartridges of that system are changed in a timely period. There is a duration meter that monitors the hours the UV lamp stayed on. Usually, the duration for a UV lamp is 9000 hours. The meter shows the hours used and the hours remaining before the need of changing the filter. That way, it is easier for you to keep track of when to change the lamp.
