Which Water Purifier is Best for Your Home? RO, UV, MF, UF, Alkaline, PH. What the hell do you prefer to buy? What are your taste and preferences? Are you really sure you have to search for the right water purifier? If you have seen the many, many pages of the many, there are many best water purifiers that are available, there are so many different technologies to choose from.
But what is the right technology that is right for you, and for your house? For the water conditions in your house? Let’s take a look at it here. In today’s tutorial, I will help you decide which technology is right for you, and then, based on that, you can jump to the tutorial if you need an RO water purifier, or a UV, UF, and so on.
But I have already done my research, so I have provided the best water purifiers in each of these categories. Let’s take a minute to try to understand these various technologies. I’m not going to go into too much scientific detail because everybody gets bored of it. I do as well. But you need to know the basics just to make the right choice of water purifier for your home.
Which Water Purifier is Best for Your Home?
Well, now we had come to the point. You might have a doubt or you may be confused on thinking upon Which Water Purifier is Best for Your Home? To clear your confusion or to give you the basic idea, make sure you go through the following or useful information shared just below.
RO Technology OR Reverse Osmosis Technology
First is the RO technology or reverse osmosis technology. Now, this technology is used to remove hardness in water. It is also used to remove bacteria, viruses, and other contaminants in your water. But the biggest problem with the RO is that it does remove the essential minerals from the water as well, which essentially then makes the water useless.
It also makes the water acidic, which can be detrimental to health. There are technologies that you need to add to the RO water purifier to make sure that the water is consumable. And RO water purifiers remove the maximum amount of contaminants from water, up to 0.0001 microns. And that’s the best in this category.
UV or Ultraviolet
Next is UV or ultraviolet, which kills bacteria and viruses from the water. But it does not remove it from the water. Next is ultrafiltration or UF. This removes suspended particles from the water but does not kill bacteria and viruses. If you are using it in conjunction with UV, so UV will kill the bacteria and virus. And UF will then remove that bacteria and virus that still is floating around in the water.
MF or Microfiltration
The next technology is MF or microfiltration. Now, this is one step lower than ultrafiltration. And this removes particles only up to 0.1 microns. And it only filters bacteria but does not filter out viruses.
Alkaline Balance or PH
Next, you will hear something like alkaline balance or PH level balance in the water purifiers. What is this? Alkaline filters, or PH balance, are used to, like the name suggests, balance the PH levels in water from being too acidic or too alkaline. Typically, when you do use an RO water purifier, it makes the water a lot more acidic. And for that reason, whenever you’re using an RO water purifier, you need to make sure that there is alkaline or a PH balance available with that water purifier.
Now, that we have discussed the basics of the various technologies, let’s jump right into what is the right water purifier for you. Hence without making any delay leys head over to it.
What is the Right Water Purifier for You?
First, what do you purchase if you have hard water in your area? Typically, if you’re getting water from borewells or tankers or it’s mixed water, your TDS levels will be higher than 200ppm.
What is TDS?
TDS actually determines what are the total number of dissolved salts in your water. It could include various salts, calcium, magnesium, and other minerals in the water. Too much of a concentration of that is not good. And that’s why you need to bring down your TDS levels to less than 200ppm.
WHO recommends that drinking water should have a TDS level of less than 200ppm. How do you measure the TDS? You get a lot of TDS meters in the market for Rs200–Rs250.
If you have a TDS of less than 200ppm, a UV or a UF or a combination of UV-UF filters is sufficient for you. If you have a TDS of 200–500 ppm, depending on whose standards you want to go with, you may need an RO or a UV and UF filter.
According to the Bureau of Indian Standards, or BIS, states that up to 500ppm is okay for drinking water. But WHO says that less than 200ppm is better for drinking water. So, if you go by WHO standards, you will need an RO water purifier. If your TDS is between 200 and 500. If your TDS is above 500ppm, then definitely you need an RO water purifier.
Do you need a UV plus UF combination or just a UV or just a UF?
So, you get water purifiers in each of these categories. So, as I mentioned earlier, UV kills bacteria and viruses. And UF only filters out bacteria and viruses. So, normally, you would need a combination of both UV and UF unless you’re using a gravity filter, which only then comes in a UF filter.
So, my recommendation is, whenever possible, to try to use a UV plus a UF filter. So, do you need an RO plus UV plus UF filter? RO also kills bacteria and viruses, so RO plus UV may be a redundant combination. But if you want to filter out those bacteria and viruses, you definitely would require a UF.
I think what’s more important is that you need to make sure that your RO filter also has an alkaline or a PH balance available with it.
Are there any ongoing costs? Definitely, yes. Especially when it comes to an RO water purifier, the ongoing costs are significantly higher. You need to change the filters in an RO water purifier every 6–7 months. And that is the sediment filter and the carbon filter.
Also, you need to change your RO membrane every year or so. Now, the filters are available between Rs500–Rs1000 based on which model that you purchased. But the RO membrane is extremely expensive. It’s about Rs2,500. Right? So, your ongoing cost for an RO water purifier on an annual basis will be anywhere upwards of Rs4,000. Compared to that, a UV-UF filter has much lower ongoing costs.
The UV filters need to be changed, again, in the same frequency, once in 6–7 months, but they are a lot cheaper. Since it does not have an RO membrane, the majority of the filtration cost is reduced. And UV-UF filters are also a lot cheaper than RO filters from an upfront cost point of view.
So, what do you do if you do not have a continuous supply of electricity or water in your area? Both RO, as well as UV filters, require a continuous supply of electricity and water for a period of time when it is doing its filtration.
If you have a continuous supply of over half an hour, so that should be sufficient to fill the tank of your RO or your UV water filter. If you do not have a continuous supply of water, then you might want to select a UF water filter which is typically gravity-based.
So, you fill the top tank, and then you get filtered water in the bottom tank.
How much time does the filtration take?
RO water purifiers are slower. They filter about 20 liters per hour, whereas a UV-UF water purifier filters at a pace of about 30 liters per hour. So, you may have also heard that RO wastes a lot of water. That is absolutely true. Almost 80% and upwards of water gets wasted when you are using an RO water purifier. And that’s the reason like I said earlier as well unless it’s absolutely required, you don’t need to purchase an RO water purifier.
There are no wastages when it comes to UV and UF water filters. These days, RO water purifiers come with almost a zero-wastage or a green RO water purifier. But really all they’re doing is collecting the water separately and saying that you can use that water for other things like washing vessels or for your plants.
Now, in my opinion, the concentration of salts is significantly high in that water and should not be used, especially for your plants.
Even for washing vessels, you may want to wash it using that, but in the end, you should make sure that you rinse it with water that is lower TDS. Definitely can be used for flushing, in my opinion.
what size of water purifier should you purchase?
Now, if you do have a continuous supply of electricity and water, the size of the water purifier does not matter. Because as soon as the tank is nearing empty, the water purifier refills itself. But if you live in an area where water supply and power supply is sporadic, then you might want to pick up a water purifier that has significant capacity compared to the number of people that are there in your house.
Assuming that each person of the family drinks 2–4 liters of water, if you have up to four people in your house, you at least need a water purifier of about 6–8 liters. Anything above that, you might want to pick a water purifier with an 8+ liter capacity. Now I guess Which Water Purifier is Best for Your Home in terms of size is clear.
Do water purifiers change the watercolor as well as the taste of the water?
Now, typically if you have hard water in your area, the water has a very funky taste. So, RO water purifiers do change the taste of the water, making it a lot better. Especially in areas where the TDS levels are higher. UV and UF water purifiers do not change the taste or the color of the water.
What are under-the-sink water purifiers?
Under-the-sink water purifiers are nothing but RO water purifiers that are placed under the sink rather than wall-mounted so that you can hide the water purifiers. They come with an extra tap for a water outlet right next to your sink. If you would like a comparison of an under-the-sink RO water purifier with a regular water purifier, drop me a comment.
These are the major considerations to be studied before thinking about Which Water Purifier is Best for Your Home.
So, to summarize, if you have hard water in your area and a TDS of over 200ppm, then you may want to go with an RO water purifier which also has alkaline and PH balance. If the water in your area is less than 200ppm, then a UV-UF combination is enough for your usage. Remember to factor in the cost of filter change and maintenance when you are purchasing your water purifier. I hope this was useful in helping you decide which water purifier to purchase.
