The biggest advocate of the point-of-use drinking water system is the statement by the NRDC (Natural Resources Defense Council). According to them, “An estimated 25% or more of bottled water really just taps water in a bottle-sometimes further treated, sometimes not.”
Different studies have revealed that the genuine figure is more than 25%. This acknowledgment is the stand remark against bottled water. As a result, people are now cautious of buying bottled water as it is not safer than filtered water and damaging to the environment as a whole.
People who are trying to buy a point-of-use (POU) drinking water filter might encounter difficulty. However, they can easily pick one for themselves if they read out the below facts carefully. Before you buy this kind of system, you should know that you can keep it on or in a refrigerator, under the sink or on the countertop.
Aside from this, the complete opposite of POU is point-of-entry (POE). Basically, the POE water filtration system is all about attaching the filter line and it will filter water while entering the home. As a result, you will get pure and solid water for your home.
Let’s take a look at the important facts to buy the best point-of-use (POU) drinking water filter:
Price
Less than 10 cents a gallon, a POU water filter is able to produce better quality water than a bottled water system. Almost all the best water filters have a base price of less than $100. Now, if you are thinking about the prices, always consider how regularly you are replacing the filters.
A great quality system will only need replacement in every six months and it will have the capacity to filter around 10,000 gallons. Also, you should be careful while buying the small POU faucet-mounted filtration systems along with the water filter pitchers.
These types of units require frequent replacement. They give off an impression of being extraordinarily cost-effective at first, but you can still find better POU systems at a low- cost.
POU vs. POE
A POU unit can remove or reduce the contaminants just before you drink the water. This is one of the most important advantages of using a point-of-use system. Now, this advantage indicates that it is able to remove water-borne contaminants such as lead or vinyl chloride.
Keep in mind that lead or vinyl chloride can trickle into the water filter from the plumbing. In that case, the best alternative is to utilize both. Not to mention that a point-of-use system will always ensure the safest drinking water for use.
Performance
When you are thinking of the performance of a POU water filter, you have to consider the things – how many filtration technologies it uses, what is the overall micron rating, and how much filter media is used. Generally, this kind of system comes with either a multi-stage or two-stage filter.
A sink-connected to POU channel will not store as much filter media compared to a big countertop or under-sink water filter. The bigger surface region will produce a longer contact time for the water and ultimately, it will result in more successful contaminant removal. Another major aspect of performance is that how effective the POU unit is! It means the percentage of contaminants removed.
Usually, a top-class system will remove around 99% of chlorine. With that in mind, the best units will filter out contaminants of bigger than one micron in size. This is because all the best units have a sub-micron filtration system.
To put it simply, this kind of performance is effective as it can kill microbial life forms like – cyst parasites – giardia and cryptosporidium. Furthermore, you should be persistent in having a system with sub-micron filtration. It will allow you to have peace of mind while you drink cold filtered water.
Conclusion
Nowadays, people are becoming more aware of the fact that the dangers of chlorine and carcinogenic chemicals in public water supplies are imposing a greater level of threat to society. This is why people of all classes are feeling the need of high-quality point-of-use water. At the same time, people no longer trust bottled water as they believe they are not safe anymore.
For all these things, we recommend you to look for a point-of-use drinking water filter. It will offer you a 60-day guarantee and it is NSF certified as well. So, it will definitely bring much-needed safety to your life!
