What to know before buying a POU Drinking Water Filter?

Statement by the NRDC (Natural Resources Defense Council) is the most vocal advocate for point-of-use water systems. They claim that "an estimated 25% or more of bottled drinking water is tap water in a container-sometimes further processed, sometimes not". However, different studies have shown that this figure is much higher than 25%. This is the stand against bottled water. People are less likely to buy bottled water because it is more dangerous than filtered water, and can be harmful to the environment.

People can have difficulty buying a point of use (POU), drinking water filter. If they carefully read the following facts, they will be able to choose one. This system can be kept on or under the sink, on the countertop, or its own. Point-of-entry is the opposite of POOU. The POE water filter system involves attaching the filter line to the water source and filtering it while inside the home. You will receive pure water and solid water for your home.

Let's look at some important facts about buying the best POU drinking water filter.


A POU water filter can produce higher quality water than bottled water systems for less than 10 cents per gallon. Nearly all of the top water filters are less than $100 in the base price. When you think about the price, consider how often you replace the filters. A high-quality system will not need to be replaced for six months and will filter approximately 10,000 gallons. You should also be cautious when purchasing small faucet-mounted filtration systems. These units need to be replaced frequently. Although they appear to be extremely cost-effective initially, you can still find a better POU system at a lower cost.


The POU unit can reduce or remove contaminants right before you consume the water. This is one advantage of a point-of-use system. This advantage means that the system can remove water-borne contaminants like lead and vinyl chloride. Remember that lead and vinyl chloride can get into the water filter through the plumbing. The best option is to use both. A point-of-use system will ensure safe drinking water.


You need to think about the performance of a POU water filter. This includes how many technologies it uses, how high the micron rating is, and how much filter media it uses. This system can either have a multi-stage or a two-stage filter. The filter media will be stored less in a sink-connected POU channel than in a countertop or under a sink filter. A larger surface area will allow for longer water contact and, ultimately, will lead to more successful contaminant removal. Performance is also affected by how efficient the POU unit is. This is the percentage of contaminants that have been removed. A top-quality system will usually remove approximately 99% of chlorine. The best units can filter contaminants larger than 1 micron in size. All the top units have a submicron filtration system. This type of performance can kill microorganisms like cyst parasites, giardia, and cryptosporidium. You should also be consistent in obtaining a system that has sub-micron filtering. This will give you peace of mind when you are drinking cold filtered water.


People are now more aware that chlorine and other carcinogenic chemicals in public water supplies pose a greater threat to society. All classes feel the need for high-quality water at their point-of-use. People also don't trust bottled water anymore as they feel unsafe. We recommend that you look for a point-of-use drinking water filter to address all these issues. You will get a 60-day warranty and NSF certification. It will bring safety and security to your life.
