  • Their potential disadvantages before making the purchase.

In this article, you will get all you need to know about the point of using water treatment systems.

At the end of this guide, you’ll be satisfied with complete information on its different aspects.

What Are the Point of Use Water Filter (POU)?  

It can install at locations for water access (often bathrooms and kitchen counters) point of use systems produce pure drinking water. 

Its capacity is less relative to the point of entry water system and is, therefore, most suitable for use at a single point of connection with a low amount of usage. 

The system is best to make alkaline water, as well as bathing and cooking. 

Point of use systems needs regular maintenance with replacement of filter cartridge after each 3 to 6 months, or as much as an entire year, based on the dimension of the unit selected. 

Some varieties are available for point of Use systems, such as carbon filtration and reverse osmosis (RO) which remove most water contaminants. 

The result is high-quality clean water from your contaminated water.

How is Point Of Use Water Filters Used?

POU water filters are a great option to protect patients actively and reactively when responding to waterborne challenges or positive samples of waterborne pathogens and an outbreak. 

In the United States, they should consider when creating and modernizing water management plans that should meet CMS Memo 17-30-Hospital/CAMHs/NHS* and ASHRAE 188* guidelines.

As of March 2020, point-of-use filtering is preferred to control water according to ASHRAE 12-202020*.

If the POU filter is classified as an FDA 510(k) class II medical Device*, it should use it following its instructions to use

The requirements for using a POU filter are different for manufacturers. Ensure that the requirements are adhered to prevent risk and liability.

Advantages of Point of Use Filters?

Instant Access

A point-of-use water purifier can supply as many Gallons of water as you need. 

When you switch on your faucet, water infuses into the filter, passes through it, then leaves the filter at a rapid rate. 

The cold water you drink is pure and high-quality purified water. 

It makes point-of-use water filtering systems more attractive than water filters on countertops, such as pitchers that require refilling regularly.

More effective than water pitchers, refrigerators filter  

For a substitute for your water pitcher or refrigerator filter, Point-of-use water filters are the better choice. 

Refrigerator and pitcher filters may enhance the smell and taste of your water, but they don’t do much as effectively as a point-of-use water filter. 

Point-of-use filters can be made employing advanced methods of filtration like reverse osmosis and carbon water purification.

They will provide delicious tasting and clean water that’s free of the common contaminants in tap water.

Easy Installation

Although, you’ll need to be pretty handy to set up a point-of-use house water filter.

It’s as straightforward as any DIY project, and usually, there are many clear and easy instructions to follow. 

Installation is different based on the hard water treatment system for the point of use you decide to install.

Countertop systems connected directly to your faucet tend to be simpler to install than a POU system under the kitchen sink.

Diverse Filtration

For point-of-use, water filtration systems do not have a specific design, style, or collection of features.

Most POU systems use reverse osmosis water filters to remove more than 99.9 percent of TDS (total solids dissolved) present in water. 

Certain are less efficient but excellent in what they do.

They can mix carbon filters with other efficient techniques for filtration and boost water quality.

Lower cost than the whole-house system.

One of the main reasons people opt for point-of-use systems instead of whole-house systems is the cost. 

Point-of-use UV filtering is less costly than whole-house systems since it can only filter water from one tap.

No need for bottled water

POU water filter provides better water quality so that you will not need to purchase bottled water in the future. 

The water will be fresh, smell nice, appear clean, taste good, and be safe to drink.

So you’ll be able to save money and drink only from your kitchen faucet when you want.

Systems for Specific needs

If you think of a typical point of use drinking system for water, you think of an under-sink water filter. 

While these systems are the most famous-after however, there’s a wide range of other options also. 

Berkey shower head filters, for instance, can be effective in removing water contaminants that cause issues while showering, such as hard water minerals, iron, and sulfur.

What are the Disadvantages of A Point of Use Water Filter?

Does not deal with shower water

The exposure of people to contaminants in tap or well water through drinking. 

Certain contaminants, such as chlorine and chloramines, can be equally harmful if you breathe them into water vapors in the shower. 

A point-of-use water purifier does not solve this problem.

Only offers one source of pure drinking water

Point of Use Water Filter

Since a point-of-use device only filters water at one faucet, all other tabs within your home will have contaminated water.

It means that you can only drink high-quality water from just one source within your home.

Can be costlier if multiple are purchased

Perhaps you’re considering buying a point-of-use filter to go with your sink in the kitchen; however also desire to have fresh, chlorine smell-free, cold water for your shower. 

In that scenario, you’ll need to put in an activated-carbon filter separately from an under-sink reverse osmosis device.

It could save money in the long term to invest in a POE home water treatment system that can work throughout your house.

Won’t protect your appliances, plumbing, or pipes

As opposed to a complete house filtering system, a point-of-use filter cannot treat water before it travels through the pipes of your home. 

It means that it cannot tackle contaminants that can clog your pipes or damage appliances that use water.

Still require frequent maintenance

If you are analyzing a POE whole-home solution with point-of-use filtering systems, POE systems can be similarly demanding in terms of maintenance. 

For example, a single RO in your apartment device requires sediment and a regular carbon filter cartridge (usually between every six months or a year). 

RO system also comes with a filter membrane that must change every two years or more.

A majority of POU sink systems have at minimum one filter media that you’ll need to change to ensure the highest filtering quality.

Point of Entry or Point of Use: Which Filtration System is Better?  

Both treatment systems have distinct advantages, and each isn’t better than the other. 

Which one you choose, points-of-entry or point-of-use relies upon your needs and budget. 

The main difference is that a point-of-use system can use for just one faucet or tap. 

If you’re seeking to purify your water for drinking purposes to improve the taste, a reverse osmosis softener could benefit you. 

Installing the same system in the entire house would cost a lot of money, and you might not need high-purity water for clothes or dishwashers. 

We can fit the latest POU technology over the kitchen faucet to enhance the flavor. 

Advanced systems utilize an underground storage tank beneath the sink and filters installed on the wall behind.

In the event of a point-of-entry system, possibly located at the source of the water supply, every faucet, and tap within your home will receive purified, filtered water. 

It could be beneficial if your supply line sources are well water containing heavy metals or chemicals that smell. 

It’s well-known that hard water causes streaks of stains, residues, and discoloration on kitchen utensils, clothing, bathtubs, and showers. 

Every water source must receive filtering water from home water treatment in such a situation.

In most instances, both of these systems are required and need to be put in place at the appropriate levels.

Point of Use or Point of Entry Water Filtration System Cost

The water filters used by households utilize a combination of chemical and physical methods to eliminate or minimize the presence of waterborne contaminants.

However, certain types require the first expenditure. Knowing the cost of each can help you make an informed choice before you purchase. 

Costs for water filters are based upon these factors:

Cost of filtering system

The answer to this question is that it’s all in the details. It is possible to purchase a top-quality under-sink water filter for under $100. 

However, if you’re interested in the whole house water system, it could cost you $500-$3,000

Do not let the cost discourage you, however. Water filtration systems can be affordable; as we showed the reasons.

Installation cost  

In terms of installation, prices can be wildly different. 

A POU system is typically simple to install and can be placed beneath a faucet in the sink and even on countertops. 

However, POE systems are installed at the main water source within your home. Professional installation might be necessary to install these systems. 

The installation price of a house water filter will differ based on the level of detail; however, on average, an entire house filter will cost between $872-$2,768 and average approximately $1800

It can be costly, which is why it’s essential to consider this expense.

Maintenance costs

In evaluating the cost, you must consider ongoing maintenance for various systems. 

When you need replacement filters, it will depend on the kind of system you have and the filter media. 

Certain models require replacement filters every two to three months, while others will last for years.

Does Point of Use Water Filter the Right Choice for You?  

If you want to protect yourself from your brown well water, then a point-of-use system is a fantastic option rather than an appliance filter or small pitcher filter. 

It can provide you with better and cleaner water than the two alternatives, and make sure that you can filter the water you use to wash your dishes from the kitchen sink.

A point-of-use system can be more affordable than a whole-house system, which is why it is an ideal option if the whole-house option doesn’t meet your budget. 

If you’d prefer filtered water at each faucet in your home and protection of your plumbing equipment and appliances, a full home system is the best ideal choice.



When Should I Use a POU Water Filter?

There are many reasons why a point-of-use Reverse Osmosis filter could be the best option for you. A few of the influential factors are:

  • You’re on a budget, and your choices are restricted
  • Your skin is sensitive, and hair and the most significant issue to your drinking water’s quality are the levels of chlorine, so you’re looking for an individual filter that can get rid of this harmful substance from the water in your shower.
  • Would like clean, readily available treated water.
  • Your water does not have excessive hardness; it doesn’t have significant levels of sulfur, iron, and other pollutants that can create aesthetic issues within your home.

If you’re still thinking about the possibility of water filtering products, you should have your water tested before deciding whether or not to tackle it. 

Once you’ve figured out the various kinds of contaminants in your water, you’ll be able to pick the most appropriate solution to meet your needs.
