What is the Whole House Water Filter?

A whole house water filter is a system that is capable of filtering water of the entire house. When we say ‘filtering,’ we mean removing all the impurities from the water and making it safe for household use. This system is also termed as the Point Of Entry (POE) system since it is connected to the main line before the water reaches your heater. Thus, this system filters both cold as well as warm water. As a result, you are delivered the filtered water every time you open a faucet. As a whole, the filtered water gets distributed to your kitchen sink faucets, bathroom faucets, showerheads, washing machines, etc.

Whole House Water Filter Buyer’s Guide

Now that you are familiar with what exactly the whole house water filter is, you need to consider some important factors before buying one. Take note that not all households need the same whole house water filters, even though all models operate in the same way. 

Here are a few factors to consider before choosing the right whole house water filter for your home:

Water Flow

With a variety of choices, different whole house filters are capable of producing different amounts of filtered water. In the end, the proportion of water entering your home and the filtered water coming out of the showers, appliances, and faucets will be equal. You should analyze the flow rate of the system according to the size and requirements of your family. For instance, a smaller household can use a water filter capable of producing around 10 gallons of water per minute. Likewise, you need a product with a better flow rate if you live in a medium to large family.  

Filters

This is another important factor to consider before buying a whole house water filter. As different filters are engineered to block different contaminants, you need to buy a unit that suits your water the best. You can have a clear idea of which product suits you the best depending on the results of water tests. If the result shows high heavy metal contamination, a unit with a copper-zinc mineral filter can do the job. However, if there is high bacterial contamination, you should look for the one with a UV filter.   

Durability

You should also consider the durability of the filter as some units require less maintenance than the others. You should change the filters timely for a better performance of your system. Not all filters used in a whole house system have the same longevity. Depending on your household water needs and consumption, you should look for a filter that offers good durability. 

Microns

You should choose the right micron rating for your filters, depending on the water testing results. A micron is a unit of measurement that is equal to one-thousandth of a millimeter. The best whole house water filters can block anything larger than 0.35 microns. In case you don’t have a highly-contaminated source, a 0.35-micron filter might not be necessary.

Consumption

You should also take note of your household’s water consumption before buying a whole house water filter. If your household uses a lot of water, you might have to change the filter once every month. This could make multiple cheap filter replacement costlier than fewer changes of expensive filters. If you want to buy the right kind of filter, balancing your household’s consumption with the filter’s longevity is a must.   

Budget

Well, this is probably the most significant thing you need to consider before investing in a whole house water filter. It is important to know how much your whole house water filter costs. There are tons of different models available in different price ranges. Basically, higher-capacity water filters tend to be more expensive than the lower ones. So, analyze your budget and make the purchase accordingly.  

Note: Don’t forget to add installation and maintenance costs when you plan to make a purchase.

Is the Whole House Water Filter System a Necessity?

Well, the straightforward answer to this query is ‘Yes!’ And there are plenty of reasons that support this answer. One of the main reasons why people look for the whole house water filtration system is the quality of water that runs through their household pipes. Though you are connected to the municipal water supply, the water that passes in your household can have an inclined quality. 

The water that runs through the pipes can be chlorinated. Although the chlorine works well to remove most of the bacteria and other microorganisms in the water, ingesting large quantities can be dangerous to your health. Besides, the chlorinated water can have bad effects on your hair and skin. These whole house water filters help to reduce the amount of chlorine that you are exposed to.

Another reason why you need whole house water filtration systems is that they are environmentally-friendly when compared to other different types of filters. 

Moreover, these types of water filtration systems do not produce wastewater. It means that all the water entering the system will filter out of it in the same quantity. 

Whole House Vs. Reverse Osmosis Water Filtration Systems

Don’t get confused! Both of these methods will provide you with fresh and clean water. However, the working mechanism of these filtration systems is completely different. 

The major difference between these two filtration systems is that a whole house filter system cleans the water as it enters your house. Meanwhile, the reverse osmosis system purifies water as it leaves the pipes

The whole house water filters are designed to treat water for general usages such as cleaning, bathing, and laundry applications. On the other hand, the reverse osmosis systems are engineered to desalinate seawater.

The reverse osmosis system uses a membrane rated at 0.0001-micron size as the main filter. On the other hand, the whole house system utilizes a filtration membrane, which is much larger than that of the reverse osmosis system. 

You can choose one among these systems as per your necessity. However, if you have hard water with a foul taste that also leaves residue behind, consider a whole house system in combination with reverse osmosis. When combined together, these systems ensure all of your house water is filtered properly, and your drinking water gets purified to the highest standards.

How Does a Whole House Water Filter Work?

Here are some of the major steps on how a whole house filter system really works:

  • Firstly, the system is attached to the main water line so that all the water entering your house will be filtered. 
  • As the water enters the filtration system, it will first encounter a sediment purifier. It is specially designed to remove the large particles in the water like salt, rust, sand, sediment, or debris.
  • The purifier also plays a vital role in keeping the next filters functional for a longer period of time. Without the sediment purifier, the other filters would require frequent changes. 
  • Once water exits the sediment pre-filter, it passes through the activated carbon filter. It plays a crucial role in removing an excessive amount of contaminants from the water. 
  • When the water gets out of the carbon filter, it passes through a copper-zinc and mineral filter. This filter removes the remaining contaminants in the water. Besides, it also does a great job at reducing the scale in the water.
  • Some models also include an additional stage where water passes through a softener or a descaler. In this step, the manufacturers use ion-exchange technology.
  • As the water enters an ion-exchange filter, it passes through sodium ions-filled resin beads. After the magnesium and calcium particles encounter the ion-filled beads, they replace the sodium ions, offering you softer water, which is a bit salty. There is an option to use a salt-free water softener to maintain the natural taste of the water.
  • Another optional component in whole house water filters can be the UV filter. This filter eliminates any remaining bacteria, viruses, or microorganisms that might have escaped the previous filters. Using a UV filter is beneficial if your water source has high bacterial contamination.  

Whole House Water Filter Systems Installation & Maintenance

The whole house water filter systems are not that difficult to install. If you can follow a few guidelines carefully, you are all set to go. Here are some significant steps you need to follow for proper installation of the whole house water filter systems:

  • First, turn off the main water supply and drain the system. 
  • Select the location for the filter and mark it. Keep in mind that you need to change the filters constantly, so choose a location that is accessible. 
  • Now cut the pipe with a pipe cutter. 
  • Install the compression unit and brass/plastic fittings as per the manufacturer’s instructions. Make sure to use Teflon tape on the fittings. 
  • Now install the filter with both ‘in’ and ‘out’ ports facing the right directions. 
  • Turn off the inlet valve of the filter and turn on the main water supply. If there aren’t any leaks, turn on the inlet valve and recheck for leaks. 
  • That’s it! The system installation is complete. Every time you need to change the filter, turn off the inlet valve and use the provided wrench to take out the cartridge filter. 

Now that you have installed the whole house water filter systems following all the guidelines, it is important to maintain them for retaining their performance strength. To maintain a filter system means changing the filter as per the necessity. Here are a few steps that you need to follow while changing a whole house water filter:

  • Turn off the water filter’s inlet valve.
  • Use the wrench to screw the filter off and keep a bucket close at hand to collect any dripping water. 
  • Clean the inside of the filter with a clean and dry cloth. 
  • Insert the new filter and tighten up with the filter wrench. 
  • Now turn the inlet valve on.
  • Allow the water to run for at least 10 minutes so that the filter activates before you use the water. 

FAQs About Whole House Water Filters

Usually, the average cost of setting up a water purification system in your home is roughly around USD 1,650. The actual price can vary depending on a variety of factors. While many can get a system installed in as little as USD 750, some may go up to USD 2,500.

The whole house water filter is engineered to remove contaminants from your water through a filter connected to your water line. For instance, the carbon filtration system is effective in removing chlorine, chloramines, odor, and VOCs to offer you chemical-free water throughout the entire household.

Yes! The whole house water filtration system tackles the water contaminants to deliver clean water from every faucet. While doing so, it slows down the flow of water. As a result, the water pressure decreases when it comes out of the shower, appliances, kitchen sinks, and all other home faucets.

If you fail to change the whole house filter as needed, it will lose its efficiency. The filter that is intended to trap contaminants can be clogged, or it could leak, and the pollutants can pass through the drinking water. On the other hand, home appliances and plumbing could get messed up.

For that, you need to conduct several water tests. Depending on the results, you can notice any of the following:

The water is chlorinated
The water has a high bacterial contamination
The water has a weird smell or taste
The water has small particles floating through it, or it is quite cloudy.

If you get any of these mentioned results, you should buy a whole house water filtration system for your household.

Conclusion

There you go! We hope this article has helped you make an informed decision about which whole house water filter suits you the best. Just note that the best whole house water filter is not equivalent to the most expensive one.
