How Will I Define A Whole House RO Filtration System?
A Whole House Reverse Osmosis Filtration Unit is a system that treats the incoming contaminated water to convert it into safe and consumable water. No other filter process can clarify water as efficiently as a reverse osmosis filter.
Whole house systems work similarly to small countertop or under sink Reverse Osmosis systems but on a larger scale. It is designed to clean and supply large quantities of water to the entire household. They are known to remove up to 99.9% of contaminants.
How Does A Whole House RO Filtration System Work?
The workings of a Reverse Osmosis system are pretty scientific. It works on the principle that a Semi-Permeable Membrane (SPM) only allows water molecules to pass through. In other words, it’s an impermeable membrane for all other molecules except water.
Let us try to understand what ‘ Osmosis’ is first!
Osmosis is the movement of the solvent molecule (water in this case) across an SPM from higher concentration to lower concentration. Suppose you place an SPM in the center of a container containing dirty water on the left and clean water on the right.
As the water concentration is higher on the clean side, the water starts moving from right to left to maintain equilibrium. But, in the case of Reverse Osmosis, we apply pressure on the dirty water side to force water molecules to pass to the right side.
Thus, more and more clean water is extracted from the dirty water. This clean water is then collected or supplied to the main water pipeline of the house. All the unwanted contaminants and dirt are left behind the semipermeable membrane.
Now you will understand why a thick dirt layer is collected on the filter candles after a few months and needs replacement. The process is pretty simple but efficient.
How To Choose Whole House Reverse Osmosis Systems? [The Expert Buying Guide!]
Once you are sure you want a filtration unit for your home, the next question is how? We will answer exactly that in this section. Read ahead to make a well-informed decision.
1️⃣ Determine The Water Quality Of Your Locality
Before you even begin choosing a water filter, you should be well aware of the water quality in your region. The contaminant levels may vary depending on whether you receive water from the municipality or a private well.
A TDS meter can help indicate the total dissolved solids in your incoming cold water pipeline. The city water is usually chlorinated to remove germs and contains fewer water minerals. The water from a nearby well usually has high mineral content and heavy metal ions.
Hard water problems are prevalent. Water containing high quantities of Iron, Magnesium, Aluminum, and Calcium salts is known as hard water. These usually react with house pipelines and accumulate to cause havoc. Thus, it needs to be removed.
2️⃣ Find The Suitable Filter Media
Once you have a fair idea of how many impurities your water has, find the right type of water treatment filter. There are thousands of water filters available on the market. Carbon filters, RO filters, Cartridge filters, Sedimentation filters, Ion-exchange water softeners, and UV filters are the most common.
Sedimentation filters will be enough if the incoming water has lumps of mud, rock, and larger solids. Carbon filters are sufficient to clarify water containing dissolved dirt, mud, and silt. You can opt for activated carbon filters if your water contains microorganisms besides other dissolved solids.
In the case of various water contaminants, three to five-stage filtration will do the trick. UV filters are usually installed along with other units to kill germs by ultraviolet radiation. Ion exchange is a very efficient filtration process, especially for hard water, but expensive and high maintenance.
Now, coming to a Reverse Osmosis water filter that is both budget-friendly and highly efficient in removing a wide range of impurities and ions. Also, remember the goal you wish to accomplish with clean water.
If the water has to be used for drinking, sedimentation and carbon filter alone are not appropriate. When it comes to health, try going the extra mile for your family.
Either install a separate kitchen sink filter or an advanced technology whole house filter like RO for ultrapure drinking water quality.
3️⃣ Daily Water Consumption
Before you make the mistake of installing massive whole-house water filtration devices in your home, know your daily water requirement.
Calculate the amount of water required by one member every day and multiply it with the total number of members in the house. You will know approximately how much water is consumed in your home daily and what quantity of water filter you should choose.
Yes, water filters come in all sizes and capacities to suit your needs. The higher the filtration capacity of a water filter, the higher the flow rate. Usually, 300 Gallons of water per day is sufficient for a family of 3-4 members.
Water is used for several activities, including cleaning, bathing, washing clothes, drinking, etc. So, delays in water production will lead to inappropriate flow rates and time wastage.
4️⃣ Check For Standard Certification
Do you check for Hallmarks on your jewelry to check their originality? Well, something similar guarantees the safety of water filtration systems too. The National Sanitation Foundation, along with the American National Standards Institute, provides certification to Water Filter companies.
The water filter must pass strict tests and follow guidelines set by NSF and ANSI to gain accreditation and be certified as a safe filtration unit. NSF/ANSI certificate is essential to gain the trust of the customers and prove the efficiency of a filtration system.
Thus, we would recommend you give priority to NSF/ANSI-certified products while purchasing. It will give you a sense of surety and satisfaction that your family is consuming healthy water.
5️⃣ Whole House Reverse Osmosis Systems Cost
A significant factor for many families is the annual cost. Not everyone can afford high-end water filtration units. You spend a handsome amount of money purchasing the product. After that, you have to bear the installation cost and small but regular maintenance charges.
Maintenance costs vary from filter to filter. Some filters require regular cleaning to enhance their functioning, while some demand new filter media. Cartridge-based filters require filter replacement every 2 to 6 months. Ion-exchange filters need regular replacement of salt in their brine tank.
The price range of Whole house water filtration units starts from a few hundred dollars and can go up to a couple of thousand dollars. The price depends on the filter’s type, model, build, capacity, and size. Big brands charge big bucks in exchange for their services.
Almost every water filter comes with a DIY installation guide, but that does not mean you will be able to install it on your own. Hiring professional help is recommended to avoid any leakage or breakage. Plumbers are trained to make necessary alterations to the pipelines if needed.
6️⃣ Lifespan and Warranty
Every product has a different lifespan. In the case of water filters, the lifespan of the filter membrane housing and filter media is different. The filter media must be replaced after 2 – 6 months, depending on the water quality and usage.
A good Reverse Osmosis filter can last for 10 to 15 years, given that they are adequately maintained. They come with 2 to 10 years of repair warranty. Some companies also offer a 30-day satisfaction guarantee to their customers.
Remember to read the terms and conditions before claiming anything against the warranty. Some companies void your warranty if you have not installed the water filtration unit as per their instructions mentioned in the manual.
Whole House Water Filters vs Point-Of Entry Filters: Differences Explained!
Depending on the location of installation, filters can be broadly classified as Point OF Entry (POE) Filters and Point Of Use (POU) Filters. As the name suggests, Point-Of-Entry filters are installed at the very beginning of the main house water pipeline and thus provide clean water to the entire house.
Point-Of Use filters are installed at the sight of use. For example, the tap from where you will draw water. Kitchen sink and Countertop filters are types of Point-Of-Use filters, while Whole House RO water filtration systems and salt-based water softeners are types of Point-Of-Entry filters.
There is another crucial detail that many articles forget to mention. The POE filters make the water for drinking devoid of all the healthy minerals essential for our body. Water with calcium minerals and iron salts is good for your bones and blood.
So, here POU filters can come to the rescue. Sink RO systems come with a remineralization tank that puts all the essential minerals back into the water after the filter stages.
