Whole House Reverse Osmosis System Buying Guide


Out of all the residential water systems present in the market, the whole house reverse osmosis system is the most expensive option. However, if a person is completely aware of the various benefits of this system, they would be ready to invest.


What Is a Whole House Reverse Osmosis System?

A whole house reverse osmosis system or RO system is a water filtration system that can efficiently filter out the entire home’s water. This is done through a reverse osmosis membrane. Usually, such a system is installed in the place from which water enters a house.


How Does a Whole House Reverse Osmosis System Work?

The whole house reverse osmosis system is installed in the entry point or the location where the water supply enters the home. This means that water flowing through the home of a person should first enter the reverse osmosis system. A whole house RO system works by supplying water through different filters. This even includes the semi-permeable reverse osmosis membrane.

Such a membrane is a key component in producing purified RO water. It even includes small pores that would block the contaminants from passing through. While the water particles are small and can pass through the membrane, the impurities present are too big. The more significant impurities are hence flushed down a drain along with some wash water.

The function of the whole house RO system is to produce purified water for the natural home of an individual. Water that enters from an appliance or faucet would always be cleaned through this system. Whole house reverse osmosis systems should always be on the bucket list if someone wants complete protection from waterborne contaminants.


Is a Whole House Reverse Osmosis System Necessary?

Manufacturers usually prefer to market their products in a way that would make any person feel like the whole house RO system is the best option. A person should first ask themselves whether they are looking for such a system. If they are looking for a simple water filter, there is no necessity of installing this system. But if there is a need for expanding the lifespan of water-based tech, then RO is a great option.

Other affordable options are available in the market, too, like the water softener or POE water filter. It is important to note that water from RO has a lower pH that is not always suitable at homes.

Advantages of Whole House RO Systems

Easy solution for the entire house: If the water supplied from the local area is poor, people should go for water treatment solutions for their whole home. This solution would meet different needs that include shower filter, under kitchen sink water filter. Such a filter is meant for protecting almost every appliance in a house.

Buying separate filters would require maintenance and installation costs. So instead, it is better to go for a reverse osmosis filtration system for the whole house. This new filtration system would efficiently cover everything in the house.

Better water taste: After installing this system, the customer would consume water from any faucet of their home. The water being supplied in every system is not just pure but would also taste good. This improvement in taste is mostly found due to the elimination of unnecessary contaminants.

Those who prefer to drink water from bottles can save money and drink it from the reverse osmosis system.

Effective option: There is no other whole house filtration system in the market as effective as Reverse Osmosis. These reverse osmosis systems can efficiently remove almost 99.9% of contaminants present in drinking water. Therefore, it is always the best option if there is a requirement for standard whole home filters.

Increased lifespan of appliances: Appliances of a household like dishwashers and washing machines might get affected due to sulfur and iron deposits. The whole house reverse osmosis system can clean the water and improve the lifespan of water-based appliances.

Improvement in hair and skin health: Using water that contains contaminants like calcium, manganese, and others can deteriorate the skin and scalp. Besides, it might prove more harmful if a person is lately suffering from any skin condition. A whole house reverse osmosis system would not just remove such contaminants from the water but also help maintain healthy skin and hair.


Disadvantages of Whole House RO Systems

Expensive option: Whole house reverse osmosis systems are considered the most costly water treatment option for residential purposes. Keeping aside the initial costs spent on making the purchase, the system also requires maintenance and installation charges. Changes in the reverse osmosis system like filter changes and replacement of essential parts are often needed.

This filtration system should not be purchased by those who do not tend to make long-term investments.

Might need pre or post-treatment: Whole house reverse osmosis systems usually require some pre-or post-treatment that would help protect them and maintain the water’s high quality. For example, if there is any need to install a water softener before the reverse osmosis system to prevent damage by hardness minerals, a neutralizing water filter is needed.

This neutralizing filter can efficiently remedy the high acidity and bring back the pH to neutral. A UV filter might be required if the customer wants to disinfect water that contains contaminants from the RO tank. Reverse Osmosis water is a more potent solvent than would grab onto impurities like dissolved metals.

Wastage of water: One can find several whole house RO systems in the market that are more efficient than under-sink alternatives. However, being bigger and treating so much water every day might lead to the wastage of water by the RO filtration system. Even the toilet water and bathwater of a household are filtrated through this system.

The exact amount of water being wasted by the system would depend on the household’s amount of water every day.

More space required: Under-sink reverse osmosis systems without a tank have started gaining popularity in the market. But it would not be feasible to purchase a whole house reverse osmosis system without any storage tank. This storage tank consists of a clean supply of water to the faucet whenever needed.

But the problem with the RO system is the space needed by it. Without enough space in a garage or basement, the reverse osmosis system is not of much use.

Needs adequate water pressure: A PSI of at least forty is required for operating a whole house RO filtration system. If the PSI is lower than this, then the user needs to purchase a pressure pump. This pressure pump would be responsible for boosting the pressure of the water at the POE. The process of reverse Osmosis cannot operate if there is inadequate water pressure.

If the water pressure is shallow, then enough water cannot be sent out through the filters. This is why it is advisable always to get the PSI checked.

Things To Consider Before Purchasing a Reverse Osmosis System

Before purchasing a reverse osmosis system, one must consider certain important factors:

Source water chemistry: Water composition, including its pH level and several contaminants, plays a vital role in affecting a person’s buying decision. Like if the water in a household is hard, they should first consider purchasing a water softener. This would help in ensuring that the system has a long lifespan and the RO membrane is protected.

Water with an unusually high or low pH can also damage the membrane. But this problem does not arise if the water is coming from a municipal source. Still, it is advisable to get the drinking water tests done in advance. These tests are essential in understanding whether an inline pre-filter needs to be installed or not.

Installing the sediment filter, for example, can help in protecting the reverse osmosis membrane.

Water consumption: There are several RO systems available in the market from which customers can choose. The size of the system would depend on the level of water consumption. The smallest reverse osmosis system is suitable for residential use. Daily consumption of water is important in determining the flow rate that would be suitable. This can be done either by handy calculation or by a smart meter.

The water consumption level would be vital in understanding the storage tank size needed. Larger reverse osmosis tanks are required mostly for commercial purposes like in laundries.

The pressure of water and flow rate: As was mentioned earlier, residential homes usually have a water pressure of 40 PSI. This is just the minimum pressure needed for any RO system to operate. But if the home has issues regarding its water pressure, there might be a need for a booster pump.

The booster pump would increase the home’s water pressure and ensure that enough water is being flown through the reverse osmosis system. The adequate pressure of water is helpful as it helps an individual use multiple water-based appliances simultaneously.

Usually, such booster pumps are connected with some power source. Instruments like a pressure gauge can be used too for measuring the pressure being exerted by the water.
