In case you want more complex and powerful systems, you may end up spending more than $10,000. Installation costs vary between $0 and over $500, depending on the amount of plumbing work.

Factors Which Influence the Price of a Whole Home RO System

There are numerous variables which influence the price of an RO system. We have taken into consideration the most important of them.

Size and Dimensions

Simple systems, whether countertop or under the sink, have the lowest prices. For around $200 or less, you can purchase an item to connect to your kitchen tap.

Whole-home reverse osmosis systems have to cover the needs of an entire household. The technology behind them is more complicated, and they occupy more space. It is not a wonder that the more robust have prices that exceed $12,000.

Tip for Buyers: calculate the amount of water you use before deciding on a specific size for your RO system; for home use, just multiply the number of people in your household with 75, which represents the gallons of water an average American consumes per day.
 

Another critical parameter is the flow rate, which shows the gallons of water produced per minute. If its value is too low, you will have to face pressure problems.

The size of a whole home RO system also depends on the number of hours it runs per day, water temperature, and the percentage of total dissolved solids.

Number of Components and Features

All reverse osmosis systems function on the same principles. The larger ones have more components because they serve a whole residence, a farm or a small business.
 
Most standard home RO systems have the following main parts, each with its subcomponents.
 
The Pre-Filtering System may consist of one or more filters. Most machines have a special filter which separates the sediments from the liquid. The presence of a carbon filter is also common. These components have the purpose of protecting the membrane against particles, dirt, and chlorine.
 
 
The Reverse Osmosis Unit has an inlet through which the water enters the device. The pump generates the pressure needed for the liquid to pass through the membrane. This holds back more than 98% of the impurities present in water.
 
 
The Tank is a depressurized place where the purified liquid is kept. There are two float valves which maintain the water at a suitable level.
 
Not all systems have this feature. Households with reduced water consumption should take into consideration the RO devices without a tank.
 

The Repressurization System consists of a pump and an under-pressure tank.

The Post-Filtering System has in its composition one or more carbon filters. They eliminate any possible taste from the purified water.

The Control Panel which allows humans to access commands and supervise the device.

There are RO units which have recycling valves, float balls, flow meters to measure purified and wasted water, automatic flush, bypass valve, an antiscalant system, and spectraguard pumps.

Stages of Filtration

Regarding the filters, most specialists agree that four should be enough to remove all harmful substances.

Tip for Buyers: test your water first and then purchase additional filters.
 
The alkaline filters are not compulsory for the reverse osmosis process. They release in the purified water the useful minerals lost during the reversed osmosis.
 
Plus, they diminish the level of alkalinity in your water. The calcite filters increase the pH levels lowered by the action of the osmotic membrane.

Costs Related to Installation and Maintenance

A Whole-House Reverse Osmosis System is not a simple tap which can be installed by an amateur. To make sure that the connections to the water network and plumbs are solid, you should call an authorized plumber or a contractor.

Remember that the filters and the membrane do the hard work. For this reason, you will have to replace them. Professionals claim that a filter functions at its full capacity for six months.
