Reverse Osmosis System Buying Guide – Features To Look

Water is an essential part of life, and in such a case, it is important to buy a filter that meets your needs. You can refer to the points listed in this section to make an easy choice while buying the reverse osmosis system. Considering these points will help you in ensuring that you buy something that meets your requirements. Check out these points in the buying guide now –

The capacity of Filter–The first thing to check is the amount of water that the Reverse Osmosis System can filter daily. This is defined in terms of the gallons per hour, and you need to ensure that your family gets enough water every day. You need to consider the number of family members as well while making this choice. 

The efficiency of the RO– One thing that we hate about Reverse Osmosis System is the amount of water that is wasted in the Reverse Osmosis System. A lot of water is drained directly because the RO system usually has an efficiency of 50%. Consider the amount of wastage in the system and see if you can reuse the wastewater to water the plants or for washing clothes.

Minimum Pressure Required– Water pressure is an important thing for the Reverse Osmosis System. You need to check the minimum requirement of the water pressure for a particular Reverse Osmosis System. You also need to check the average water pressure at your property. If the pressure at your property is lower than the minimum pressure then you might need to install a booster pump as well. Do not forget to check this factor while buying Reverse Osmosis System.

Storage Compartment– Check if the Reverse Osmosis System has a storage compartment as well. This will store the water for you, and you would not have to turn on the system every time you need the water. Opt for something that can store at least 5L of water. You will come across a lot of models that can store anywhere between 3L to 7L water.

Source of Water– You can also look at the source of water and see if the Reverse Osmosis System is compatible with it or not. If you have hard water, then you need to check if the Reverse Osmosis System can support such type of water. If you are getting the water supply from the municipality, then you might not have to worry about the type of Reverse Osmosis System that you are buying.

Mineralization of Water– The problem with Reverse Osmosis System is that they will demineralize the water and hence you do not get the daily mineral dose that you need. In such a case, you can check if the Reverse Osmosis System can re-mineralize the water for you. Also, check how often you would need to replace these mineral cartridges. This can make the water healthy.

Replacement of Filter– You will have to change the filter components as a part of maintenance. You need to check the life of the filter and the process to change the filter. A lot of brands have now made the Reverse Osmosis System, where the end-user can replace the filter without any help. This makes it easy for the end-user, and it also reduces the maintenance cost.

Cost of RO and Cost of Filter– The next thing to check is the cost of the Reverse Osmosis System and while you are checking the cost of the Reverse Osmosis System, you can also check the cost of the filter. This will refine the recurring costs that you are going to incur during the lifetime of the Reverse Osmosis System.

Warranty– Check for the warranty offered by the brand that you are opting for. The standard varies from 1 year to 5 years. Usually, the price is proportional to the warranty so you need to take a call here. Some brands may also provide a free annual maintenance package for a year with every purchase. In such a case, the brand selection is important as well.

Ease of Installation– See how easy it is to install the Reverse Osmosis System. Can you install it yourself? Is the brand offering free installation? Check all these factors, and you will understand if you would need to spend extra on the installation as well.
