How to select the best reverse osmosis water filter: A Buying Guide?

Well, you might wonder how difficult it can be to buy a water filter. You can go to the online shopping platforms, pick a brand and place an order.

However, the method is much more crucial than this, there are many other important factors apart from the brand that you must consider while you are selecting the best reverse osmosis water filter.

Of course, you can’t entirely rely on the salesperson as they can be manipulative instead of helpful. Now, are you wondering how will you know what are the important factors? Don’t worry! Following are some of the most important factors which you must consider before buying one:

01. Water Quality:

This is the most important factor which you must consider before buying a water filter. The water that is supplied to your house has different sources, the first thing that you should do is check where your drinking water is sourced.

Next check the level of TDS or Total Dissolved Solids in your water, as the TDS will measure the dissolved combined content in your water. The content can be in any form such as micro-granular suspended, molecular, or ionized forms.

According to WHO it is best to drink water that contains a TDS level of 50 to 120 ppm and a pH of more than 7.4. Besides, your water might also contain other inorganic compounds like sulfates, chlorides, bicarbonates, etc. In that case, you will need a RO or reverse osmosis filter to remove those content.

02. Contamination:

The factor that you must consider next is contamination. The water delivered to your house contains many heavy metals, which commonly include magnesium, arsenic, iron, copper, and lead. If your water contains these metals in large quantities, it can be extremely toxic and harmful to your health.

In fact, it is also noticed that the water often carries industrial wastes along with it. RO or reverse osmosis can help you remove all these harmful particles from your drinking water. Go for a reverse osmosis water filter that purifies your water by using ultraviolet (UV) technology. It will help you in removing harmful particles, without removing the essential minerals from your drinking water.

03. Water Pressure:

Next, consider checking if the water pressure of your water source is high. This factor will help you determine whether you should consider buying the product or not.

Remember, a good reverse osmosis water purifier system will not only work well in high water pressure but also where the water pressure is comparatively low. Some brands also recommend using a booster pump attachment to the RO system for houses with low water pressure. However, to stay on the safer side, go for a water purifier that can take the pressure of 5 to 40 pounds per square inch or psi.

05. Daily Usage:

Before buying a water purifier you must get a rough idea of the quantity of water that is consumed in your house. Decide if you want to use your water purifier just to purify your drinking water only or for other works in your house.

After you find out the requirements and consumption of water, you can select the model accordingly. If the consumption and requirement are high buy a model with high power. It is suggested to buy a water purifier that can fit well in your family.

06. Portability:

We often miss considering this factor while we are shopping for a water filter. However, it is also important to see if the water filter is portable or not. You won’t buy a water purifier every now and then, make sure that you can take your water purifier in case you need to move from one place to another.

Thus, it is best to look for a water purifier that is portable, sturdy, light weighted, and can be shifted according to your convenience. However, don’t ignore the looks of your purifier as it will enhance the beauty of your kitchen. So, bring home the one that looks good and is portable as well.

07. Electricity:

Most of the purifiers that are available in the market work on electricity, however, it can be a problem during power cuts, as it won’t work if there is no electricity.

However, there is a system that uses activated carbon filters or an ultrafilter to purify your water without electricity, but such filters can only remove sediments from your water. Thus, the best thing to do is to buy a water filter that can work with or without electricity.

08. Budget:

Now as you know your requirements, consumption, and preferable purification technology, it is very important to set a budget for your product. Make sure that you bring home the one which is compiled with the latest technology that too on a budget as it won’t upgrade itself like your smartphone.

Set a budget and spend on a reliable brand for your water filter. It is suggested not to get influenced by any external sources and get the one that provides the best facilities at a reasonable price range.  

09. After-sales maintenance services:

The after-sales services provided by the brand are very important. You must go for a brand that provides quality after-sales services for your water filter. Maintenance is an essential part especially when you deal with a home appliance like a water filter.

They need constant maintenance in order to work for a long time. Thus, before you buy a water filter, look for the cost of services required by your product and judge if it is worthy or not. Go for a water filter from a brand that offers once in a year of free or cheaper maintenance facilities.

As now you have gathered enough information about the same, you might think of buying one for your home or office, but you are not very sure of which one to get. So, to help you out with that, here is a list of some of the best reverse osmosis water filters in India.

What is reverse osmosis?

Reverse osmosis is a technology that is used to remove impurities from drinking water. It uses a very unique method, where the water goes through the higher concentration side of the RO membrane to the less concentrated side in order to provide purified drinking water, and the intensive water that is left after the process is known as brine or waste.

By using osmosis the water is purified as it goes through the membrane to obtain equilibrium on both sides.

For example, if pressure is applied to a huge amount of hard or salted water while the water is getting purified in an osmosis water filter, the salt remains on the other side of the membrane and you only get clean drinking water.

How does a reverse osmosis system work?

By now as you know that a reverse osmosis system can purify water in a pre-filter process before the water is passed through a semipermeable membrane. Later, it goes through a post-filter by existing from the RO membrane, before making entry to a dedicated faucet.


A reverse osmosis system works in different stages. Basically, a RO membrane is the most important factor in a reverse osmosis system, however, there are different types of filtration. A RO system is made up of 3, 4, or 5 filtration stages.

You will find a sediment filter and a carbon filter along with such water filters. These types of water filters are pre-filters or post-filters, which depend on the water that passes through it, before or after the water passes through the membrane.

All types of reverse osmosis systems contain either one or more than one of the following filters:
