It’s undeniable that water is one of the most vital elements we need in our daily life. You might get thirsty while working and you can’t drink the impure water directly coming from your tap.

So, you think of getting a purifier to ensure purity. Well, do you want a UV/ UF water purifier, or a RO purifier? Because drinking impure water can cause serious damage to your health. Let’s understand why you should get a purifier and which one is the best choice for you. Here’s the difference between water purifier vs reverse osmosis in a detailed guide.

Water Purifier vs Reverse Osmosis: What’s the Difference?

Obviously, you want to set up a purifier system in your home. But you want to be sure which one is perfect for you. And also you should make sure the money you are spending is really worth it. Then let’s understand the values of water purifier vs reverse osmosis.

Water Purifier Vs Reverse Osmosis

Water Purifier:

The water purifier has a kind of Method, UV, and UF water purifier. Before we get into more depth, let’s understand what water filtration or purifying means.

Water purification is a process to remove the contaminants that can’t be seen through naked eyes. However, water filters work on cleaning the smallest unwanted particle to purify the water enough so you can drink it without any hesitation to get sick.

Reverse Osmosis:

Reverse means the other way or the opposite. Osmosis means liquid or solute, which passes through the membrane from a highly concentrated soluble to a lower concentrated soluble. And Reverse Osmosis is just the opposite of that means it’s a process where solute passes through the membrane from a higher concentrated soluble to a lower concentrated soluble.

How Does It Work?

You know now what is water purification and what is RO. But aren’t you feeling a tingle inside to know which system works better and how it makes the water drinkable for you? And we’ll depict the efficient way that is suitable for you.

How Water Purifier Works

We already know that water purifiers have two types of filtration. Now let’s jump into it and learn how these two methods make the water clean so you can enjoy every sip of it and relax.

The water purifier sends the water into the filtration center where it breaks the water into small particles. Then it sends the water through a membrane and takes out all waste products that make the water poisonous.

How Water Purifier Works

Some purifiers have activated oxidized carbon, which separates the contaminants from water by adsorption. This is the purifying method of relatively bigger particles. Remember, bacteria and other toxic elements are still there in the water.

So to purify the water from these remaining, your Water purifier uses a UV filter if you get a UV purifier. Before reaching containers, a UV rod attracts the microorganisms that will harm you. And you get safe drinkable water.

How Reverse Osmosis works

Reverse Osmosis also passes water through the membrane, but water breaks down into molecules, unlike Water Purifier. The membrane filters are so small that water passes their molecule by molecule and reaches the container.

How Reverse Osmosis works

And its filter is so small that every element gets stuck in this and gets into the wastage bucket. It’s proven that 90% of the minerals get filtered out by reverse osmosis. And the water is safe to drink.

Moreover, no virus or bacteria can pass reverse osmosis unless it’s damaged. So as long as your RO purifier is alright, drink the purest water you can get.

Pros and Cons

You’ve already got an idea about a water purifier and reverse osmosis. And now, we’ve listed some pros and cons of them.

Water Purifier Pros
  • Cleans most of the dirt.
  • Uses UV rays to kill bacteria
  • Minerals don’t get affected.
  • Cheaper than an RO purifier.
  • A hassle-free installation
Water Purifier Cons
  • Fails to filter some gases at the molecular level.
  • Can’t purify alkaline water completely.

Reverse Osmosis:

We understand that a water purifier is popular but it doesn’t prove that reverse osmosis is far behind.

Reverse Osmosis Pros
  • Molecular-level filtration.
  • Filters every contaminant.
  • Great for alkaline water.
  • Durability is appreciating.
Reverse Osmosis Cons
  • Lacks minerals for the body.

Which One Should I buy?

Obviously, you are confused about what you should buy, that is why you are reading this. Now we will make it easier for you to make that decision.

If your water tastes too salty, that means your water is alkaline. You should install a Reverse Osmosis purifier because it makes the water acidic and pure enough to drink.

But if your water tastes sour, then it’s a little more acidic, so Water Purifier is a good choice for you. Because you won’t lose any important minerals, and you will have your health more secure.


However, there might be a debate between water purifier vs reverse osmosis. But you’ve already known both of the procedures that will help you to make a precise decision. It’s deniable that purified water is crucial for good health and proper functions.

So, whether the technique is to purify the water, you should ensure the purification before drinking. And before purchasing one, you should consider some basic features that are mandatory for purification.

Hi, I am Kyle Wood. I have a home gadget tools selling shop, where I sell different types of UV water purifier and saltwater UV sterilizer & its related accessories. Because of my business, I have to deal with so many clients of the UV water purifier and saltwater UV sterilizer users. I found many of my clients are facing difficulties with installation, maintenance, not getting the exact amount of service, and buying the wrong one. All those problems they face because of their lack of knowledge about these products.
