UF (Ultra-Filtration) Water Purifier – Pros and Cons

The UF (Ultrafiltration) water purification process is similar to that of reverse osmosis. However, UF Filters use membranes with larger pores. But unlike other types of water purifiers, it does not require electricity to operate.

The UF Water Purifier can kill all bacteria, viruses, cysts, and other microorganisms in the Water. But it cannot remove dissolved salts from the Water. Only RO water purifiers can remove TDS from the Water.

How Does a UF Water Purifier Work? 

We’ll delve a little deeper now that we’ve learned the basics of a UF water purifier. In this article, we will learn how UF Water Purifier works. So, read the things mentioned below and help yourself.

How Does a UF Water Purifier Work
  • Separate Pollutants from Water: A semipermeable membrane is used in UF-based products to help separate pollutants from water-based molecules. Besides, the cleaner uses hydrostatic force to pressurize the Water to pass through the membrane.
  • Traps Microscopic Components: As a result, it traps all of the microscopic components and organisms. Moreover, you will get uncontaminated Water to drink. Although, these products can also keep the turbidity of the liquid intact for the same reason.
  • Energy Efficient: Furthermore, because no chemicals are used during the entire process, the water’s taste remains unaffected. As they do not require an electrical connection to function, UF purifiers are the most energy-efficient of all.
  • Unable to Remove Salt: The pores of a UF purifier are larger than those of a RO water purifier. As a result, it is unable to remove salt or other similar molecules in any way.

Types of Filters

A UF water purifier typically includes two purification filters: an activated carbon filter and a sediment filter. There are a few things you should know about these filters. 

Sediment Filters 

The sediment filter is located directly above the carbon filters. It usually assists the purifier in removing visible dust particles and other more significant components from the Water. However, the pores of this filter are quite large, and it will not be able to sort out the microscopic molecules. As a result, carbon filters are included in UF purifiers to address this issue.

Activated Carbon Filter 

In most OF the products, the activated carbon filter is kept above the lower compartment. Manufacturers commonly use wood, coal particles, and coconut shells to create this section. Moreover, they add some positive-charged ions to it. As a result, the filter can absorb chlorine-based contaminants and volatile organic compounds (VOCs) from your drinking water.

Working Mechanism- UF Water Purifier 

The water supply in the Ultra Filtration water purifier is filtered through a hollow fiber membrane. Besides, it solutes with a high molecular weight, and suspended solids pass through this membrane. Except for the particles’ molecular size, it retains, UF is mechanically identical to RO, nano, and microfiltration.

When To Use Ultra-Filtration Water Purifiers? 

UF water purifiers are ideal for those who prefer to leave some minerals in their drinking water. Moreover, people also want to get rid of the micro-contaminants inside the Water. However, due to no small amount of Water wasted many customers prefer the UF water purifier.

If your water is frequently regulated and contains few dissolved minerals, you can install a UF purifier at home. After purification, UF also recycles the extra stored water. Moreover, you can reuse the wastewater for irrigation or other purposes.

High-end Portability

Because there aren’t as many features in UF purifiers, they don’t  weigh much. As a result, you can easily pick them up from one part of your house and store them elsewhere. Besides, you can easily carry your purifier in a large bag to take it to other places.

Moreover, you can place it in the kitchen or anywhere in the house. With its help you can get clean and safe drinking water. It solves all your water related problems all at once.

Eradicates the Germ Cysts 

Step 1: To remove the germs’ water purifiers employ the coveted chlorine system. Nonetheless, cysts have a hard-to-break shell. Therefore, the chemicals face difficulty in penetrating them.

Step 2: Even if they kill the bacteria and viruses, they will not remove the eggs from the Water. Therefore, the Water that they filtered remains contaminated even after such a filtration process.

Step 3: So, how do you get rid of the eggs in your drinking water? You can always use a UF purifier to assist you because these specific purifiers can kill pathogens. Moreover, they remove their eggs by applying a high amount of water pressure to them.

Once the appliance finishes purifying the Water, you can remove the filters and wash them to remove the cysts.

Cleanses Dirty Muddy Water 

Ultrafiltration purifiers can clean muddy or turbid water. Moreover, it removes all germs, cysts, turbidity, and dirt, which UV water purifiers cannot.

  • Removes Dirt: The UV Water Purifier cannot purify clay or turbid Water. Because the mud and dirt in the Water protect the germs from the UV Rays. Therefore it renders the process ineffective.
  • Remove TDS From Water: Heavy Metals and Dissolved Salts such as Arsenic, Cadmium, and Lead are present in public or municipally supplied pipe water. Therefore, when the TDS levels in the Water increases, you will need a reverse osmosis water purifier.

Excellent Purification 

Some water purification systems use chlorine treatment. However, the eggs (Cysts) have a tough shielding shell that the Chlorine chemicals cannot penetrate. Therefore, the Germs’ DeaGerms’es and active Eggs are not filtered out of the Water.

But UF Water Purifiers removes 

  1. Chlorine resistant eggs (Cysts) of Amoebic disease 
  2. Gastroenteritis parasites like Giardiasis and Cryptosporidiosis 


The Ultrafiltration Purifiers are indestructible and do not produce impure Water. Moreover, UF Water purifiers are incredibly durable and will not crack. Therefore, it allows contaminated Water to pass through.

The worst that can happen to the UF Water Purifier is that the flow of Water will obstruct. Although, you can easily clean the filter to maintain the flow of water. Therefore, it becomes easy for you to get a water purifier of your choice. It will help you get clean and safe water, thereby resulting in good health and surroundings.


You’ve seen it haven’t you? products based on UF technology are incredibly cost-effective. Are you curious as to why? For instance, they are usually less expensive than both RO and UV purifiers.

  • Basic Features: 

The main reason for this is that these types of purifiers typically employ some basic techniques. It helps them to remove impurities from your drinking water. Therefore, they don’t have any advanced or trendy features like 

  1. pH correction
  2. Alarms
  3. Revitalizers
  4. Digital Panel
  • Effectiveness: 

Overall, if you have to choose between a RO, UV, or UF water purifier, the UF product would be the better choice. Although, it depends on the water source at your place. You can choose either one according to your preference.

As a result, if you clean them regularly, they will serve you for a long time. The worst thing that can happen to the product is that the water flow is reduced or blocked. However, using the previously mentioned method, you can easily maintain it.

No Wastage of Water

According to recent research on the availability of drinking water, only 1% of pure Water is currently available worldwide. The rest is either ocean-based or saline, both of which are unfit for human consumption. Therefore, in this dire situation, wasting Water is not a good idea.

However, nearly every water purifier wastes at least a small portion of the Water while purifying it. But the UF products are known to be the most effective in this situation. Because it does not throw away any water during the process, but it can automatically separate water molecules from dust and dirt.

Disadvantages: Ultrafiltration Water Purifier 

The UF water purifier’s only drawback is that it cannot remove dissolved salts from the Water. 

  • Heavy Metals and dissolved salts can only be removed from Water using RO Water Purifiers.
  • As a result, UF and UV Water Filters are only recommended if you get your water from a public or community source. River, well, and rain-harvested Water are all compatible with UF Water purifiers.
  • So, when using the UF Water Purification system, make sure the TDS levels are good, and the Water is free of toxic elements. For example, arsenic, cadmium, lead, and other toxic metals.
  • If you’re conyou’re about the TDS levels in your water, you can use the RO water purifier at your home.


Unlike a few others, UF purifiers usually use a necessary purification technology to rid Water of all contaminants. However, it is incredibly efficient and performs flawlessly in almost all situations. So, if the TDS level of the Water in your area is low, a UF model could be an excellent option for you.

This type of purifier is considered the best option for removing viruses and bacteria from your drinking water. Furthermore, they are quite effective at removing a few metalloid-based water contaminants.

However, they are not as effective as RO water purifiers when dissolving toxic elements like salts. UF purifiers perform admirably in other situations, particularly when it comes to eliminating harmful microbes.
