RO UV Water Purifier Advantages (Benefits)
Benefits of RO UV water purifiers are:
Broad Contaminant Removal
RO UV water purifiers provide the most thorough filtration results seen among home water filters.
Reverse osmosis removes up to 99% of heavy metals, salts, chemicals, sediment, and more, while UV light stamps out any waterborne microorganisms.
Highly Effective Water Disinfection
In an RO UV system, reverse osmosis first removes floating particles making the following ultraviolet disinfection process even more effective. As such, the UV light eliminates as much as 99.9999% of microorganisms in the water.
Healthy Drinking Water
Undoubtedly, RO + UV purification leaves your water healthy and safe to drink.
Pristine Taste
Although UV disinfection does not improve water taste, RO filtration certainly does.
Any Odors Removed
If your water smells terrible, RO UV purifiers can change that. They remove odor-causing chemicals etc., leaving your water odorless.
No More Bottled Water
Many homeowners buy bottled water because their home water is not safe.
Using RO UV makes tap/well water safe for drinking, so you no longer need to spend money on expensive bottled water.
No Chemicals Used
RO UV water purifiers do not add chemicals to your water at any point. One less thing to worry about.
Easy to Install and Maintain
Most RO UV systems are under sink units and easy to install. If you know a little plumbing and have the essential tools, you can install one in about two hours.
Maintenance is no big deal either; you just need to replace a few parts on schedule. Change the pre-filters every six to twelve months, the UV bulb once a year, the quartz sleeve every two years, and the RO membrane every three to five years.
Customizable
If you have specific standards you’d love your purifier to meet, you can achieve them by customizing it. For instance, if you want to add an additional remineralizer to your system, all you need to do is buy standard-sized parts from reputable brands and connect them.

RO UV Water Purifier Disadvantages
RO UV purifiers are not all good without bad. Here are the downsides that come with using them:
RO Wastes Water
Reverse osmosis wastes up to 5 gallons of water per gallon of purified water. So if you use an RO UV purifier, you’ll waste a lot of water, and this will reflect on your utility bill.
Fortunately, you can combat this con by using a booster pump; it significantly reduces the amount of wastewater the system produces (by as much as 90%)
Loss of Essential Minerals
RO removes a wide range of water impurities, but that also includes useful minerals like potassium and magnesium. So RO filtered water usually lacks essential minerals.
On the bright side, you can add safe minerals back to your water after purification by using a remineralizer.
Slow Filtration
Reverse osmosis is a slow process. That’s why RO systems usually come with a storage tank to save the water for later use.
Space
You’ll need enough space under or near your kitchen sink to install a point-of-use filter system. Whole house setups require dedicated space in your garage, basement, or a utility room.
Second Faucet
Apart from space under the sink, POU RO UV water purifiers also require an extra faucet on the countertop. If your sink does not have an extra hole for a tap, you’ll need to drill it.
Drain
You must arrange to drain the wastewater from your RO UV filter. That means connecting the system to your sink’s drain pipe. This is not a significant disadvantage, but it’s an additional thing to look out for during installation.
By the way, the same applies to whole house systems.
What Is an RO UV Water Purifier and How Does It Work?
An RO UV water purifier is a filtration system that uses reverse osmosis and ultraviolet light to eliminate water impurities.
- First, the system filters water by pushing it through pre-filters and an RO membrane, which removes a broad range of contaminants.
- Then, the system uses UV light to kill any leftover microorganisms.
RO UV water purifiers leave your water contaminant-free and healthy!
