Buying Guide – Things To Consider Before Buying
Reverse osmosis systems are available in plenty and diverse designs and varieties. You’ve seen a variety of such options above, so make that step to select the best. However, even when the best systems are presented to you, it will be complex to choose the right one if you don’t know what to consider.
1. Cost And Budget
One crucial consideration those buying RO filtration systems should consider is the cost of the filters and their budget. Reverse osmosis filtration systems are available in prices ranging from 150 dollars to about 8000 dollars.
Advanced RO filtration systems include high-end features like auto flush, re-mineralization, automatic shut on and off functions, and lots more. You will also get some RO systems that have essential elements for adding nutrients and better taste to your water.
Never settle for less if you wish to get value for the investment you make. Buying a RO system on the lowest price-range only risks you getting a low-quality product that won’t serve you for long. Compare top brands and get a product that has tons of excellent client reviews and ratings.
2. Size Of The RO System
Regardless of where you want to install the RO water filtration system, get one that doesn’t take up the entire kitchen spacing.
Look out for a compact but efficient water filtration system that fits well in the available kitchen counter or under-sink spacing. It’s advisable to measure the available kitchen spacing and try searching for a system whose dimensions match the provided spacing.
Returning a filtration system to get a replacement takes time and money, and I am sure you wouldn’t want to deal with such inconveniences. Check out with the product’s customer care support to help you select a water filtration system that meets your kitchen spacing requirements.
3. System’s Ease Of Use
The system you buy should be personalized to simplify ease of use. Since the system will be used on a daily basis, it should have a simple design that allows for easy use.
Your loved ones want a RO filtration system with easy to change filters. Even if you are a stay-at-home mom or dad, you wouldn’t have all the time to clean a water filtration system daily. That’s why you should settle for a water filtration system that is simple to clean and maintain. It would be even better if you settle for a system that has an automated cleaning cycle.
4. Amount Of Water Wasted
One common issue with RO systems is that they aren’t 100% efficient as they waste lots of water. It’s angering to understand that most RO systems can only recover an optimal of 15% of the purified water. While the dispensation of wastewater helps ensure the delivery of clean drinking water, getting a system that wastes lots of water only adds up to your daily expenditure. That’s true since more electricity is used to power the filtration processes while more water is dispensed as waste.
The good news is there are tons of high-end water filtration systems that can dispense clean drinking water and minimal wastewater. Look out for such systems if you want your experience using RO water filtration systems to be a fun and lucrative one. A system that has an eco-friendly certification will be a good bet as it doesn’t release lots of wastewater.
5. Type Of RO Water Filtration System
Reverse osmosis water filtration systems are sold in two main options; commercial and residential. There are lots of differences between systems made to be used in residential settings from those made to be utilized in industrial areas.
Commercial-grade RO water filtration systems have powerful water dispensation features while those for residential areas dispense water at lower rates. The high-pressure water rates help to ensure that enough water is filtered to meet the increased demand. The pressure rating for a commercial RO system ranges from 100 to 250 PSIG.
The performance of any of the two systems is widely dependent on the built-in membrane and the water source. Whichever water filtration system you decide to buy, always keep in mind that commercial-grade water filtration systems are costlier.
That’s because they have additional features such as fuel gauges, electrical supplies, monitors, and pumps. Commercial-grade water filtration systems can only be installed on the wall, floor, or frames while residential-grade systems are designed to be installed under the sink.
6. The System’s Effectiveness
Reverse osmosis systems are rated differently when it comes to effectiveness. The efficiency of these systems usually depends on the type of filters used and the number of stages the water is passed through.
Systems with more filtration systems include more features for removing contaminants such as sand, chlorine, and dirt. It’s always best to settle for systems with more than five stages since the more stages water is passed through, the purer it comes out.
Check the performance rating of the reverse osmosis water filtration system online. Customer reviews will significantly help you in making a more informed purchase decision.
7. The Amount Of Water Filtered Per Day
Different RO filtration systems have varying efficiency rates. The amount of water a system can filter in a single day depends on the size and brand.
Checking out the system specs and technical details will help you better understand how much water a system can generate in a day. The standard sizes common with the majority of water filtration systems include 100 gallons, 80, and 50 gallons.
In case you have limited kitchen spacing, it would be good to go with a 50-gallon water filtration system. In case you have a bigger spacing, you may need to consider a reverse osmosis water filtration system that can efficiently pump about 80 gallons or more a day.
8. Ease Of Installation
Different water filtration systems come with different manuals, instructions, and video instructions. Whatever RO system you choose, you wouldn’t want to pay an extra penny to get it installed in your office or house.
There are advanced water filtration systems that have easy to understand installation guides and compact designs that allow for simple installation. Whether the installed is designed to be installed under the counter, on the wall, or counter, it would be great you get a unit you can easily install on your own without needing to use specific tools or have any plumbing skills.
9. System’s Estimated Lifespan
All RO water filtration systems have different lifespans. There are those designed to last for years before they need to be replaced.
A RO water filtration system lifespan is dependent on a variety of things including but not limited to the construction, brand, and the durability of the features.
Always search for water filtration systems that have strong and durable filters. You should as well search for a brand that is reputed and reliable.
Find a water filtration that comes with warranties and money-back guarantee. I am sure you wouldn’t want to purchase a system that will give you a hard time repairing it soon after the purchase, and that’s why I advise you get a system that includes an active warranty and money-back guarantee.
10. Filtration Quality
Find a RO filtration system that uses the latest technologies. A system with semipermeable membrane and other pre-filters will be a good deal as it will help eradicate all the toxic elements and compounds.
The majority of RO filtration system brands boast of eliminating about 99% of water contaminants. Since it may not always be true, using a TDS meter to examine the systems efficiency rate is recommended.
For anyone who doesn’t know, a TDS is a total dissolved solids meter that works to check the quality of the filtered water in comparison with that in the source. Other essential considerations to help you tell the abilities of a water filtration system are WQA and NSF certifications. Products certified by these organizations are always the best as they meet the set quality standards.
Frequently Asked Questions About RO Filtration Systems
Here are most of the commonly asked questions regarding reverse osmosis technology and systems.
-
What Is RO?
RO stands for reverse osmosis- a renowned water filtration technology that involves removing a majority of water contaminants by pushing water through a semipermeable membrane under pressure.
-
What Is The Difference Between RO Water And Distilled Water?
Reverse osmosis water is very different from distilled water – but both are safe to drink. In general sense, mineral water refers to water that has been purified, treated, and bottled for drinking.
Mineral water is usually naturally enriched with minerals right from the source: live streams, springs etc. It does not require any form of purification. Most of the water that we get from the store isn’t necessarily from these sources, though. But it has been purified and minerals added.
Reverse osmosis water, on the other hand, is water that has been passed through semi-permeable membranes to get rid of most of the contaminants.
This membrane eliminates chlorine, metals, bacteria, and other forms of impurities thereby making it absolutely safe for drinking.
However, keep in mind that that most Reverse Osmosis water treatment systems also remove minerals from the water. The good news is that some of the latest models in our best reverse osmosis systems reviews above are engineered to retain the minerals. -
How Does Reverse Osmosis Filtration System Work?
Assuming that you already understand what reverse means, let’s remind ourselves what osmosis is. Osmosis refers to the natural movement of molecules of a solvent from a less concentrated solution to a solution that has a higher concentration through a semipermeable membrane.
In reverse osmosis, it’s the opposite that happens. Water molecules move from a solution of water contaminants leaving you with pure drinkable water on one side and most of the contaminants on the other side.
Since reverse osmosis goes against the principles of osmosis, energy in form of pressure has to be applied to make it a success.
That’s why reverse osmosis filtration systems utilize a pump that pushes the contaminated water through a special semi-permeable reverse osmosis membrane. -
Is It Healthy To Drink Water Filtered Via RO Systems?
Reverse osmosis is a world-wide water filtration technology widely known for its efficiency and reliability. Water filtration systems that employ this technology dispense the purest and cleanest water ever.
