In reverse osmosis, pressure is used to push water through a semipermeable membrane, which allows water molecules but not larger molecules like dissolved minerals to pass through. Clean water from the tap is isolated from the rest of the water supply by means of this method. This process effectively deconstructs water down to its elemental components. Many different types of contaminants, including bacteria, mercury, lead, fluoride, arsenic, nitrates, and sulfates, are removed from the water. Clean water may be made using tried and true techniques like reverse osmosis. The technology enhances the water's aroma, color, and flavor for the consumer. In comparison to other methods of water filtration, reverse osmosis is often recognized as one of the most efficient ways of purifying water.

Bottled water is typically cleaned by reverse osmosis, however, the process itself uses more water than a typical reverse osmosis plant. Water purified by a reverse osmosis system is as pure and has the same great taste as bottled water, but with far less of an impact on the environment. Reverse osmosis water filters are smaller than conventional water filters because they are installed beneath the sink, but they still require some storage space. If your sink has a garbage disposal, you should measure the space under it to make sure the filtration system will fit. 

Keep in mind that most home water filtration systems waste between 3 and 15 gallons of water for every gallon of filtered water supplied. It's important to remember that reverse osmosis machines operate solely on water pressure and not on power. In order to guarantee that the water in a home aquarium is fully free of human toxins and excess minerals, reverse osmosis systems are a worthwhile investment for pet owners who keep fish and/or coral.

Are you planning to buy an under-sink reverse osmosis system for your household? Its unique design and amazing water contaminant removal capabilities are worth going for. Remember that the price of an under-sink reverse osmosis water filter depends on different factors, including the brand, size, contaminants removal capacity, filter replacement, convenience, and others. 
On top of that, its initial cost is not the only thing you need to keep in mind. Annual maintenance costs must impact your buying decision. 

What is the Average Cost of an Under-Sink Reverse Osmosis System?

The price of an under-sink RO filter depends on the type of filtration process it provides and other features included, such as modular filter design, permeate booster or pump, and iron pre-filter.
Many under-sink RO systems feature a five-stage filtration process with or without a pump. The most innovative systems include extra stages such as remineralization and UV light sterilization. 
That being said, the average cost of an under-sink RO filter ranges from $200 to $500. The price of commercial under-sink RO filters ranges from $500 and may go beyond $1,000. 

⦁ Tankless under-sink reverse osmosis system cost 

Tankless under-sink RO systems come with a greater price tag. The price ranges between $300 and $600. You pay more for getting clean water instantly with this system than with tank-based systems. That’s because you don’t need to wait hours with this one to fill the storage tank. 

⦁ Under-sink reverse osmosis cost with tank

Under-sink RO water filters with a storage rank are often the traditional POU reverse osmosis systems. They often cost between $200 to $600. 

How Much is the Installation Cost?

Under-sink RO systems are challenging to install, but you can still hack them if you have some basic DIY skills. That’s a great option, especially if you’re on a tight budget or saving extra cash. But if you don’t have the skills, hiring a professional to install the system is important.

The average cost for professional installation range between $150 and $300. That cost applies when no modifications are necessary for your current plumbing. If modifications and repairs should be done, be prepared to pay for extra charges that can push the installation cost up to $400. 

Are There Maintenance Costs?

Yes, there are. Aside from the system's initial price, you must include the maintenance and operation costs. That cost is connected to the filter replacements and frequency of the membrane. The filter replacement depends on how you use the system and on the quality of the source water. For example, suppose your water is high in chlorine or sediment. In that case, you must replace the filters more often. 

Under-sink filters can last between six to twelve months. That indicates that you’ll have to spend money on replacement filters every six months to a year. Also, the annual filter replacement cost could range from $60 to $200, depending on the brand. 

Final Thoughts

An under-sink reverse osmosis system is certainly a great solution if you like cleaner and better-tasting water without contaminants. If you’re going for one, look beyond the initial cost. Consider the installation and the system’s maintenance cost to estimate the money you will be spending. Check out our store to purchase an under-sink reverse osmosis water filter for your home.
