Clean water is our basic need. Unfortunately, in Toronto and Cambridge, the available water is not clean. It is hard water as it contains high levels of magnesium and calcium and sometimes has a lot of other contaminants.Â
It is a major problem, and it needs a solution. To clean the water, OAKS Wellness Water offers water filtration systems Like:

What is a Reverse Osmosis System and How Does It Work?
RO System is a point-of-use filtration system, usually an under-sink system used to clean the water for drinking and cooking.
It is different from pitcher or carbon filters, which are basic filtration portable devices. It is a water filtration system that works against osmotic pressure by using a semi-permeable membrane to clean the water, draining wastewater from it. It uses multi-stage filtration to remove different types of contaminants through different membranes.
What Factors Affect the Cost of a Reverse Osmosis System?
Capital Cost of Ownership includes the purchasing cost, installation, energy, consumables, maintenance, and labor costs. There are a lot of factors that affect the cost of the RO System:
- Types of RO System
- Number of filtration stages and system features
- Installation costs and labor requirements
- System maintenance, filter replacement, and long-term costs
- Certification, efficiency, and water quality
Type of Reverse Osmosis System
There are a lot of types of RO systems, on the basis of which the costs of the system vary:
- Under-sink (point-of-use)
Usually, an RO system is fixed under-sink, called a point-of-use, just used for drinking and cooking purposes. It costs $150-$300 for the basic unit without a tank, and for the more advanced system with more filtration stages, the cost rises to $1000.
- Countertop
A countertop RO system is a small system that typically costs $150-$500 varies depending upon its features. The under sink ro system cost for replacement filters is $30-$100 every 6-12 months.
- Whole-house (point-of-entry)
Sometimes, RO can be used for whole-house fixed at the point-of-entry of water and provides clean water in every tap. It costs almost $1000-$4800+ including installation, with prices over $2500.
Although the prices vary from system to system according to size and use, choose the best one according to your needs. A whole-house RO system could be costly, but you may choose it if you want to use clean water in every tap.

Number of Filtration Stages and System Features
There are different types of RO systems depending on their filtration stages and the quality of water they provide:
- 3-stage vs 7-stage systems
Some RO systems use just 3 filtration systems, while others use more than 3 and provide better quality of water.
- Alkaline & remineralization filters
Some RO systems use alkaline and remineralization filters that add essential minerals to water and give water a better taste and smell.
- UV sterilization
This adds a disinfection stage in the RO system to make the water biologically safe by neutralizing the viruses and bacteria present in the water.
- Smart monitoring features
Some RO systems also use some smart monitoring systems, i.e., automated filter alerts and TDS meters, to provide the best services of clean and healthier water.
The more filtration stages, the higher the cost is because more stages are added to remove different types of contaminants to provide better quality water, which is healthier and hotel quality.
Installation Costs and Labor Requirements
The installation costs vary depending on whether you DIY it, which will cost less, whereas if you hire a professional for installation, it would require labor costs too. If you want to fix it under-sink, you can fit it easily with guidance, but if you want to fix it at the point of entry, you need a professional due to the whole-house complexity.
The average labor cost to fix the system is $100-$300 for an under-sink system, and for a whole-house system, it would increase to $500-$1500 for a whole-house RO system.
It is recommended that it may cost a lot, but you should hire a professional to install it because DIY may cost less, but it has risks, i.e., water leakage, property damage, and system malfunction.
Maintenance, Filter Replacement, and Long-Term Costs
The RO system requires proper maintenance after a specific time. The maintenance period for filtration membrane replacement is 1-2 years, while the pump could last for 10-15+ years according to your usage.
The annual maintenance costs about $50-$80 annually for DIY, but for a professional, it requires an extra $100-$200 extra. Â The maintenance period also depends on water efficiency and wastewater. If your usage is more than usual, you need maintenance every 6 months.
The long-term costs are the initial installation cost and the costs of the pump and system after it malfunctions. The pump lasts about 10-15+ years, and for this purpose, you need $800-$1000.
Certifications, Efficiency, and Water Quality
The costs of an RO system also vary depending on its certification, efficiency, and build quality.
- If the systems are certified by NSF and ANSI, it means it will give you peace of mind and it will definitely give you better quality.
- The efficiency rates also affect cost because the better and more expensive ones give you 1:1 waste and clean water gallons, and a cheaper one provides 4:1 respectively.
- The water quality is dependent on the number of filtration stages present in the system. The more stages, the higher the cost is, and the better the quality is.
