Pure Water Appliance Costs

How Do Pure Water Appliances Work?

There are four main types of pure water appliances that you can choose from: countertop filters, reverse osmosis systems, UV sterilization, and distillation. Each of these has its advantages and disadvantages, depending on your water quality, usage, and budget. Let’s take a closer look at each of them.

Countertop Water Filter 

Countertop filters are the simplest and most affordable type of pure water appliance. They are easy to install and use, as they attach directly to your faucet and filter the water as it flows through. They can remove chlorine, sediment, and some other common contaminants from your water, improving its taste and odor.

However, countertop filters also have some limitations. They have a limited capacity, meaning that they can only filter a certain amount of water per day. They also require frequent filter changes, which can add up to the cost over time. Moreover, they are not very effective in removing heavy metals, pesticides, bacteria, viruses, and other harmful substances from your water.

Reverse Osmosis Systems

Reverse osmosis aka RO systems are the most advanced and effective type of pure water appliance. They use a high-pressure pump to force the water through a semi-permeable membrane, which filters out up to 99% of contaminants, including fluoride, lead, arsenic, nitrates, and microorganisms. They also have a storage tank and a faucet, which provide you with a constant supply of pure water.

RO systems can be installed either as whole-house systems, which filter all the water in your home, or as under-sink systems, which filter only the water from a specific faucet. Whole-house systems are more expensive and require more space, but they can protect your plumbing and appliances from corrosion and scale. Under-sink systems are cheaper and more compact, but they only provide pure water for drinking and cooking.

UV Sterilizer 

UV sterilization is a type of pure water appliance that uses ultraviolet light to kill bacteria and viruses in your water. It is usually combined with other types of filtration, such as carbon or sediment filters, to remove other contaminants as well. UV sterilization is very effective in eliminating pathogens, such as E. coli, salmonella, and giardia, from your water, making it safe to drink.

However, UV sterilization also has some drawbacks. It does not remove any minerals, chemicals, or dissolved solids from your water, which can affect its taste and quality. It also requires electricity to operate, which can increase your energy bills. Moreover, it needs regular maintenance, such as replacing the UV bulb and cleaning the quartz sleeve, to ensure its optimal performance.

Electric Distiller 

Distillation is a type of pure water appliance that uses heat to boil the water and then condense the steam into pure water. It is one of the oldest and simplest methods of water purification, and it can remove almost all contaminants, including salts, metals, organic compounds, and microorganisms, from your water.

However, distillation also has some disadvantages. It consumes a lot of energy, which can make it costly and environmentally unfriendly. It also removes all the minerals and trace elements from your water, which can make it flat and bland. Furthermore, it requires regular cleaning and descaling, as the impurities left behind can accumulate and damage the appliance.

Cost Comparison

The cost of pure water appliances can vary widely, depending on the type, features, and functionalities of each option. Here are some estimated price ranges for each type of appliance, based on the average market prices as of December 2023:

Appliance Cost Range 
Countertop Water Filter $20 – $150 
Under-sink RO System $250 – $750 (installed)
Whole-house RO System $2,000 – $7,000 (installed) 
UV Sterilizer $300 – $800 
Electric Distiller $200 – $1,000 

These prices are only for the initial purchase of the appliance and do not include the additional costs of installation, filter replacements, and ongoing maintenance, which can also vary depending on the type and frequency of use of the appliance. For example, countertop filters may require filter changes every 2-6 months, which can cost $10-$50 per filter. RO systems may require filter changes every 6-12 months, which can cost $20-$100 per filter. UV sterilization may require bulb changes every 12-24 months, which can cost $50-$100 per bulb. Distillation may require cleaning and descaling every 1-3 months, which can cost $5-$10 per cleaning.

Therefore, when comparing the costs of pure water appliances, you should consider not only the upfront cost but also the long-term cost of ownership and operation.

What Are the Key Factors to Consider?

Choosing the right pure water appliance for you depends on several factors, such as your water quality, water usage, budget, maintenance, and additional features. Here are some questions to ask yourself before making a decision:

Water Quality

What are the common contaminants in your local water supply? You can find out by checking your water quality report, which is usually available online or by request from your water provider. Alternatively, you can test your water yourself using a home water testing kit, which can be purchased online or at a hardware store.

What level of filtration do you need? Depending on the type and amount of contaminants in your water, you may need a different level of filtration to ensure your water is safe and healthy. For example, if your water has high levels of chlorine, sediment, and taste and odor issues, you may be satisfied with a countertop filter. However, if your water has high levels of fluoride, lead, arsenic, nitrates, or microorganisms, you may need a more advanced option, such as an RO system, a UV sterilizer, or a distiller.

Water Usage

How much water do you use per day? You can estimate your daily water consumption by multiplying the number of people in your household by the average amount of water used per person per day, which is about 2-3 gallons for drinking and cooking. Alternatively, you can measure your water usage by checking your water meter or your water bill.
