Antunes’ household water treatment systems are installed at the point of entry of your water supply, ensuring that all water in your home is filtered. Reverse osmosis residential water systems can also be installed at the point of use for drinking water, providing high quality water on demand.


When choosing water treatment for home use, the residential water purification systems you choose will depend on the specific contaminants present in your water. Consult with our water treatment professionals to help you identify the most suitable household water treatment systems for your home based on water quality testing and analysis.

For more detailed data on what’s in your pipes, order our test kit to get a comprehensive and professional analysis of your water and recommendations from a certified specialist.

When you understand the problems affecting your water quality, you can consider the other factors that play a role in choosing the right household water purifier, including water flow rate requirements, the number of people in your household, and the source of your home’s water supply. Once you have this information, you have the foundation you need to choose the best residential water treatment system for you.

Health and Safety:

Cleaning water helps remove potentially harmful contaminants that may be present in your water supply. These contaminants can include bacteria, viruses, parasites, chemicals and heavy metals. Drinking or using contaminated water can lead to various health issues, including gastrointestinal illnesses, respiratory problems and even long-term effects on your overall health. Which water treatment for home will remove these contaminants?


To remove microorganisms such as bacteria, viruses and parasites, you need a filter that has a small pore size capable of trapping them. The VZN residential water treatment system’s mechanical ultrafilter is tested and certified by the National Sanitation Foundation (NSF) for turbidity, cyst, and particulate class one reduction. It features ultrafiltration technology to remove particles as small as .015 microns (3,000x smaller than a human hair).

Chemicals and Heavy Metals:

Activated carbon filters are effective in removing many common chemicals, such as chlorine, chloramine, pesticides and volatile organic compounds (VOCs). Antunes’ whole home water treatment system removes these chemicals, so you have better-tasting, clean water going to all faucets in the house.

Antunes’ residential reverse osmosis system is particularly effective for removing heavy metals, including chromium, cadmium, lead, nitrate, copper and even fluoride. With a reverse osmosis household water purifier, your water passes through five stages of filters, ensuring that each contaminate is removed before it gets to you and your family. Antunes’ residential water systems with RO provide the highest-quality water and deliver it straight to your fingertips every day.


At Antunes, we design our technology to be compact enough to fit under any household sink. We aimed to create the best system available on the market today for your residential reverse osmosis needs. Our compact RO water treatment for home system is thorough in removing contaminants, so you can trust you’re giving your family the safest, freshest water possible every day.

Municipal Water Treatment Limitations:

While many municipalities treat the water supplied to homes, the treatment processes may not eliminate all contaminants. Water can pick up impurities as it travels through pipes, and the treatment process may not always be sufficient to remove all potential contaminants. Additionally, the quality of water can vary depending on the source, seasonal changes and other factors. Household water purifier systems provide an extra layer of protection.

Personal Preference:

Many people prefer the taste of filtered water over tap water due to the removal of chlorine and other chemicals used in water treatment. Residential water systems clean your water, improving its taste and smell, and making it more appealing to drink and use for cooking or making beverages.

Emergency Situations:

Residential water purification systems are especially crucial during emergencies or natural disasters when the water supply may be compromised. Natural disasters, such as floods or earthquakes, can contaminate water sources, making them unsafe to consume. Having a reliable household water purifier ensures you have access to clean drinking water when it’s needed the most.

Cost and Convenience:

Purchasing bottled water is expensive and environmentally unsustainable due to the production of single-use plastic bottles. Installing residential water treatment for home purification systems can save you money in the long run and reduce your environmental impact by eliminating the need for bottled water.
