RO water purifiers are a must-have, with everything from beautiful lightweight versions to sophisticated features and more, and it's past time you replaced your old ones.

Reverse Osmosis (RO) water filtration is one of the most popular and cost-effective water filtration systems available if you're seeking great-tasting, fresh drinking water for your house or company.

In basic terms, a reverse osmosis water filter works by forcing water through a semi-permeable membrane and flushing impurities down the drain. A holding tank gathers the clean drinking water.

Why should you choose an RO purifier?

Enhances Taste

By eliminating impurities that cause flavor and odor concerns, RO filtering improves the taste, odor, and appearance of water. The flavor of the water, as well as the taste of the food we prepare in it, is influenced by contaminants.

When the taste of water is salty, or when it has a high percentage of Total Dissolved Solids (TDS) such as sodium, calcium, magnesium, potassium, and other minerals, a RO water purifier is highly recommended.

When the TDS level exceeds 200 ppm, RO filtration eliminates the extra TDS, softens and sweetens the flavor of the water, and leaves only clean drinking water behind.

Save Money

You may terminate your water delivery service and cease buying cases of bottled water if you have a RO system. For only cents per gallon, reverse osmosis filtration offers "better-than-bottled water" grade water.

Simple Maintenance

Because RO systems have few moving or replacement parts, they are simple to clean and maintain.

Removes Impurities

Reverse osmosis systems may remove nitrates, lead pesticides, sulfates, fluoride, bacteria, medicines, arsenic, and other contaminants from water.

The carbon filter in a reverse osmosis system will also remove chlorine and chloramines. Viruses, bacteria, fungi, and parasites may all be found in tap and groundwater, making them common carriers of disease-causing microbiological pollutants.

These impurities render the water unsafe for human consumption and may cause illnesses such as cholera, diarrhea, and typhoid.

As a consequence, experts advocate utilizing a RO water purifier to safeguard you and your family from these water-borne diseases by filtering out all of the potentially fatal toxins.

Removes Heavy Metals

Heavy metals can cause serious long-term health problems, including kidney, liver, and nervous system malfunction, as well as illnesses like cancer and lead poisoning. The most efficient technique to remove heavy metals and pollutants including iron, lead, mercury, arsenic, chlorine, and fluoride is through RO water filtration. A RO purifier filters out all physical impurities as well as microorganisms, ensuring that the water is completely safe to drink.

Effective water purification

When compared to only employing UF or UV filtration technology, RO water purification adds an extra layer of protection since it can remove even the tiniest chemical impurities that would otherwise bypass the other filtration technologies. When RO water purification and UV filtering are combined, the result is the cleanest drinking water possible, devoid of any pollutants.

Offers health benefits

Our whole health and well-being are improved by drinking RO cleaned water. It enhances digestive health, supports renal function, hydrates and energizes our bodies, and improves the quality of our skin and hair, among other things.

Buying Guide for an RO purifier

When it comes to purchasing a new water purifier, few people think about the finer points of selecting reliable equipment. The water supply is the first item to think about. If your water comes from a municipal corporation and your locality's TDS level is less than 250ppm, you may save money by using a simple gravity-based filter rather than a full-fledged RO (Reverse Osmosis) water purifier.

  1. If the TDS level is more than 250 ppm, a RO water filtration system should be used. Keep in mind, however, that not all RO systems are suitable for all types of water. TDS levels in certain cities may be as high as 1800ppm. It's critical to select a filter system capable of treating water with high TDS levels. As a result, understanding the TDS level of the water supply and how well-equipped the local municipality is should always be the first step in purchasing a water filter.
  2. Power outages are common, especially during the summer. So, wherever possible, invest in a high-capacity RO system to ensure that you don't run out of clean drinking water in the event of a power outage. If possible, choose a device with a filtered water storage capacity of at least 10 liters.
  3. When you examine the speeds of water purification systems, a lot of water is wasted in RO systems. When you install a RO water purifier, you'll notice that a lot of water is drained away to supply you with the highest quality water possible. On average, 4 liters of source water provide 1 liter of drinking water. So, if you want to save water, choose efficient models. Also, wherever possible, reuse the water discharged from RO systems for cleaning, watering plants, and other purposes.
  4. Consider the price of installation and maintenance. The majority of RO water filtration systems require routine maintenance as well as a one-time expert installation. Before purchasing a RO water purifier, always inquire about the installation technique, pricing, and service centers.
  5. Ensure that RO water purifier replacement filter kits are always available. Inquire about replacement filter kits before purchasing a new RO water filtration system, and see whether they are readily accessible in your area. The maintenance of a water filter has a significant impact on its performance.


Q1: Is it possible to connect a RO system to my refrigerator or ice maker?

A1: The incoming cold water line, drain, and an independent faucet are all connected to under-the-counter reverse osmosis equipment. However, a water treatment specialist may also connect a RO unit to your refrigerator and/or ice maker.

Q2: What is the maximum amount of water that a RO system can produce each day?

A2: Under-counter reverse osmosis tanks typically measure 12 inches in diameter and 15 inches in height. The reverse osmosis system will produce ten to 75 gallons (45-340 liters) per day at water pressure ranging from 40 to 100 PSIG.

Q3: How Noisy Is A Reverse Osmosis System?

A3: Although you may hear a "gurgling" sound when the "concentrate" or wastewater runs from the membrane to the drain, reverse osmosis systems are generally quite silent. The polluted concentrate is flushed away from the system by "crossflow" water in reverse osmosis.

Q4: What Is The Difference Between RO Water And Bottled Water?

A4: Reverse osmosis-filtered water is preferred by the majority of people over bottled water. The same technology that big bottling companies use to filter water is used in an under sink RO drinking water filtration system. Chlorine, chloramines, arsenic, pesticides, herbicides, and other contaminants are removed via reverse osmosis with carbon filtering. The elimination of these impurities not only makes the water safer to drink but also enhances the flavor significantly.

Q5: Is Investing in a Reverse Osmosis System Worth It?

A5: For a household of four, the cost of owning and operating a RO system is often less than 30 cents per day. From a financial standpoint, because most Americans spend $100 per year on bottled water, which equates to $400 per year for the home, a RO system would save approximately $300 per year because it costs around $100 per year to run. Pesticides, herbicides, chlorine, chloramine, and arsenic may all be removed by RO systems, making them well worth the investment.
