Clean drinking water is essential—not optional. But with so many types of water purifiers available, choosing the right one for your home can feel like decoding a science textbook. RO, UV, Gravity—what do they mean? Which one’s best for your water type?
If you’re feeling overwhelmed, don’t worry—you’re not alone. At Aquifer India, we’re here to help you understand the differences and make the right choice for your health and lifestyle.
Let’s break it down, plain and simple.
Why Do You Need a Water Purifier?
Even clear-looking tap water can hide harmful contaminants. Depending on where you live, your water might contain:
- Bacteria and viruses
- Heavy metals like lead, arsenic, or mercury
- High Total Dissolved Solids (TDS)
- Chemical residues and chlorine
- Sand, rust, and other sediments
Boiling isn’t enough to remove these impurities—and that’s why water purifiers have become a necessity, not a luxury.
What is an RO Water Purifier?
RO (Reverse Osmosis) purifiers use a powerful semi-permeable membrane to filter out the smallest of impurities from water. This includes salts, chemicals, heavy metals, and even microbes when combined with other technologies.
If your water supply is hard (from borewells or tankers), contains a high TDS level, or tastes salty, RO is your best bet. It not only purifies but also improves the taste and color of water.
However, keep in mind: RO purifiers require electricity and waste some water in the process. That’s why many modern RO systems come with TDS controllers or water-saving tech, like those offered at Aquifer.
What is a UV Water Purifier?
UV (Ultraviolet) water purifiers are designed to disinfect water by killing bacteria, viruses, and other microorganisms using UV light. They don’t change the taste or remove dissolved salts—but they do eliminate harmful germs instantly.
UV systems are ideal if your home gets treated municipal water or water with a low TDS count but you still want to make sure it’s microbiologically safe.
Since they don’t alter the mineral content of water, UV purifiers are a great option for those who want a germ-free but mineral-rich drinking experience. They do need electricity, but consume very little power.
What is a Gravity Water Purifier?
For those living in areas with low TDS water and a limited budget, gravity-based water purifiers are a smart and simple choice. These purifiers use the force of gravity—no electricity required—to filter out sediments, bacteria, and some chemical impurities using activated carbon and UF (Ultra Filtration) membranes.
Gravity purifiers are especially useful in rural areas, small towns, or homes without regular power supply. They’re easy to use, low-maintenance, and portable.
However, they’re not suitable for water with high TDS or heavy contamination. If your water is visibly dirty or has a salty taste, a gravity purifier alone may not be enough.
So, Which One Should You Choose?
Let’s simplify it even further:
- Go for RO if your water tastes salty, has high TDS, or comes from borewells or tankers. RO purifiers remove chemicals, heavy metals, and excess salts—making them ideal for hard water conditions.
- Choose UV if your water looks clean but you want to eliminate germs. Perfect for homes using municipal water or treated sources with a low TDS level.
- Pick Gravity if your water supply is soft, you’re in an area with no electricity, or you need a budget-friendly, portable option for everyday use.

Quick Tips Before Buying
Here are a few things to keep in mind before making a purchase:
- Test Your Water: Know the TDS level and whether microbial contamination is a concern.
- Check for Certifications: Ensure the purifier meets national and international water safety standards.
- Think About Maintenance: RO systems need filter changes every 6–12 months. Gravity and UV purifiers are easier to maintain.
- Consider Your Budget: RO is usually more expensive, while gravity purifiers are very affordable.
- Match It to Your Lifestyle: Small family? Large joint family? Your usage matters when choosing capacity and flow rate.
