Clean drinking water is as crucial as inhaling pure air. The increasing water pollution pose serious threats on our life causing health complications, skin irritation and much more. And hence, we need water purifiers to stay healthy and keep our family healthy. They ensures safe and healthy drinking water for our families. However, choosing the best suited water purifier can be a daunting task. If you are stuck with several water purifier options available in the market, this guide will help you make an informed decision while buying a water purifier.

In this guide, we will go through all the important factors you must know while buying a water purifier. Let’s start with the different water purifier technologies available in the market. Each of them has its own strengths and weaknesses.

Different types of water purifiers
1. Reverse Osmosis (RO) Purifiers
RO water purifiers are the most recommended ones. RO stands for reverse osmosis. To understand what reverse osmosis is, we first need to understand its process. In this process, water flows from an area of low solute concentration (low TDS level) to an area of high solute concentration (high TDS level) through a membrane (appx. 0.0001 microns). However, reverse osmosis is exactly the opposite of this. In this process, water molecules from higher TDS level flow to the lower TDS level. That is why RO water purifiers are best for metro cities and areas with high water TDS.

2. Ultrafiltration (UF)
The next type of water purifier is Ultrafiltration, which also uses a semi-permeable membrane to purify water. However, unlike ROs, UF purifiers have larger pores (approximately 0.01 microns), and hence, they are not suitable for areas where water TDS is high. They can only remove undissolved solids and larger impurities. One advantage of using UF purifiers is that they don't require electricity to function, and hence, they are cheaper to run.

3. Ultraviolet (UV) Purification
As the name suggests, Ultraviolet (UV) purification uses ultraviolet rays to purify waters. In these purifiers, water flows through high-intensity UV rays, which kill or inactivate bacteria and viruses that are harmful to our health. However, UV purifiers cannot remove any dissolved or undissolved impurities from water. Therefore, UV water purifiers are only recommended for areas where the water source has a low TDS level.

Which water purifier is the best?

RO technology has become synonymous with water purifiers. However, buying the best water purifier depends on factors like the source of water and the TDS level of input water. RO water purifiers are best suited for areas with high TDS levels. According to the Bureau of Indian Standards (BIS), the maximum TDS limit for safe drinking water is 500 ppm.

Since we discussed TDS a lot, let's understand what it is and how TDS level in water is considered safe.

What does TDS in water stand for? How much TDS level is suitable for drinking in water?

TDS stands for total dissolved solids, which indicates the amount of total dissolved impurities, whether organic or inorganic. The substances bigger than 2 microns in size are termed as dissolved solids. The maximum TDS level in water that is advised by BIS is 500mg/litre. If the water TDS level is more than 1000mg/litre, drinking is not safe. TDS level less than 300mg/l is advised as pure water.

How do RO water purifiers work?

The RO purifiers force the water under pressure through a membrane with approximately pores. 0.0001 microns. The dissolved solids in water, which are smaller than 0.0001 microns, pass through the membrane and are free from TDS. It compiles several stages, including the sediment layer, carbon filter, RO membrane, and post-carbon filter, ensuring the water reaching you is impure-free.

Now that you know everything about the different categories of water purifiers, how they work, and how much TDS level is suitable for drinking, there are a few more factors that you must consider while buying a water purifier.

Additional factors that are must to consider

1. Understanding the water quality: Before buying a water purifier, examine the water supply quality of your area. You can consult a local water quality report to determine the level of impurities. Then, you can make a choice based on that.

2. Set a budget: Water purifiers come in a range of prices and a realistic budget will help you narrow your choices.

3. Know what features you need: These RO water purifiers come with a range of additional features, and many of them might not be important to you. Although the more, the merrier, the pricing will also be influenced by these features. Hence, based on your budget, look for important functionalities like filtration stages, storage capacity, mineral retention, and ease of maintenance.

4. Brand reputation and service: It’s always good to buy water purifiers from trusted brands known for their quality, customer service, and warranty programs. Investing in RO water purifiers means you’re investing in your and your family’s health.

To make your work easier, we have also listed some of the best RO water purifiers available today across different price categories.

A good speaker isn’t just about volume; it’s about rich sound, deep bass, and clear vocals that bring every beat, word, or explosion to life. Whether you're looking for a portable Bluetooth speaker for travel, a home theater setup for movie nights, or a smart speaker for voice control, choosing the best one can be overwhelming with so many options out there.

That’s why we’ve put together this speaker buying guide. Instead of getting lost in tech jargon and endless product listings, we’ll break things down in a simple and practical way. From understanding sound quality, wattage, and connectivity options to choosing the best size, brand, and features for your needs, this guide will help you make an informed decision.

Why should you take the time to pick the right speaker? Because great sound makes a difference—whether it’s enhancing your work-from-home setup, leveling up your parties, or simply making your daily routine more enjoyable. A poor-quality speaker can leave you frustrated with muffled audio, weak bass, or constant connectivity issues, so making the right choice matters. Here are all the key factors that you must consider before making a choice.

Speaker Buying Guide: Types of speakers

Let's begin with different types of speakers.

1. Bookshelf Speakers

Compact yet powerful, bookshelf speakers are great for small to medium-sized rooms. They are designed to sit on shelves, tables, or dedicated stands, delivering high-quality stereo sound. Perfect for music lovers and home theater setups, these speakers strike a balance between size and performance.

2. Floorstanding (Tower) Speakers

Tall, powerful, and packed with multiple drivers, floorstanding speakers are ideal for audiophiles and those seeking a rich, room-filling sound. They work well as part of a home theater system or a standalone music setup, offering deep bass and clear mids and highs.

3. Soundbars

If you’re looking for a sleek, space-saving speaker to enhance your TV audio, a soundbar is the way to go. These long, slim speakers are perfect for improving dialogue clarity and adding depth to movies and shows, often coming with wireless subwoofers for extra bass.

4. Home Theater Speaker Systems

For a true cinematic experience, a home theater speaker system includes multiple speakers, such as a center speaker, floorstanding or bookshelf speakers, surround speakers, and a subwoofer. These systems create a 360-degree surround sound experience, making them ideal for movie enthusiasts.

5. Smart Speakers

Larger rooms may require floor-standing speakers or surround sound systems, while smaller spaces work well with compact bookshelf or wireless speakers. Additionally, consider room treatments like rugs, curtains, and acoustic panels to minimize reflections and improve sound quality.

4. Power Source and Portability

Decide between wired or battery-powered speakers. Wired speakers offer consistent power and better sound, while portable Bluetooth speakers are great for moving around the house or outdoors.

5. Budget and Brand Reputation
