Best Gravity Based Water Purifier In India (2022) – Expert Reviews

There are several great options available for the best water purifier in India. One such is gravity-based. Best Gravity based water purifier in India leverage gravity for making water safe for drinking.

These types of water purifiers are sometimes also known as UF purifiers, where UF stands for ultra-filtration.

Beyond the usual techniques of water purification, such as boiling and chlorination, popular water filtering techniques include gravity-based filtration, ultraviolet filtration, reverse osmosis, and ultra filtration.

Working & Buying Guide Of Gravity Based Water Purifier

To be able to make the best gravity based water purifier in India selection, you need to first understand how gravity-based water purifiers work. The subsequent section covers the same.

Working

Unlike UV water purifiers, gravity-based filters don’t rely on electricity for water purification. Instead, these water filtering units use activated carbon or activated charcoal. It is a processed form of carbon having small, low-volume pores.

In gravity-based filters, water moves from a higher point to a lower point. Here, water purification happens due to the effect of gravity, hence, the name. That’s why, you need to add water from the top of a gravity-based water purifier and receive purified water from the bottom. A typical gravity-based water purifier has:

• A microfiber mesh – A type of cloth that eliminates visible dirt and other bigger particles from the water.
• A polisher – Removes residual chemicals, such as chlorine and undissolved chemicals, from the water.
• Activated carbon filters – Removes dirt, parasites, and pesticide impurities.

Any typical best gravity based water purifier usually comes with two types of carbon filters; pre-activated and post-activated. These both are collectively responsible for filtering the volatile organic compounds from the water, resulting in improving its taste, color, and odor.

Some gravity-based filters also feature ultrafiltration technology. This is simply a membrane, called UF membrane, having pores of size 0.1 micron. This allows filtering out microbes like bacteria and cysts. Opting for a gravity-based filter with a UF membrane is highly recommended.

When to use

You should use a gravity-based water purifier when:

• The TDS (totally dissolved solids) content of water is less than 300 ppm, and
• The water doesn’t contain too much mud, and
• The biological impurities are absent.

A best gravity based water purifier in India is ideal to use in locations where water is filtered thoroughly by the municipality prior to individual household distribution.

As the water fed to the gravity-based water purifier, in the case of municipality intervention, is chemically treated and free from heavy metal impurities, like arsenic and lead, as it is running water, the only requirement is to improve its taste, odor, and color. It is easily made possible using a  gravity-based water purifier.

Conclusion

Gravity-based water purifiers are great when there isn’t many chemical or biological impurities present in water. Due to their non-inclusion of electricity, they are simpler and inexpensive water filtering units. So, what are you waiting for! Your best gravity-based water purifier awaits.
