Tips to buy best Gravity Water Purifier

To make sure you don’t regret your decision of purchasing the wrong water purifier you must follow the below-mentioned gravity water purifier buying tips :

Filters used in gravity water purifiers?

The gravity-based water purifiers do not use electricity for the purification process. The water purifiers use activated carbon filters. These filters work on the principle of gravity and do not require any external force. Activated carbon filters are made up of small carbon granules that absorb the impurities. Almost every gravity water purifier uses activated carbon filters. Some of the renowned water purifier brands also provide UF-based gravity water purifiers. The Ultrafiltration technology is the most advanced water purification process in gravity water purifiers as the pore size of these filters is very small. These filters can easily remove harmful microorganisms and cysts from the water.

Chemical Free Purification

Many water purifiers use chemicals in the purification of water that can be harmful to your health. You need to look for a water purifier that uses a chemical-free purification process. Chemical-free purification in gravity water purifiers ensures that the water is safe and healthy to drink. UF water purifier usually uses chemical-free purification methods to purify the drinking water. Reverse Osmosis water purification is not chemical-free.

Storage Capacity

While buying any water purifier, it is advisable to opt for high storage capacity. The high storage capacity ensures the availability of pure drinking water for a long time. Since the purification process, the flow of water is slow as it works on the principle of gravity. No external force is applied, therefore the gravity water purifier comes with a dual storage tank for raw water and pure water. You need to opt for a water purifier that comes with high storage capacity. You can easily buy a water purifier with a storage capacity of 20-24 liters.

Easy to Clean

Gravity water purifier requires cleaning after every 10-15 days. As a result, you need to opt for a water purifier that is easy to use and clean. The maintenance should be easy as you need to open the water purifier many times for cleaning.

Gravity water purifiers are the best choice if your water is already treated and free from heavy metals and dissolved salts. The price of a gravity water purifier is very economical. You can buy a decent gravity water purifier from the price range between 1500-4000. Also, the material of the body should be durable.

Buy Water Purifier

When it comes to gravity water purifiers, these are an excellent option for people looking for a simple, efficient, and low-maintenance way to purify drinking water. Unlike electric water purifiers, gravity-based systems don’t require electricity, making them an ideal choice for areas with inconsistent power supply or during power outages.

Here’s a complete buying guide to help you choose the best gravity water purifier based on your needs:

What is a Gravity Water Purifier?

A gravity water purifier is a non-electric filtration system that uses the force of gravity to move water through multiple layers of filters to remove impurities. These purifiers usually consist of a filter chamber (for filtration), a water storage tank, and a faucet for dispensing purified water.

Types of Gravity Water Purifiers:

1. Ceramic Water Purifiers:

   • Use ceramic filters that physically block harmful bacteria, dirt, and other impurities.

   • Ideal for areas where water is highly contaminated with suspended solids.

   • Often used for water from rivers or lakes.

2. Activated Carbon-Based Purifiers:

   • Use activated carbon to adsorb harmful chemicals, chlorine, and bad odors from the water.

   • Great for improving taste and odor in water.

3. UV-Based Gravity Purifiers:

   • Incorporate a UV filter that uses ultraviolet rays to kill bacteria and viruses in the water.

   • Best suited for areas with biological contamination.

4. Multi-Stage Gravity Purifiers:

   • Combine ceramic, activated carbon, and sometimes UV in multiple filtration stages.

   • Provide comprehensive filtration and purification for both chemical and biological impurities.

Factors to Consider When Buying a Gravity Water Purifier:

1. Water Source:

   • Quality of water: If your water contains high amounts of dissolved solids (TDS), you’ll need a multi-stage gravity purifier. If the water is mostly contaminated with bacteria or viruses, a UV-based or ceramic purifier would be better.

   • Source of water: Check if your water is from a borewell, river, or municipal supply. The purification needs may vary based on the contamination level.

2. Filtration Stages:

   • The more stages of filtration, the better the purification.

   • Single-stage filters generally remove larger particles like dirt and dust.

   • Multi-stage filters remove chemicals, heavy metals, chlorine, and can even eliminate bacteria and viruses.

3. Capacity and Storage:

   • Consider how much purified water you need daily.

   • Gravity water purifiers are typically available in 2L, 4L, 6L, and even larger capacities.

   • Larger capacity purifiers are great for bigger families or high water consumption.

4. Material and Build Quality:

   • Choose purifiers made of food-grade plastic or stainless steel for durability and to avoid harmful chemicals leaching into the water.

   • Stainless steel models tend to be more robust and longer-lasting but can be more expensive.

   • Plastic models are lightweight and more affordable but may degrade faster.

5. Maintenance and Replacement Filters:

   • Consider the ease of filter replacement. Some filters need to be replaced every 6 months to 1 year.

   • Ceramic filters can be cleaned and reused, while activated carbon filters need periodic replacement.

   • Make sure the replacement filters are readily available and not too expensive.

6. Purification Speed:

   • Gravity-based purifiers work slowly as water passes through various filtration stages. The purification speed depends on the size of the filter pores and the number of stages.

   • If you need purified water quickly, consider models that have faster filtration without compromising on the purification quality.

7. Certification and Standards:

   • Look for certifications from organizations like the BIS (Bureau of Indian Standards) or FDA.

   • Certification ensures that the purifier has been tested and meets safety and health standards.
