Important things to know before getting gravity water filters

A gravity water filter is the easiest way to remove solid impurities or precipitation from water. The impurity is filtered out into the filter paper, making the water distilled and pure for drinking. Gravity filter collects any solid material that is insoluble. These filters don’t require any electricity or any connection to the water supply. The container gets fitted with a small tap and you access safe, filtered water. This purification method has outstanding benefits and abilities. Gravity water filters come in different shapes and sizes, but before using gravity water filters you need to know some important things about why to choose gravity water filters out of other, ordinary ones.

What is a gravity water filter?

A gravity water filter allows you to filter water filled with harmful contaminants with the help of gravity. For making it work you don’t need any electricity; it works on its own when the water is poured into it.

Does it meet your needs?

This totally depends on your consumption. Once you have understood just how much water you need, you can work out how much liquid you can filter from a filter cartridge. This way you can identify which filter meets your requirements.

Does the capacity matter?

Yes, it does as it is basically one of the main concerns of every person who wants to drink water that is clean and fresh. But do look for the ones that have a hook at a top so that while the water filters and you wanna use it, you can do so instantly by hanging it on a tree which will then allow you to use the filter comfortably. Some filters have the capacity to hold a gallon of water and that can be a little heavy to lift so that hook comes in handy as it gives you easy access to the water, without any inconvenience. 

What do you need to filter?

You need to get your water analyzed to know what chemical impurities you need to filter it for. This will make it easy for you to choose the right filter option for your water filtration. You can get your water report done with the EPA agency in your state. Or, if the agency is unreachable, you can conduct a water test by yourself with a water kit and check results.

Alkaline or acidic water?

Another thing you need to check is the pH level of your water. A neutral level is 7 on the pH scale and any number that is lower or higher than that means it is acidic or alkaline, respectively. Water that is high in alkalinity has some health benefits and if you want to get those benefits then go for a gravity water filter that improves pH levels.

Types Of Gravity Water Filters

Just like a water filtration system, gravity filters come in variations too. Each one has its own pros and cons. Let’s have a look at all those types:

 

Ceramic Gravity Water Filter: This filter type is best for those who are allergic and are sensitive to chemicals. It works just like a steel water filter unit; you just have to put water inside the top ceramic chamber and you can have the system running.

 

Stainless Steel Gravity Water Filters: Stainless steel filters are available in the market today in huge sizes and are comparatively bigger than the average ceramic unit. The stainless steel units are ideal for home use. They are more durable as compared to the ceramic ones. They are lighter in weight and less complex to install.

 

Gravity Bag Water Filter: Also known as a backpacking filter, this is an on-the-go filter unit. This is best for people who travel a lot or go camping or hiking.

Normal water filters vs gravity water filters

Drinking-water filters come in different varieties, like countertop, pitcher or under-sink option. Many of these use a combination of activated carbon/catalytic carbon to distill the water from impurities that are harmful to your health, more likely chlorine, chloramines, heavy metals, chlorine-resistant cysts like giardia and cryptosporidium, pharmaceuticals and more.

 

Purification is the best process. Water purifiers come in many shapes and sizes. They not only filter out impurities but remove some minerals from the water as well. This process is done by two methods, namely reverse osmosis and distillation. Distillation works much like reverse osmosis but not only does it purify water from contaminants, it also distills the unnecessary minerals and removes bacteria. Through the double screening process, it screens out almost all unnecessary particles, be they small or big.

How does a gravity water filter work?

It works by using the force of gravity to push the water down while it filters. Filtering almost every last bit of the harmful contaminants to provide you with clean and better water. Moreover, this type of filter method is workable for distilled water, etc.

Can you use this gravity water filter while you go backpacking?

Yes, certainly, you can use this gravity water filter when you go backpacking as it proves to be a great companion when you are in need of clean and fresh water to drink and you have run out of supplies. It is pretty easy to use and can be stored in your backpack without taking much space as it is portable and lightweight.

Conclusion

And so, my discussion of gravity water filters for multiple purposes comes to a close. Out of all my picks, you can choose whichever goes best with your particular requirements and you’ll be good to go.
