Gravity Water Filter Buying Guide

gravity water purifier

What are Gravity Water Filters and How Do They Work? 

A gravity water filter is an efficient device that filters and purifies contaminated water with the help of gravity. Gravity water filters are highly convenient because they do not require any plumbing or electricity to operate. 

Plus, they are suitable for home use and come in handy during outdoor adventures and sporting events

Gravity water filters consist of an upper and lower chamber. Once you pour contaminated water into the upper chamber, the filter elements remove harmful bacteria and other pollutants. Using the force of gravity, the water goes through to the lower chamber. 

Once this process is complete, you can pour yourself a glass of clean drinking water. 

Types of Gravity Water Filters

There are different types of gravity water filters that you can choose from depending on your budget and filtered water requirements. These include:

Countertop

Countertop gravity water filters are the most common type available in the market. They come in different shapes, sizes and materials. 

If you opt for a high-grade stainless steel countertop filter, you can easily place it on your kitchen countertop, office coffee table, or patio furniture without compromising on space. 

Countertop filters are also usually lightweight, making it easy to transport them from one area to another if needed. 

Hanging

Hanging gravity water filters are extremely popular among people engaging in regular outdoor sports and other activities. They are mostly lightweight and compact, making them easy to store in your backpack or luggage. 

Hanging gravity water filters are as efficient at purifying contaminated water as any other type of gravity water filter. Plus, they include an integrated carry loop and a bail handle for you to hang them from an elevated source wherever you are. 

Ceramic

Ceramic gravity water filters are known to remove harmful bacteria and protozoa from tap water adequately. They are especially recommended for people who are sensitive to chemicals and suffer from allergies as they use fewer chemicals than some other filters. 

Sediment

Sediment gravity water filters are designed to eliminate suspended solids, also referred to as sediments or turbidity. They function pretty much like a net that traps dust particles or harmful pollutants to deliver a flow of clean water. 

Why Buy a Gravity Water Filter Vs. Other Options?

gravity water system

Gravity water filters are better than most regular water filters because they use gravity to filter contaminated water. The water flows naturally from top to bottom, and the end result is clean and fresh water. 

Other water filters use potent chemical filters made out of granular activated carbon or other materials that remove impurities like chlorine and pesticide but can prove harmful over time. They also require electricity to operate, unlike gravity water filters. 

Plus, gravity water filters are available in various sizes, are primarily portable, and do not take much space as opposed to some other options. 

You also have the option of physically filtering your water by straining it through a sieve or a very fine cloth. However, this process proves to be quite tedious and does not guarantee the elimination of contaminants from your water. 

Overall, gravity water filters are safer and more efficient than other options owing to their portable nature and natural gravity filtration process. 

Key Features To Look For

You need to consider a few things before investing in a gravity water filter for your home or outdoor use. These include:

Portability

Portability isn’t the most crucial factor if you want a gravity water filter for everyday use in the kitchen. However, if you want a gravity water filter to take along on road trips or to quench your thirst while playing outdoor sports, you must invest in a lightweight and compact device. 

You can find highly efficient and portable gravity water filters that are durable and deliver freshly purified water on the go.

Flow Rate

A gravity water filter’s flow rate is measured in gallons per minute or GPM. You should invest in a gravity water filter with a higher flow rate if you require abundant drinking water throughout the day. 

Remember that a gravity water filter’s flow rate can decrease over time if the filter is dirty or has not been replaced when needed. 

Filter Capacity

A gravity water filter’s filter capacity is essential because it determines your water’s flow rate. 

A device that can accommodate up to 4 filters is best for large families or big gatherings because it increases the water flow rate. 

Anything less than that is suitable for small families and short outdoor trips. 

Filter Life and Replacement Frequency

Most gravity water filters have a lifespan of 6 to 12 months. The filters of most countertop devices are crucial when it comes to efficient performance and durability. 

Activated carbon filters and ceramic pre-filters are extremely popular due to their extended lifespan of 12 months. You can also find fluoride filters and 5-stage filters that last between 4 and 6 months. 

On the other hand, hanging gravity filters have a shorter lifespan of roughly 1 to 2 months, depending on the frequency of usage. 

The filter cartridge’s life expectancy is also essential and can be calculated by how much water it can filter over time. When exactly you need to replace the filter cartridge also depends on the water turbidity, which reduces cartridge life after each use. 

Materials Used

Gravity water filters are constructed of varying materials, including stainless steel, plastic, and synthetic fibers. 

High-grade 304 stainless steel filters are considered the most durable but may develop rust after extended use. Gravity water filters made of plastic are lightweight and easy to clean but are also prone to wear and tear.

Synthetic gravity water filters are flexible and suitable for outdoor use but may tear or present leakage over time. 

All these materials have their pros and cons, so choose wisely when making your final decision.  

Pros and Cons of Gravity Water Filters

Gravity water filters are now increasingly popular due to their efficient water purification qualities. While they have numerous advantages, there are also a few drawbacks to buying one. 

Pros

  • Low maintenance
  • Filter water efficiently
  • Available in various sizes
  • Mostly portable 
  • Do not take up much space
  • Suitable for indoor and outdoor use
  • Do not require electricity to operate
  • Remove bacteria and chlorine from tap water

Cons

  • Expensive 
  • Require filter replacements
  • May produce bitter-tasting water
  • Might result in rust and corrosion over time
  • May take longer to filter water than other water filters

Cleaning and Maintenance

gravity water filtration system

Cleaning your gravity water filter ensures a good flow rate of purified water and results in extended life.

You should clean the housing of your countertop gravity filter periodically. We recommend that you wash your hands before and after doing so or wear rubber gloves. 

Start by removing the filters, rinsing the upper chamber, the lower chamber, and the lid with the help of warm soapy water. 

Make sure that the housing and all its parts are dry before re-assembling. You can also mix bleach or other chemical additives with water to clean your gravity water filter to reduce potential mold and bacteria growth. 

Cleaning your gravity water filter’s filters is also vital to restoring the water flow after extended use. 

Remove the filter elements from the upper chamber by unscrewing the wing nuts and holding them under running water. Using a soft bristle brush, gently clean the filter lengthwise. 

Once clean, simply replace the filter elements, fill the upper chamber, and put the lid back on. Remember not to use any soap, detergent, or harsh solvents on your filter elements to avoid damage. 

The cleaning and maintenance for hanging water filters may be slightly different. You can simply clean your filter by using the backflushing method by collecting filtered water in a clean water bottle or reservoir. 

Attach the bottle or reservoir to the end of the nozzle and remove the connection of the unfiltered water to let the water flow in the opposite direction right above the filter cartridge. End this process by allowing clean water to flow back into your filter, after which you can use it right away. 

Installing a Gravity Water Filter

Installing a gravity water filter takes little time and effort because it does not require any plumbing or electricity to operate. 

All you need to do is put together all the components mentioned in its instruction manual to form the filtration system. 

However, some filters require priming before use. To do so, simply run them through water for a few minutes before setting up the system.
