Gravity Water Filter: Pros and Cons

If you are looking for a gravity water filter system, this article is for you.

We will look at common home filtration types, then the pros and cons of gravity-fed systems.

Our family prefers the Berkey system, but you can decide for yourself.

What Are Different Types of Water Filtration Systems?

Here are common options besides gravity filters:

• Distillation – Water is heated and the steam is collected when it condenses.
• Reverse Osmosis – Water is pushed through a fine membrane.
• Ultraviolet – A separate technology that uses UV light. It does not work the same way as a carbon gravity filter.
• Ceramic Filters – Water passes through ceramic media.
• Other chemical-treatment media – Some systems target specific dissolved contaminants rather than using gravity carbon elements.

What Is a Gravity Water Filter?

A gravity-fed system like Berkey is simple. Water sits in an upper chamber and drips through filter elements into a lower chamber.

The elements use small pores and adsorption media to reduce many contaminants as the water passes through.

No pump and no electricity are required. Some under-sink systems instead use household water pressure.

Are Gravity Fed Systems Efficient?

A good gravity system is efficient for daily tap water and for use during a power outage.

The system we recommend is Berkey. Independent laboratory tests show strong reduction of many chemical contaminants. In some tests, levels were below what the lab could detect.

That performance, plus no power requirement, is why gravity systems work well in a home emergency kit. They also assemble without special tools.

Types of Gravity or Drip Fed Water Filtration Systems

Gravity filtration has been used for a long time in large-scale water treatment. Household countertop systems are a smaller version of the same idea: water moves down through media by gravity.

See the EPA’s basic information about drinking water for how public supplies are treated.

Public Works Systems

Municipal plants use a series of treatment stages. That is a different process from a home Berkey. A home gravity filter is an extra step after city treatment.

In-House Gravity Water Filtration

Most homes only need a countertop system. You pour municipally treated tap water into the top chamber. Gravity moves it through the filters into the lower chamber. You dispense it from the spigot.

Things to Consider When Buying a Gravity Fed Water Filtration System

Water Quality and Capabilities

Match the filter to municipally treated tap water and the contaminants you care about, such as chlorine, PFAS, and heavy metals.

Berkey systems are intended for that tap-water use, not for untreated surface water.

Capacity

Choose a size based on how much drinking and cooking water your household uses.

Speed of Filtration

Flow rate depends on the model and the number of elements. Bigger systems and extra elements filter faster.

In Conclusion

Gravity-fed systems are simple and reliable for filtered tap water, including during power outages.

Berkey gravity filters have been independently tested and are used to reduce 200+ common tap-water contaminants. No electricity. No plumbing. Official replacements are the Phoenix filters.
