Why Choose a Gravity Water Filter?
A gravity water filter gives you more filtered water than a typical pitcher without the plumbing or electricity required by many larger filter systems. For many households, that makes it a practical middle ground between a pitcher and an under-sink filter.
No Plumbing, No Installation, No Electricity
Gravity water filters are simple by design. You fill the upper chamber with tap water, and gravity pulls the water through the filter elements and filtration media into the lower chamber. No electricity or plumbing is required.
That makes a gravity system useful for renters, cabins, RVs, off-grid homes, or anyone who does not want to modify a kitchen sink. It is also portable if you move and can continue filtering during a power outage.

The slower gravity-fed process gives the water more contact time with the filtration media, which helps the media reduce contaminants before the filtered water reaches the reservoir.
More Capacity Without Constant Refilling
A pitcher water filter is compact and easy to keep in the refrigerator, but its smaller capacity means you refill it more often. Pure Water Freedom’s Smart Fluoride Pitcher, for example, holds about 8 to 12 cups. The ARMOUR stainless steel gravity filter holds 2.25 gallons of filtered water.
Filter life varies by model, water quality, usage, and the number of cartridges in a system. With two Coldstream FTO Plus replacement filters, the ARMOUR is rated for up to 800 gallons or about 12 months before replacement is recommended.
For households that use a substantial amount of drinking water, that larger reservoir can also reduce reliance on bottled water.

Do Gravity Water Filters Remove Fluoride?
Some do, but fluoride reduction is not a standard feature of every gravity filter.

Standard activated carbon alone does not address fluoride, so buyers looking for fluoride filters need to check the filtration media and independent test data for the specific filter elements they are considering.
The Coldstream FTO Plus used in the ARMOUR system combines a ceramic outer shell with a granular activated-carbon core. It is independently tested and certified to NSF/ANSI 42, 53, and P231 standards. Test data reports 97.5% fluoride reduction, along with reduction of chlorine, lead, and other heavy metals, bacteria, microplastics, and other contaminants.
The ARMOUR Stainless Steel Gravity Filter System
The ARMOUR Stainless Steel Gravity Filter System is a countertop gravity water filter made with 304 stainless steel. Its housing, spigot, and included stand are stainless steel, and the system uses two Coldstream FTO Plus ceramic gravity water filter cartridges.
It holds 2.25 gallons of filtered water and has a flow rate of up to four liters per hour. The two included filters are rated for up to 800 gallons or about 12 months of use.
Independent testing covers more than 150 contaminants, including fluoride, lead, bacteria, viruses, and microplastics.
Is a Gravity Filter Right for You?
A gravity filter is a practical choice if you want more clean drinking water on hand without plumbing or electricity. If you prefer filtered water directly from the kitchen sink, do not want to refill a countertop tank, or need a higher daily flow rate, an undersink filter system may be a better fit.
