Do Water Filters Remove Bacteria?

Remember when we were kids? After playing on a hot summer day, all we wanted to do was go inside and drink water from the tap.

We didn’t think about what was in it. We only wanted to quench our thirst. But as we got older, there was more concern about what was in the tap water we grew to love.

Bacteria in water can be a serious problem. Many people rely on water to supply their cooking, cleaning, and drinking needs, so it’s important to make sure it’s filtered properly. Let’s look at how water filters and other water treatments remove bacteria in water.

What Is Water Filtration?

Water filtration is when you remove bacteria and other contaminants from a specific water source. Water filters are essential for home living because unfiltered water can be damaging to our health. 

When purchasing a home, it’s essential to look at where you’ll be getting your water. Your water can come from a city source or a private well. Depending on the source, you’ll need to know what kind of filter to get for your home. You can always check your tap water quality at

Do Water Filters Remove Bacteria In Water?

Yes, water filters do remove harmful bacteria and diseases that could be in your water supply. But, they may not remove all of the contaminants in your water supply.

That’s why it’s crucial to have your water tested and filtered. For a community water supply, the water you use goes through four steps to make it drinkable.

1. Coagulation and Flocculation

During coagulation, specific chemicals, like aluminum sulfate, are introduced to the water to counterattack the possible dirt and bacteria that may be in it. Because of this, micro flocs form, showing the combination of the chemicals and the suspected bacteria.

After coagulation, flocculation begins. Flocculation mixes the micro flocs to show other particles that may be hiding. This mixing creates larger flocs which help prepare the water for the next stage.

2. Sedimentation

The next step in the filtration process called sedimentation happens after all of the flocs settle at the bottom of the container. The longer the water goes uninterrupted, the more clumps will form at the bottom of the container. 

3. Filtration

Some particles like parasites, viruses, and dust may still be floating in clear water. Although the clumps of particles have formed and are at the bottom of the container, filtration is still necessary. 

During this process, water passes through physical materials like sand or charcoal to remove particles. Sand filtration is the most common method of eliminating bacteria in water. It’s been used for over 200 years and removes harmful bacteria that can cause stomach problems.

Advanced countries use rapid sand filtration to clean their water supply. It is an expensive method to use because of the manual maintenance that’s involved. But large quantities of water get filtered faster to meet the demand for their countries.

4. Disinfection

The last filtration stage is disinfection. Monochloramine is added to the water. But it isn’t the same chlorine that’s added to pools.

Monochloramine is safe and makes water drinkable. It also protects water as it travels to your home because it is exposed to germs in the pipes

What Kind of Filter Should I Get?

Well, that depends on your household needs. Think about how often you drink water from the tap or your refrigerator. The most popular types of water filters are whole-house water filters and under-sink water filters. But there are various types of filters that you can get for your home.

Whole House Water Filter

Whole-house water filters treat all of the water that’s entering your home, not just your drinking water. A water filtration system gets installed to your home’s primary water source.

It’s a great system to have because you’ll be able to relax knowing that all of the water in your home is treated. Although they are pricey, families benefit greatly.

Under-Sink Water Filter

Under-sink water filters are installed under your sink and send water through a specific tap to be filtered. The special fixture is installed next to your sink. This is an affordable filter and will last you a long time. 

Refrigerator Water Filter

Other sources in your house that produce water should also be filtered depending on the filter you already have. Make sure you have a refrigerator water filter if your fridge produces drinking water.

Refrigerator filters are great because they also filter the water that your fridge uses to make ice. The water passes through activated carbon to remove contaminants. 

Make sure to replace your fridge filter every six months, because it collects a lot of harmful particles. If you leave it too long, you may have to look for a costly water filter replacement because your fridge malfunctioned.

Water Pitcher Filters

Use water pitcher filters if you’re not sure about the contents of your water. This is a relatively cheaper option if you don’t want to install an entire system in your house or under your sink.

Just fill your pitcher and wait for the water to filter through the cartridge. But keep an eye on it because you’ll have to get replacement filters now and then to keep your water clean.

Reverse Osmosis System

The reverse osmosis system is also popular because it can remove almost all of the contaminants in your water supply. It removes some healthy minerals, but it can add them back to balance the PH levels of the water to make it drinkable.

Filtered Water Means A Safer Home

Having a water filter for your home is a no-brainer. It will remove bacteria from the water and you won’t have to worry about what you’re drinking. Your kids will also be safe, and that is what’s most important.
