Water is essential for life, and it’s important to make sure that the water you’re drinking is clean and safe. One way to do this is to change your water filter regularly. A dirty filter can allow contaminants to build up in your water, which can lead to a variety of health problems. Changing your water filter is a simple process that only takes a few minutes, and it can make a big difference in the quality of your water.
The first step is to identify the type of water filter you have. There are two main types of water filters: pitchers and dispensers. Pitcher filters are typically used to filter small amounts of water, while dispensers are used to filter larger amounts of water. Once you know the type of filter you have, you can follow the steps below to change it.
If you have a pitcher filter, the first step is to remove the old filter. To do this, simply lift the filter out of the pitcher. Next, rinse the pitcher thoroughly with clean water. Then, insert the new filter into the pitcher and fill it with water. Finally, let the water filter for about five minutes before drinking it. If you have a dispenser filter, the process is similar. First, remove the old filter by turning the knob on the top of the dispenser. Next, rinse the dispenser thoroughly with clean water. Then, insert the new filter into the dispenser and turn the knob to lock it in place. Finally, let the water filter for about five minutes before drinking it.
Determining the Type of Water Filter
Identifying the type of water filter installed in your home is crucial before attempting to replace it. There are several types of water filters, each designed for specific water contaminants and flow rates. Understanding the type you have will ensure you purchase the correct replacement and achieve optimal water filtration.
1. Sediment Filters
Sediment filters are the most basic type of water filters. They are designed to remove larger particles, such as sand, dirt, and rust, from water. Sediment filters are typically installed at the point of entry (POE) of the water supply, which is usually located in the basement or crawl space. They can also be installed under sinks or on individual faucets.
Sediment filters come in two main types:
| Type | Description |
|---|---|
| Spun-bonded | Made of polypropylene fibers that are fused together to create a porous barrier that traps particles. |
| Wound | Made of a string of yarn that is wound around a central core to create a dense, pleated filter that catches particles. |
Sediment filters should be replaced every 3-6 months or more frequently if the water is heavily contaminated.
Locating the Filter Housing
Finding the filter housing is the first step in changing a water filter. It is usually located in one of two places:
Under the kitchen sink
This is the most common location for a water filter housing. To find it, look for a white or clear cylindrical canister with two water lines connected to it. The canister will likely be mounted to the wall or under the sink cabinet.
Inside the refrigerator
Some refrigerators have built-in water filters. To find the filter housing, look for a small door or panel on the inside of the refrigerator door. The filter housing will be located behind the door or panel.
Once you have located the filter housing, you can proceed to the next step of changing the water filter.

| Inside the refrigerator | A small door or panel on the inside of the refrigerator door, with the filter housing located behind it. | [Image of a filter housing inside a refrigerator] |
Shutting Off the Water Supply
Before you begin changing the water filter, it’s essential to shut off the water supply to prevent any flooding or leaks. Here’s a step-by-step guide on how to do it:
-
Locate the water shut-off valve
The water shut-off valve is usually located near the water filter, under the sink. It’s typically a small, round handle or lever.
-
Turn off the cold water valve
Most water filters are connected to the cold water supply. Find the handle or lever for the cold water valve and turn it clockwise to shut off the water.
-
Turn off the hot water valve (if applicable)
If your water filter is connected to both cold and hot water, you’ll need to shut off the hot water valve as well. Find the handle or lever for the hot water valve and turn it clockwise to close it.
-
Confirm that the water is off
Turn on a cold water faucet to check if the water is shut off. If water is still flowing, double-check that the shut-off valve is fully closed.
| Valve Type | How to Turn Off |
|---|---|
| Lever valve | Turn the lever clockwise 90 degrees. |
| Gate valve | Turn the handle clockwise until it stops. |
| Ball valve | Turn the handle 90 degrees perpendicular to the pipe. |
| Needle valve | Turn the screw clockwise until it closes the valve. |
Releasing Water Pressure
Releasing the water pressure from your water filtration system is crucial before attempting to change the filter. Here’s a step-by-step guide on how to do it:
1. Locate the Main Water Shut-Off Valve
Find the main water shut-off valve for your home, typically located in the basement, utility closet, or near the water meter. It’s usually a large, round valve.
2. Turn Off the Water Supply
Use a wrench or pliers to turn the shut-off valve clockwise until it’s tightly closed. This will stop the flow of water into your water filtration system.
3. Open the Faucet
Open a faucet downstream from the water filtration system, such as a kitchen or bathroom sink faucet. This will allow the remaining water pressure in the system to escape.
4. Wait for Pressure to Release
Wait until the water flow from the faucet stops completely. This indicates that the water pressure has been released from the filtration system. If the water continues to flow, check if the shut-off valve is tightly closed and try again.
| Estimated Completion Time | Difficulty Level |
|---|---|
| 5-10 minutes | Easy |
