Water Filter Replacement

Your water filter keeps your house’s water clean and healthy.

A water filter will help purify your home’s water. Over time, the water filter will need to be replaced. Find out what kind of filter is right for you, and when you need to replace it.

Signs You Need to Change Your Water Filter

Water Filter Replacement
We’re here to help you figure out which filter will work best for you, and when you’ll need to replace your water filter cartridge.

There are a few ways you can tell it’s time to change your water filter. If your water has an odor or unpleasant taste, it’s most likely time to change your water filter. A decrease in water pressure can also be a sign.

Replacing Water Filter Cartridges

There are two ways you can figure out when to change your water filter cartridge. Filter life is determined by how many gallons are being filtered on a daily, weekly and monthly basis. However, this is based on average water use.

Water usage can greatly vary between households. It also depends on what kind of water is being filtered. If you have a lot of sediment going through your water, you’ll have to change your water filter more frequently. If you have relatively clean water to begin with, you’ll have to change your filter less.

We provide general guidelines on when to replace your filters, based on the type you have in your home. Keep in mind your water usage and water quality when replacing water filters. You can always consult the manufacturer’s instructions on when to replace your filters.

Types of Water Filters

Water Filter Pitcher

Water filter pitchers can reduce lead, chlorine and mercury in your drinking water. The pitcher can be stored in the refrigerator. Change the pitcher’s filter about every two months or 40 gallons.

Faucet Water Filter

These water filters are mounted on your faucet. The filter can be turned on and off. Many faucet water filters reduce byproducts from lead, mercury and chlorine. The typical filter life for faucet mounted filters is two to three months, or 100 gallons.Your filter will last longer if you switch it off when you’re not going to be drinking or cooking with the water you pour.

Under Sink Water Filter

Under sink filters come in a variety of models. You can buy under sink water filters with multiple cartridges. Each cartridge filters a different contaminant. These filters are used on individual faucets, and are hidden under the sink. These are ideal for drinking water. Under sink filters last between six and 12 months.

Countertop Water Filter

These filters sit on top of your counter. They’re connected to the faucet. A valve lets you turn the filter on and off. You have to pour water through some countertop water filters. The cartridge will need to be replaced every six to 12 months.

Whole House Water Filter

You will need a whole house water filter if you have to filter a lot of sediment. They’re installed in your home’s main water line, and filter all the water going into your home. Whole house filters provide safe drinking, bathing and washing water for your house. They can act as a pre-filter for other filters in your home. Whole house water filters should be changed every three months or 15,000 gallons.

Types of Water Filter Systems

The two most common water filter systems you’ll find are carbon water filters and reverse-osmosis water filters.

Carbon Water Filter

Carbon is a porous material that removes sediments and silt from your water. The carbon absorbs these materials so they don’t end up in your house’s water. You’ll find carbon in pitcher filters, faucet-mounted filters, under sink filters and whole house filters. Carbon filters remove pesticides, herbicides, lead, PCBs, some bacteria and more from your water.

There are granulated activated carbon (GAC) filters and carbon block filters. Carbon block filters have more surface area, making them more effective than their GAC counterparts.

Reverse-Osmosis Water Filter

Pressure pushes water through a semipermeable membrane in a reverse-osmosis filter. The membrane traps the sediments and silt from going through to your faucet. These filters are used to catch substances that a carbon filter can miss, including sulfates and chlorides. Reverse-osmosis filters use much more water than they produce. They’re best for cooking and drinking water.
