Having crisp, clean, cold water pouring over easily dispensed ice is convenient. It’s vital to understand how to maintain your fridge water filtration to ensure your water remains safe. Learn how often to change refrigerator water filter. Plus, learn the basics of water filtration and how to reduce the stress of maintaining clean on-demand water.

What Kind of Filtration Does a Refrigerator Have?

Most fridges use a two-stage filtration cartridge. They are designed to filter what city water treatment might leave behind. These cartridges are usually easy to access for removal and simple to install when it’s time to swap them out. These cartridges use a simple filtration system that combines sediment and activated carbon filters.

  1. The sediment filter blocks larger particles from passing through it.
  2. An activated charcoal filter attracts chlorine (and some other chemicals) and converts it into salt which is then trapped within the filter.
  3. Clean water passes into your cup.

 What Does a Fridge Filter Remove?

Refrigerator filters do not remove all contaminants. They focus on the most significant risks city water treatment can leave behind. Generally, fridge filters have a micron rating of only 20, so they can miss smaller particle contaminants that can pass into your water and cannot filter viruses and bacteria. They typically remove or reduce the following:

  • Lead
  • Chlorine
  • VOCs
  • Chloramine

So What’s a Good Micron Rating For a Filter?

The Micron rating tells you how small a particle needs to pass through the filter. The smaller the rating, the smaller the holes in the filter. A fridge filter typically has a micron rating of 20, which means it will still allow particles visible to the naked eye to pass through. You’ll want a filter rated 5 or lower to filter particles visible to the human eye. To remove bacteria and viruses, you’ll want one or smaller.

What’s the Risk from Unfiltered Contaminants?

If your filter stops working, what might the water contain? The contaminants no longer being filtered can wind up in your drinking water and potentially lead to various issues.

Lead

Frequently used in a range of products before 1986, lead is not uncommonly found in older pipes. The EPA recommends completely removing lead from water, as it’s highly toxic and can lead to many health issues, many of which are severe.

Chlorine

A great disinfectant that effectively removes waterborne disease, chlorine may be used to treat city water. If not properly filtered out, it leaves an awful taste behind.

VOCs

According to the EPA, about 20% of city water supplies contain VOCs. These chemicals come from many sources and can lead to a range of health issues, including liver and kidney damage, nausea, irritation of the eyes and throat, and headaches. They also contribute to foul odors and tastes in your water.

Chloramine

A product of some city water filtration processes, chloramine combines chlorine and ammonia. There are ongoing concerns about the safety of chloramines in our water.

How Long Does a Fridge Filter Last?

So how often to change refrigerator water filter to avoid it to ensure it continues to work well? You need to change out your refrigerator filter every six months. Sometimes, you might be able to wait as much as one year. However, if you wait too long, your filter will stop working and may put your family at risk. Can include:

  • Harbor bacteria grow in the charcoal medium, which may pass into your water, potentially causing illness.
  • Release contaminants into your water present in the water or previously stored in the filter.
  • Clog the line – no more water emerges.

If you use a filter past its replacement date, your water may be contaminated with bacteria, viruses, chemicals, or other risks depending on the source of your water and what’s happening inside your depleted filter. Knowing how often to change refrigerator water filter and follow through on it is essential.

Helpful Tips to Help You Remember to Replace Fridge Filters

If you are relying on your fridge filter, it’s a good idea to set a reliable schedule to replace it before it’s clogged. These tips help you prepare to keep your fridge’s filter working as intended.

  • Mark it on a calendar – digital or otherwise – a month before the filter must be replaced.
  • Pair filter replacement with other routine bi-annual household tasks. Pairing this task with the one you are already used to doing twice a year will help you remember.
  • Buy filters in bulk. When you get low, buy more. Having multiple filters on hand means that when it’s time to replace the old ones, there won’t be time for bacteria to develop.
  • Set up an automatic water filter delivery. Some companies will allow you to set up an automatic shipping schedule for fridge filters. Not only does this keep you in the supply of fresh filters, but the new arrival will also remind you that it’s time to swap.
  • Consider whole-house water filtration. You can ditch the fridge filters, remove more contaminants, and reduce upkeep with one of these.
