What Is a Standard Size of Water Filters?

Your refrigerator water is starting to taste funny and no longer crystal clear, so you know it’s time for a new filter.

But with so many different options, you’re worried you’ll buy the wrong size.  Let’s help simplify it for you.

There are different models and water filter cartridge sizes available, such as the 20-inch water filter, so it’s important you make the right choice that fits perfectly and works optimally.

If you are shopping for a replacement piece, there are a few things you should know to help you choose one that fits your needs. For example, you should know:

• What size does your system use – standard or proprietary?
• What is the size of your refrigerator cartridge housing?
• What water problems exactly do you want to fix?
• Is there a specific micron rating you need for your filter?

To choose the best replacement unit, you must first know what kind of filter you have and what you want to achieve. Using this information, you can determine which is right for your situation.

Here’s an overview of standard-sized fridge filters, in addition, other to other possible size options of water filters

The standard size of water filter

Generally, standard-size filters refer to pieces that have standard dimensions. Standard filter housing come in five different categories:

• 5″ x 2.5″
• 10″ x 2.5″
• 20″ x 2.5″
• 10″ x 4.5″
• 20″ x 4.5″

Several manufacturers make these standard water filter sizes. Your filter housing should take any cartridge from the right size category.

In most cases, you can determine the water filter standard size you need by looking at the owner’s manual. If you can’t find the instructions,  simply measure the inside diameter of your current unit with a ruler or tape to determine which size will best suit your needs,

Note that while a size category is specific, there may be some variance in exact dimensions.  For example, cartridges that fall into the 10″ x 2.5″ standard category sometimes measure 9.75″ x 2.75″, and in other cases, they may measure 10.25″ x 2.875″.

In other words, regardless of what standard of size water filter is, the exact dimensions are subject to some variation. Therefore, some cartridges have slightly different dimensions, even if they are the same.

But this is nothing to worry about! It’s in fact one of the many advantages of standard-sized systems as they are built to accommodate these minor variations.

Size options of water filters  you can choose from

To choose the right replacement cartridge for your cartridge, you’ll need to know what size you need. They come in many different types, and you can usually change to a different type if necessary. You can replace a carbon unit, for example, with a sediment one.

Fridge cartridges can be classified into the following types:

• Bone char
• Calcite
• Activated carbon
• Sediment

Each type of these cartridge treats a different problem with water. If you’re having trouble deciding which type to use, get in touch with one of our certified water specialists at Filterway.

Micron Ratings

You will likely need a cartridge with a specific micron rating if you wish to physically remove contaminants from your liquid. A micron is a unit of size and equals one micrometer. One way to understand how small microns are is to compare them to human hairs, which measure about 90 microns in width.

Micron ratings are typically assigned to replacement cartridges like sediment filters. A rating can range from 50 microns down to 0.35 or lower.

Low ratings mean that the cartridge will remove more pollutants, but they also mean that water will pass through the system more slowly, thus requiring more frequent replacement.

Conclusion

When it comes to water cartridges, you have a lot of choices. There are many varieties, including those that combine the sediment and carbon cartridge into a single piece. Essentially, there is no one-size-fits-all fit for water cartridges for your refrigerator.

We hope that this article has proved to be helpful, and has cleared up some of the confusion with finding the right size water cartridge you need.
