Water Filter Cartridge Types
Thought there was only one type of filter cartridge out there? Think again. There are now a whole host of filter cartridges available, with different designs and purposes.Get more news about Best Price Water Filter Water Filter Element Production Equipment,you can vist our website!
In this guide, we’ve shared everything you need to know about the most common water filter cartridge types. By the end, you’ll know which filter cartridges you need to tackle the problem contaminants in your water supply.
What Are Filter Cartridges?
It might sound like an obvious question, but just in case you need clarification: a water filter cartridge is a cylindrical canister that contains filter media.Water filter cartridges are most commonly found in multi-stage under-sink filters and whole house filtration systems. These cartridges sit inside filter housings in a filter system.
The media in a filter cartridge usually has a certain capacity, or lifespan. When the media becomes completely saturated with contaminants, the cartridge needs to be replaced in the filter housing.
Note: We’re purely talking about filter cartridges in this guide, not the other types of filtration media, processes, and technologies. Other websites are making false claims about “UV light filter cartridges” and other cartridges that simply don’t exist. They don’t know their stuff.
Sediment filters are popular water filter cartridges for whole home installation, or pre-filtration on a point of use system..A sediment filter traps large, solid particles, like dust, dirt, and rust, in water. This type of filtering cartridge is either installed as a standalone filter or as a pre-filter stage before a whole house water filtration system.Depth filters are typically made from melt-blown string, and gradually remove smaller and smaller impurities as water passes through the filter to the core. Surface filters have a large surface area with a pleated paper design and retain particles on the surface of the media. Depth filters are usually more expensive, and last longer, than surface filters.
Why isn’t a sediment filter typically used as a standalone filter cartridge? Because sediment filter media can only remove particles with relatively high micron ratings. Contaminants with low micron ratings, like chemical contaminants, heavy metals, and microbes, will simply slip through a surface filter or depth filter designed for sediment removal.
