It can be easy to get confused with the variety of water filtration systems on the market.
Ceramic filters and sediment filters are two more popular choices for domestic use.
This article will give you all the details you need to know regarding their respective properties and help you decide the one most suited for your needs.
Ceramic water filters are one type of sediment filter. They use millions of tiny pores on the ceramic surface to stop floating particles, even bacteria, from contaminating your water supply.
They can be installed in the household at a specific point of use or used via a portable filtration device.
Ceramic filters can also be used in conjunction with other compounds to help them target specific contaminants. Here, the ceramic only makes up the outer shell of the filter element. The inside can be filled with various filter media:
Silver ions make them bacteriostatic – preventing bacteria, mold, and algae from growing on the filter.
Activated carbon is a carbon treated to become highly porous, which enables it to adsorb chemical compounds (such as chlorine and herbicides) from the water supply.
There are two types of carbon that can be used:
Ion exchange filter media is great for removing heavy metals and other dissolved ions.
Sediment filters act as a physical barrier, preventing contaminants from reaching your taps. As the name suggests, these filters eliminate floating sediment/particles – such as sand and debris.
Sediment filters are made from various materials: Wound string or cord, polypropylene, polyester, cellulose, cotton, and, indeed, ceramic!
Surface and depth filters are the two most common sediment filters.
Surface filters use a thin sheet to trap particles on the surface. Their accordion-shape is why they are often called ‘pleated filters’. This structure gives them a larger surface area than depth filter, and they also benefit from being washable (and, therefore, reusable).
Depth filters pass the water through a thick wall of filter media, treating it as it passes through its depth. They often have graded density, whereby larger pores on the outside trap bigger particles, and the tighter pores inside trap the smaller particles.
Ceramic filters are one type of sediment depth filter.
In the end, the best filter for you will be the one suited to the quality of the water supply and your particular needs.
