Amid rising water pollution and demand for safe drinking water, water filtration tech has advanced—traditional and modern filters differ in principles, performance, and usability. Below is a streamlined comparison.
What Are Traditional Water Filters?
They use basic, decades-old methods:
Sand & Gravel Filters: Remove suspended solids via layered sand/gravel; used in large-scale treatment.
Activated Carbon Filters: Adsorb organics, chlorine, odors, and some heavy metals; common in household dispensers.
Ceramic Filters: Trap bacteria/solids with micron pores; reusable after washing for home use.
Advances in Modern Water Filters
They integrate advanced tech for higher efficiency:
Reverse Osmosis (RO): Uses 0.0001-micron semi-permeable membranes to remove dissolved solids, heavy metals, bacteria, and viruses; delivers high-purity water.
Ultrafiltration (UF): 0.01-0.1-micron membranes remove bacteria, viruses, colloids, and solids; used in home and industrial purification.
UV Sterilization: Destroys bacteria/viruses with short-wave UV; eco-friendly, often paired with other filters.
Nanofiltration (NF): Pores between UF and RO; removes organics, some inorganics, and hardness ions for targeted needs.
