Reverse Osmosis (RO) Water Purifier:

Process: RO purifiers use a semi-permeable membrane to remove impurities and contaminants from water. It works by applying pressure to the water, allowing only pure water molecules to pass through while blocking larger molecules and contaminants.

Features: Effective removal of heavy metals, dissolved salts, bacteria, viruses, and other impurities. Some RO systems also incorporate additional filters for comprehensive purification.

Ultraviolet (UV) Water Purifier:

Process: UV purifiers use ultraviolet light to disinfect water by deactivating bacteria, viruses, and other microorganisms. While UV doesn't remove physical impurities, it is highly effective in killing harmful pathogens.

Features: Chemical-free purification, no alteration of water taste or odor, and relatively low maintenance. UV purifiers are often used in conjunction with other filtration methods.

Activated Carbon Water Purifier:

Process: Activated carbon purifiers use a bed of activated carbon to adsorb impurities and contaminants. This porous material attracts and traps particles, chemicals, and organic compounds.

Features: Effective at removing chlorine, volatile organic compounds (VOCs), bad odors, and some bacteria. Activated carbon is commonly used in combination with other filtration methods for more comprehensive water purification.

Ceramic Water Purifier:

Process: Ceramic filters have microscopic pores that trap contaminants and impurities as water passes through. They are often used as a pre-filter in conjunction with other purification methods.

Features: Effective at removing larger particles, sediment, and bacteria. Ceramic filters are durable and can be cleaned and reused. They are often part of gravity-based water purifiers.
