Point-of-use filters for home use include granular-activated carbon filters (GAC) used for carbon filtering, depth filter, metallic alloy filters, microporous ceramic filters, carbon block resin (CBR), microfiltration and ultrafiltration membranes.
Some filters use more than one filtration method. An example of this is a multi-barrier system. Jug filters can be used for small quantities of drinking water. Some kettles have built-in filters, primarily to reduce limescale buildup.
Flowmatic cartridge style filters are cylinders 10 inches (254 mm) long by 2.5 inches (64 mm) in diameter. They are made by multiple manufactures and are available in 1-50 micron ratings as well as activated carbon.
Point-of-use microfiltration devices can be directly installed at water outlets (faucets, showers) in order to protect users against Legionella spp., Pseudomonas spp., Nontuberculous mycobacteria, Escherichia coli and other potentially harmful water pathogens by providing a barrier to them and/or minimizing patient exposure.

The term water polishing can refer to any process that removes small (usually microscopic) particulate material, or removes very low concentrations of dissolved material from water.
The process and its meaning vary from setting to setting: a manufacturer of aquarium filters may claim that its filters perform water polishing by capturing “micro particles” within nylon or polyester pads just as a chemical engineer can use the term to refer to the removal of magnetic resins from a solution by passing the solution over a bed of magnetic particulate.
In this sense, water polishing is simply another term for whole house water filtration systems.
Polishing is also done on a large scale in water reclamation plants.
ACTIVATED CARBON FILTERS
These are also known as carbon filters or pre-filters and are generally responsible for removing larger particles like sediment and silt from your water.
They work by attracting and absorbing these particles so they’re no longer present in the liquid that comes out of your faucet.
An activated carbon filter will also make sure the end result has less in the way of odor and tastes much better. This is because they reduce the amount of chlorine and other contaminants that can make your water smelly or just darn right unpleasant to drink.
Reverse osmosis (RO) is a water purification technology that uses a semipermeable membrane to remove ions, molecules and larger particles from drinking water.
In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property, that is driven by chemical potential differences of the solvent, a thermodynamic parameter.
Reverse osmosis can remove many types of dissolved and suspended species from water, including bacteria, and is used in both industrial processes and the production of potable water.
The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side.
To be “selective”, this membrane should not allow large molecules or ions through the pores (holes), but should allow smaller components of the solution (such as solvent molecules) to pass freely.
In the normal osmosis process, the solvent naturally moves from an area of low solute concentration (high water potential), through a membrane, to an area of high solute concentration (low water potential).
The driving force for the movement of the solvent is the reduction in the free energy of the system when the difference in solvent concentration on either side of a membrane is reduced, generating osmotic pressure due to the solvent moving into the more concentrated solution.
Applying an external pressure to reverse the natural flow of pure solvent, thus, is reverse osmosis. The process is similar to other membrane technology applications.
However, key differences are found between reverse osmosis and filtration. The predominant removal mechanism in membrane filtration is straining, or size exclusion, so the process can theoretically achieve perfect efficiency regardless of parameters such as the solution’s pressure and concentration.
Reverse osmosis also involves diffusion, making the process dependent on pressure, flow rate, and other conditions.
Reverse osmosis is most commonly known for its use in drinking water purification from seawater, removing the salt and other effluent materials from the water molecules.
DRINKING WATER PURIFICATION
Around the world, household drinking water purification systems, including a reverse osmosis step, are commonly used for improving water for drinking and cooking.
Such systems typically include a number of steps:
a sediment filter to trap particles, including rust and calcium carbonate
optionally, a second sediment filter with smaller pores
an activated carbon filter to trap organic chemicals and chlorine, which will attack and degrade thin film composite membrane reverse osmosis membranes
a reverse osmosis filter, which is a thin film composite membrane
optionally, a second carbon filter to capture those chemicals not removed by the reverse osmosis membrane
optionally an ultraviolet lamp for sterilizing any microbes that may escape filtering by the reverse osmosis membrane
Water Filter Housings are POE (Points of Entry) and POU (Points of Use) products. Being used for building filter systems (including reverse osmosis),
Filter Housings can protect your entire water system, and besides, being installed in front of costly appliances, acting as a barrier against the accumulation of several contaminants
