Home Water Purifiers

Home water purifiers treat all of your incoming tap water before it circulates throughout the house. They remove contaminants like chlorine, pesticides, heavy metals and more. They also reduce chemicals and carcinogens in your water.


Some home water filters also include a process called water conditioning, which reduces scale buildup in pipes and faucets by binding calcium and magnesium molecules with sodium ions from salt. This system also reduces the need for costly water softeners.


The first step in most home water purifier systems is a pre-filter. This removes large sediments like rust, silt, and dirt from the water, making it cleaner and healthier for home use. It also helps prolong the lifespan of the filter and protects home appliances from clogs. These sediments can also add color and unpleasant odors to the water, as well as leave stains on clothes. Pre-filters help eliminate these particles and improve the flavor of the water.

The RA-PRF-2 is a whole house spin down sediment filter that can be used in conjunction with most home water filtration systems. It is designed to keep appliances like washing machines and water heaters free from clogs and extend their lifespan by removing large impurities from the water before it passes through the filtration system.

It is made of a spun and woven polypropylene filter multi media with a high dirt-holding capacity to ensure the best quality of water. The sediment filter is the most important part of a home water filtration system because it protects other filters from clogs and improves the overall function of your appliances. It also increases the longevity and efficiency of your appliances, which will help save you money in the long run. The best part about the sediment filter is that it is affordable and easy to install and maintain.

Activated Carbon

Activated carbon is probably the most familiar of all home water filters, being the “technology” found in inline and countertop water filters. It’s also a common pre-treatment to a reverse osmosis system to reduce many organic contaminants and chlorine.

Unlike most filters, which physically trap particles, activated carbon uses chemical absorption. Its large surface area attracts and traps organic molecules, atoms and ions, much like a sponge soaks up water. In fact, one gram of activated carbon has a surface area of about 125 acres (about the size of a tennis court).

The pore structure of the carbon determines its ability to remove contaminants from water. The smallest pores allow the carbon to be used as a parking lot for the impurities that it absorbs, while the larger pores are best for removing ions and bigger molecules. Activated carbon is commonly made from coconut shells, nutshells, coal and wood, which are burned to create a material that can be ground into granules for use as a filtering medium.

There are many factors that affect the effectiveness of a particular type of carbon for a specific application, such as molasses number, water hardness, temperature, pressure drop and particle size. General Carbon offers different sizes of carbon to fit a wide variety of applications, depending on the size of the particle required to treat a vapor or liquid stream. Larger particles are generally used for vapor applications to reduce pressure drop, while smaller particles are more appropriate for liquid applications to reduce the distance that the chemicals need to travel to be adsorbed by the carbon.

Ion Exchange

Ion exchange is a tried and true water treatment method that is often used in conjunction with water softening. It is a process that exchanges undesirable ions, like calcium and magnesium (which cause water hardness), for desirable ions, such as sodium. The unwanted ions are trapped on a resin bed and the desirable ions allow clean, healthy water to pass through.

These resin beds are essentially miniature polystyrene beads that are permanently charged with less objectionable ions. Typically, they come in two forms: cation and anion. Cation resins, whose ions are positively charged, are able to swap the unwanted ions for hydrogen (H+). Anion resins, on the other hand, can replace negatively-charged anions for hydroxyl (OH-) ions.

Both cation and anion resins will eventually become depleted of desirable ions, and they must be regenerated in order to continue working effectively. When this happens, the resin is flushed with a liquid that removes the unwanted ions and refills the resin bed with desirable ions.

Ion exchange systems are a great choice for removing harmful contaminants, including strontium, from drinking water. Strontium is an alkaline earth metal that can cause skeletal and dental problems in humans when found in high concentrations in drinking water. It is also linked to leukemia and bone cancer. In addition, ion exchange can be used to remove fluoride and radium from drinking water.

Reverse Osmosis

Reverse Osmosis is a seven stage process that takes your tap water through a series of filters to clean it up to the molecular level. This gets rid of most organic chemicals and minerals (including arsenic, chromium-6, chlorine, lead, nitrates from fertilizers and radiological contaminants) as well as bacteria, viruses and other microorganisms.

This popular system is designed to be installed under the sink in about an hour by anyone with basic DIY skills. It comes with everything you need including a pressurized tank and faucet that is designed for easy filter changes without the use of tools. It also has a LED indicator that glows blue to indicate all systems are functioning properly and red to warn you that one or more of the filters needs to be replaced.

It uses a polypropylene spun sediment filter to remove larger molecules and ions from the water before it goes through reverse osmosis. This helps extend the life of the membrane and carbon filters.

It also uses a pre-inline carbon block to further reduce chlorine, bad tastes and other chemicals from the water. This prevents them from leeching into your final product. Finally it uses a reverse osmosis membrane to get rid of dissolved inorganic and organic materials. This is what really makes the water pure down to the molecular level.
