What order do water filters go in?

The water should first go through a sediment water filter to reduce sand, dirt, rust, and other sediment. You want to have the water go through a sediment filter first so it does not clog up the carbon filter, which is more expensive. The sediment filter will prolong and protect the carbon filter.

Today, carbon filters are a leading player in water filtration. It is possible that activated carbon block filters have unique properties that can effectively remove up to 99 percent of total suspended solids, volatile organic compounds, sediment, heavy metals, chloramines, and other contaminants from drinking water.

Water filtration systems remove dissolved ferrous iron by ion exchange, and they remove ferric iron by filtration. It is essential to remove the ferric hydroxide periodically from the water softener bed because it can cause clogs that reduce the effectiveness of the ion exchange.

You’ll want to make sure that you place your filter on the pressure side of the pump, after the pressure tank. This helps to ensure that you’re protecting the pump. It also allows the filter to be cleaned without losing any pump prime.

An iron filter should be used when water contains a high concentration of inorganic iron, whether ferrous or ferric, or when organic matter is also present.

Iron will clog pipes, reduce household water pressure, ruin the taste of tea and coffee, and leave bright-colored stains on your appliances in quantities as small as 3ppm (parts-per-million).

The iron filter needs to be installed after the pressure tank. If it is installed before the pressure tank, it will not be able to backwash automatically. The filter needs varying amounts of flow and pressure.

The best overall whole house filter for removing high levels of iron in well water is the Pelican Water Iron Filtration System.

Reverse osmosis filter systems are some of the strongest, most effective filters for drinking water. They are known to remove more than 99% of most dangerous contaminants in the water. That includes heavy metals, herbicides, pesticides, chlorine and other chemicals, and even hormones.

Usually, the best place for a whole house water filter is near your main water shut-off valve, which is usually located in a basement or on the perimeter of the house in a utility closet or other such area if you don’t have a basement.

The two most common types of filtration systems for residential use are systems using reverse osmosis or activated carbon filters. Both of these systems are effective at removing contaminants, but the exact type of contaminants they remove are different.

As for sediment filters, you should definitely place them before the pressure tank. In fact, they should be the first in line, preventing sediment from entering into any other water filtration or treatment equipment you have installed (like water softeners, water heaters, etc.).

Some specialized water filters, such as typical iron filters, also need to be backwashed. These filters are usually installed before a water softener, so you need to make sure there’s a good enough flow rate to the water softener while the system is backwashing.

The only safe and effective way to remove iron from the water is by utilizing an iron filter. A Katolox filtration system is able to remove both forms of iron, magnesium and hydrogen sulfide present in well water.

Install the filter on the water supply line just before it enters your water softener. You may want to install yours with a bypass line so you can change the filter while the water is being used in another part of the house.
