Purchasing Doulton Water Filters
By Tony Cunningham

Countertop Or Under The Sink Units

Doulton water filters are available in a variety of sizes and uses; they are also available for both residential and commercial use. The residential water filters can be found in all varieties to purify water a picture at a time or for the entire household.

Popular Doulton water filter choices are the varieties which are installed under sinks; they have the ability to filter about one thousand gallons of water between filter changes. These filters are available in three to five stage filtration systems; the three stage systems filter lead, iron, and hydrogen sulfates.

Three stage filtration systems are able to provide the same quality water available by reverse osmosis, distillation, and ultra-violet technologies. Purchasing a three stage under the sink Doulton water filtration system could be more economical than purchasing bottled water by the gallon or in individual bottles.

Four Stage Doulton water filtration systems are designed to remove dirt, chemicals, microbiological, and nitrate reduction or some filters reduce MTBE instead of nitrate depending on a household's needs.

Five stage Doulton water filtration systems are able to filter even more pollutants from household drinking water; the five stage filters remove fluoride, iron, lead, MTBE, and nitrate from the water coming from the household tap. MTBE is Methyl-tertiary-butyl-ether a common additive to gasoline commonly found in drinking water; while it is often in trace amounts it can affect the taste and smell of the water.

Whole Home Filtration

Whole home Doulton water filtration systems are also available, they are able to reduce basic impurities for the entire home from one unit; they are often installed where the point of entry for the household is located.

Because these Doulton water filtration systems are able to clean such large amounts of water, they sometimes aren't able to reduce as many contaminates as the smaller counter top or under the sink units. The reason is water pressure; to allow sufficient water pressure throughout the house there have to be large enough gaps between the fibers of the filters to allow larger amounts of water to pass.

Keeping that in mind, knowing when to replace the filter for a household's Doulton water filtration system becomes easier; if the water pressure decreases the filter is clogged and will need to be replaced. This should only happen every three to four months in a home with two or less bathrooms.

For most home owners a countertop or under the sink unit is sufficient for a households needs; it is a good idea to test the tap water to determine the household's exact needs before purchasing any water filtration unit. The counter top or under the sink Doulton water filtration units are the most practical because most of the water people ingest is from the kitchen tap.
