The natural cycle of water replenishment on earth is through rain. All of the oceans, rivers, lakes, streams and all other bodies of water that exist are filled by rainfall. This is why if rain does not fall for a long time, it will affect almost every part of earth’s complexly connected ecosystem. Rain itself comes about through a cyclical evaporation process and can be an excellent alternative water source.

With periodical droughts affecting the reliability of water supplies in some places, water is becoming more precious than ever. Water use all over the world is higher than ever. This is for many reasons, including both general population increases and higher population densities in growing or new urban areas, as well as changing lifestyles that mean individuals are using more water than ever before. Environmental activists and some governments’ have encouraged people to use rainwater tanks as an alternative or supplemental water source.

Rainwater collection systems are most often designed to capture rainwater from roofs. This is the most common means of rainwater harvesting because it provides an efficient means of gathering rainwater for residential purposes. However because of the risk of contamination when collecting water from an exposed outside area, there is a need to make use of a specially designed and balanced filtration system.

The rainwater harvesting filter accessories carry out pre-filtration of the rainwater before it is used for household purposes. After proper filtration it would be safe for domestic purposes like filling the swimming pool, running the washing machine and flushing the toilet, among others. There are different kinds of rainwater harvesting filters that can be used for rainwater tank systems. Each of these filters has different applications, as well as varying limits to the level of filtration they provide.

Pot filters are very simple means of filtering rainwater. They have minimal maintenance needs and can capture and filter 100% of the rainwater that falls on the place they are installed. They are one of the most commonly used rainwater harvesting filters.

Another commonly used rainwater harvesting filter system is the basket system which has a large screened filter basket that fits within a plastic filter body. Most of these basket filters can filter 100% of the rainwater from a roof of up to about 5,000-10,000 square feet. It is also very easy to maintain and relatively affordable.

Vortex filters are also reliably efficient rainwater harvesting filter systems. These filters collect rainwater and allow it to flow in through the upper part, after which the water spins around the perimeter of the filter body and spills into the filter element. It does not collect debris like the other systems and requires little maintenance, although it cannot capture and filter up to 100% of the rainwater as some other filters can.

Most suppliers of rainwater tanks also sell various rainwater harvesting filters. They can also advise customers on the best type for them to use and the particular benefits for your individual circumstances. The prices are also affordable, considering the ongoing benefits that these kind of products offer to the user.
