It is a water filter which helps decontaminate water by either using a physical barrier, chemical process or biological process.
To help you understand and further clarify the several types of filtration system options you can choose from, we have listed the different types of filters and their pros and cons below.
A fiber filter is made using rayon, cellulose or other similar micro-fibers which are then spun into a perforated mesh. Pressrised water is passed through these fibers which have been wrapped tightly around the filters. For the best and most efficient purification results, select a fiber filter that has a micron rating lower than1.
Sediment, muddiness and small organic particles that cause bad odors and taste are also be removed.
Dissolvable impurities such as lead, chlorine and mercury are not removed this filter.
Solid Block Activated Filter/Charcoal Filter
The carbon in these filters has been specially treated, compressed and bonded. This allows the filter to perform absorption at a high level. Not only that, its unique treatment allows it exceptional particulate filtration which other purifying methods cannot match.
Much more effective and complete compared to granular activated carbon filters, as surface area is larger and contact time is longer.
Soluble salt like nitrate and fluoride is not naturally reduced.
Distilled water is pure water that is obtained by a process that captures the pure steam from boiling water, which turns to liquid form again through condensation. A vapour trap, carbon filter, or other device should be used along with a distiller to ensure a more complete removal of contaminants.
The nature of the filtration process is such that even extremely poor quality water can be filtered and safely used for drinking.
Extremely long time reuired to collect usable amounts of water. For example, it may take half an hour or longer to get 1 cup’s worth (250ml) of distilled water.
In a UV water purifier, Ultraviolet light is used in a clear, reflective chamber where the water is passed. UV light effectively destroys bacteria and viruses. However, a key factor affecting the potency of the UV system is just how much of the UV light is absorbed by the microrganisms. The higher the absorbtion, the better the efficiency.
Zero toxic byproducts. Many types of bacteria, virus and microorganism are wiped off.
Mostly effective on microorganisms. This means that it is unable to purify impurities like asbestos, chlorine and lead.
A clear plastic barrier like a plastic bag, ground cloth, or a plastic grocery sack is placed over the water source. The sun passes through the barrier and heats the source which then vaporizes, rises and then condenses on the underside of the plastic barrier. The moisture collected is drinking water.
Capable of distilling almost any tainted water including seawater.
The process is higly time-consuming. Therefore, it take a long time to collect sufficient amounts of water for daily usage.
