Water contaminants are one of the leading causes of illnesses and diseases worldwide. Imagine having to use water and worrying about it being contaminated or not, and having to constantly go through lugubrious processes to test if the water is suitable for drinking, cooking, recreational, and aesthetic activities like swimming and aquariums, respectively, No! The dynamic technologies of our world today have made it easier to leapfrog these problems.
Best Water Filter for Contaminants
There is a particular gadget that serves that purpose now, which by its design and features can be portable and sometimes doubles as a water tester too, and this miracle gadget is called a Water filter.
Water filters, unlike sieve or screens, are capable of removing even smaller particles much smaller than holes through which its water passes.
Water filters are essential tools needed to escape the problem of contaminants in water; Filters are used most commonly to clean water that can serve for different purposes such as; drinking, swimming pools, and aquariums by removing dirt, it reduces contamination of water using a physical barrier and sometimes combined with a chemical or biological process.
But just like every other household machine out there, there are different types of water filters, which by characteristics of purpose, processes, and distinguished features involved, there exist individual preferences as to what kind of water filter one might find most suitable. But, to make this choice, you need to know various types of water filters, and the purpose and unique features each has.
Types of water filters system
Activated Carbon Filters: Removing larger particles like sediment and slit from your water, thereby effectively treating and making it suitable for consumption, is one major characteristic of activated carbon filters.
These types of filters, also known as carbon filters or pre-filters, helps to achieve this by absorbing and attracting particles, so they are no longer present in the liquid that comes out of your faucet.
An activated carbon filter will also make sure to get rid of unpleasant odor and improve tastes to make it suitable for drinking. This is because they reduce the number of other contaminants and chlorine.
Reverse Osmosis: The ability to remove all sorts of contaminants makes this type of filter incredibly popular. Removing contaminants is attained by the process of using a partially permeable membrane to remove larger particles, unwanted molecules, and ions from drinking water using applied pressure to over osmotic pressure.
Alkaline/Water Ionizers: This process is majorly used to obtain water that is low in acidity by electrolysis. The water is passed over electrodes, which are electrically charged and separated into two streams ( alkaline and the other is acidic). The result is a softer and less acidic water, which has been proven to be very good for the skin.
UV Filters: These being one of the best environmentally friendly way of removing contaminants from water is one of the newest technologies in the market, because it doesn’t involve any chemical or heat to be effective. Treating water with ultraviolet radiation destroys various bacteria that are detrimental to health.
Infra-red Filters: Similar to alkaline filters, the major importance of this type of filter relies on its ability to soften water by using light and heat to negatively charge the water, making it soft and suitable for use. This is relevant in most areas where hard water is predominant.
But then, you are in the market or want to shop online, and you are wondering about the best water filter you could buy considering efficiency, cost-effectiveness, durability, and easy usage; Below are the top five best water filter you can purchase judging from personal usage and numerous user experiences.

Conclusion: Choosing the best water filter to use:
In choosing the best water filter to use, there are certain things to be taken into consideration. One of which includes the purpose it is intended for.
For instance, One that intends installing a water filter for municipal use must take note of the capacity the filter is capable of purifying per unit time, a CuZn UC-200 Under Counter Water Filter would do in this case. Another point of consideration is the ease of installation.
Installation requires an expert, and sometimes they won’t be at your disposal; this is the more reason for choosing a water filter that is easy to install is very important. The type of contaminants to be treated is also an important parameter.
Water contaminants are categorized into organic (which includes herbicides, detergents, debris, chlorinated solvents, etc.) and inorganic substances (including ammonia form, insoluble plastics, fluoride, chloride, arsenic, etc.).
Water filters also differ according to the types of the contaminant that is to be treated, therefore, in choosing a suitable water filter, one must have fore-knowledge of the contaminants to be treated for and must ensure it matches the capability of the water filter to be used.
