Water Filters: What Are They?
The first thing to understand about water filters is that they are not meant to remove all contaminants from your drinking water. You still need to keep them safe from pathogens and other harmful substances like chemicals or heavy metals. A good quality water filter will have a high level of filtration capacity, which means it can remove more than 99% of microorganisms, bacteria, viruses and protozoa (smaller forms of bacteria).
In fact, the term “filtering” refers to the process of removing particles larger than 0.3 microns (0.003 mm) in size from drinking water.
These tiny organisms cause many diseases such as cholera, dysentery and typhoid fever among others. Other types of contaminates include heavy metals like lead and arsenic; chlorine compounds like chloramine; organic compounds like nitrates and phosphates; and even bacteria that cause stomach ulcers!
There are two main types of water filters: reverse osmosis and ultraviolet light (UV). Reverse osmosis systems use membranes made up of very fine pores called sieves. When these membranes pass through a solution containing microorganisms, they block out the microorganisms’ food source, which results in their death.
UV systems work differently. Instead of blocking out microorganisms, they absorb some of the energy that is used by the microorganisms to survive. They can be placed directly on the faucet or on the pipe that carries water in your home.
How Do You Choose the Best Water Filter?
The first step is to check with your local or state health department as to what the minimum standard of filtration they require for drinking water. Many states have their own set of standards, so make sure you familiarize yourself with those. Once you know this, you can then begin your search for the best water filter.
There are so many types and brands of water filters available on the market today that choosing one can be quite overwhelming. Start by looking online or searching through your local newspapers, magazines and bulletins for any information about various water filters and the companies that sell them. You can also talk to friends, family or neighbors who have purchased a water filter in the past as they may have recommendations.
Next, check the prices of the different water filters and buy only those within your price range. While it may be tempting to choose the most expensive model, it might not be necessary if your main concern is the removal of chlorine or other chemicals. In fact, some of the cheapest filters can remove these chemicals quite effectively if they come in the form of grains, pebbles, granules or crystals.
It’s also important to consider the size of the water filter you need.
Do you need one that can be fitted on your kitchen sink, or will one for your refrigerator do?
Perhaps you just need something portable that can be carried around. The size of the filter should match your needs.
Lastly, consider the longevity and reliability of the water filter you choose. Not all water filters are built to last, so it is important to check customer reviews online or speak to previous customers before making a choice. It is also a good idea to buy water filters that come with a money-back guarantee just in case the product fails to meet your expectations or breaks down prematurely.
With these tips in mind, you should have no trouble at all when choosing and buying the right water filter for your home or place of business.
