Top 5 Types of Drinking Water Filters – Purity

Making decisions may be stressful, but sometimes a choice, such as selecting a loaf from the bread aisle, will only go you so far. Choosing a water filter for your house, for example, is an essential decision at times.

Nobody wants to invest money in a water filter only to discover that it answers an issue they don’t have. However, with so many water filtration choices available, it can be difficult to choose the appropriate one for your house – the one that not only improves the flavor of your water but also removes the greatest number of impurities.

Don’t be concerned. It’s a lot easier than you think. The following is a list of the most common types of water filters on the market to assist you in making an informed decision about which water filters are best for your household.

Before getting into the details, bear in mind that diagnosing the “issue,” or in this case, assessing the current quality of tap water, is critical before selecting a filter. Tap water varies by location, and depending on where it comes from, it may or may not be treated for a variety of impurities.

Here’s a list of five popular water filtration types on the market.


Adsorption is the key to understanding how activated carbon works. Adsorption happens when one material adheres to another while passing through, as opposed to absorption, which occurs when one material absorbs or soaks up another. Activated charcoal, often known as activated carbon, is made up of this substance.

When organic material with a high carbon content (such as wood, coal, or coconut shells) is heated in such a way that it does not burn but instead produces char, the result is activated charcoal. The char is then processed to generate a porous substance that binds to toxins and contaminants in the water running through the system, effectively removing them.

This is the most common type of filter and often used in conjunction with other filtration methods for maximum toxin removal. Aquasana Whole House Filter Systems, for example, are activated carbon filtration systems that incorporate a salt-free water conditioner, copper-zinc and mineral stone, and UV for maximum filtration.

Ion exchange filters, as the name implies, are made up of a material that will exchange one ion for another when water passes through it. Ion exchange, for example, will substitute sodium ions for calcium or magnesium ions, which create water hardness. The water will be “softened” as a result of this. If the water in your house leaves stains on washed dishes, you may have hard water. Hard water has a tendency to build up in pipes, reducing the life of several kitchen gadgets.

Ion exchange filters assist with hard water and certain radioactive material, but they don’t remove organic material, particulates, or germs as well as other filtration alternatives.


Reverse osmosis filters are quite popular for a reason: they get a lot of bang for your money. Reverse osmosis filters are the most effective in removing a substantial percentage of pollutants from water, including potentially hazardous microorganisms.

The filters function by applying pressure to water as it passes through the reverse osmosis membrane. Fresh water is forced to the other side of the film, while pollutants stay on one side. It’s one of the few filters that can remove pollutants like fluoride and chromium +6 from water. An RO system will remove the salt from drinking water if a residence has a water softener.


Mechanical filters are frequently employed as a first step in the filtration process. Waste material becomes trapped between nylon floss, synthetic foam, or pads as water runs through a mechanical filter. In a fish tank, for example, the filter will collect plant debris, leftover fish food, and trash but not beneficial bacteria that is useful to the fish.


UV filters, which use multiple frequencies of ultraviolet light to purify water, are an environmentally beneficial solution.

The UV light is absorbed by the DNA in microbial cells, thereby killing all bacteria and viruses and sterilizing drinking water. UV filters only remove bacteria and viruses from water; thus, you need use this filter in conjunction with other filters to remove common toxins like chlorine, lead, and pesticides, leaving you with clean, drinking water.

There are many advantages to filtering your home’s water. In addition to removing contaminants, filtering your water can help your body to absorb vital nutrients, detoxify your body, increase your water consumption, improve the taste of your cooking, give you healthier skin and hair, help the environment, and save you money.
