Before it reaches us, most of the water that we use for drinking, cooking, bathing, and washing has been treated using one or more different types of water filters. These water filters protect us from hazardous chemicals and toxins like bacteria and pesticides while also removing sediment, smells, discoloration, and disagreeable tastes from the water.

Your area’s water’s biochemical characteristics, water pressure, the sort of pipelines it passes through, and even the water source for your house all have an impact on what’s in your water. Even if your water comes from a private well, you still have to make the crucial decision of how to treat, filter, soften, and purify the water since the Environmental Protection Agency does not control every pollutant that can be present in a public water supply.

The purpose of this post is to introduce you to the most popular types of home water filters reviews. The common techniques for water filtration and purification are then discussed. We’ll also go through each type’s advantages and disadvantages so you can decide which is ideal for your house.

Activated Alumina

Activated alumina (AA) is the ideal filter to use if you need to remove fluoride or arsenic from your water. This extremely porous ceramic material, which is made of aluminum oxide, has a high capacity for adsorption—not absorption. As a result, when chemicals are drawn to AA’s activated porous sphere, they aren’t simply retained inside the pores; they also form bonds with one another.

Because of this property, AA is an economical solution for removing metals and poisons from polluted water without running the danger of these materials escaping back into the environment. The more dangerous compounds that AA can remove, the longer it is in touch with your water.

Toxic waste remediation, industrial uses, water treatment facilities, and residential water filtration can all benefit from the usage of activated alumina.

Activated Carbon

A type of carbon that has been treated to increase the number of holes on it is called activated carbon, also known as activated charcoal. The pores of an activated carbon filter catch the pollutant molecules when water passes through it.

A lot of surface area may be absorbed by activated carbon. The substance is frequently used in water treatment to eliminate organic compounds or remove chlorine. When used as a pre- and/or post-filter in under-sink and whole-house filtration systems, it might be the only medium in a pitcher.

Alkaline and Water Ionizers

One of the best water purification methods is alkaline or ionized water, which is thought to provide advantages including healthier skin, better bones and digestive health, a lower risk of cancer and heart disease, greater hydration, and better flavor.

Ionized water’s electrically charged minerals separate the alkaline from the acidic water, making the water softer and better for drinking. Alkaline ionizers do not have strong filtering capabilities, thus you should use them in conjunction with other water purifiers.

Ceramic Filters

Any material larger than the microscopic holes on a ceramic surface will be trapped by the pores, keeping it out of your water. These filters are cheap, easy to use, easy to install, and don’t require energy. A ceramic water filter may also eliminate germs and stop mold and algae growth if it has been treated with silver. They are ineffective at removing viruses, though, because they cannot move any quicker than they can filter.


In a manner similar to the precipitation cycle, water is heated into steam, cooled, and then returned to liquid form in a clean container through the process of distillation. The procedure eliminates microorganisms while also enhancing the flavor and odor of treated water.

The good news is that you can finish the distillation procedure using a variety of countertop tools, and after it’s done, you’ll have water that is safe to drink. The procedure is extremely sluggish and does not win for efficiency because it needs energy or a heat source to function.

Reverse Osmosis

This technique involves pushing water against a semipermeable membrane, which lets water pass through but keeps out any toxins, chemicals, metals, or parasites the water could be carrying. RO filter systems are very good at removing dangerous contaminants from your water.

They tend to waste a lot of water in the purifying process, only cleaning a tiny part of the total amount of water utilized, and are often more expensive than other types of water filters. They also require high water pressure to work.

Ultraviolet Light

One of the most secure and efficient methods for eliminating viruses, germs, protozoa, and parasites from your water is UV light. High frequency UV light radiation strikes water and travels through a glass component. The cost of this filtering process is on the higher end and it takes electricity to operate.

The optimum time to utilize UV lamps as water purifiers is towards the end of the water treatment process when the water has been most thoroughly filtered. This is because non-organic impurities can’t be removed by UV light, which reduces the efficiency of UV lamps.
