To obtain clean and safe drinking water, people began to use water purifiers for water treatment. Many drinking water purifiers are on the market, but not all products can meet your needs. So, which filter is best for drinking water? The following article will give you a detailed introduction.
What is a water filter and how does it work?
A water filter is a water treatment device used to filter water. It can remove impurities, pollutants, and harmful substances in water. Its technical core is the filter membrane in the filter element device. Currently, the main technology comes from ultrafiltration membranes and RO reverse osmosis membranes. It can ensure the health and safety of people's drinking water.
A water filter usually consists of a filter element, filter material, filter screen, inlet and outlet pipes, and other parts. The filter element is the core part of the filter medium. Different types of filter elements have different filtering effects. For example, ceramic filter elements can filter out microorganisms and impurities, activated carbon filter elements can absorb odors and chemicals in water, and ultrafiltration filter elements can filter out tiny harmful substances such as bacteria and viruses.
When water flows through the filter element, the filter element will block and absorb harmful substances such as impurities and microorganisms in the water, thereby purifying the water quality. Different types of filter elements have different filtering capabilities and lifespans, and different types of filter elements need to be selected according to different water qualities.
In general, the working principle of a water filter is to filter out harmful substances such as impurities, particulate matter, and microorganisms in water through the filter medium, thereby achieving the effect of purifying water quality. Choosing the right filter element and replacing it regularly are important steps to ensure the normal operation of the water filter and the effectiveness of water purification.
Filter element type
The types of water purifier filter elements mainly include PP cotton filter element, activated carbon filter element, ultrafiltration membrane filter element, reverse osmosis membrane filter element (RO membrane), ceramic filter element, etc.
PP cotton filter element: mainly used to filter large particles, such as mud, rust, colloid, etc., with uniform and dense pore size, large flow, corrosion resistance, and high-pressure resistance. It is usually used as the first stage of filtration and plays a coarse filtration role. The service life is generally 3-6 months.
Activated carbon filter element: removes organic substances such as discoloration and odor in water through adsorption, including granular activated carbon filter element, sintered activated carbon filter element, compressed activated carbon filter element, etc., mainly adsorbing discoloration and odor, residual chlorine, etc. in water. The service life of activated carbon filter elements is generally 8-12 months.
Ultrafiltration membrane filter element: using a hollow fiber membrane, the filtration accuracy is generally 0.01 micron, which can remove bacteria, viruses, rust, and organic matter in water, while retaining mineral elements in water. The service life is generally 16-24 months.
Reverse osmosis membrane filter (RO membrane): The pore size is very small, only 0.5 millionths of a hair, only water molecules can pass safely, and other impurities such as inorganic salts, heavy metal ions, organic matter (pesticides, hormones), colloids, bacteria, viruses, etc. cannot pass. The filtration accuracy of RO membrane is extremely high and it is the core component of reverse osmosis technology.
Ceramic filter element: Most of them are made of diatomaceous earth mud as raw material and are made by high-temperature sintering. They are mainly used in faucet water purifiers and can be washed repeatedly. The ceramic filter element has a good filtering effect and a certain durability.
These filter element types have their characteristics. According to different water quality and treatment requirements, the water purifier will use different filter element combinations to achieve the best purification effect.

Which water filter is best for drinking water?
ITEHIL reverse osmosis water filter is our first choice for drinking water filtration, with a portable design and electric automatic pump, which can filter drinking water faster and better. The powerful mini self-priming pump can suck and output up to 1000 ml of water per minute. And it also provides intelligent backwashing, the pump backwashes the filter to the non-drinking water outlet to extend the service life of the filter element.
It uses PP cotton + activated carbon + reverse osmosis membrane filter element for multiple filtration. PP cotton can filter out large particles such as sediment and rust, while activated carbon can adsorb impurities such as chlorine and organic compounds, improving water quality and taste by removing odors and pollutants. Reverse osmosis can filter out all harmful substances. Ensure that your drinking water is healthy and safe.
At the same time, the ITEHIL reverse osmosis water filter can also filter fresh water from different environments, allowing you to get healthy drinking water anytime, anywhere. Therefore, long battery life, safety performance, and portable design increase its appeal.
Final Thoughts
You need to decide on the appropriate water filter based on your water quality. The best water filter on the market is the reverse osmosis water filter because it can remove most of the harmful substances. The ITEHIL reverse osmosis water filter stands out with its electric design, purification effect, and portability, providing you with high-quality filtration, and becoming a popular choice for people.
Frequently Asked Questions
How to choose the best water filtration system?
First, you need to understand the quality of drinking water in your area. Different areas have different pollutants in the water quality. Only by deeply understanding the pollutants in drinking water can you better choose a water filtration system. Secondly, when you buy a water filter, you also need to pay attention to the purification effect of the water filter, maintenance cost, brand, and after-sales service, filter replacement cycle, etc. Finally, you need to consider comprehensively according to actual needs.
Which water filter can remove the most pollutants?
ITEHIL reverse osmosis water filter can remove most pollutants. At the same time, it can also remove chlorine, antimony, arsenic, and other pollutants, ensuring that the filtered water is healthy and safe.
