What is the Best Drinking Water Filter?

Working principle of water filter

A water filter is also called water purifier, water purifier, which is a water treatment equipment that deeply filters and purifies water according to the requirements of water use. The water purifier we usually discuss generally refers to a portable filter used for home and outdoor use. Its technical core is the filter membrane in the filter element device. Currently, the main technologies come from ultrafiltration membranes and RO reverse osmosis membranes. The water filter can effectively filter out rust, sand, and gravel, colloids in the water, and adsorb residual chlorine, odor, discoloration, pesticides, and other chemical agents in the water; it can effectively remove bacteria, toxins, heavy metals, etc. in the water. The application of water purification technology in the field of drinking water will make the phenomenon of "water and soil incompatibility" a thing of the past soon, and effectively solve the endemic diseases caused by excessive harmful minerals in groundwater in many places.

Does tap water need to be filtered?

Tap water needs to be filtered. Tap water may contain a variety of impurities, including rust, parasites, microorganisms, heavy metal ions, organic micro-polluted algae, dust, bleaching powder, etc. These impurities are harmful to human health, so it is unsafe to drink tap water directly. To ensure the safety of drinking water, it is very necessary to filter tap water. Filtration can remove impurities and harmful substances in water, improve water quality, and thus protect the health of family members.

Filtration method: Common filtration methods in the home include using a water purifier, which can help filter the hardness in tap water and make drinking water healthier. In addition, installing a pre-filter can coarsely filter the water used in the whole house, clean up impurities and bacteria in the water, and ensure the health and safety of household water.

Filtration effect: Filtered tap water can not only remove residual chlorine, heavy metals, impurities, scale, etc. in the water but also filter out bacteria such as E. coli to achieve the effect of direct drinking. This is especially important for families with babies because filtered water tastes better and children are more willing to drink water.

Note: Although tap water meets national drinking water standards when it leaves the factory, secondary pollution may occur during the pipeline transportation process. In addition, the quality of tap water in different regions may vary. Some tap water will produce a lot of scale after boiling. Therefore, it is best to filter the tap water again when using hot water daily to better protect the health and safety of the whole family's water use.

In summary, to ensure the safety and health of drinking water, it is very necessary to filter tap water.

Which filter is best for drinking water?

Which water filter to use depends on the degree of water pollution. You can choose according to your preferences, but the most suitable filter should have the following characteristics:

Carbon filter: can remove odor, discoloration, and organic matter in water.

Microporous filter: can filter out suspended matter, pollutants, and bacteria in water.

Ion exchange filter: can remove heavy metal ions, lead, copper, and other harmful substances in water.

Ultraviolet sterilization technology: can effectively kill bacteria and viruses in water.

The ITEHIL reverse osmosis water filter uses multi-layer filtration of PP cotton + activated carbon + reverse osmosis membrane, which can remove bacteria, viruses, parasites, heavy metals, pesticides, polyvinyl chloride, PFAS, etc. Its portable design is very suitable for outdoor campers. With it, you can easily get healthy drinking water.

What is the healthiest way to filter tap water?

The healthiest method depends mainly on your needs and budget, but you can filter it through a reverse osmosis water filter and boil it before drinking. The specific methods are:

Boiling: simple, effective, low-cost, can kill most harmful bacteria and viruses.

Tap filter: convenient, affordable, and can remove some chlorine, sediment, and other pollutants.

Water purifier: It has a better filtering effect and can remove most pollutants, including chlorine, heavy metals, drug residues, etc.

Reverse osmosis water purifier: It has the best filtering effect and can remove almost all pollutants, including bacteria, viruses, chlorine, heavy metals, drug residues, etc.

Is it better to buy bottled water or a water filter?

As an outdoor camping enthusiast, it is better to buy a water filter because of the uncertainty of the source and production process of bottled water. Some of them are completed by the ultrafiltration process, and the water quality may also contain microorganisms and chemicals that are harmful to health. Moreover, once the bottled water is opened, bacteria will begin to grow, and it must be drunk as soon as possible, otherwise it will cause water waste. But the water filter is different. The reverse osmosis water filter has high filtering accuracy and can provide safe and hygienic drinking water at any time, and it is ready to drink and filter. No need to worry about drinking water safety.
