YIJIA Health recommends that before purchasing a water filter, it is necessary to understand the types of water filters and understand the performance characteristics of each water filter. The following is an introduction to the types of water filters that are commonly used at home and have suitable effects.

Ultrafiltration water filter is the most popular type of water filter on the market. Its core is to filter out harmful impurities in water through an ultrafiltration membrane, and the core technology is an ultrafiltration membrane. Ultrafiltration membrane is a membrane similar to PVC with very fine pores, the smallest pore size is only 0.01 microns.

Most of the harmful impurities in the water, such as sediment, rust, bacteria, microorganisms, etc., can be intercepted and filtered by the ultrafiltration membrane, while the beneficial trace elements such as zinc, calcium, manganese, strontium, etc. in the water can be retained.

This kind of water better retains the activity of natural water and is the most suitable for human drinking. However, ultra-filtered water cannot be drunk directly, it must be boiled before drinking.

In addition, the ultrafiltration water filter does not produce wastewater and does not require electricity, so it is more suitable for areas with relatively good water quality.

The RO water filter has a higher purity than the ultrafiltration water filter. It intercepts almost all tiny components through the reverse osmosis membrane with smaller pore size. Except for water molecules that can pass through, all other components can be intercepted, because Its pore size reaches 0.000001 microns, which is only slightly larger than a water molecule. Therefore, beneficial components such as trace elements in the water cannot pass through the RO reverse osmosis membrane.

Unlike ultrafiltration, reverse osmosis requires electricity and produces a large amount of wastewater. Of course, this water can be used for other purposes, such as laundry, mopping, toilet flushing, watering flowers, etc.

The activated carbon composite filter element water filter uses the activated carbon filter element as the main body to filter tap water in combination with various other filter element materials, so as to obtain healthy and clean drinking water.

Activated carbon is a very good adsorbent. It is processed and manufactured by using charcoal, bamboo charcoal, various fruit shells, and high-quality coal as raw materials. It has the dual characteristics of physical adsorption and chemical adsorption, and can selectively adsorb air or water. In order to achieve the purpose of decolorization and purification, disinfection and deodorization, decontamination and purification, etc.

The organic pollutants in the water, including the residual chlorine of bleaching powder, exist in the molecular state and must be absorbed by activated carbon. Therefore, the ultrafiltration and RO reverse osmosis mentioned above are often equipped with multi-stage filter elements. Among them, activated carbon is indispensable.

A nanofiltration water filter is a kind of water filter between ultrafiltration and RO reverse osmosis. The microporous structure of its core nanofiltration membrane reaches nanometer level, generally 1-2 nanometers, which is relative to the RO membrane. In terms of selective interception of some substances, the interception rate of RO is above 95%, and that of a nanometer is below 90%, which can partially retain some beneficial components. In principle, healthier water can be obtained.

However, due to the uncertainty of domestic water pollution, the market still tends to be more RO or ultrafiltration, and the market space for nanofiltration is relatively small.

The faucet water filter is the simplest kind of water purification equipment. It has a very small structure and can be used directly on the water head. It only performs preliminary filtration of tap water through a simple primary or secondary simple filter element, mainly to remove impurities such as sediment and rust.

From the core point of view, there are only the above five types of household water filters. The combination of various filter elements on the market seems to be complicated, and they are inseparable from ultrafiltration, reverse osmosis, or nanofiltration.

There are many other filter elements. It is a pre-filter and a post-supplement. On the one hand, it is used to protect the core filter to prolong the service life, and on the other hand, it can remove the smell and obtain a better taste.
