Is the pre-filter more expensive than usual? What do you mean? Is it said that the pre-filter will cost more water than usual? The front filter is a primary filter for the water entering the household, removing large particles such as sediment and rust in the water. Generally, the filter accuracy of the front filter is about 40 microns, mainly depending on the filter element, it can also reach 5 microns. The pre-filter will be more expensive because there is waste water discharged. Generally, the pre-filter needs to be cleaned after a period of use, and there are manual cleaning and automatic flushing, when the filter is washed, some water will be mixed with the dirt on the filter element to discharge the wastewater. Otherwise, I don't know where else the wastewater will be compared.

Which water purifier is good, how about the front filter of boshikang water purifier, has anyone used it, what is it used. The front filter is suitable for areas with poor water quality, and the tap water is pre-treated to reduce the burden on subsequent water purification equipment. There are two main types of water purification machines: ultra-filtration and reverse osmosis. The latter is suitable for almost all water quality, but the wastewater rate is high. Mainstream brands on the market are OK, many consumables are universal. The Emperor Ming I use is very good! This brand has not been used. the front filter only filters some sand or something. like the small virus, it is not filtered at all. it mainly depends on his permeable membrane. Huangming's reverse osmosis membrane filtration accuracy is 0.0001 microns. Can filter out the bacteria
