Household water purifier has become a kitchen appliance of utilization rate is very high, the water purifier to purify water, filtered out the harmful substances in the water, after drinking to the body more healthy.However, water purification machines also need regular maintenance, water purification machine filter need to be replaced periodically, so as to fully guarantee the purification effect of water purification machine.So, the filters filter life how to judge?How to maintain clean water machine? 1, water purifier filter service life how to judge? At present domestic normal water purifier manufacturer can give the service life of the water purifier filter a reference, such as ultrafiltration membrane generally are given 24 to 36 months;Reverse osmosis (RO) membrane life at 18 months or so commonly, adsorption of filter, such as activated carbon filter in about six months to 1 year, no filter filter such as the discharge of pollutants by pp cotton, generally 3 months.However our country water quality are relatively complex, so the service life of the reference is generally based on urban tap water, water use, water quality of the usual maintenance and water purifier installation environment and so on to determine the service life of the water purifier filter;Part of this water purifier manufacturers is based on the actual water yield of water purifiers to determine, this approach is also commonly the testing results of the tap water in the city water environment;These theories are not, of course, on behalf of the water purifier filter service life in the practical life, the actual service life of filter still have great relationship with maintenance. 2, water purifier filter maintenance rule: First, if ultrafiltration filter, RO and NF filter, first before use must be on the inside of the water purifier filter to wash, to wash filter inside the protection of the fluid. Second, washing: the water purification products on the market now have clean water machine, pure water machine, filter press three, different water purification products made from a mix of different filter, the product in the use of a certain period of time, will generate too much impurity, blocked filter, and so on and so forth. Third, when the water yield less than the original half way can apply to the after-sale service center repair station for maintenance. Fourth, the medicine can be used to wash or cleaning backwash. 3, water purifier filter what circumstances need to change, how do you know whether or not to change the filters filter? First, super filter, ro membrane replacement: when water purifier water rate is greatly reduced, much smaller than the original flow or water, are washed still cannot restore, already can’t meet your demand, this time will need to replace filter. Second, active carbon composite filter replacement: when do you think of the taste of water purification and can’t accept, need to replace the composite filter, such as installing or replace more than a year, no matter use frequency of high and low, are changing. In fact the water purifier filter determines the health of drinking water at home, if the filter will not be changed for a long time it may on the filtered water "secondary pollution", so the water purifier in daily use must maintain and replace filter.Filter out small, generally does not mean filter quality is bad, the main reason is that water down or bad is the original water filter clogging.In many cases, a combination of both. |
