Q:Can the filtered water of the tap water filter be used directly without water storage?
It depends on which grade your water filter is.The advanced water filters contain instructions for direct drinking
Q:The difference between a faucet on a purifier and an ordinary faucet
Water purifier faucet, on the one hand is relatively small flow, and ordinary bibcock is different; on the other hand, material requirements are higher, requirements are lead-free. However, the market price of 100 yuan or so, the quality of the faucet is not good. The best choice of stainless steel products, lead-free guarantee.
Q:Is the water filter air cleaner better than the filter screen?
2). Electrostatic is the use of electrostatic interaction, adsorption of pollutants in the air to the electrode, to purify the air. Compared with the filter purifier, the only advantage is not to replace the filter. However, electrostatic purifier machine of high cost, need regular cleaning electrode, is its disadvantages. Some electrostatic purifier with electromagnetic pollution very strong or release of ozone. Because to make high purification efficiency, must improve the voltage inside the machine. And the higher the voltage, the electromagnetic ozone pollution more severe. Of the contradiction.
Q:What are the major differences between backwash filters and self-cleaning filters?
Self cleaning filter is divided into several kinds: manual self-cleaning filter, self-cleaning filter (with motor)Disc type automatic filter is also called self-cleaning filterSelect the relative adaptation filter according to different requirements
Q:The difference between a water purifier and a filter
Water purifier is also called water purifier, water filter, the core of its technology is the filter membrane in the filter core device. The main technology of water purifier is derived from two kinds of ultrafiltration membrane and RO reverse osmosis membrane
Q:What do you use to make your own drinking water?
2, take an empty plastic bottle, cut off the bottom of the bottle with the single hole plug plugged with a catheter, the bottle, the bottle from the bottom to the top layer placed washed loose cotton, gauze, activated carbon (i.e., charcoal), quartz sand, pebbles, get a simple water purifier the. Can also put a layer of quartz sand and activated carbon in below.
Q:How can I buy the chemical nickel filter without pumping water?
If the dosing barrel is flooded, switch off the dosing bucket valve. The landlord must have bought the inferior filter
Q:Is it necessary to install household tap water purifier?
I understand that this is the case, the mother-in-law bought a more than 600, three months to wash once, as if to call someone to wash, money. Three years later to change the core. One of them needs more than 1000. After 500 tons of water, it will be destroyed.
Q:Does anyone know why the water purifier uses the pre filter system?
Stage 1: micro filtration membrane: removal of various visible matter / dust and impurities in tap water by microfiltration. These particulate matter comes from pipe aging, rusting, roof water tanks, two pollution, and so on.Grade second: compressed carbon: compressed carbon to remove chlorine and organic impurities, such as harmful pesticides. It also absorbs odors, colors, and odors produced by organic compounds in water, which are derived from tap water disinfection by-products.
Q:What's the difference between a backwash filter and a self-cleaning filter? What about the two?
Automatic cleaning procedures are usually triggered according to the use time, and the general cleaning methods are backwash
