The filter element of water purifier is the most worrying thing for buyers. The good and bad of intelligent water purifier are related to the filter element, which also affects the cost of replacing the filter element later. To put it bluntly, just like the core components of a smart phone, how powerful the core components are, how powerful the smart phone is. So for this water purifier filter element, the following small series of water purifier filter element common sense, hope to help you.

The common filter elements of water purifier on the market are as follows and their replacement cycle

1、 PP cotton filter element

The tubular filter element made of non-toxic and odorless polypropylene particles can remove the impurities such as sediment, rust, colloid and insect eggs in water. It is usually used as the first stage filter element of water purifier, and the replacement cycle is 2 to 4 months.

2、 Activated carbon filter

It is divided into granular activated carbon filter, compressed activated carbon filter and sintered activated carbon filter. The innermost layer of the filter element is polypropylene skeleton, which is covered with multi-layer polypropylene superfine fiber. The surface density is low, and the replacement cycle is generally 6 to 8 months.

3、 Hollow fiber ultrafiltration membrane

The hollow fiber tube is full of micropores. Macromolecular substances in water can be filtered by external pressure or internal pressure. It can filter suspended solids, particles, colloids, viruses, bacteria and other harmful substances. The replacement cycle is 12 to 24 months.

4、 RO reverse osmosis membrane

The pore size of reverse osmosis membrane is 0.0001 μ M. under certain pressure, water molecules can pass through, while dissolved salts, colloids, organics, heavy metals, bacteria, viruses and other substances in water will be intercepted. The replacement cycle is 12 to 24 months.

5、 Post activated carbon filter

It is also made of activated carbon. As the final filter element, it can further remove odor and residual chlorine, inhibit bacteria, prevent secondary pollution of purified water, improve the taste of purified water, and make purified water taste better. The replacement cycle is also 6 to 8 months.

Installation method of filter element of water purifier

1. Close the inlet tee and pressure barrel ball valve, turn on the clean tap, and let the outlet drain the residual water in the machine for about 10 minutes;

2. Turn off the power, pull out the power cord and wait for the machine to stop; Pull out the tap water pipe, pressure bucket water pipe and waste water pipe in turn;

3. Take out the water purifier, put it flat on the table, open the cover of the water purifier, and see the position of the filter element clearly;

4. Use a special wrench to open the filter barrel cover in turn. After opening, take out the old filter element in turn and replace it with a new one (RO membrane needs to be pulled out with inclined nose pliers); After the replacement, connect the water pipe, if there is a blocking card, remember to insert the blocking card, and then tighten the filter barrel cover Then cover the upper cover, return the water machine, plug in the water pipe and power supply, and turn on the water inlet tee;

5. Wait about 20 seconds, after the air is discharged, turn on the faucet, and let it drain for 10 minutes. First, activate the filter element to ensure the filtration function and prolong the service life. Second, a small amount of activated carbon powder may rush out, leading to dark color water waiting for it to flow out;
