Hansbell pre filter is not good

The pre-filter is to protect the water purifier, and the most important thing is to see whether the filter element is good or not.

First, the purchase of pre-filter should choose a more well-known brand, some manufacturers have the production and technology of pre-filter before the rise of household pre-filter, such as solar energy manufacturers and well-known water pipe fittings manufacturers.

The second is function, you can choose a filter with pressure stabilization to ensure its backwashing function and the normal use of household tap water.

Third, it should be installed on the outlet side of the main valve of the household water inlet during installation, so as to facilitate later maintenance and maintenance. If the original main valve at home is insufficient, it can be installed at the tube well water meter.

Fourth, after a period of use, the impurities in the filter tank should be released through the small valve below, usually in the use of half a month to a month, and the interval can also be appropriately adjusted according to the water quality in different places. After half a year to one year of use, the filter tank can be unscrewed and the filter screen can be taken out for flushing. The pre-filter does not require the filter to be replaced.

How do I choose a pre-filter?

When selecting a pre-filter, we should generally look at the following points.

1. Choose excellent manufacturers.

Good manufacturers, their products will naturally not be bad, secondly, the reputation of the powerful manufacturers are also more secure.

2. Look at the pressure-bearing capacity.

Unstable water pressure is easy to cause damage to the equipment, so there are also high requirements for the pressure bearing capacity of the equipment.

3. Look at the filter material.

The material of the filter is related to the service life, generally speaking, the stainless steel filter is more strong and durable, while the nylon one is easy to deform.

4. Look at the backwash effect.

The pre-filter needs to be backwashed every once in a period of time to remove impurities on the filter screen, and the backwashing effect is good to ensure that the equipment is in a better working condition.

Does the pre-filter work when it is installed in the water pipe? Today is a long time to see.

Pros:

1. The product structure is compact and lightweight, the filtration accuracy is clear, and the flow rate is large.

2. It can be used for sewage dischargeThe filter element has a long service life and failure rate.

Low. 3. It can protect downstream equipmentFor example, the high-grade faucet is not clogged, and the water heater tank has less sediment.

Cons:

Only impurities greater than the set filtration accuracy can be filtered. Similar to yellow water.

Black water, odorous water, alkali, scale and heavy metals cannot be removed because the filtration principle of screening has little effect on the water pressure of the pipeline.

Pre-filter.

It is the first coarse filtration equipment for the whole house water, which can filter sediment, rust and insect eggs in tap water. Bloodworms and other large particulate matter. The pre-filter is generally installed at the front end of the pipeline, so it is named after the word "pre-filter"; "Filtration", on the other hand, refers to the basic principles of such equipment.

The main function of the household pre-filter (Lanzer L-10PA L-10PB L-30PA L-30PB L-30PC) is to filter out large particles of impurities that are generally visible to the naked eye, such as sediment, rust, bloodworms and other substances.

The advantages of the front are as follows:

1. The product structure is small and lightweight, with clear filtration accuracy) large flow rate;

2. It can be drained, the filter element has a long service life and low failure rate.

3. It can protect downstream equipment, such as high-grade faucets without clogging, water heater liner with less sediment, etc.

The disadvantage is that the function is limited, and only the impurities that are greater than the set filtration accuracy can be filtered, such as yellow water, black water, odor water, water alkali, scale, and heavy metals can not be removed, because the filtration principle of screening is adopted, which has a slight impact on the water pressure of the pipeline tap water.

The pre-filter is generally made of stainless steel, which mainly filters large particles of impurities. Lanzer Canada uses a 40-70 micron medical-grade precision stainless steel filter. The core advantage is that there is no need to replace the filter element for life, and only the filter needs to be flushed regularly.

Advantages of the pre-filter:1.The filtration accuracy is high, and the pore size of the filter element is uniform.

2. Small filtration resistance, large flux and strong sewage interception ability.

3. The filter element material has high cleanliness and no pollution to the filter medium.

4. Resistant to acids, alkalis and other solvents.

5. High strength, high temperature resistance, and the filter element is not easy to deform.

6. Low operating cost, easy to clean, and the filter element can be replaced.

Disadvantages of the pre-filter:1.Only substances larger than the pore size of the filter element can be filtered, and some substances cannot be removed;

2.Filters need to be replaced frequently.

Have a lot of dirty stuff as soon as the faucet at home is turned on? Did you forget to install a pre-filter when you renovated your home? Maybe many friends don't know what a pre-filter is.

What is the use of it, in fact, the pre-filter is like installing a safety guard in front of the water inlet of your house, what sediment, rust, and some messy algae can be blocked out of your water pipe, spend a few hundred yuan to have one more helper to remove impurities from the tap water, do you say? At present, the mainstream pre-filter on the market has an hourly water output of about 3 tons, and the accuracy is about 40 microns, many people may have no concept of this data, let's talk about the water output first, the general household kitchen water, the water output of the faucet is about 5 to 8 liters per minute, the shower used for bathing is about 8 to 10 liters per minute, and the water output of 3 tons per hour can basically be used by three faucets at the same time, that is to say, you are completely fine with washing clothes in the washing machine while taking a bath. The concept of 40 microns is better understood, the diameter of a hair is about 60 to 90 microns, that is to say, the pre-filter can filter out impurities half the size of the hair, isn't it very effective?

Of course, the pre-filter is best installed together during hydropower construction, otherwise it will be very troublesome to install it later, and like all filtration devices, the pre-filter also needs to be opened regularly to clean the filter screen, otherwise the water output will become smaller in the later stage, and the water quality will also be affected.

Advantages: Protect the wading equipment and pipes in the home, such as all faucets, water pipes, water heaters, etc.; The upfront investment is low, the post-maintenance cost is almost zero, and most families can buy it.

Disadvantages: Coarse filtration, limited by filtration accuracy, unable to filter bacteria, viruses, heavy metals and other harmful substances, can not achieve the effect of direct drinking.

Is it okay for the pre-filter to be installed in front of the valve at home.

Wanshirong high-end pre-filter China operation center: the advantages do not need to be repeated, it is the first protective wall of household water protection, it is indispensable, we focus on the shortcomings of this awareness for your reference:

Industry disadvantages:1It cannot be confused with the water purifier, the pre-filter is to protect the water of the whole house, such as cooking, washing vegetables, bathing, washing clothes and washing dishes, the water purifier is only for drinking water (directly drunk) water purification requirements are higher, and the later cost is greater.

2.Cannot filter bleaching powder, odorous water, etc.

Other brand defects (Wan Shirong brand does not exist): 1The filter cleaning needs to be disassembled, and there is no disassembly for our disassembly-free cleaning.

2.Not frost resistant. Especially in the case of northern winter and some areas that need to be installed outdoors, it will freeze and crack in winter, our products are resistant to -30° low temperature, most products are resistant to -50° low temperature, and they are guaranteed for 10 years, so please rest assured about this.

3.Scientific experimental data verify that the filter accuracy of 40 microns is regarded as the best, greater than 40 The filtration effect is poor, higher than 40 affects the water pressure and water flow (the water flow will become smaller), and the accuracy of the Wanshirong filter screen is 40 microns.

4.The machine and material are uneven, resulting in the low-end of the product quality is very low-end, the high-end is very high-end, Wanshirong mainly does high-end pre-filter, after all, it is directly linked to the health of drinking water, and can not be ignored and neglected.

5.There is no brush, the cleaning is inconvenient or not thorough, it will cause blockage, Wanshirong pre-filter is a patented product, the first in the country, the brush cleans, national brand, exported to Germany.

The filter element of the air filter is generally replaced after about 3000 hours of use. However, it depends on the actual working conditions. Some of them have a shorter period of use.

Enmate, Aihuipu, 3M, mainly these imports are better, the domestic standard is lower than the imported ones, the theoretical life of use is 30 years, generally there will be a warranty during the warranty period, but more than the warranty period will need to pay for maintenance, but the general operation is normal and there is no excessive behavior to cause damage to the filter, the life will be very.

Introduction: Pre-filters are usually of a "T" structure. The left and right ends of the "one horizontal" position above are respectively the water inlet and outlet. The lower "vertical" position is the body and the internal cylindrical filter, and the bottom is the sewage outlet, which is controlled by a valve to open and close.

It mainly removes the precipitated impurities and bacteria, microbial debris, rust, sand and mud and other particle impurities larger than 5 microns generated by the pipeline to avoid damage to the human body and skin; And the downstream pipeline, water purifier, water heater, washing machine, high-end faucet, shower play a positive role in protection, the pre-filter can also add "hydrochloric acid phosphorus" scale inhibitor filter element to solar energy, water boiler to play a role in scale inhibition.

The life of the general pre-filter will not be too short, the use of the German Tejen AS16 pre-filter, when I bought the customer service seems to say that it is 70 years, whether it can be achieved or not, leave it to time, and follow up to observe and observe.

The pre-filter mainly relies on the built-in ultra-precision filter screen to filter out large particles such as sediment and rust in the water pipe. The filter for pre-filtration is not a consumable and does not need to be replaced regularly.

In daily use, it is necessary to open the sewage outlet regularly according to the different water quality and water consumption of the family to discharge the impurities filtered inside. Turn on the backwash function every month to flush and maintain the pre-filter.

Theoretically, the pre-filter has no service life, but in the process of use, due to the lack of daily maintenance, product aging may affect the service life. The home pre-filter can be used for 15-20 years, and if it is well maintained, it can also extend the service life.

The pre-filter is generally a disposable thing, and the kind with particularly good quality can be used for about 15 to 25 years, as long as the pre-filter is thoroughly rinsed many times, but most of the cleaning is not very clean, and the life is still average.

The pre-filter is the first coarse filtration equipment for the whole house water, which can filter large particles such as sediment and rust in tap water. The pre-filter is generally installed at the front end of the pipeline, so it is named after the word "pre-filter"; "Filtration", on the other hand, refers to the basic principles of such equipment.

Imports are better, domestic ones are worse than imported ones, and the theoretical life of use is 20-30 years, and the normal life of operation will be a little longer.

Depending on the product model, the service life is 5-20 years. There is no need to replace the filter element, open the sewage outlet once a week, and after the impurities are discharged, the sewage outlet can be closed and flushed with water once a month.

Read the manual! There are also models.

Choose big brands, such as the United States 3m, these big brands of pre-filtration are better, the standards are relatively high, and it is more reassuring to use, but at the same time, it will be relatively high. However, you can still get a lot of discounts if you choose the right place! For example, there is a ** in Beijing that will be called easy installation, where the 3m water purification will be hundreds cheaper than the activities in the store**, and you can also enjoy after-sales and service in the store, which is quite affordable, and only when you use this thing will you know how much it will improve the quality of life.
