Is the pre-filter useful, is it necessary to install it? What are the best pre-filters with good reputation? There are many friends who have never bought a pre-filter, and they have such questions before purchasing. After reading this article, you will know how to choose, and you will use your own experience to present it to you.
1. Is it necessary to install the pre-filter?
Pre-filters are very useful and necessary to be installed, generally at the point where the water pipe enters the house.
As a household water purification device, the pre-filter can effectively filter large particles of impurities, such as sand, soil, chlorine, iron, rust, scale and large particle pollutants in the water, which will affect the taste, quality and cleanliness of the water, and with the pre-filter can ensure the cleanliness and safety of the water quality.
Reason 1: Protect household water safety
No matter how clean the tap water is, if you look closely, you will see that it contains visible sediment, sediment and metallic substances, including some bacteria. This kind of water is unhealthy, and if you drink it regularly, it will cause gastrointestinal dysfunction and diarrhea. Choose a high-quality brand of pre-filter, its water purification effect is remarkable, can effectively filter out all kinds of harmful substances in the water quality, play a good water purification effect, so as to ensure everyone's healthy water quality needs.
Reason 2: Protect the life of household appliances and prolong the life, cost-effective
If there is no pre-filter to intercept some large particulate impurities, pollutants can easily cause damage from the inside.
As a simple example, our shower showers often block or have thick dirt after a period of time, because the sediment is directly blocked from the inside, and the dirt is affected by the water quality of heavy metals.
Therefore, there is a pre-filter to protect wading appliances and effectively extend the service life, which is obviously cost-effective.
Through the above introduction, we know that the front water purifier is indeed useful and necessary to install. However, it should be noted that it serves as a basic filtration, and the filtered water does not meet the standard of being ready for drinking.
2. What is the pre-filter purchase guide?
- Filtration accuracy: At present, the mainstream accuracy range of the market is 40-60um, and it is more reasonable to choose 40 microns, and the larger particles will be intercepted, and the filtration effect is good, and it will not be easy to cause blockage, resulting in smaller water pressure and inconvenient water use.
- Flow: The flow rate of the pre-filter, also known as flux, is a key indicator that affects water pressure and water volume. Usually, the labeled flow rate of the product is mostly 3-6 tons/hour (t/h), and it is recommended to buy a large flow rate of 6t/h
- Flushing system: The flushing method is mainly divided into three ways: positive flushing, siphoning and backwashing. The mid-to-high-end pre-filter has multiple flushing methods, and the effect is even better.
- Material: stainless steel filter screen + lead-free copper nozzle + polymer explosion-proof filter bottle
3. What are the best pre-filters with good reputation?
1、BKA 前置过滤器 任意装-S10W PRO
I bought this BKA-S10W PRO, what I liked was that its universal installation direction can be adjusted 360° arbitrarily, I often see people on the Internet say that the installation of the pre-filter can not be used after buying, and the need to transform the channel or change the interface and other problems, the cost is higher, but there is no need to worry about this problem if there is a universal installation.
Universal installation: 360° universal valve interface, suitable for various types of water pipes, sturdy and durable, not to pick the installation environment; No matter how it is installed, the fuselage will always remain vertical after installation, and the gravity effect can achieve more thorough cleaning and blowdown, reducing clogging and reducing the risk of water leakage.
And the high-quality workmanship, the materials used are very sincere. Not only the valve head uses environmentally friendly copper, but also uses lead isolation technology and adds antibacterial technology to avoid secondary pollution of water sources and ensure water quality; In addition, the bottle body has the functions of explosion-proof, shock-proof and anti-freezing, and the safety is very good.
Outstanding flushing effect: It is worth affirming that the upgraded Pro model of BKA has multiple "drive modes". The combination of the three-turbine water-driven double-siphon backwash mode and the double-sided three-axis brush cleaning will form a similar brush to wash it with turbulence, and the sewage discharge performance of cleaning from the inside to the outside is more excellent, and a double-spiral screw channel is formed during flushing, which can effectively remove impurities in the filter screen; Drive the double-sided three-axis brush to achieve all-round cleaning of the filter screen and filter bottle. This self-cleaning mode not only improves the flushing efficiency, but also increases the effectiveness and patency of the blowdown.
High flux flow rate: There are many situations where water is used simultaneously in multiple places such as bathrooms and kitchens in the home, so it is extremely necessary to install a pre-filter with a large flow rate. This pre-filter has a maximum water purification flow rate of 6T/h and a high filtration flow rate, so there is no need to worry about water pressure, thus ensuring everyone's overall water demand.
High filtration effect: the filter screen is a 316L medical food grade filter, the filtration accuracy is 40 microns in line with the mainstream of the market, and the interception rate is as high as 98.2%, which intercepts impurities in the water to a greater extent and is not easy to block, and the filtered water can clean vegetables and fruits, and the health and hygiene are quite good.
Overall, this BKA-S10W PRO pre-filter has a good configuration and outstanding comprehensive performance; There is also a high-end water pressure detection meter, which is convenient to grasp the real-time water pressure situation, and the current use experience is good, and there are almost no shortcomings.
In addition, after the previous research, there are several good pre-filters, which can also be referred to.
2、霍尼韦尔 前置过滤器 PFF91T12-EC
The same flow rate is 6T/h, the filtration accuracy is 40 microns, and the rejection rate is as high as 98.9%, which is very thorough in the filtration of impurities. The more prominent highlight is that the screen adopts a digital touch screen, with four options: 7 days, 15 days, 30 days and immediate flushing.
Consumers can choose different cleaning time intervals according to their own water conditions, and they can rinse immediately with just one button, which is easy to operate, saving time and effort. The flushing method is twin-turbo 360 backwash, which has a better cleaning effect than the previous siphon backwash.
3. Pentair pre-filter B140-B1104
B140-B1104 is one of the most classic and popular products of Pentair, with a 6T/H high-flux design, which can easily meet the water needs of the whole family.

Haier has demonstrated excellent quality in terms of materials and technology. In terms of material, the patented technology of double lead isolation is used to effectively prevent lead precipitation and ensure the safety of household water. The fine filtration accuracy of 40 microns can intercept a large amount of sediment without causing the problem of low water pressure in the clogging.
At the same time, the use of 316 stainless steel filter ensures the long-lasting and stable filtration effect. It is worth mentioning that the unique 360° twin-turbo rotary flushing backwash design can clean the interior in all directions without dead ends, effectively remove impurities and dirt, and ensure the purity of water quality. Moreover, the 7T ultra-large flux design far exceeds the flux of other filters and meets the water demand of the whole house.
