What brand is good to buy for pre-filter? Top 10 best-selling brands in 2024

In today's ever-changing market, it is important to choose a pre-filter that is both affordable and of high quality. The pre-filter is the first line of defense for household water, which can not only intercept large and small particle impurities such as sediment, insect eggs, rust, etc., kill pollution at the source, but also extend the service life of wading appliances at home, so it is recommended that every family has to install it, and its practicality and versatility are very important. However, in the face of many brands and models, it is often difficult for consumers to choose, this article will not only recommend cost-effective high-quality pre-filter brands for you, but also analyze the purchase skills of pre-filters in detail to help you make a wise choice.

Pre-filter buying tips:

1. Gimbal Installation:

It can avoid problems such as transforming pipes and interfaces, and do not pick the installation environment.

2. Effluent flow:

The flow rate of the pre-filter, also known as the flux, is a key indicator that affects the water pressure and water volume. The general flow rate is 6t/h, which does not affect the water pressure and meets the peak time of water consumption, which can be used as a reference.

3. Flushing system:

The flushing method is mainly divided into three ways: positive flushing, siphoning and backwashing, and from the perspective of cleaning effect, backwashing is better than siphon flushing and positive flushing. Of course, there are a variety of flushing methods for mid-to-high-end pre-filters, such as turbine or cyclone type.

4. Material:

The copper head with lead isolation technology is the best to avoid secondary pollution; The filter screen is made of 316L stainless steel for the best filtration performance; The filter bottle is BPA-free, explosion-proof and freeze-resistant.

5. Filtration accuracy:

At present, the mainstream accuracy range of the market is 40-60um, and it is more reasonable to choose 40 microns, which can effectively intercept impurities and will not easily cause blockage, and the filtration effect is good, and the higher specification is 30 microns, and the effect will be stronger.

6. Other accessories:

Intelligent automatic flushing mode, precise water pressure gauge, monthly dial, the higher the configuration, the stronger the practicality, and of course, the more expensive the price.
