Conventional whole house water filtration system rarely have a negative impact on household water pressure, regardless of whether the correct model is chosen, because they have larger filter pores and lower filtration precision. Consequently, when they used as whole house water filtration systems, their low filtration precision makes it difficult to achieve users’ expected filtering results.
Whole house water filtration system, also known as a whole hosue water pre-filter, is the first stage of filtration for the entire household water supply. Its purpose is to filter out impurities such as sediment, mud, rust, and colloids in the water, making the water entering household pipe branches cleaner, improving bathing water quality, preventing shower nozzles from clogging, and keeping laundry from yellowing.
But traditional steel mesh pre-filters have a maximum filtration precision of only 40μm, which only intercepts large sediment particles. They are virtually ineffective against fine impurities like mud, rust, and colloids. For this reason, mesh pre-filters have no market in rural areas, where turbid well water, mountain spring water, and stream water contain not only large particles but also large amounts of fine mud and colloids. Turbid well water that has passed through a mesh pre-filter remains turbid, leaving customers feeling that the product has no effect. Therefore, traditional whole house water pre-filters have no market for rural natural water and mountain spring water.
The same applies to PP cotton, a product familiar to many urban customers. Its filtration effect on fine impurities such as mud, rust, and colloids is also extremely limited, even with a higher precision, and its maintenance is very troublesome. PP cotton cartridges require frequent replacement; otherwise, bacteria levels can easily exceed standards. As sediment and other impurities trapped inside PP cotton accumulate continuously, bacteria multiply at an accelerated rate, turning the PP cotton into a breeding ground for bacteria. With a filtration precision of only 5μm, PP cotton cannot intercept bacteria, viruses, colloids, or fine mud particles. Once PP cotton reaches adsorption saturation, rapidly breeding bacteria, viruses, and fine impurities will pass through it and flow to the end water outlets, causing bacterial contamination in household water.
This is also why ChengrongEra do not recommend using activated carbon for whole house water filtration. Activated carbon would adsorb residual chlorine in water. Yet maintaining adequate residual chlorine is essential to prevent bacterial growth during water transportation and storage. Without residual chlorine, large amounts of bacteria and viruses can easily breed inside household pipes.
The most effective whole house water filtration system that truly fulfills whole-house filtration effect is ultrafiltration water filter. Nowadays, more and more users have realized this.
First of all, ultrafiltration water filters feature high filtration precision of at least 0.1μm, 400 times that of traditional pre-filters. Only ultrafiltration water filter can thoroughly intercept sediment, rust, colloids, and other impurities in water, achieving genuine whole house water purification, rather than merely being called a whole house water fflter because it is installed on the main water inlet pipe.
A netizen once told me that the ultrafiltration water filter installed in his home significantly has reduced water pressure, by an estimated 30% to 40% compared to the original tap water, resulting in very poor water usage experience.
I told him that this issue would not occur if he chose ChengrongEra ultrafiltration water filter for whole house water filtration system. Our whole-house water filtration system do not affect water pressure, because we recommend models based on each household’s actual daily water consumption, rather than luring customers into placing orders with low prices for the sake of sales. The user experience of a whole-house water filtration system depends on manufacturing quality, product functions, and structural design — not low prices. A cheap whole-house water filtration system offers no user experience and only causes frustration for customers.
ChengrongEra is not an isolated brand, ChengrongEra is a professional full-supply-chain manufacturer of ultrafiltration membranes and ultrafiltration water filters, ranking among the top three in the industry. We will never allow customers to experience a 30% to 40% drop in water pressure after installing ChengrongEra ultrafiltration water filter.
Despite its high filtration precision of 0.1μm, ChengrongEra whole-house water filtration system do not reduce household water pressure. Drawing on 19 years of industry experience, I have developed two Chengrong Formulas, which allow customers to calculate the suitable membrane flux specification for their homes. As is known, the larger the membrane flux of an ultrafiltration water purifier, the smaller the impact on water pressure — but the higher the cost. This Chengrong Formulas strike a balance between customers’ economic costs, water usage experience, and service life, a feat rarely matched by any other company in the industry.
