You really choose the right? Household water purifier full science, the original variety so much!

Recently around a lot of friends are talking about water purifiers, everyone's discussion of the heat of a higher than a high, talking about drinking water health, as if it has become a daily topic that every family can not avoid. Especially now, we are more and more concerned about the safety of drinking water, no matter how clean the home tap water looks, there will always be people worried about ‘secondary pollution’, ‘heavy metal residues’ and "odour impurities ". Thus, the water purifier has become a new favourite in the eyes of many people, but in the face of a row of different brands, different functions of water purification equipment, you are not often caught in a tangle - in the end, what kinds of suitable for our ordinary families? And how to choose will not step on mine?

In fact, the market is really quite a lot of types of water purifiers, some are hanging on the wall is small and delicate, there are large head placed under the cabinet, there are also directly connected to the countertop seems particularly convenient. These products are not only different in appearance, the core technology behind them, filtration methods and use scenarios are also very different. So the question is, in the end, what are the mainstream categories? What are their respective characteristics? And how to make a choice according to the actual situation of your home?

Speaking of the most common types, have to mention ultrafiltration, reverse osmosis (RO), activated carbon and the four main protagonists of pre-filtration. Many people are easily confused, thinking that as long as the dirt can be stopped on the end, in fact, each technology for the problem point is different. For example, activated carbon filter mainly by adsorption, can help you remove the residual chlorine in the tap water, odour and some organic matter, if your home floor is high, low water pressure, this small volume design just come in handy, and replace the cartridge is also quite convenient. However, it should be noted that the ability of this type of equipment to remove bacteria, viruses or heavy metals and other small impurities is still limited, so if the drinking standard requirements are higher, it needs to be further upgraded.

To say that now the most hot, by countless businessmen advertise the one, it must be non-reverse osmosis (RO). These products use a layer of very fine film, through the external pressure so that the molecular level of small particles in order to pass, most of the bacteria, viruses and even heavy metal ions will be firmly blocked out. It can be said that as long as the installation of a RO machine, tap water to drink and bottled mineral water flat not much difference. But the same because the filtration is extremely thorough, so out of the pure water almost no minerals, relatively light taste; In addition, it will produce a certain percentage of waste water, and the installation of space, water pressure are some requirements.

A friend asked: what about ultrafiltration membrane? In fact, ultra-filtration belongs to a programme between activated carbon and RO, it uses more than a few dozen times finer than a hairline tubular membrane, the sand and rust, colloidal impurities isolated very clean, while still retaining a portion of the natural mineral composition, both to ensure basic safety, but also will not make the taste bland. If you usually like to drink boiled tap water directly but are worried about limescale, this product is definitely worth considering.

In addition to the kitchen terminal, there is a small thing called pre-filter is often overlooked, but in fact the role is very important. It is usually installed in the home next to the main valve, responsible for the initial interception of rust, large particles of impurities and sediment, equivalent to all subsequent water equipment to do a basic protection. Not only can extend the life of the downstream water heater and washing machine, but also reduce the burden of the rear filter. If possible, it is recommended to install a pre-filter, and then select the kitchen or whole-house type terminal equipment according to the needs of the two with double the effect.

Warm tips: when selecting, please be sure to pay attention to the following points -

【1】to understand the local tap water usually test report, to see if there is no residual chlorine taste heavy or heavy metals exceeding such a problem;

【2】 to estimate the number of people in the house and the daily amount of small capacity desktop machine suitable for a single person or a two-person family, the large household is recommended to consider the flow of larger Central type;

【3】 Do not forget to consider the size of the kitchen space, because the embedded and desktop size difference is quite large, sometimes a machine looks beautiful to the cooker under the stove but how can not be stuffed into;

【4】 Regular replacement of cartridges is very critical, otherwise even the most advanced machines are just a decoration;

【5】 budget range can pay more attention to after-sales service, such as whether or not to install the core of the core reminder of the thoughtful features.

Some people may hesitate: ‘Is buying a water purifier too wasteful?’ or ‘Is there a “universal” model?’ In fact, every family's habits are completely different. If you are simply aiming to improve taste and make tea more aromatic, activated carbon or ultrafiltration is sufficient to meet your needs. If there are elderly or children in the household who place a high priority on health, reverse osmosis (RO) is naturally the top choice. However, do not neglect to regularly supplement with trace elements, such as calcium and magnesium, through dietary intake. Additionally, for those who prefer to drink cold, filtered water directly, high-end models often come with UV sterilisation or silver ion antibacterial modules, providing greater peace of mind, especially in humid regions like the south.

Speaking of which, you might also wonder: why is there such a significant price difference in the market? For example, even with the same five-stage filtration system, there are brand premiums and differences in the origin of core components, such as imported membranes, which are significantly more expensive but offer better performance and longevity. Moreover, reputable manufacturers typically provide detailed test reports and third-party certification certificates, which are important references for assessing product quality. Therefore, it is recommended to choose well-known brands with physical after-sales service centres when purchasing, as this is more convenient and avoids the awkward situation of no one taking responsibility for any future issues.

In summary, no single type is suitable for all households; individual needs ultimately determine the choice. If you prioritise ultimate purity and safety, reverse osmosis is the obvious choice. If you seek a balance between cost-effectiveness and basic protection, ultrafiltration or composite activated carbon systems are fully capable of meeting these needs. As for whole-house water softening or central treatment systems, these are more suitable for villas, custom-built homes, and large-sized residences that prioritise comprehensive living quality. With the popularisation of smart home concepts, many new products now offer APP remote monitoring, replacement reminders, and even voice interaction, making access to clean water more convenient and effortless.

Finally, a friendly reminder: regardless of the model, always inspect the packaging upon delivery to ensure all components are present, carefully read the manual, and install the system according to the environmental conditions. Avoid hiring unqualified workers for unauthorised modifications to prevent potential safety hazards. With a reliable, user-friendly water purification system backed by a dedicated maintenance service team, you can enjoy the peace of mind and sweet taste of clean water every time you turn on the tap!
