I used to think that the tap water used at home was very clean, until I used a bucket to catch the water after the water stopped, and I realized that I was wrong!
Then I started my road of buying, buying, buying, and installing 3 of them (of course, all of them are not very complicated pipes), and summarized the following experience.
For water purifiers, my personal opinion is: there are 4 kinds not to install, and 5 types to buy. This is by no means misleading, but a lesson learned from the exchange of 3 units.
One:4 do not buy
1. Do not buy water purifiers with non-universal filter elements
Some brands of water purifiers, in order to pursue so-called "exclusive technology" or "high performance", will use non-generic filter cartridges. These filters tend to be expensive and inconvenient to replace. Once the brand stops producing this filter, or raises the price, consumers are left on the back burner.
Suggestion: Prefer to choose a water purifier that uses a universal filter cartridge, which is not only easy to replace, but also relatively transparent in price.
2. Do not buy water purifiers with non-RO reverse osmosis membranes
At present, the mainstream water purifier technologies on the market include ultrafiltration, nanofiltration and reverse osmosis, among which the filtration effect of RO reverse osmosis membrane is the best. It can effectively remove bacteria, viruses, heavy metals and other harmful substances in the water, and ensure the safety of the effluent. Those water purifiers with non-RO reverse osmosis membranes, although the price may be cheaper, but the filtration effect is greatly reduced.
Suggestion: From the perspective of long-term use, choose a water purifier with RO reverse osmosis membrane.
3. Don't buy a water purifier with too complicated functions
In order to attract consumers, some water purifier brands will add some fancy features to their products, such as intelligent networking, APP control, etc. These features are not practical for the average home, but will increase the failure rate and repair costs of the product.
Tip: Focus on the core indicators such as filtration effectiveness and water discharge speed, and don't be fooled by those flashy features.
4. Don't buy water purifiers with inflated prices
The water purifier market is mixed, and the price is also very different. Some brands will set the price of their products very high in order to pursue high profits, but in reality, the performance and quality of the products are not outstanding.
Suggestion: Shop around, don't be fooled by the merchant's publicity, and choose cost-effective products is a wise move.
Two: 5 buy
1. Buy a water purifier with a fast water delivery speed
Water discharge speed is one of the important indicators to measure the performance of water purifiers. If the water is too slow, it will not only affect the user experience, but also cause a waste of water resources.
Recommendation: Preference is given to products with fast water dispensing speed. Generally speaking, a water purifier with a water discharge speed of more than 1L/min can meet the needs of most families.
2. Buy a water purifier with a low wastewater ratio
The wastewater ratio refers to the ratio of wastewater to pure water produced by the water purifier in the process of water production. The lower the wastewater ratio, the higher the water production efficiency of the water purifier and the higher the water resource utilization rate.
Suggestion: When purchasing, pay attention to the wastewater ratio index of the product, and give preference to products with low wastewater ratio. Generally speaking, a water purifier with a wastewater ratio of less than 1:1 can be considered to be more water-saving.
3. Buy a water purifier with zero stale water function
After many water purifiers are not used for a long time, the first glass of water will have the problem of too high TDS value, and they need to be put away before drinking. The water purifier with the function of zero stale water can solve this problem well. It can automatically flush and replace the water purifier when it is not in use for a long time, ensuring that the TDS value of the first cup of water also meets the standard, thus avoiding the waste of water resources.
Recommendation: Prioritize products with zero stale water function.
4. Buy a water purifier with a large rated water purification
The rated water purification refers to the maximum amount of water that the water purifier can handle during the life of the filter element. The higher the rated water supply, the longer the service life of the filter element and the lower the frequency of replacement
Suggestion: Pay attention to the rated water index of the product, and give priority to the product with large rated water purity. This not only reduces the frequency and cost of replacing the filter cartridge, but also ensures the stability and safety of the effluent.
5. Buy a water purifier with good after-sales service
As a long-term home appliance product, the quality of after-sales service directly affects the user's experience.
Suggestion: In addition to paying attention to the performance and price of the product, it is also necessary to focus on the after-sales service of the brand. Priority is given to those brands and products that provide door-to-door installation, free maintenance and other services, so that they can be better guaranteed and supported during use.
summary
Buying a water purifier is not a simple matter. We need to consider various factors according to our actual needs and budget in order to choose a high-quality product that is truly suitable for us.
