Many fans asked me to talk about the "Water filter". In this issue, Andy will summarize which Water filter are not worth investing in based on his own purchasing experience.

Before the opening, let's make it clear that this article will not discuss the topic of "Is it necessary to install Water filter?".Because from the perspective of water safety in the whole house, Water filter is valuable.

And, to be honest:There is no problem with the Water filter itself. The problem is that some poor manufacturers and businesses have broken the Water filter market

Things are good, but not all Water filter are worth investment.

As a standard Small appliance in the kitchen, the popularity of Water filter is getting higher and higher. However, it is not uncommon for users to make mistakes and waste money on it.

In the final analysis, it is because of the lack of understanding of Water filter.Andy summarized the "four no choice" principle of Water filterI hope it can provide some reference for everyone:

1. Water filter without general filter element is not recommended

What is a universal filter element?

Simply put, it meansThe "mainstream" filter specifications on the market include the "length", "diameter", and so on of the filter.As long as the manufacturer's Water filter does not use a universal filter element, I suggest that you should be careful to choose.

I have already stepped on the pit here.Because when the manufacturer produces their own "customized filter element", it means that when replacing the filter element in the future, they can only choose from the manufacturer.And the IQ tax becomes' no pay no pay '.

On the other hand, the Water filter using mainstream filter element will not be restricted by the manufacturer when the filter element needs to be replaced.From the point of view of the cost of consumables, choosing a Water filter with a universal filter element in the market would save money.

Due to the mainstream specifications of filter cartridges on the market, the cost is very low.Taking PP cotton filter cartridge as an example, the market cost is only 20-30 yuan.If the filter element is customized by the manufacturer, its price is "completely independent".It also means that users will "overpay".

2. Water filter with RO reverse osmosis membrane filter element only, not recommended

When purchasing Water filter, I believe many people have found that many Water filter from manufacturers have strong purification effects, including both coarse filtration, activated carbon adsorption, and RO reverse osmosis membrane.

It is undeniable that,The filtration accuracy of RO reverse osmosis membrane is indeed the highest, and the filtered water is indeed "pure". However, Andy does not recommend that you choose a Water filter with "only" RO reverse osmosis membrane filter element.

Because the water filtered out by RO reverse osmosis membrane is truly "pure water".To what extent is' pure '?

Not only have impurities and heavy metals been filtered out,It also filters out the "mineral elements".This is also the main reason why many manufacturers say that the water from the RO membrane can be directly consumed.

It is undeniable that,This is also the fundamental reason why Andy said that only RO membrane Water filter is not recommended.

3. Water filter with short filter element replacement cycle is not recommended

As I mentioned above, Water filter itself is a good thing, but manufacturers and businesses have done a bad job in the market.

This can be seen from the "filter replacement cycle".Many manufacturers intentionally guide users to frequently replace filter elements, in other words, they want to continue to make users pay.

From another perspective,Behind the frequent replacement cycles of the filter element, there may also be a factor of poor material quality, which greatly shortens the service life of the filter element.(Taking RO reverse osmosis membrane as an example, the replacement cycle for low-end products is 1-2 years, and high-end products can even reach 5 years.)

So from the perspective of filter element replacement cycle, if you choose a Water filter, you must ask about the replacement time of various filter elements. Avoid duplicate payments due to filter cartridges.

Moreover, replacing the filter element too frequently is also troublesome and affects the home life experience.

4. Water filter that is too expensive

In fact, before my home appliance evaluation, I had invested more than 10000 yuan in Water filter.The last time was to replace a Water filter worth more than 3000 yuan with a Water filter worth only a few hundred yuan.

Many people may not understand. Why choose the lower priced one?

Only those who have come to know that Water filter has developed for so many years, but there are not many breakthroughs in technology. In the final analysis, the filter element plays a leading role.So choosing the right filter element is enough.

For the Water filter that is too expensive, it must be acknowledged that the quality of workmanship may be better, but the purification effect is the same when the filter element configuration is the same.A considerable part of the reason for the high price is actually due to the brand premium.

This is also the main reason why large brands are priced at two to three thousand yuan, or even six to seven thousand yuan. After all, big brands need marketing and image building.

If the four Water filter mentioned above are not selected, how should they be selected?Andy briefly summarized four points, which you can learn from:

(The water efficiency level of the Water filter is similar to the energy efficiency level of household appliances. The higher the level, the better the water purification effect and water purification flux.)

(The purification precision of ultrafiltration membrane is only inferior to RO reverse osmosis membrane, and the former will not filter out mineral elements)

(Determined the later usage cost)

(There's no need to invest too much, first identify the filter element, then consider the brand)
