The filter element is changed once every six months?! But when you really inquire carefully, you realize that the way to replace the filter element in half a year is completely wrong.
In daily life, we decide when to replace the filter cartridge according to the prompts on the water purifier. Usually, these alerts will be sent out in about half a year to let us know that the filter needs to be replaced. As soon as we receive such an alert, we take immediate action to ensure that the filter is replaced in a timely manner. However, if the water purifier has not been used in half a year, does it mean that the filter element needs to be replaced in this half year?
In fact, the filter replacement prompt on the water purifier is mainly based on the time factor. As soon as the preset replacement interval has been reached, the machine will send a reminder. However, it is important to understand that the actual life of a filter does not depend solely on the elapsed time, the amount of water used has a more significant impact on its lifespan. Therefore, even if the water purifier has not been used for half a year, if it is replaced according to the regular replacement cycle, other factors such as the actual condition and usage of the filter element may still need to be considered.
There are two reasons for the correct filter change:
First: Understand the water purifier's water dispensing speed – In order to figure out the dispensing speed of your water purifier, you need to focus on one key parameter: flux. With a simple calculation formula, you can easily grasp the speed of water discharge. The formula is as follows: Velocity = Flux 24 60 379」▽
Imagine that if a water purifier has a flux of 1000g, then its water output speed will be an astonishing 26l/min。This means that a 500ml bottle of mineral water can be filled in just 12 seconds.
When the water purifier's water dispensing speed slows down to less than half the theoretical speed, it means it's time to replace the filter cartridge. In the case of the 500ml mineral water bottle, if it is not filled after 25 seconds, it means that it is time to change the filter.
Thirdly, if you want to know how effective the water purifier is at home, you only need to spend twenty or thirty yuan to buy a TDS pen to easily measure the ion concentration in the filtered water. When the ion concentration exceeds 10 milligrams per liter, this is no longer considered pure water; If it exceeds 50 milligrams per liter, such water is not suitable for direct drinking.
Typically, new cartridges reduce the ion concentration in the water to less than 5 milligrams per liter when first used. But over time, after a year and a half of use, ion concentrations are likely to rise to more than 10 milligrams per liter. If you don't have particularly high water quality requirements, there is no need to replace the filter cartridge immediately.
Only when the ion concentration of the purified water is close to 50 milligrams per liter should the filter cartridge be replaced. After all, instead of changing them frequently, you can let the filter do its best to keep your drinking water safe in your home.
When the body of the water purifier starts to sound the alarm, I understand that many water purifiers are only prompted by the indicator light, but the piercing alarm sound is really annoying. In order to be quiet, there are four ways to do this:
Press the "reset" button directly on the fuselage, and the eye-catching logo seems to beckon to me, as if to say: "Press me, and everything will be calm again." ”
Flip through the manual, find the two buttons hidden in the text, and press and hold these two buttons, as if pressing a pair of mysterious magic buttons, so that the water purifier can be reborn.
If that doesn't work, remove the filter and reinstall it. This process can be like a small home repair challenge that requires care and patience.
In addition, you can also operate it through the mobile app, touch the "reset" button, as if casting a magic on the mobile phone screen to quiet the water purifier.
So, is it enough to simply replace the RO membrane filter? In fact, although the RO membrane is the core of the filter, the role of other filters cannot be ignored as well. Imagine if other filters were dismantled or discarded, the entire filtration effect could be compromised. Therefore, it is a good idea to take other filters into account when replacing RO membrane filters. This not only ensures consistent filtration, but also avoids potential risks.
There are two main types of water purifier cartridges, each with its own merits. First of all, there are the traditional filter cartridges. This type of filter is relatively affordable, and you can easily buy a universal filter online. As long as you remember the flux of your own water purifier, the purchase process will become a breeze.
Generally speaking, the cost of replacing a set of filter elements is about 300 yuan, but you need to install it yourself. When buying a water purifier, it usually comes with a plastic sleeve. Use this sleeve to snap on the filter cartridge of the water purifier and turn it on with a slight rotation. Remove the old filter and insert the new one, and the replacement is complete.
The other is a composite filter. This type of filter can only be purchased from the original factory, and each model has its own filter, so there is no one-size-fits-all option. Therefore, it is relatively high, but it is usually much cheaper to buy at the official *** than from the after-sales service. It costs about 500 yuan to replace a set.
However, the replacement process is actually quite simple. These filters are hidden inside a plastic case. All you need to do is pull the old shell out and push the new shell in to complete the replacement. One of the major selling points of composite filters is the "ease of filter replacement". If you choose to pay someone to replace it, then the cost is a bit unjust.
