This is a stupid thing if you pin your water filter on a small TDS pen. Undoubtedly, according to the quality of the water filter from every aspect, the TDS test pen is effective, but this does not necessarily mean that the water filter has worked.
0-50 ——- High purity of water
50-100 ——- the purity of water is higher
100-300 ——- The purity of water is average
300-600 ——- will cause scale
600-1000 ——- Poor taste of water
Greater than 1000 ——- not suitable for drinking

If the TDS value of the water is below 100, it indicates that the water filter is effective, and the value decreases, indicating that the tap water has been filtered.
TDS: Total dissolved solids, is the equipment used to measure the total amount of the three solid substances in water. The higher the TDS value, the more the dissolved matter in the water.
Can TDS judge the quality of a water filter?
Can’t. TDS is only an indicator to judge whether the water is good or bad. The important thing is that the low TDS does not mean that the water will be very clean. So TDS cannot be used to judge the quality of a water filter.
What is the use of TDS?
If the TDS value drops, it means that the water has indeed been purified to determine whether the water filtration is actually working.

Factors that cause inaccurate TDS values:
1. Water temperature: TDS pen cannot be used to measure high temperature water
Under normal circumstances, when the water temperature rises, the calcium and magnesium ions in the water combine with other substances, and the electrical conductivity increases, so the TDS value will also increase, which will affect the detection result.
2. Serious water pollution: water with high pollution concentration affects the measurement data
In some areas of China where the TDS value is high and even some groundwaters amount to thousands, if the raw water quality is seriously polluted, it is recommended to add a pre-protection before using RO reverse osmosis pure water machine.
3. Other influencing factors
①The newly installed machine, or the machine with a new filter element, need to be rinsed with water for 20-30 minutes before measuring;
②The storage time of pure water in the water storage tank is too long, which will also affect the measurement results.

Some merchants will introduce some water filters, which can change the TDS value to very low, which is and does not necessarily say what the name water filtration is good. Buying a water filter requires your careful consideration.

PP sediment filter is one of the most commonly used water filter elements. They can efficiently remove impurities and contaminants in water, such as rust, small bugs, stones, etc. At the same time, PP sediment filter can also protect the core part of the water filter, such as RO membrane, UF membrane, etc. When you buy a PP sediment filter, the merchant will tell you that the PP sediment filter needs to be replaced in 3-6 months. Have you ever thought about cleaning the contaminated PP sediment filter and then continuing to use it?

If you have a private swimming pool, then you know that the pool filter can be cleaned and used again. But can PP sediment filter do the same?
In order to save costs, some users will intentionally delay the replacement of the PP sediment filter, and even some people will take out the PP sediment filter for cleaning and then use it again. Is this really okay? In fact, PP sediment filter cannot be cleaned. First, there will be a lot of pollutants on the surface and inside of the PP sediment filter after being used. Even if the surface pollutants are cleaned, the pollutants inside the PP sediment filter are difficult to clean. Secondly, there will be a lot of bacteria in the PP sediment filter after being used. These bacteria will not be cleaned. The PP sediment filter may threaten our health if it is used again. Finally, the internal structure of the PP sediment filter is easily damaged when it is cleaned, so that the PP sediment filter will not work.

Therefore, PP sediment filters need to be replaced in 3-6 months instead of cleaning them. There are some things you need to pay attention to when using PP sediment filter.
1. When the water purifier is not used for more than three days, the water filter should be drained for 2-5 minutes when it is used again, until the water in the water purifier is drained.
2. When the tap water is stopped, please turn on the sewage faucet to drain out the sediment, rust, etc. in the tap water pipe, and then turn on the purified water faucet to use purified water.
3. When the water purifier fails, please immediately close the tap water inlet valve, cut off the water inlet of the water purifier, and then contact the after-sales service personnel. Do not disassemble it by yourself.

Before you buy any type of water for your home, whether a jug from the store, a filter or even a water cooler, it’s wise to know more about the various water filtration methods that may have happened before you take a sip. Some filtration methods are better at removing particles and contaminants than others. Here’s a quick overview of each type of water filtration method.

1. Activated Carbon Water Filtration
Carbon removes contaminants by chemically bonding to the water that is poured into the system. Some are only effective at removing chlorine, which only improves taste and odor, while others remove more harmful contaminants, such as mercury and lead. It is important to note that carbon filters do not have the ability to remove inorganic pollutants such as nitrates, fluoride, and arsenic. Carbon filters are usually sold in block or granulated form to consumers.

2. Distillation Water Filtration
Distillation is one of the oldest water purification methods. It vaporizes water by heating it to exceptionally high temperatures. The vapor is then condensed back into drinkable, liquid water. Distillation removes minerals, microorganisms, and chemicals that have a high boiling point. These filters cannot remove chlorine and many other volatile organic chemicals.

3. Deionization Water Filtration
Deionization filters promote ion exchange in your water in order to remove salts and other electrically charged ions. If a contaminant lacks an electrical charge, it will be removed by these filters. Living organisms, such as viruses and bacteria will not be removed by these filters.

4. Ion Exchange Water Filtration
Ion exchange technology uses a resin to replace harmful ions with ones that are less harmful. Ion exchange is often used to soften water since it has the ability to replace calcium and magnesium with sodium. In order for these filters to work for extended periods of time, the resin must be regularly “recharged” with harmless replacement ions.

5. Reverse Osmosis Water Filtration
Reverse osmosis works by moving water through a semi-permeable membrane in order to stop larger, more harmful molecules from entering. Since this process can only block molecules that are larger than water, contaminants with larger molecules, such as chlorine, cannot be removed. Reverse osmosis systems are able to remove more contaminants than carbon, making them a popular choice for many consumers. These filters consume far more water than they produce, so they are best suited for domestic use.

6. Mechanical Water Filtration
Water Filtration Methods: How to Purify Your Drinking Water
Despite the fact that they cannot remove chemical contaminants, mechanical filters are an excellent option for consumers hoping to rid their water of sediments and cysts. Mechanical filters contain small holes that remove these contaminants, and they are sometimes used alongside other filtration technologies. If your water supply contains an undesirable amount of dirt and other particles, you may want to consider purchasing a mechanical filter.

7. Ozone Water Filtration
Ozone is often employed alongside other technologies, and it is renowned for its ability to effectively kill large numbers of microorganisms. Ozone filters do not remove chemicals, but if you are worried about getting sick from your water, this may be your best option.

8. Carbon Block Water Filtration
Carbon block filters are block-shaped filters that are composed of crushed carbon particles. These filters tend to be more effective than other types of carbon-based filters since they have a larger surface area. The rate at which water flows through these filters has a direct impact on their level of effectiveness. Fibredyne carbon block filters have a greater sediment-holding capacity than other types of block filters.

9. Granulated Carbon Water Filtration
As the name suggests, these filters use small grains of carbon to filter your water. Due to their rather small surface area, granulated carbon filters tend to be slightly less effective than their block-shaped counterparts. Much like a carbon block filter, their level of effectiveness is strongly influenced by water speed.

10. Water Softeners Water Filtration
Water softeners employ ion exchange technology in order to reduce the amount of magnesium and calcium in the water. This is especially useful if your plumbing fixtures are prone to accumulating mineral buildup. Since these harmful elements are replaced with sodium, water treated with this process tends to contain high levels of sodium. If you cannot consume large amounts of salt, it is best to avoid softened water. It is also unwise to water plants with softened water since it contains such high levels of sodium.

There are various types ofwater filters available to consumers. Here are some of the most common types, along with their advantages and disadvantages:

Pitcher water filters:
Pitchers usually contain carbon filters that improve the taste and odor of your water by removing contaminants. These filter types are inexpensive and fit easily inside of most refrigerators.

Under-Sink water filters:
As the name implies, under-sink filters are installed underneath your sink and are attached directly to your water line. They can be expensive, but they require little maintenance and are placed out of sight.

On-Counter water filters:
On-counter filters are placed on the counter, and are directly connected to your faucet. A switch allows consumers to switch between filtered and unfiltered water. Countertop water coolers are a popular, hassle-free way to get purified water with little work.

Faucet-Mounted water filters:
Faucet-mounted filters attach directly to your faucet, allowing you to filter cooking and drinking water with ease. These filters are fairly simple to install, but they may not fit on all faucets.

Every water filter and many purifiers include an internal element or cartridge, a component that has microscopic pores that catch debris, protozoa and bacteria. Over time, strained matter gums up an element’s pores, requiring it to be cleaned and eventually replaced.

Most purifiers use chemicals (such as iodine) to kill viruses, which are too small for most filter elements. Another purification method relies instead on ultraviolet light to treat the pathogens.

Many filters and purifiers also include activated carbon in their elements because it’s effective at removing unpleasant tastes from things like leaf tannins. Activated carbon also reduces contaminants like pesticides and other industrial chemicals.
