Compare Before You Buy"},"content":{"rendered":"

The Cleansui EU101 and EU301 are both built-in water purifiers designed to be installed under the sink or kitchen counter, so they\u2019re two models many people compare when they want a purifier with the unit hidden away below. From the outside, the two may seem to share a similar concept: both are home filtration systems with a cartridge capacity of 8,000 liters. But in fact, the EU101 and EU301 have important differences, especially when it comes to alkaline water production and electricity use.<\/p>\n\n\n\n

The EU101 is a built-in water purifier focused on filtering water for drinking and cooking, while the EU301 adds an alkaline ionizer, so it can produce alkaline ionized water after filtration.<\/p>\n\n\n\n

So the question \u201cCleansui EU101 vs EU301: which is better?\u201d shouldn\u2019t be answered by price or number of features alone. Start instead with whether you want plain filtered water or filtration plus alkaline water. This article compares the two models in detail, from the filtration system, cartridges, installation, power use and faucet to cartridge life and costs, to make your choice easier.<\/p>\n\n\n\n

Cleansui EU101 vs EU301: What\u2019s the Difference?<\/strong><\/h2>\n\n\n\n

The biggest difference between the EU101 and EU301 is that the EU301 has an alkaline ionizer and the EU101 doesn\u2019t. The EU101 is a built-in filtration system that sends water through the cartridge and out of the filtered-water faucet, while the EU301 adds a step after the water passes through the cartridge: electrolysis, which uses electricity to split the water and produce alkaline ionized water. Here\u2019s a summary of the main differences:<\/p>\n\n\n\n

*Cartridge life depends on water usage and the manufacturer\u2019s conditions of use.
The EU101 uses the EUC2000 cartridge, while the EU301 uses the EUC3000. Both have a cartridge capacity of 8,000 liters and last about 12 months under the specified conditions (cleansui.com<\/a>)<\/p>\n\n\n\n

What Is the Cleansui EU101?<\/strong><\/h2>\n\n\n\n

The Cleansui EU101 is a built-in water purifier designed for under-sink installation: the filter unit sits below, with a faucet on the counter that dispenses filtered water.<\/p>\n\n\n\n

The EU101\u2019s strength is that it\u2019s a fairly simple system, focused on filtration without adding alkaline water production.<\/p>\n\n\n\n

The EU101 uses the EUC2000<\/strong> cartridge, which consists of a polyethylene hollow fiber membrane, activated carbon, ion exchange fiber and nonwoven fabric, according to the manufacturer (cleansui.com<\/a>)<\/p>\n\n\n\n

This filtration system can reduce many kinds of substances, such as chlorine, turbidity, soluble lead and certain compounds, according to the product\u2019s specifications and test results. For homes that want filtered water for drinking, cooking or making drinks without needing an added alkaline system, the EU101 is the straightforward choice. Another point of interest is that the EU101 doesn\u2019t need electricity to filter water, which makes it a good fit for people who want an uncomplicated system that\u2019s easy to install.<\/p>\n\n\n\n

What Is the Cleansui EU301?<\/strong><\/h2>\n\n\n\n

The Cleansui EU301 is a built-in water purifier at heart, just like the EU101, but it adds an Alkaline Ionizer<\/strong> system.<\/p>\n\n\n\n

So the process doesn\u2019t end once the water passes through the cartridge: the system can send the filtered water through electrolysis to produce alkaline ionized water.<\/p>\n\n\n\n

Cleansui states that the EU301 lets you choose the type of water using controls on the faucet, providing both filtered water and ionized water depending on the mode (cleansui.com<\/a>)<\/p>\n\n\n\n

The EU301 uses the EUC3000<\/strong> cartridge, which has a capacity of 8,000 liters and lasts about 12 months when used under the conditions specified by the manufacturer.<\/p>\n\n\n\n

So the difference between the EU101 and EU301 isn\u2019t just a matter of different levels of filtration. The EU301 is a system that adds a water-conditioning function after filtration.<\/p>\n\n\n\n

Do the EU101 and EU301 Use the Same Cartridge?<\/strong><\/h2>\n\n\n\n

No, they\u2019re not the same.<\/strong><\/p>\n\n\n\n

The EU101 uses the EUC2000<\/strong><\/p>\n\n\n\n

The EU301 uses the EUC3000<\/strong><\/p>\n\n\n\n

Although both models have the same cartridge capacity of 8,000 liters, you should use the cartridge that matches your unit, because the EUC2000 and EUC3000 shouldn\u2019t be assumed to be interchangeable.<\/p>\n\n\n\n

The EUC2000 is for under-sink filtration systems and the EUC3000 is for the model with an alkaline ionizer, so always check your unit\u2019s model code before ordering a cartridge.<\/p>\n\n\n\n

How Do the EUC2000 and EUC3000 Differ?<\/strong><\/h2>\n\n\n\n

The EUC2000 and EUC3000 both have a capacity of 8,000 liters, but they\u2019re designed for different systems.<\/p>\n\n\n\n

The EUC2000 is a cartridge for a standard water purifier, using hollow fiber membrane and activated carbon technology along with other filter media. The EUC3000 is used in the system with an alkaline ionizer and has to work together with the EU301\u2019s alkaline water production system. So don\u2019t simply assume that<\/p>\n\n\n\n

EUC3000 = higher model number = better filtration than EUC2000<\/strong><\/p>\n\n\n\n

The cartridges do different jobs and work with different systems, so your choice should depend on the unit you use and the functions you need.<\/p>\n\n\n\n

Do the EU101 and EU301 Filter Water Differently?<\/strong><\/h2>\n\n\n\n

Both models can reduce many types of contaminants, but you shouldn\u2019t assume the EU301 filters better than the EU101 just because it has an alkaline system. The key difference with the EU301 is its ionizer after filtration, while the EU101 focuses directly on filtering water.<\/p>\n\n\n\n

For the EU101, the EUC2000 system consists of activated carbon and a hollow fiber membrane, plus ion exchange fiber and nonwoven fabric (cleansui.com<\/a>). The EU301, meanwhile, uses the EUC3000 and adds an alkaline ionizer.<\/p>\n\n\n\n

So if what you need is filtered water, either model will do the job. But if you want filtered water that also goes through alkaline water production, you\u2019ll need to consider the EU301.<\/p>\n\n\n\n

How Do the EU101 and EU301 Differ on Alkaline Water?<\/strong><\/h2>\n\n\n\n

This is the most important difference between the two models.<\/p>\n\n\n\n

The EU101 filters water but has no alkaline water production system.<\/p>\n\n\n\n

The EU301 has an alkaline ionizer that can turn filtered water into alkaline ionized water, depending on the mode.<\/p>\n\n\n\n

This process uses electricity to split the water through electrolysis, and it gives the EU301 more functions than a standard water purifier. However, having an alkaline water system doesn\u2019t mean every home needs one. If your main need is filtered water for drinking and cooking, a purifier that matches that need is enough. So it\u2019s worth separating filtration performance from alkaline water production, because they\u2019re two different functions.<\/p>\n\n\n\n

Which Uses Electricity, the EU101 or the EU301?<\/strong><\/h2>\n\n\n\n

The EU101 doesn\u2019t need electricity for the filtration process.<\/p>\n\n\n\n

The EU301 has an alkaline ionizer, so it needs electricity for the ionization process.<\/p>\n\n\n\n

This is one of the differences to consider when installing, because the EU301 needs a suitable power supply under the sink. If you\u2019re renovating your kitchen, plan the outlet location and the plumbing together so the EU301 can be installed without having to modify things later.<\/p>\n\n\n\n

How Do the EU101 and EU301 Faucets Differ?<\/strong><\/h2>\n\n\n\n

The faucet design is another difference, since the EU301 needs controls to select the water function. The EU301 has control buttons on the faucet to choose the type of water, while the EU101 has a faucet that simply dispenses filtered water.<\/p>\n\n\n\n

So if you want a kitchen with a simple faucet setup, the EU101 has the more straightforward design, while the EU301 suits people who want to control the type of water and make use of the alkaline ionizer.<\/p>\n\n\n\n

Do Cartridge Costs Differ Between the EU101 and EU301?<\/strong><\/h2>\n\n\n\n

The two models use different cartridge codes, but the prices are at the same level (prices may change with promotions).<\/p>\n\n\n\n

EUC2000<\/strong> for the EU101, priced at 6,320 baht<\/strong><\/p>\n\n\n\n

EUC3000<\/strong> for the EU301, priced at 6,320 baht<\/strong><\/p>\n\n\n\n

Based on a life of about 12 months:<\/p>\n\n\n\n

6,320 \u00f7 12 = about 527 baht per month<\/strong><\/p>\n\n\n\n

So in terms of cartridge cost alone, the EU101 and EU301 cost about the same at current prices. The difference in overall cost should therefore be judged by the unit price, the electrical setup and other expenses rather than the cartridge cost alone.<\/p>\n\n\n\n

How Do the EU101 and EU301 Differ in Price?<\/strong><\/h2>\n\n\n\n

Unit prices can change over time, with promotions and with the bundled equipment sold, so a price from any one point in time shouldn\u2019t be treated as a fixed figure in an article. What\u2019s more useful to compare is:<\/p>\n\n\n\n

EU101<\/strong><\/p>\n\n\n\n

Unit price + EUC2000 cost + installation cost<\/p>\n\n\n\n

EU301<\/strong><\/p>\n\n\n\n

Unit price + EUC3000 cost + installation cost + electrical work\/related installation<\/p>\n\n\n\n

If you don\u2019t need alkaline water, buying the EU301 may mean paying for features you won\u2019t use. On the other hand, if you already want an alkaline water system, choosing the EU301 from the start may save you from installing an additional system later.<\/p>\n\n\n\n

Who Is the Cleansui EU101 For?<\/strong><\/h2>\n\n\n\n

The EU101 suits people who want an under-sink water purifier for everyday use, focused on filtered water for drinking, cooking and making drinks.<\/p>\n\n\n\n

The EU101 is a good fit if you:<\/p>\n\n\n\n
