How to choose a Doulton countertop water filter

Before choosing a water filter, you must do your homework beforehand to determine which filter would be the most suitable for you. Among the Doulton countertop water filters, the most well-known product series are M12 and M15. It is also necessary to recognize the two major elements of filtration type and shell material. This could, to a very large extent, affect the price of the water filters.

Filter Category

The water filter will be marked with the different types of filter elements used. For example, the water filters shown above uses BTU (BioTect Ultra), UCC (Ultracarb), and HPU (High Porosity Ultra) filter elements. They are a comparison of the three main filter elements of Doulton’s countertop water filters.

 

  • UCC (Basic Efficiency): It is the standard version of the filter element, which is only suitable for BSP series water filters. Having said that, this does not mean that its filtering efficiency is poor. All relevant certifications (NSF42 and 53) have been met. If you only require the simplest filtering function, such as isolating lead water, UCC is sufficient for you.

  • HPU (Medium Efficiency): It is suitable for a series of water filters, including the M15 series. The HPU filter element adopts "high-density channel technology" to control the size of the filter channel. The smaller the filter pores are, the greater the water pressure required. If the diameter of the filter pores differs, the filtered water will flow to the larger channel. Consequently, if there is insufficient water pressure, water will not flow through and will cause the failure of the filtering function. With the “high-density channel technology,” the micropores are evenly distributed, and therefore achieving the best quality of filtered water.

  • BTU (High Efficiency): The BTU filter element is only applicable to the M12 water filter series. BioTect "nano-antibacterial technology" is added in the production process. The material molecules range in the size of 0.1 to 100 nanometers and are reorganized to improve product performance and efficacy. This makes the filter structure more orderly and the pore size smaller, thereby greatly enhancing the antibacterial function of the filter element.

Shell Material

Doulton water filters come in different models, such as DCP, DUS, HCS, HIP, etc. They may have different designs, but they all end in S or P which represents the materials used in the water filter housing. The P tail model refers to a plastic case, while the S tail refers to a stainless steel case. Although the stainless steel shell version is more costly in comparison, it is relatively more durable with a life of over 5 years; the plastic shell generally lasts for 3 to 4 years and has physical limitations. For example, it cannot remain with close proximity to heat sources such as cooking stoves, or long-term sunlight.

Product review This traditional design is equipped with a stainless steel shell and BTU filter element. If you don’t like a higher water level, you may consider this model. Developed the HPU filter element, but the design of the higher water level remains the same. If you don’t need a top filter and you like a stainless steel casing, this one would be your best choice.

Product review It costs $609 to buy a filter alone, but you can also get the full set of water filters for an additional $269, which is the best offer. The high water level design is located on the top of the water filter, which is different from other models. It is also more durable with the stainless steel housing. The price of the plastic shell is cheaper, and the BTU filter element is the best choice.

The BTU filter element has the strongest filtering performance, so it is a top choice for most people. Among the 7 countertop water filters compared this time, 5 of them use BTU filter elements. There are also plastic shell styles available for purchase; among them, the M12 series DBS+BTU 2501 countertop water filter is the more popular style, and the stainless steel case is more durable. The product has a more obvious effect in filtering heavy metals and bacteria, and is especially suitable for household use in old buildings or village houses where the quality of drinking water is relatively low.

 

Among the three types of filter elements, BTU can filter the most substances. Therefore, the Doulton countertop water filter with BTU filtration element is generally more expensive.

In addition to the aforementioned three filter elements, Doulton also has other types of filter elements including:

  • EWC: The filter element contains KDF material made in the United States, which can remove up to 99% of soluble lead, mercury and other heavy metals, and can control the growth of bacteria, fungi, and algae.
  • FRC: FRC is a chlorine removal filter that can absorb chlorine gas in water up to 3,370 ppm

 

Each water filter has its own unique element. You can't replace it with other types of filter elements, so pay attention to the product description for specific details.

 

Tip: What is the difference between BTU2501 and BTU2504?

Attentive friends will find that there will be a set of 4 numbers after the filter element model, for example, BTU has BTU2501 and BTU2504. Simply put, BTU2504 is an older model, and BTU2501 is a new upgraded version launched in 2019 and is fully compatible with BTU2504. As a result, when buying a filter element, you may wish to pay attention to these numbers, so that you don’t mistakenly buy the older model.

 

As for other types of filter elements, the resolution principle is the same, 01 is the new model, 04 is the old model. Be sure to remember this!

Doulton vs. 3M Water Filter

Finally, I’ll present to you the two major water filter brands: Doulton and 3M. Both of them are big brands, but they are not comparable in performance. This time, we compare compare some of their common parameters instead of selecting specific models. This comparison may not be comprehensive and is mainly intended to give you a simple reference before your purchase.

Doulton Compare items 3M

Filter material Activated carbon
HK$400-HK$600🏆 Filter Price(single) HK$500-HK$1,200
2,300 liters microns 2,839 liters 🏆

 

As you can see, in regards to the NSF certification, both company’s filtration capacity is the same. The filter life is slightly better in 3M, which means that the interval between core changes is longer, but considering the price of the filter, this advantage becomes less apparent.

 

The biggest advantage of 3M is that you can use the sticky notes to hang the water filter on the wall, enough to save space; however, 3M water filters come from different places, so make sure you pay more attention before buying!
