Things you should know before choosing 'Drinking water filter' to install at home for clean drinking water.
Types of drinking water filters
1. Drinking water filter system RO (Reverse Osmosis System)
It is a drinking water filter that uses water pressure to push through a membrane filter with a resolution of 0.0001 microns, causing contaminants from water that are 50-0.0002 microns in size, such as heavy metals, chemicals, viruses, and bacteria. cannot escape through the filter membrane. along with being immediately removed from the system It also completely eliminates unwanted odors. Makes you get pure water But at the same time, with this precision, the water will not have any important minerals left. Including the need to install together with a water pump to help increase water pressure, it may be expensive. Most often use PP filters, carbon filters, resin filters, RO filters along with this water filter system.
2. UV drinking water filter system (Ultraviolet Filtration System)
It is a water filter that is similar to an RO system, but has less filtration efficiency. There is a water filtration process using ultraviolet technology. Inside the machine there is a UV lamp, which is a concentrated light charge. That helps to kill germs, bacteria, microorganisms and viruses. Including helping to filter odor, color, and chlorine, but without causing loss of minerals within the water. But there are a few limitations of UV water filters in that they are more suitable for use in filtering tap water than groundwater. Water from natural sources that contain a large amount of suspended sediment. Or you may choose filters that are effective in filtering out sediment such as PP filters, carbon filters, resin filters, UF filters, etc. to get clean drinking water at all times.
3. Drinking water filter system eSpring System (eSpring System)
It is a modern water filtration system today that is easy to use and convenient. It consists of a UV lamp and activated carbon (Carbon) in the same machine. To help kill germs Eliminates bacteria and viruses, effectively trapping dirt sized 0.2 microns. And also get important minerals at the same time such as calcium, magnesium, fluoride. There is also a system to remind you to change the filter when its lifespan is complete. But the price of the unit and filter may be higher than other types of drinking water filters.
4. UF drinking water filter (Ultra Filtration System)
It is a water filter with an ultrafiltration filter. Inside the filter there are thousands of small and fine synthetic fibers that have the ability to qualitatively separate water and foreign substances with particles as small as 0.01 microns, such as bacteria, protozoa, suspended solids, etc. Does not lose important minerals to the body such as sodium, calcium, magnesium, etc. Suitable for filtering tap water rather than raw water sources. Moreover, this water filter system has the advantage that you can change the filter yourself. Easy to install and reduce maintenance costs. Most often used with PP filters, resin filters, carbon filters, UF filters, post-carbon filters.
5. Drinking water filter MF (Micro Filtration System)
It is a membrane filtration system with small pores approximately 0.1 microns that helps separate particles sized 0.1-10 microns from suspended solids. Suitable for use in filtering water that has problems with brackish water, salt water, and hard water. It can also filter out colours, odors and germs. They are most often used to filter water for use rather than drinking water. But nowadays, manufacturers of various brands have developed them to be able to use with drinking water filters. But it must be used in conjunction with a filter that has sediment filtering properties to increase the purity of the water quality. It is often used with PP filters, carbon filters, MF filters, etc.
What types of filters are there in drinking water filters?
- Polypropylene filter element (Polypropylene or PP) : Or another name called a coarse filter (Sediment filter). It is the first layer of the filter. It is a filter made from a type of plastic, taken in the form of small fibers before being compressed into bars with sizes starting from 1 micron or more to help trap dust and suspended substances such as gravel, sand, soil, stones, etc., but they will last a lifetime. The short length makes it necessary to replace it frequently every 3-6 months.
- Carbon filter (Carbon) : produced from carbon fibers and wrapped with another layer of mesh. There are small holes in the mesh to help absorb odors, chlorine, and chemicals in the water. To get drinking water that doesn't have a bad smell. and there are no foreign contaminants Some systems have a Post Carbon filter that improves the taste of the water. and pH value as well This filter should be changed every 3-6 months or 6-12 months, depending on the quality of water in each area.
- Resin filter : It is a type of water filter that helps filter limestone, calcium, and magnesium in the water and exchange it for sodium instead. To prevent hard water and prevent your body from getting too much tartar. Because although these minerals are beneficial to the body, if you get too much It may increase the risk of kidney stones. And the filter should be changed every 6 months or every 1 year. This type of filter is often used with water filters that filter groundwater or brackish water.
- RO (Reverse Osmosis) filter : It is a very fine filter consisting of a membrane. They are generally found in RO water filters to help filter out viruses, bacteria, and dirt, including various minerals that have small particles. Makes drinking water of good quality and has a lifespan of approximately 6 months to 1 year
- UF (Ultra Filtration) filter : Made from polysulfone (PS) material with pores approximately 0.01 microns, used to trap small sediments, bacteria, dust and various germs, but not yet able to filter viruses. Commonly used with UF water filter systems and is more suitable for filtering tap water than for raw water. This filter may last approximately 3-7 years.
- MF (Micro filtration) filter : Made from synthetic materials. It has the ability to filter dirt and suspended substances in particles of approximately 0.1-10 microns. It is often used in conjunction with the MF system water filter as well. This filter has the advantage that it can be easily removed to clean the external surface. But even then, it should be replaced every 1 year.
- E-Spring filter : It can be said to be the most modern filter today. Because it has a UV filter and activated carbon. It has more holes than general filters. Helps trap small dirt particles and kill germs, viruses, and bacteria. The lifespan of this type of filter usually lasts approximately 1 year.
How to buy a drinking water filter
- Check the characteristics of the water in our area, whether it is tap water or groundwater. To choose a water filter and filter appropriately Helps extend the life of the water filter and water filter longer.
- Consider the number of people in the house who use drinking water. Because it will help you decide whether you should use a small or large water filter.
- Check the certification standard mark and product warranty
- Check service for installing or replacing filters for each brand of water filter. For our own convenience
- You should compare the prices of each model with the same features. To help save your spending budget to another level and still get clean, quality drinking water.
