How to Choose The Right Water Purifier

(A) choose according to the water quality

1. Understand the local water source
2. If you are using municipal tap water, you can learn about the water quality report from the local water supply department, including the hardness of the water, heavy metal content, microbial indicators. For example, if the hardness of the water is high and there is an obvious scale problem, you can consider choosing a water purifier with ion exchange function, such as nanofiltration or reverse osmosis water purifier. If the microorganisms in the water exceed the standard, ultrafiltration or reverse osmosis water purifier may be a better choice. For some areas where groundwater is used as the source of water, it may be necessary to focus on the levels of iron, manganese and other metal ions in the water and bacterial contamination.
3. Testing household water
4. You can buy some simple water quality test kits, such as water quality test paper, TDS (total dissolved solids) test pen, etc., to test the water coming out of the faucet in the home. If the TDS value is too high, it means that there are more dissolved solids in the water and you may need to choose a reverse osmosis water purifier. At the same time, observe the color and smell of the water. If there is a strange smell or color, you may need to choose a water purifier with activated carbon adsorption function.

(ii) Selection according to the use of demand

1. Family Drinking Needs
2. If the main purpose is to meet the family’s direct drinking needs, reverse osmosis water purifier can provide the purest water quality. However, if you want to retain some beneficial minerals in the water, ultrafiltration or nanofiltration water purifier is also a good choice. For families with infants and young children, the water quality requirements are even higher, and reverse osmosis water purifiers can better protect the drinking water safety of infants and young children.
3. Household Water Needs
4. If you wish to purify the entire household’s domestic water to a certain extent, such as protecting equipment such as washing machines and water heaters, a centralized water purifier is a suitable choice. For kitchen water, if you want to get purified water conveniently and quickly, under-counter or over-counter water purifiers can meet the demand, which can be chosen according to the space in the kitchen and personal preferences.

(iii) Consider the cost factor

1. Purchase cost
2. The price of different types and brands of water purifiers varies greatly. Generally speaking, reverse osmosis water purifier price is relatively high, especially some high-end brands with intelligent features. While countertop water purifiers have a wider range of prices and can be chosen according to your budget. When buying, don’t just look at the price, but consider the performance, quality and after-sales service of the water purifier.
3. Cost of use
4. The cost of use mainly includes the cost of filter cartridge replacement and utility costs. Reverse osmosis water purifier due to the need for high-pressure pumps and other equipment, relatively speaking, utility costs may be higher, and its filter replacement is more frequent, the cost is also higher. While microfiltration, ultrafiltration and other water purifiers cartridge replacement costs are relatively low. When choosing a water purifier, according to their affordability and frequency of use to calculate the long-term cost of use.
