The Main Points of The Purchase of Water Purifiers: Careful Selection of Know-how
Water quality fit:
the water quality in different regions varies greatly, so before buying a water purifier, you should first understand the local water quality.
If the heavy metal content in the water is high, the water is hard or there are more dissolved solid impurities,
then it is recommended to choose reverse osmosis water purifier;
if the water quality is relatively good, there is only some slight odor, residual chlorine or microbial contamination,
ultrafiltration water purifier or activated carbon water purifier may be able to meet the demand.
Filtration effect:
The core function of a water purifier is to filter and purify water, so the filtration effect is a key consideration when purchasing.
Check the product’s filtration accuracy, filtration level and the filtration technology used and other indicators to understand what harmful substances it can remove.
Generally speaking, reverse osmosis water purifier filtration effect is the most comprehensive,
but ultrafiltration water purifier in the retention of beneficial minerals in the water has certain advantages.
At the same time, pay attention to whether the product has the relevant water quality test report or certification, such as NSF certification, WQA certification, etc.,
these certifications can be a certain degree of proof of the product’s filtration effect and quality and reliability.
Flux size:
the flux of the water purifier refers to its water production per unit of time, the larger the flux, the faster the water, the more convenient to use.
It is usually measured in gallons (G), and common fluxes are 400G, 600G, 800G and even higher.
For daily use in the home, if there are more family members or a greater demand for water,
Wastewater ratio:
reverse osmosis water purifier will produce a certain proportion of wastewater during the working process, the wastewater ratio refers to the proportion of pure water and wastewater produced.
The higher the wastewater ratio, the less water the water purifier consumes in the production of pure water, the more environmentally friendly and energy saving.
Some advanced reverse osmosis water purifiers on the market can have a wastewater ratio of 1:1.5 or even higher, while some ordinary products may have a wastewater ratio of about 1:3.
When shopping, try to choose products with lower wastewater ratios to reduce long-term costs and minimize water waste.
