Water purifiers for households are practically indispensable in the daily lives of Vietnamese families. This device helps filter out impurities, dirt in water, providing cleaner water, as well as supplying additional minerals and protecting the health of users.
1. Top Tips for Buying the Best Water Purifier You Need to Know
1.1. Water Source Status
You need to check the quality of the water source where you live to make the right choice of household water purifiers. Check the quality of the water source where you live by taking water samples to the testing center or testing at home with a DTS test pen or an electrolytic pen.
- Water Sources: Basic water sources like tap water, well water, or rainwater typically have low pollution levels. You can choose a reverse osmosis (RO) water purifier with 3 – 4 cores to filter out residual impurities. Some models come with additional mineral supplements for healthier water (5 – 10 cores).

Purpose and Economic Viability
Considerations: When buying a home water purifier, consider its purpose and economic viability.
- Household Usage: For general household use (washing, bathing), opt for a high-capacity machine. For drinking and cooking purposes, choose a smaller or medium-sized direct drinking household water purifier to save costs.
Size: Also, consider the size of the water purifier. For spacious areas, a large-capacity purifier can be used. For smaller spaces, consider a compact desktop purifier for convenient and quality water output.
Types of Water Purifiers You Should Know
Currently, there are two main types of home water purifiers on the market: RO and Nano. Each type has its own advantages and disadvantages, suitable for different water sources and purposes. Therefore, depending on your usage needs and the condition of the water source, you can choose the type of water purifier that suits you best.
RO water purifiers apply RO water filtration technology, which can remove most solid particles, heavy metals, bacteria, etc., providing pure drinking water that can be consumed immediately without boiling. Thus, the body will absorb through the ultra-fine filter membrane (0.0001 - 0.0005 micrometers).

With this technology, the output water source will ensure purity while also being supplemented with minerals, creating good water for health. In addition, some models also have the ability to filter brackish water, salty water, and hard water.
Nano water purifiers use Nano water filtration technology to effectively remove impurities, dust, various bacteria, and viruses contained in the input water with ultra-small filter membranes ranging from 0.01 to 0.1 micrometers. Moreover, it helps retain beneficial natural minerals for the health of users.
Nano water purifiers use Nano water filtration technology to effectively remove impurities, dust, various bacteria, and viruses contained in the input water with ultra-small filter membranes ranging from 0.01 to 0.1 micrometers.
