Advanced Water Filtration Technology Suitable for Inlet Water

As mentioned in the previous article, there are 3 filtration technologies: RO, Nano, UF. These filtration technologies differ in filter membrane size. Depending on the quality of the incoming water, consumers can choose different types of filter membranes. The smaller the filter hole size, the purer and safer the filtered water.

Number of Filter Cores

Depending on the product line of each manufacturer, water purifiers have from 5-10 filter cores. The cleanliness of the filtered water depends on the number of water filter cores. For example:

When passing through the RO filter membrane, the water will be completely purified (comparable to distilled water, odorless, tasteless, colorless, and without nutrients).
The next filter cores (after the RO membrane) have the function of supporting mineral creation, nutrients, and enhancing the taste of the water.

Water Storage Capacity, Filtering Capacity per Hour

This is the criterion to meet the demand for clean water for various purposes, such as:

10-liter tank with a filtering capacity of 10 – 15 liters/hour: suitable for using clean water for washing faces, bathing children, cooking, brewing, etc. (meeting most daily activities).
8 – 10 liter tank and a filtering capacity of about 10 liters/hour: mainly suitable for cooking, drinking water.

Drinkable Water Quality Directly after Filtration

In Vietnam, the national standard for drinking water is QCVN6-1:2010/BYT, which applies to bottled and bulk drinking water such as Aquafina, Lavie… Directly drinkable water quality is the highest standard for evaluating the quality of a household water purifier. However, not every water purifier brand on the market dares to publicly announce that their machines meet this standard.

Additional Special Features

Replacement reminder for filter cores
Notification of water quality output

Hot-cold faucet for convenient coffee brewing, instant noodle cooking, and many other features!

Authorized Authentication Systems

There are currently more than 200 household water purifier brands on the market, many of which have products of inadequate quality or counterfeited from major brands. There are many tricks to counterfeit or reduce the quality of products, such as using similar names to famous brands, replacing genuine filter cores with Chinese or homemade products, which affect the health of consumers.

Water Purifier Price

In the current Vietnamese market, the average price of household water purifiers ranges from 3,500,000 VND to over 9,000,000 VND. With premium imported products like AO Smith, Coway, the price can go up to over 17 million VND. Water purifiers are daily health care devices, so consumers should not prioritize cheap prices and risk compromising their well-being.

After-Sales Service

Like other household appliances, household water purifiers also need maintenance to ensure optimal performance during use. In addition, as the product comes into contact with water and filters impurities, incidents such as water leakage, strange noises, clogged filter cores, etc., can occur. Therefore, choosing a brand with a 24/7 customer service center will help you promptly handle incidents, as well as maintain and care for water quality and machine quality throughout the usage period.

Warranty Policies

Before making a purchase, you should consider the product’s warranty period to ensure peace of mind during usage. Currently, most brands offer a maximum warranty period of 12 months, but some brands provide a longer warranty period of up to 36 months, such as Karofi.

Tips for Using a Durable and Long-lasting Water Purifier

Clearly Identify the Water Source to Choose a Suitable Water Purifier

Using a suitable water purifier for the water source is crucial. Sometimes, spending more money on a water purifier does not necessarily mean it will be better or more durable. For example, if you buy an AOSMITH water purifier but your water source is not clean, has a lot of impurities, and contains limestone… the filter cores will clog quickly and the water quality will not meet your expectations.

Regularly Replace Filter Cores

On average, you should replace the filter cores every 6-12 months. However, in areas with heavily polluted water sources that do not meet standards, the replacement time for this product line may be shorter.

Properly Clean the Water Purifier

Properly cleaning the water purifier is also crucial. This helps us avoid dirt, rust, dust, which can affect our health. You should follow these steps:

Use a soft, damp cloth to properly wipe away dirt on the product’s surface.
Avoid the appearance of rust at the faucet head, which can affect the water and cause stomach pain.
Thoroughly remove dirt from the filter cores and the components inside the container that holds the machine’s components.
Place the water purifier in a dry place and avoid damp environments.
