Notice for purchasing purified water equipment

1： Look at the demand

The prices of purified water equipment for different raw materials and purposes also vary. Before purchasing, it is important to consider your own situation and choose the one that suits you, whether it is for ordinary household use, enterprise business use, or pharmaceutical industry use? Should we preserve minerals or affirm purified water? The hardness of water quality in the local area and other factors need to be considered.

If you want to preserve minerals, ****** choose an ultrafiltration model.

If you want water to be clean, you can choose a pure water machine, which is a reverse osmosis model.

2： Check qualifications

How important are qualifications? Let's not go into too much detail here. Let's list below what qualifications a qualified pure water equipment company needs?

1. National Drinking Water Hygiene Product Hygiene License

2. ISO Quality Management Certification System

3. CCC certification

4. AAA certification

5. Verification statement (for relevant statements on water quality testing, provide a reference: Puni testing statement)

6. Trademark registration certificate, tax certificate, and business license are also expressions of a company's value.

3： Look at the raw materials

Nowadays, the purified water equipment in shopping malls includes materials such as stainless steel, fiberglass, cast iron, aluminum grade, food grade resin, or PVC.

The first three types belong to raw materials with good compressive strength, which can be used as pre filters (central machines).

The latter two types of raw materials, which are classified as having poor compressive strength, can only be used at the back end of the pre filter (central machine) for use in direct drinking machines.

Among these raw materials for purified water equipment, stainless steel is the main material for compressive and corrosion resistance. The price is also relatively high. Food grade resins or PVC have poor compressive strength and relatively low prices.

4： Viewing membrane technology

According to the membrane process, the purified water equipment in the market is divided into ultrafiltration membrane water purifier, nanofiltration membrane water purifier, and RO membrane (i.e. reverse osmosis membrane) water purifier.

5： Check the after-sales service

After long-term use of purified water equipment, many consumables need to be replaced or cleaned. When purchasing, it is necessary to inquire with the seller for detailed after-sales procedures and shelf life.

In addition to the above points, consumers should also conduct comprehensive investigations from various aspects such as type and electricity consumption.
