4. Grasp the 4+ factors that affect the price of replacing water purifier cores
The price information mentioned in the article is for reference only. In fact, the selling price of each type of core can be adjusted up/down based on many factors. Specifically:
- Core type: The machine's filtration system includes many filter cores with different structural characteristics and roles. Accordingly, the cost for each core will also have a certain difference. Specifically, alkaline water purifiers with Hydrogen Alkaline Ion core technology will have a mid-range price.
- Supply brand: Components installed for products of large and reputable brands often have to meet strict inspection standards. Each brand will have different technologies and standards in the filter core, leading to product price differences.
- Warranty policy of replacement core: Genuine cores are often more expensive but come with a warranty policy on quality, durability and features of the component. On the contrary, if you choose a floating core of unknown origin, the cost may be lower but your rights will not be guaranteed during use.
- Repair/replacement unit: There are currently many units on the market that provide components and support repair and replacement of water purifiers. Of course, each place will have different pricing policies for their services. In this situation, you should proactively consult prices at several units to get a general price, avoiding being overcharged. However, you should not choose addresses that quote too low because that may reflect that the quality of the core and the accompanying after-sales service are not guaranteed.
