What should I know before buying a water purifier?
Water Purifier Buying Guide
✅Water qulity-Choose water purifier type
There are generally two types of under-the-kitchen water purifiers, ultrafiltration and reverse osmosis.
🔸Ultrafiltration: Suitable for areas with good water quality, it can retain minerals but cannot filter heavy metals.
🔸Reverse Osmosis: Suitable for areas with poor water quality such as high-rise buildings and old communities, with more thorough filtration.
Population - Determine flux size
The larger the flux, the faster the water will flow out, and the filtration effect will be the same, but the noise and cost will increase.
🔸400G: Suitable for 3-4 people, flow rate is about 1.05L/min.
🔸600G: Suitable for a family of 6-7, with a flow rate of about 1.58L/min.
🔸800 and 1000G: Suitable for families with a large number of people and who need fast water supply.
Material-Whether it is food grade raw materials
The larger the flux, the faster the water will flow out, and the filtration effect will be the same, but the noise and cost will increase.
🔸400G: Suitable for 3-4 people, flow rate is about 1.05L/min.
🔸600G: Suitable for a family of 6-7, with a flow rate of about 1.58L/min.
🔸800 and 1000G: Suitable for families with a large number of people and who need fast water supply.
Inner filter-RO membrane and activated carbon
The filter element is the core of the water purifier, the RO membrane determines the filtration effect, and the activated carbon determines the taste.
🔸RO membrane: In addition to Dow RO membrane, there are also some foreign brands that are also very good.
🔸Activated carbon: The best is coconut shell charcoal, which makes drinking water sweeter and taste better.
✅Frequently asked questions about water purifiers
❓When should I replace the filter element?
| Inner filter | Replacement | Fineness filtration |
|---|---|---|
| PP | 3-6month | 0.5um |
| ACF | 6-8month | 0.5um |
| ATS | 6-8month | 0.5um |
| CB | 6-8month | 0.5um |
| UF | 8-12month | 0.01um |
| RO | 20-36month | 0.00001um |
Generally, it depends on whether the taste changes and whether the water comes out too fast or too slow. The core can be changed flexibly according to the area of use, water quality, frequency of use, and water consumption.
❓The more filters, the better?
More is not always better, it mainly depends on the quality and type of filter element.
❓How to extend the service life of the filter element?
Install a pre-filter to reduce the burden on the water purifier; some water purifiers come with automatic flushing, which can also remove some impurities.
❓Why does the reverse osmosis water purifier need to be plugged in?
The filtration accuracy of the RO membrane is high, but the tap water pressure is not enough. Plugging in the power can increase the pressure and allow water to pass through the RO membrane.
