With the increasing demand for water quality, whole house water purifiers have gradually become a necessity in family life. However, there are a variety of whole house water purifier brands and models on the market, how can you choose the right whole house water purifier for your family? In this article, we will analyse the principle of water purification, cartridge material, use effect and price to help people make a wise choice.
Firstly, the core function of a whole house water purifier is to remove impurities and pollutants from water by purifying the water source. There are currently three main water purification principles on the market, including activated carbon adsorption, ultrafiltration and reverse osmosis.
1. Activated carbon adsorption: activated carbon has a strong adsorption capacity and can effectively remove organic matter, odour and colour from water. However, activated carbon adsorption has a limited effect on the removal of inorganic substances such as heavy metal ions.
2. Ultra-filtration: Ultra-filtration is to filter the impurities in water through the cartridge with smaller pore size, which can remove particles, bacteria and viruses in water. However, for dissolved substances such as calcium and magnesium can not be removed, but also will be the water minerals and filtered out.
3. reverse osmosis: reverse osmosis using the characteristics of semi-permeable membrane, through the water pressure difference will be separated out of the solute in the water, can remove most of the dissolved matter and bacteria. However, reverse osmosis equipment is relatively large, the price is also higher.
On balance, if the family water source is relatively clean and the main problem is particulate matter and bacteria in the water quality, etc., then choosing an ultrafiltration type whole house water purifier is more suitable. If the water quality contains more dissolved substances such as heavy metal ions and minerals, or the family has higher water quality requirements, you can consider choosing the reverse osmosis type of whole house water purifier.
Secondly, the cartridge material is one of the key factors affecting the performance of the whole house water purifier. Currently on the market, common filter materials include activated carbon, ceramic, fibre, polymer and semi-permeable membrane.
1. activated carbon: activated carbon has a strong adsorption capacity and can remove organic matter and odour from water. However, it requires regular replacement of the filter element, and the cost is high.
2. ceramic: ceramic cartridge can effectively filter particles and bacteria in the water, and the service life is longer. But for the removal of dissolved substances is less effective.
3. Fibre: Fibre cartridge can filter particles and bacteria in the water, and has a longer service life. But for the removal of dissolved substances is poor.
4. polymer: polymer cartridge has better filtration effect, can remove particles and bacteria. But the durability and service life is relatively short.
5. semi-permeable membrane: semi-permeable membrane has better filtration effect, can remove bacteria, dissolved matter and heavy metal ions. However, they are more expensive and need to be replaced regularly.
On the whole, if the main problem of the family is the particles and bacteria in the water quality, etc., you can choose ceramic or fibre cartridge; if the water quality contains more dissolved matter such as heavy metal ions, you can choose semi-permeable membrane cartridge.
In addition, the use effect of whole house water purifier is also one of the important factors to consider. The use effect includes filtration speed, filtration efficiency and water quality improvement.
1. Filtration speed: filtration speed refers to the amount of water that can be filtered per unit of time by the whole-house water purifier. Generally speaking, the faster the filtration speed, the better the experience.
2. Filtration efficiency: filtration efficiency refers to the ability of the whole house water purifier to remove impurities and pollutants. The higher the filtration efficiency, the better the usage effect.
3. degree of water quality improvement: the degree of water quality improvement refers to the whole house water purifier after filtration, whether the impurities and pollutants in the water is significantly reduced. The better the degree of water quality improvement, the higher the safety of home use.
Price is also an important factor to consider when choosing the right whole house water purifier for your home. The price of a whole house water purifier varies depending on the brand, model and function. Generally speaking, reverse osmosis whole house water purifiers are more expensive, while ultrafiltration whole house water purifiers are relatively less expensive.
To sum up, choosing a whole-house water purifier suitable for family use needs to consider the principle of water purification, filter material, use effect and price and other factors. Before purchasing, you can make a wise choice according to the actual needs of the family and the budget, to ensure that the whole house water purifier can provide high quality drinking water and living water to a certain extent.
