When purchasing a filter, a number of factors are taken into account to ensure that the device is selected to meet the specific needs. Here's what to look for when buying a filter:
1. Qualification Certification of a filter
(1) Verify whether the products provided by the manufacturer have the corresponding qualification and certification to ensure the reliability and safety of the products.
(2) Check whether the product has passed the relevant quality testing and certification process, such as ISO certification, to ensure its quality standards.
2. Pressure bearing capacity
Check the maximum pressure the filter can withstand to ensure that it can accommodate pressure relief and avoid damage due to excessive pressure.
3. Technical level of a filter
(1) Understand the technical principle of the filter, such as whether it supports backwashing, that is, whether the impurities on the filter can be thoroughly washed through the internal mechanism.
(2) Consider the filter with high technical content, which can be more effectively cleaned and maintained for long-term use.
4. Material selection of a filter
(1) Evaluate the quality of the filter screen and the main material of the filter, such as whether to use durable stainless steel or nylon filter with reinforced structure.
(2) Select the appropriate material according to the use environment, such as the use of stainless steel or corrosion resistant materials in a more corrosive environment.
5. Easy maintenance of a filter
(1) Consider whether the later maintenance of the filter is convenient, such as whether it is easy to replace the filter element and clean the filter screen.
(2) Choose a filter that is simple to maintain and easy to operate in order to quickly restore its filtering function.
6. Filter effect
(1) Consider whether the filtration accuracy of the filter can meet the needs, such as whether it is necessary to remove small particles or bacteria.
(2) Select the appropriate precision filter according to the results of water quality testing to ensure the desired purification effect.
7. Running cost of a filter
(1) Consider the operating resistance loss of the filter, which will affect the overall energy consumption and efficiency.
(2) Select filters with high energy efficiency and stable operation to reduce long-term operating costs.
8. Applicability
(1) Ensure that the inlet and outlet diameter of the filter matches the pipe in the home to avoid installation problems caused by size mismatch.
(2) Select the appropriate size and capacity of the filter according to the water treatment volume and filtration needs of the home.
9. Corrosion resistance
(1) Especially in the chemical industry, the corrosion resistance of the filter is an important consideration, and the appropriate material should be selected according to the chemical properties of the processed material.
(2) For the occasion of dealing with corrosive liquids, materials with stronger corrosion resistance should be selected.
