How about a stainless steel filter?

It depends on the purpose. Like ordinary medium fluid, stainless steel filter has the advantages of anticorrosion and sanitation. If it contains acid and alkali and the temperature is higher than 90℃, it should be lined with fluorine or sprayed with anticorrosion and high temperature resistant materials. The minimum service life of stainless steel filter is 1 to 3 years. If properly maintained and operated, it can be used with 10 for one year.
