The filter elements for reverse osmosis protection filters are made of stainless steel. Does anyone have experience using them? Are they effective?

What is the filtration precision? How many filter elements are needed? If the quantity is small, disposable filter elements can be used; for larger quantities, stainless steel filter elements may be considered. However, high-precision filter elements require cleaning tools for cleaning, their lifespan is only a few years, and they are expensive
Stainless steel filter elements also need to be replaced. Even after being cleaned several times using an ultrasonic cleaner, these elements become unusable as their pores get clogged. If wedge-shaped mesh filter elements are used, they can be reused, but their precision is not high
It’s such a waste. Using stainless steel not only results in higher costs but also higher maintenance expenses; moreover, improper maintenance will shorten its lifespan.
Reply to 3# zhjumitian: Yes, abroad they can only achieve 15 microns, and the porosity is very low
I’ve never used filter elements made of stainless steel; they are likely to be very expensive, and it’s difficult to ensure consistent filtration accuracy. I don’t recommend them. For regular safety filters, it’s best to use ordinary PP filter elements. If the pre-treatment is done properly, the filter elements can be replaced every 3–6 months, resulting in acceptable operating costs.
Beijing Sifang Dingtai Environmental Protection Technology Co., Ltd. hopes you will take a look at the sintered metal filters.
We use paper filters for the security filters in our equipment; we have never used stainless steel filter elements. The manufacturer told us that they are expensive and troublesome to use, so paper filters are more convenient. Replace it after 2–3 months of use. The operating cost is not high. It’s just my opinion.
Sinter the filter element using 316L or titanium alloy metal powder
Ask the manufacturer for a few to try out; it’s free anyway.
