What is Microfiltration?

Microfiltration is a membrane filtration technology used to reduce particles and microorganisms from water. It is commonly used as a final point-of-use filtration stage in laboratory water systems.

Microfilters are often installed near the dispensing point to ensure that water remains protected after passing through the purification system.

What does Microfiltration remove?

Microfiltration helps reduce:

  • Particles
  • Fine suspended matter
  • Some bacteria
  • Microorganisms larger than the filter pore size

Typical final filters may have pore ratings such as 0.2 µm, depending on application requirements.

How does Microfiltration work?

Water passes through a membrane filter with controlled pore size. Particles and microorganisms larger than the pores are retained, while water passes through.

Because microfiltration is a physical barrier, filter integrity, replacement frequency and sanitary handling are important.

Why is Microfiltration important?

Even if water is purified, contamination can occur in tubing, storage tanks, fittings or dispensing points. A final microfilter provides last-stage protection before water is used.

This is important for analytical instruments, reagent preparation and applications where particulate contamination must be minimized.

Typical applications

Microfiltration is used in:

  • Final point-of-use filtration
  • HPLC water dispensing
  • General laboratory water dispensing
  • Protection of sensitive instruments
  • Particle-sensitive applications
  • Final polishing outlets
