Pre Filters & Fine Filters
Pre filters and fine filters – First Line Defense Against Airborne Contaminants
Air filtration begins with the right pre-filters and fine filters. These filters serve as the first line of defence, capturing large and medium-sized particles such as dust, fibres, dander, pollen, insects, and hair before the air reaches high-efficiency HEPA or ULPA filters. By intercepting these contaminants early, pre-filters & fine filters help extend the life of downstream filters, improve airflow efficiency, and reduce system maintenance costs.

Frequently Asked Questions (FAQs)
What’s the difference between a pre-filter and a fine filter?
Pre-filters trap large particles (e.g., insects, lint), while fine filters handle medium-sized particles (e.g., pollen, mold spores).
How often should these filters be replaced?
Depending on the environment, every 3 to 6 months is recommended, or sooner in high-dust settings.
Are these filters compatible with HEPA systems?
Yes, they are typically installed upstream of HEPA or ULPA filters in multi-stage filtration systems.
Can I get them in custom sizes?
Yes, Dyna provides customized filters for OEMs and retrofit needs.
