HEPA Filter VS ULPA Filter

Filson high-efficiency particulate air (HEPA) and Filson ultra-low particulate air (ULPA) filter are two common air filter in environments that have demanding requirements. Although, both of them are used to eliminate small particulates, there are still small differences between them.

One key difference is the size of particles they can eliminate. HEPA filter can remove up to 99.97% of contaminants as small as 0.3 microns in diameter, and ULPA filter can remove 99.99% of particulates as fine as 0.12 microns or larger in diameter.

A second difference is airflow capacity. As the filter media of the ULPA filter is denser and more compact, airflow is 20% to 50% lower than that in the HEPA filter at the same dimensions.

The third different is price. ULPA filter costs more than HEPA. The last is the lifespan, ULPA filter lasts about 5 to 8 years while the HEPA filter lasts for 10 years.


Why Choose Filson ULPA Filter

Combining quality filter media with a robust frame structure, Filson ULPA filter enjoys a high filtration efficiency of up to 99.99% at 0.12 microns, which can greatly improve air quality and inhibit the growth of bacteria and viruses.

With a pleated and dense design, Filson ULPA filter delivers a larger surface area while allowing air to flow freely, hence it can provide high-performance protection for critical environments. In addition, using the lowest-resistance media, it saves operation costs.

ULPA Filter FAQ Guide

Is ULPA Filter Better Than HEPA?

Of course. Filson ULPA filter is better than HEPA filter, as it can trap more and smaller particulates than HEPA filter. But HEPA filter is a cost-effective solution compared to ULPA filter.

Does Higher MERV Restrict Air Flow?

A higher MERV rating means a higher resistance to airflow. Since higher MERV needs denser filter media, which restricts airflow. Compared to HEPA filters, ULPA filter has almost 50% to 80% lower airflow.

What is the Efficiency and Accuracy of ULPA filter?

In general, the ULPA filter is specially designed to remove 0.12 microns of contaminants at 99.9995% efficiency.

Is ULPA Filter Disposable?

Yes. Filson ULPA filter is disposable. It is really helpful as it saves manual labor to clean. It has a simple structure and light weight for easy replacement. What’s more, its larger dust-holding capacity also prolongs its lifespan.
