Filter Units

---

Our filter units have been used for over 20 years as an efficient and effective method for purifying air inside homes and businesses. When used independently, our filter units serve to simply filter the surrounding air. However, because these are the same units used in our NPMRs, they work at a 99.97% rate of efficiency down to .3 microns; providing a sufficient method to help purify air in both public and private residences.

For organizations or individuals that require the use of a positive pressure environment instead of our commonly used negative pressure system, our filter units can be designed to work as such. By simply reversing the direction of airflow through the unit, one is able to create a positive pressure environment that filters clean air into the designated area.
