Within an make an effort to prolong the utilization lifetime of a HEPA, a pre-filter is often A part of the established-up which assists to remove the more substantial particles, leaving the finer-sized particles to generally be caught from the HEPA filter.

HEPA filters exhibit Remarkable capabilities in capturing a wide array of airborne particles, producing them highly efficient in bettering indoor air excellent. Common contaminants eliminated by HEPA filters contain dust, pollen, pet dander, mold spores, and several microorganisms and viruses.

This method commonly offers a large enhancement in performance. You may use cardboard, duct tape, or wood to generate the quilt – some DIY enthusiast designers connect with these “shrouds”. This include can be produced from the cardboard box through which the supporter was packaged, at no supplemental Expense. Enhance the seal wherever the filters are hooked up to the enthusiast or each other. Seal the perimeters employing duct tape, one example is, instead of ties or clamps.
