Applying SHIELD to HVAC System Air Filters can dramatically increase their utility, value, and filtration capabilities, while enhancing the Indoor Air Quality (“IAQ”) in the spaces they service. 

SHIELD is a microbiostatic agent which, upon application, imparts highly durable bacteriostatic, fungistatic, and algaestatic properties into air filter media, creating an invisible antimicrobial barrier that inhibits the growth of microorganisms and helps prevent the growth and spread of bacteria for up to 3 months. SHIELD also suppresses system odors, helps prevent their return, and further elevates Indoor Air Quality by inhibiting the growth of odor
causing bacteria, mold, fungi, algae, and other microorganisms.

Ready-to-use as delivered, and formulated for simple, one-step, “Spray-and-Walk-Away” applications,  SHIELD is remarkably easy to apply, simply spray on both sides of a new air filter, allow to dry, and install the newly treated filter as usual.  Multi-surface SHIELD is effective on all types of air conditioning, furnace, automotive cabin air, and air purifier filters; as well as filter grilles and housings, air handlers, ducting, and related system component surfaces.

Because SHIELD contains no harsh or hazardous chemicals or other adverse ingredients, it’s EPA rated “Category IV” for toxicity, the very lowest toxicity rating any antimicrobial product can be awarded, and one that means no gloves, masks or other Personal Protection Equipment are necessary when applying it, and no Precautionary Statements or Hazard Warnings are required on its labels.

SHIELD is also waterproof, weatherproof, colorless, odorless, non-flammable, non-abrasive, non-corrosive, non-staining, harmless to almost every type of surface and material, dries quickly and invisibly with no fumes or odors, leaves no sticky residue, doesn’t wear off or wear out with normal system operation or maintenance, and a single application lasts and remains antimicrobially effective, helping to ensure treated surfaces and components remain clean, and free of bacteria, mold, fungi, algae, and other microorganisms and odors for up to 3 months, making it an ideal solution for enhancing and protecting Indoor Air Quality.
