us mark hvac-filters 2Only the asthma & allergy friendly™ Certification Standard ASP-08-03/101 for HVAC/ furnace filters is specifically designed to address allergen related capture regardless of the particle size at which it is found.

The asthma & allergy friendly™ Certification Mark is awarded only to those media based HVAC/furnace filter products that can be scientifically demonstrated, when in use, to capture specified levels of various sized allergen-bearing particles as determined by airborne measurements pre and post filtration at levels as follows:


% Reduction

Timothy Grass Pollen (Phl p 5) (12 – 100 μm)


House Dust Mite (HDM) Allergen (Der p 1) (3 – 20 μm)


Cat Allergen (Fel d 1) (1 – 20 μm)


Micro Particles (0.3 – 1.0 μm)


*In selecting these particular allergens, it is recognized that cat allergen (Fel d 1) associated particles are equivalent in size to those of dog and rodent dander, Timothy grass pollen (Phl p 5) is equivalent in size to other pollens (ragweed, trees etc.) and HDM allergen (Der p 1) is equivalent in size to mold spores and cockroach allergen.

The use of Certified HVAC/furnace filters does not replace source control in an overall allergy action plan. Optimal indoor air quality represents a central aspect of the management of asthma and allergic diseases and as such a Certified HVAC/furnace filter is likely to contribute to such optimization.

The rating system currently employed by the HVAC/Furnace Filter Industry, termed MERV (Minimum Efficiency Reporting Values), addresses the ability of a filter to capture particles of predetermined size. The dust utilized is ASHRAE Test Dust, a blend of 72% standardized fine test dust (sometimes referred to as Arizona Road Dust), 23% powdered carbon and 5% milled cotton linters, and potassium chloride (KCl). Unfortunately such assessments do not adequately address the fact that allergen associated particles and size vary greatly between specific allergens and for specific allergens.  For example dust mite associated allergens can vary between 5 and 20 μm with cat allergen can be found in particles as small as 0.5 μm and up to 3 μm and above.
