The filters carry a MERV 13 rating; in other words, they remove 98% of the particles that are in the air. Among such particles are fine dust, dander, bacteria, smoke, and allergens. Our filters that are designed for families with asthma or allergy problems, go far beyond the standard MERV 8 and 11 options in they are capable of catching even smaller particles without the air flow decrease (low) - this is possible due to the use of our synthetic medium with electrostatic charge and the design of the pleat made with high precision.
