This document specifies a method to evaluate the capability of portable household air cleaners to reduce the concentration and viability of key experimentally generated bioaerosols in a specified chamber.

Indoor air free of harmful microbes is important to the health of occupants. This is particularly relevant with regard to increased time spent indoors.

Air cleaners are used to reduce the concentrations of microorganisms in indoor air.

The efficiency of such air cleaners to reduce airborne microorganisms can be assessed in test chambers at controlled air temperature and relative air humidity.

The test is applicable to portable air cleaners commonly used in single room spaces such as those based on mechanical filtration, ultraviolet (UV), ionizers, photocatalytic oxidation, and ozone generators in-unit technology.

If the air cleaner does not claim to have the function of reducing microorganisms, this document may not be applicable unless it is being used to simply evaluate the performance.

This document deals with measurement procedures regarding the reduction of the microbial contamination related to electrical air cleaner appliances for household and similar use.

This document does not apply to appliances intended to be used in medical, veterinary, or pharmaceutical applications.

This document does not address sanitization, disinfection, or sterilization measures.

This document does not support, by itself any health-related claims or conclusions about prevention or treatment of a disease or health improvement.

NOTE 1 IEC 63086-3-1 is created for household and similar electrical air cleaners and is not intended to conflict with or replace standards for commercial or industrial consumers.

NOTE 2 In this document, we do not suggest performance test methods that measure the by-products of either the interaction between microbes or between the air cleaner and the microbes tested in this document. The formation of by-products is an important subject. The subject of measuring by-products is under study, and AHAM will address this in future documents.

NOTE 3 This document does not apply to appliances intended for use in medical treatment locations, such as surgical suites, laboratories, medical treatment rooms, etc.
