What Is the link between CADR ratings and air purifiers? What is the 28 cubic meter purifier test chamber?

One-quarter of their time, There's a revised version of air purifiers that are available on the market, but the efficiency and performances that they generate are usually measured through CADR.

 

CADR which is usually measured through CFM shows how efficiently particles from a particular room are filtered out. In  most cases, dust, pollen,  and other particles can cause respiratory problems if they reach a density of 150 CFM onwards if they are not properly  filtered out.

 

How do you measure the CADR level? This requires the use of a 28-cubic meter purifier test chamber

 

According to ANSI/AHAM AC-1-2006, a unified and repeatable standard method for air purifiers is established to measure the performance of portable household air purifiers. This laboratory can test smoke particles (second-hand smoke, corresponding to national standard solid pollutants) dust and pollen. Do not test for gaseous contaminants.

The tested purifier models include: floor type, desktop type and wall hanging type.

Test items: CADR value, laboratory temperature, relative humidity, purifier current, voltage, power and other items
