30 cubic CADR test chamber teaches you to distinguish good or bad air purifier

Now the market air purifier is unlimited hype, the price song varies. Countless rich businesses into the air purification industry, of course, the products made also vary.

  To make indoor air quality to a certain standard of cleanliness, air purifiers have two necessary hard indicators, 1, than must ensure that the indoor air to a certain number of air changes (international is 5 times); 2, air purifier than a purification efficiency must be relatively high. If indoor pollution sources continue to generate, these two hard indicators of air purification machine can keep indoor pollutants at a lower concentration.

Thus, it seems that although there are so many such and such air purification products on the market, but as long as these two conditions are used to measure, like a demon mirror, the real fake ones are out.

30 cubic meters of your CADR test bin test method.

1. based on: the standard ANSI/AHAM AC-1 test procedures and calculation formula.

2. Test chamber volume: 10 ½ ft. x 12 ft. x 8 ft= 1008ft3.

3. Instrument used: Laser particle counter. 4.

4. Test environment: temperature: 25±1.5℃, ambient temperature: 40±5 percent

5. Test procedure:

a) Clean the test chamber with an auxiliary purifier.

b) Inject cigarette smoke, while stirring with a fan to make a uniform distribution of smoke and dust.

c) Turn on the sample machine to be tested, while the laser particle counter starts sampling and recording.

d) The recording period is: 2 minutes to sample and record once.

e) End of sampling and recording after 10 times

f) Calculate the CADR value using the data recorded in these 10 sets.

6. Calculation formula: CADR = V(ke - kn)

V= volume of test chaMber, cu. ft.

ke= measured decay rate, min-1

kn = natural decay rate, min-1
