How Does an Air Purifier Work ?
Air purifiers are designed to help remove airborne particles and odors from air passing through the filter.
How is the Performance of an Air Purifier Measured?
Most air purifiers are tested for efficiency in terms of Clean Air Delivery Rate (CADR).
What it is: CADR is a third party test measure indicating the volume of filtered air delivered by an air purifier. The higher the CADR numbers, the faster the unit filters the air passing through the filter.
Why it is important: CADR is an objective way for you to compare the performance of one air purifier to another.
Tip: CADR values will vary by size of the product. The below information will assist you in purchasing a product with enough cleaning power by room size.
- Small Room (nursery, office or small bedroom) – up to 155 sq ft Recommended CADR: up to 97
- Medium Room (bedroom or family room) – up to 300 sq ft Recommended CADR: 98-130
- Large Room (great rooms or large living spaces) – up to 500 sq ft Recommended CADR: 130 and up
Having the right filter to solve your particular issue, makes all the difference. See below for information on each filtration type based on your specific need.
