Start with your trigger
Chemicals and smoke need heavy activated carbon; allergies and dust need true HEPA. Most of our units do both.
Match it to your space
Coverage is rated in square feet. Size up if you want more air changes per hour in a larger room.
Filtration first, no ozone
No ozone generators and no ionizers. Where a model has a UV-C lamp, it is sealed inside the cabinet and its page says so.
Pick the letter for your problem

True HEPA is rated 99.97% at 0.3 microns. The HEPA Barrier in the C and T series is rated 95% at 1 micron, because those machines are built around the carbon. Prices are ours on October 23, 2026.
Then pick the size
| Series | Room size at 2 air changes an hour | Airflow |
| 400 | About 1,000 sq ft | 353 to 395 CFM |
| 600 | About 2,000 sq ft | 560 CFM |
| 700 | About 2,500 sq ft | 635 CFM |
A 14 on the end (R614, V714) means Super HEPA, rated 99.99% at 0.3 microns. A DLX version changes the carbon stage; each product page lists exactly what it carries. For asthma, smoke or chemical sensitivity, plan on more air changes than two, so size up. The arithmetic is in what size air purifier you need, and the full naming system is in Airpura 400 vs 600 vs 700.
