- How much room can one unit really clean?
- Realistically a bedroom or medium room. The 125 CFM CADR is low for the claimed 740 sq ft, so large open spaces will not get many air changes per hour.
- Does the UV-C light actually kill germs?
- It shines on the air passing through the unit, so it only affects what crosses the light. Treat it as a supplement to the HEPA filter, not a room-wide sanitizer.
- How often do filters and bulbs need replacing?
- The carbon pre-filter typically lasts a few months, the HEPA filter about six to eight months, and the UV bulb roughly a year, depending on use.
- Is it quiet enough for a bedroom?
- On the low setting, yes for most people. On high it reaches about 55 dB, which is noticeable at night.
- What comes in the two-pack?
- Two complete purifier towers. Check that each unit ships with its HEPA filter, carbon pre-filter and UV bulb installed, since some listings sell filters separately.
- Does it help with pet allergies?
- Yes, the HEPA layer captures dander and the carbon layer reduces odor. Run it continuously in the room where the pet spends most time.
