Overview
A home with a large living area and a main bedroom gets one Medify purifier for each, sharing the same fine grade HEPA filter and UV light. Touch controls set three fan speeds, a timer, sleep mode and a child lock.
Two units let you treat separate rooms at once rather than moving one around. Filter changes come up several times a year per unit, so ongoing upkeep doubles too.
Who it's for
Homes with pets, allergy sufferers or wildfire smoke across more than one room will use both units. Those needing quiet at full power should note the top speed noise.
Pros and cons
- Two units for two rooms
- H14 HEPA captures very fine particles
- Child lock for kids and pets
- Sleep mode dims panel lights
- Filters need frequent replacement
- Loud at the highest speed
- Coverage claim differs in title
Performance notes
Room cleaning speed follows the CADR, which measures clean air delivered at the top fan setting. Lower speeds are quieter but move less air, so a large room clears more slowly at night settings.
