    Questions and answers

    Is the MA-40 good for a large room?
    Yes. It is rated at 406 CADR and listed for up to 1,793 square feet, which suits open living areas. Smaller bedrooms will clean faster at lower fan speeds.
    Does it produce ozone?
    No. Medify lists it as ozone-free, and the ionizer can be switched off if you prefer to run HEPA filtration alone.
    How often do filters need changing?
    Medify recommends replacing the HEPA filter roughly every 3,000 hours, or about every four to five months with constant use. The unit has a filter change indicator.
    Is $249.99 a good price?
    It is near the recent high of $245.99 and well above the $140.32 low from October 31, 2026. If you are not in a hurry, waiting for a drop toward the low end is reasonable.
    What comes in the box?
    The purifier ships with one H13 HEPA filter installed, plus a user manual. Replacement filters are sold separately.
