The Medify Air MA-22 Air Purifier is designed to remove airborne contaminants from indoor air, providing a higher standard of air purification. It utilizes a genuine Medify True HEPA H13 Filtration System, which is a multi-stage filtration process to ensure comprehensive air cleaning.
Function Description:
The primary function of the MA-22 is to purify indoor air by capturing various airborne particles and reducing odors and volatile organic compounds (VOCs). The filtration system consists of three main stages:
- Pre-filter: This initial layer is designed to capture larger particles such as hair, fibers, and pet dander, preventing them from clogging the subsequent filters and extending their lifespan.
- True HEPA H13 Filter: This high-efficiency filter is tested to remove up to 99.9% of airborne particles as small as 0.1 microns. This includes common allergens like pollen, dust, dust mites, germs, pet dander, mold spores, and smoke particles. The H13 grade HEPA filter is a higher standard, ensuring effective capture of even microscopic particles.
- Activated Carbon Filter: This substantial carbon filter, containing carbon pellets, is crucial for absorbing and eliminating toxic odors, smoke, and formaldehyde from the air. It targets gaseous pollutants that other filters might miss.
The air purifier operates by drawing in ambient air, passing it through these three filter layers, and then releasing cleaner air back into the room.

- Child Lock Function: To prevent accidental changes to settings, a child lock can be activated by pressing and holding the designated button for 3 seconds. The same action deactivates it.
- Placement: For optimal performance, the air purifier should be placed in a dry location on a flat surface. It is important to ensure that air intake and outlet are not obstructed. A minimum distance of 20 inches (50 cm) from walls or furniture is recommended to ensure sufficient air circulation and high efficiency.
- Standby Mode: When the unit is plugged into a power source, it enters standby mode after one second, indicated by the unit lights turning on briefly.
Maintenance Features:
Regular maintenance is essential for the MA-22 to ensure its longevity and continued effective performance.
- Filter Replacement Indicator: The unit is equipped with a light indicator that illuminates when it's time to replace the True HEPA H13 filter, based on the air purifier's hours of use. The suggested frequency for filter replacement is every 3-4 months or after 2,500 hours of use, whichever comes first.
- Filter Replacement Process:
- Place the machine in a dry location on a flat surface.
- Rotate the base clockwise to unlock it.
- Pull the base downwards to reveal the filters.
- Remove the old filter for cleaning or replacement.
- Crucially, all plastic packaging must be removed from the new filters before installation.
- Insert the new filters.
- Re-attach the base by rotating it counter-clockwise to secure it.
- The unit should never be run without filters installed.
- Cleaning the Air Purifier:
- Always unplug the unit before cleaning.
- Do not immerse the machine in water or any other liquid.
- Avoid using abrasive, corrosive, or flammable products for cleaning.
- Use a soft and dry cloth to remove dust from the exterior of the air purifier, including the outlet and inlet.
- The composite filters cannot be washed. While surface-level dust can be removed from the filters using a brush or dust collector, avoid pressing hard on the filter material.
- Long Time Idling: If the unit will not be used for an extended period, unplug it and store it in a dry, well-ventilated place.
