Medify Air MA-25 Replacement Filter Set 1-Pack — 3‑Stage Pre-filter, True HEPA H13 & Activated Carbon for Allergens & Odors

Genuine Medify Air MA-25 replacement filter (1-pack) is a three-stage filter—pre-filter, True HEPA H13, and activated carbon—designed to fit the MA-25 purifier and capture particles down to 0.3 microns.

Keep your Medify MA-25 operating at peak performance with an authentic replacement filter engineered for consistent airflow and reliable particle removal. This three-layer cartridge combines a washable pre-filter for large debris, a lab-tested True HEPA H13 element for ultrafine particles, and activated carbon to reduce smells and volatile compounds. Replacing the filter on schedule restores CADR efficiency and helps the purifier maintain quiet, energy-efficient operation in bedrooms, offices, and living spaces.

How does this filter improve indoor air quality?

The MA-25 replacement filter uses a staged approach to trap contaminants of different sizes. Large particles are caught in the pre-filter, microscopic pollutants are captured by the HEPA H13 layer, and odors or gaseous compounds are adsorbed by activated carbon. Together they lower airborne irritants and reduce lingering smells without altering your purifier's original airflow design.

• True HEPA H13 tested to remove most particles in the 0.1–0.3 µm range by independent labs.
• Pre-filter extends HEPA life by capturing hair, lint, and larger dust.
• Activated carbon targets household odors, smoke, and VOCs.

How often should I replace the MA-25 filter?

Filter life depends on usage patterns and indoor pollution levels, but typical continuous operation yields several months of effective service. Expect up to roughly 2,500 operating hours—commonly 3–4 months in everyday home use—before performance declines. Check your purifier's indicator or inspect the filter visually for heavy soiling and odors as practical guides.

• Estimated life: about 2,500 hours or approximately 3–4 months under normal conditions.
• Replace sooner in smoky, pet-heavy, or highly dusty environments.
• Use the purifier’s indicator light or visual inspection to confirm replacement timing.

Is this filter compatible with my unit and easy to install?

This cartridge is manufactured specifically for the Medify MA-25 model and is intended to replace the original filter set without modification. Installation is straightforward: open the rear filter access, remove the old cartridge, insert the genuine replacement, and reset the unit according to the MA-25 manual. Using a genuine Medify filter helps ensure proper fit and avoids possible damage from non‑compatible alternatives.

• Designed exclusively for the Medify MA-25 air purifier.
• Tool-free swap: remove old filter, seat new cartridge, reset filter timer.
• Genuine design preserves airflow path and sealing for optimal filtration.

What performance can I expect for allergies, smoke, and pet dander?

The combination of True HEPA H13 and activated carbon offers broad performance across airborne particulates and odors. HEPA captures pollen, dust mite particles, and pet dander, while the carbon layer helps minimize smoke smell and volatile odors. This makes the filter a practical replacement for homes with seasonal allergies, indoor smokers, or pets.

• HEPA H13 reduces fine allergens and particulate matter commonly linked to irritation.
• Carbon layer lowers smells from cooking, pets, and mild smoke events.
• Pre-filter reduces clogging and prolongs the HEPA element’s effectiveness.

It suits households with allergy sufferers, pet owners, light smokers, or anyone seeking better indoor air quality without altering their purifier.
