Medify Air MA-40 Replacement 3-in-1 Filter — 1-Pack HEPA H14 + Activated Carbon, Pre-filter

Replacement Medify MA-40 3-in-1 filter combines a washable pre-filter, a True HEPA H14 layer, and activated carbon to reduce dust, smoke, pollen, pet dander and common household odors.

Keep your MA-40 air purifier performing at peak efficiency with this genuine Medify Air 1-pack replacement filter. Engineered for the MA-40 unit, the cartridge uses a three-stage system designed to trap large particles, capture microscopic contaminants down to 0.1 microns, and absorb volatile odors. Regular swaps restore airflow and purification power so rooms stay fresher and indoor air quality remains consistent.

How long will one MA-40 replacement filter last?

Under normal residential use, each genuine Medify MA-40 filter runs up to about 3,000 hours—roughly 4 to 5 months—before performance declines. Actual life depends on pollutant levels, run time and environment; heavy smoke or continual pet hair will shorten service life.

• Estimated lifespan: ~3,000 hours (4–5 months typical)
• High-pollution environments require more frequent changes
• Check filter indicator on your MA-40 for replacement prompts

What does the 3-in-1 filtration include and how does it help?

The filter integrates a pre-filter, True HEPA H14 media, and an activated carbon layer to address particles, microscopic contaminants and odors in one cartridge. Each layer has a focused role so the purifier removes visible dust and hair, traps submicron particles, and reduces cooking, smoke and pet smells.

• Pre-filter catches large debris and extends HEPA life
• HEPA H14 captures up to 99.99% of particles down to 0.1 microns
• Activated carbon adsorbs gases and common household odors

Is this filter easy to install and maintain?

Yes—filters are designed for straightforward replacement with no tools required. Removing the old cartridge and snapping the new filter into the MA-40 housing restores performance; occasionally vacuum the pre-filter area to reduce heavy surface dust before installing the new unit.

• Tool-free installation for quick swaps
• Follow MA-40 indicator or schedule for best results
• Light vacuuming of the pre-filter area can help extend life

Will a genuine Medify filter perform better than third-party alternatives?

Genuine Medify MA-40 filters are manufactured to meet the purifier’s specifications for fit, airflow and filtration efficiency. Using an OEM cartridge helps maintain rated filtration performance and reduces the chance of gaps or airflow restrictions that can occur with mismatched replacements.

• Made to fit the MA-40 housing precisely
• Preserves stated HEPA H14 efficiency and airflow
• One-pack option keeps spare filters on hand for timely changes

Who is this for: Homeowners, pet owners, or anyone using a Medify MA-40 who wants dependable air cleaning without fuss. This 1-pack replacement is ideal for small to medium rooms where regular filtration is needed to manage dust, pollen, smoke residue and everyday odors—especially for those who prefer using genuine Medify components to preserve purifier performance.
