The MA-40 Replacement Filter Compatible with Medify manufactured by Midiex is a dedicated two-cartridge set engineered for the Medify MA-40 series, including the MA40W white and MA40B black cabinets. Each rectangular cartridge measures 17 inches in length, 8 inches in width, and 1.77 inches in thickness, matching factory housing slots for a secure friction fit. Its multi-layer construction incorporates an H13 True HEPA pleated stage alongside an activated carbon filter layer.

This cartridge setup fits single-appliance households requiring dependable mechanical particle capture in living areas and bedrooms. Similar to media lifecycles discussed in our levoit self cleaning air purifier maintenance breakdown, regular filter replacement preserves static air pressure and fan efficiency. The three-layer system captures 99.97 percent of suspended particles down to 0.3 microns, arresting pollen, dust mites, and pet dander. At a total package weight of 3.5 pounds for the pair, the pleated assembly resists frame flex during operation.

Midiex rates this medify ma-40 replacement filter for an operational lifespan of 6 to 12 months under nominal conditions. Purchasing this medify ma40 2 pack filter provides a single purifier with up to 24 months of operational coverage before requiring restock.

The Replacement Filter Fit for MA40 Air from EzLfGre is a two-pack replacement designed specifically for MA-40 air purifiers. Built with a rigid plastic perimeter frame, this cartridge incorporates high-grade granular activated carbon to physically adsorb household odors, cooking fumes, wildfire smoke, and volatile organic compounds. While permanent air cleaners like those highlighted in our honeywell permanent filter air purifier overview use washable elements, this disposable cartridge relies on dense pleated media to maximize particulate retention.

This configuration suits households with indoor pets, active kitchens, or residents sensitive to chemical off-gassing. The pleated particulate layer carries a MERV 13 rating and meets the H13 True HEPA standard, capturing 99.97 percent of microscopic irritants down to 0.3 microns, including pet dander, lint fibers, and fine smoke. Although the listing table indicates a product grade of lightly used, each filter ships sealed in airtight plastic to protect the reactive carbon pores from airborne moisture prior to deployment.

Regarding physical dimensions, the listing does not specify the exact length, width, or thickness in inches, designating the unit simply as a rectangular pleated appliance filter for the MA-40 chassis. EzLfGre recommends a filter replacement interval of 6 to 8 months, reflecting a specialized focus on gas-phase and odor adsorption.

• Three-in-one h13 true hepa filter for medify MA-40 series air purifiers
• Granular activated carbon layer targeted at chemical vapors, smoke, and household odors

The cartridge features an integrated three-layer system with pleated H13 True HEPA media and an activated carbon stage, capturing 99.97 percent of particles down to 0.3 microns. Because all four filters feature identical housing tolerances, they seat cleanly against interior sealing gaskets across MA-40, MA40W, and MA40B machines.

Each filter carries a manufacturer service life rating of 6 to 12 months. This four-pack carton delivers up to four years of coverage for an individual appliance or a full year of clean air filtration for four deployed MA-40 units. The total shipping weight is listed at 3.5 pounds.

Smaller rooms and personal workstations often rely on compact purification hardware, and the 25 Replacement Filter Compatible with MA from Cleangela is engineered specifically for the Medify MA-25 platform. Compatible with MA-25 cabinet variants S1, W1, and B1, this package provides four replacement cartridges. The MA-25 employs a dual-sided airflow intake, meaning every filter replacement requires two cartridges installed concurrently on opposite sides of the chassis.

This cleangela ma-25 replacement filter pack fits bedrooms and home offices running the MA-25 air cleaner. As observed with dual-intake systems in our airtok air purifier replacement filter review, keeping both intake ports balanced with fresh media prevents uneven motor strain. Cleangela utilizes a three-in-one configuration comprising an external pre-filter for pet hair and coarse debris, a pleated True HEPA layer trapping 99.97 percent of particles down to 0.3 microns, and an internal activated carbon sheet for ambient room odors.

The listing outlines package dimensions of 14.29 inches in length, 3.14 inches in width, and 25.5 inches in thickness, with a total weight of 1.6 pounds. Cleangela recommends a replacement schedule of 3 to 6 months depending on ambient dust loading, allowing this four-pack to provide two full dual-filter changes.
