About this item
Product details
A Walmart-exclusive offer, the MA-25 Value Pack Bundle includes a free replacement filter ($39.99 value) that adds up to 4 months of filter life. Every package comes with the bestselling MA-25 air purifier with one True HEPA H13 filter inside, and an extra replacement filter for FREE. The MA-25 Air Purifier blends style, and technology, and quality long-term air cleaning. Its high grade HEPA filter cleans the air in a room up to 825 square feet in 1 hour, 413 square feet in 30 minutes, and 206 square feet in 15 minutes making them a perfect fit for your office, living spaces or bedroom. With 3 fan speeds, timer, night mode, and child lock you can be rest assured this filtration system has you covered. The first line of defense in this portable air purifier is the pre-filter which removes hair, fibers, and large particles like dander. Next, the high-efficiency HEPA filter ensnares pollen, dust mites, and other tiny airborne particles you can't see down to 0.1 microns in size. The last layer of filtration is the carbon filter removing odors and smoke from the air in your living space. Inspired by parents who wanted to provide relief to their daughters suffering from asthma, Medify Air purifiers were engineered from the start with top-quality True HEPA H13 filters. Flash forward, and Medify has now helped countless schools, medical offices, and individuals create safe environments with ultra-clean air. We offer solutions that are long-lasting, powerful, yet simple to use.
