xKeep your MA Series air purifier performing at its best
Introducing KeeTidy's 4 Pack Model 15 replacement filters, designed for compatibility with MA Series Air Purifiers (S1/W1). Each filter measures 9.75" x 5.125" x 1", and the four-pack design makes maintenance straightforward and economical.
Three-stage filtration for clearer indoor air
- First layer – Pre-filter: Saturated polyester traps dust, hair, and larger debris, helping pre-treat air and extend the life of inner layers.
- Middle layer – H13 true filtration: Electrostatic filter paper captures very fine particles as small as 0.1 microns with high efficiency.
- Third layer – Activated carbon: Coconut shell carbon reduces odors and formaldehyde, giving air a fresher feel.
Why replace regularly
Filters can degrade over time or under heavy use. We recommend replacing every 3–4 months or when your purifier’s replacement cartridge light turns red. Regular replacement helps maintain performance and minimize secondary pollution risks.
Real-life scenarios where KeeTidy helps
- Living with pets or in shared spaces where dust and dander accumulate.
- Kitchens or dining areas where cooking smells linger.
- Urban apartments with higher particulate matter and off-gassing from furnishings.

Easy to install, easy to maintain
Designed for a seamless fit with the MA Series 15 S1/W1 units, this 3-in-1 filter replaces the existing cartridge with minimal effort. The sturdy pre-filter extends service life, while the H13 and carbon layers work together to refresh the air between replacements.
