Filtration Technology
The MSA3S uses a 3-stage filtration system anchored by an H13 True HEPA filter that captures 99.97% of airborne particles at 0.3 microns, including pollen, dust mites, mold spores, and pet dander. A pre-filter handles larger debris like pet hair and dust, extending the life of the HEPA filter, while the activated carbon layer absorbs odors, smoke, cooking smells, and VOCs.
This combination puts it on par with purifiers costing significantly more, and the H13 grade is a step above the standard HEPA found in many entry-level competitors.
Noise & Performance
At its lowest fan speed, the MSA3S produces just 22 dB of noise , quieter than a whisper and well suited for bedrooms and home offices where silence matters. The unit covers up to 1590 sq ft, which is generous for its size and tier class, making it viable for large living rooms and open-concept spaces.
While specific CADR ratings aren't prominently published, customer feedback consistently notes effective air scrubbing and noticeable odor elimination across large rooms.
Smart Features & Controls
The MSA3S connects to your home WiFi network and pairs with the MSPure app for remote control, scheduling, and real-time air quality monitoring from your phone. It also supports Alexa voice commands, letting you adjust settings hands-free.
Auto mode uses the built-in air quality sensor to dynamically adjust fan speed based on real-time readings, and the device displays an AQI indicator so you can see air quality at a glance , a feature that sets it apart from most purifiers in its category.
Filter Maintenance
Membrane Solutions recommends replacing the filter every 6-8 months depending on usage and air quality conditions, with a filter change indicator light on the device alerting you when it's time. The pre-filter captures larger particles first, helping extend the HEPA filter's effective lifespan.
Maintenance is straightforward , the filter compartment is easily accessible, and customers note the device is simple to set up and service without tools.

FAQ
How loud is the Membrane Solutions MSA3S at night?
At its lowest setting, the MSA3S runs at just 22 dB, which is quieter than a whisper and virtually inaudible. Most users report sleeping through the night without noticing it.
Auto mode may increase fan speed if it detects a change in air quality, so switching to sleep mode is recommended for uninterrupted rest.
Does the MSA3S actually remove pet odors?
Yes , the activated carbon filter in the 3-stage system is specifically designed to absorb pet odors, and customers frequently highlight its effectiveness against cat-related smells. The H13 HEPA filter simultaneously captures pet dander and fine hair particles, addressing both odor and allergen concerns.
How do I connect the MSA3S to WiFi and Alexa?
Download the MSPure app, create an account, and follow the in-app pairing instructions to connect the device to your home WiFi network. Once connected, you can link it to Alexa through the Alexa app for voice control.
Note that the purifier requires a 2.4 GHz WiFi network , 5 GHz networks are typically not supported.
How often do I need to replace the filter on the MSA3S?
Membrane Solutions recommends filter replacement every 6-8 months under normal use. The device has a built-in filter change indicator that alerts you when it's time.
Homes with pets, smokers, or high dust levels may need more frequent replacement. The washable pre-filter can be cleaned separately to extend overall filter life.
Can the MSA3S purify air in a large open-concept living space?
The MSA3S is rated for up to 1590 sq ft, which covers most large living rooms and open-concept layouts. For best results, position the unit centrally with clear airflow around it.
In very large or multi-story homes, you may want a second unit to ensure adequate air changes per hour.
What does the auto mode do on the MSA3S air purifier?
Auto mode uses the built-in air quality sensor to continuously monitor your room's air quality and automatically adjusts the fan speed in real time. When the sensor detects elevated particle levels , from cooking, pet activity, or opening windows , it ramps up.
Once the air clears, it dials back to save energy and reduce noise.
