The ONLY reason I am giving the MA-40 Purifier 4 stars is because I wish it had wheels so I can move it to the other side of my home which is a ranch style.


Can you just leave it in one spot and if so, where do you recommend? Middle of the space or or do you have to move it around? Also, if it cleans the space in 30 minutes.. how often do you recommend turning it on... btw, I have all carpeting and a furry cat.. Thank you for the info..
Keep it Away from Walls & on a Flat Surface – Ensure there are no objects blocking airflow, and place it in a dry area with humidity below 85% for optimal efficiency.
Close Doors & Windows – This prevents outside pollutants (like smoke or dust) from entering and ensures the purifier effectively circulates clean air.
Run It Continuously at a Low Speed – Air quality fluctuates throughout the day, so running the unit at high speeds for an hour then 24/7 at a lower speed is the best way to maintain consistently clean air.
Check & Replace Filters Regularly – With carpeting and a furry cat, your filters may collect more dust and dander. Be sure to check them regularly and replace them every 3 to 6 months (or sooner if they appear clogged).
For placement, keeping it in a central, open area (like the living space) is ideal for even air distribution. Let me know if you need any further guidance—I’m happy to help!
