Bests & Worsts Reviews from Amazon

Very disappointed. Our MA-40 is now on its sixth new Medify brand filter set which are changed out about every six months. We have meticulously cleaned our unit about every 2 months per Medify instructions including the sensor. Since replacing the original filter set using Medify’s brand, our unit has NEVER been able to achieve “green light status” indicating that the Medify MA-40 has “filtered” the air to “good quality”. Support suggested that the sensor may not be clean though we have certainly cleaned it as instructed with a-tips. Today, I thoroughly cleaned our unit and replaced the used filter with a new Medify brand filter set. As expected, upon turning the unit back on and resetting the “replace filter” warning light, the “green lights” glowed for about three seconds before going “red”. In Auto Mode, the default mode, if the system is “filtering” with “red lights” glowing, it is excessively loud and annoying. When the system is working properly and kicks in to this mode, it generally lasts a few minutes before ramping the system back down to “normal” and thw fan to a much quieter mode. For over two years now, we have been forced to operate this unit in manual mode keeping the fan at a tolerable sound level. The “red lights” on the unit, indicating “bad air quality” remain constantly “ON”. Thus, our Medify MA-40 is serving no use in providing the air quality we expected. We were quite exited in the beginning and felt we made a smart, healthful purchase. Very disappointed now. Buyer beware.
