After several days of use, I am very pleased with the effectiveness of the Multi-Tech S3000. I've gone from having massive fits of sneezing on a pretty regular basis to only sneezing a couple of times a day. I'm using it on high speed, which does make a fair amount of noise, but the low setting is almost inaudible. The controls are quite simple and intuitive. I can't comment on the cleaning process, as I haven't been running it nearly long enough to justify cleaning the filter. Overall, I find it to be much more effective than any of the filters I have tried in the past.
I brought this product due to my allegies. After one month i still smell no differance in the air quality and i still have the same allegies problems. I turn my machine on at 4pm and when i go to beed at 11pm i put the timer on for 6 hours. I feel the machine is on long enough daily and i should have felt a differance but i do not.
