Pro M (PROMK120PAW)

I have four BlueAir units. I bought the first one in 2020, and they haven't stopped working a single day since. I live in Jakarta, and I have plenty of proof to verify their quality. Mine are ProL, ProM, Classic 402, and BluePure. I like to keep them oversized so I can keep them running at the lowest possible speed. I don't have much experience with other brands, but I think BlueAir units with quality certifications are a good buy. I have allergies and asthma.

I also have a couple of BlueAir and the scheduling feature for smart purifiers is very nice to have. I have it set to run on the lowest fan setting all the time which is so quiet it's undetectable, and ramp it up for a few hours in the afternoon right before we get home from work.

The replacement filters cost too much and hold only 4ish months

I bought the shark never change as my first purifier just recently and I feel the difference with my allergies. The 5 year filter change really attracted me but after reading here a little more I might need to change it more frequently. I also tried the blue air for my office but didn't like it, I didn't feel any difference and it was noisy, I returned it and got the smaller shark never change .

I also really like Blue Air and mine are all 6+ years old at this point.
