Filtrete air con filters -- I've been doing it wrong?

I fitted Filtrete into my wall-mounted Daikin unit after having the unit cleaned. 

The wall-mounted unit (not the compressor) is quite noisy know.Is this a typical effect of Filtrete? (I have never used Filtrete before)

Or is this an effect of shoddy cleaning? (My Mitsubishi unit got noisy after cleaning,  no Filtrete involved)

They must filter something as they turn dark gray after a couple weeks use...

Fully agree with that. I am using the 3M filters and cover only about 60% of the required area. Within a few days the filter turns from white to grey and black within 2-3 weeks. This black dust would otherwise be in my lungs. I am in Bangkok.

The pm2.5 part of it would not be in your lungs - it passes through the lungs and goes directly into your blood. :wacko:

 

Did the Filtrete make your a/c more noisy?

The filters of 3M are very thin and there is no change in noise level at all.

I would never obstruct the airflow off the air conditioner in any way.
 
We are using the air purifiers from Hatari since I can easily mount a Filtrete in front of the original Hatari filter. Just takes a few minutes. This makes them very cheap to operate in the long run. The actual filter from Hatari I only replace every one or two years.
 
So in our 50 m² lobby we operate three such air purifiers and get down the AQI index down to about between 15 and 25. In my a bit less than 15 m² office I only operate one such purifier and I have an AQI index between zero and 12. The given values applied to outside AQI about 150.
