I guess I should of put it all together but didnt. I had no idea Cape parrots are dusty like African Greys. I noticed when the air in my house felt "heavy". The only new in my household is her. I ran out immediately and bought 2 lg Honeywell hepa's for family room where 3 of my birds live including her - one on either side of room as it is a fairly family room, another lg Honeywell Hepa for living room where my Amazon is, and a small honeywell hepa filter for upstairs hall way. The air doesnt begin to reach either of them. All that dust cant be good for any of us to breathe even her. Hopefully these filters help. Ariel is just perfect in my eyes even if she is a dustball lol
