DISCLAIMER-- I DO NOT WORK FOR A PURIFER COMPANY LOL!! I read this and was like dang, sounds like a door-to-door salesperson! haha
I use the 2 white ones in Noodle's sleep room (pictured below) and I actually use both at the same time (AlenAir and Hathaspace). I used to use the black one (Veva) in another area (and originally liked it) but it broke/got sketchy fast and was only good for a
really small space (plus, it produced a lot of wind and the number of filters it required to keep up ended up costing as much as a nicer model)...
I also use another purifier (also Hathaspace) in the basement, as that is where the furnace/air run through (and yes-- there is still cockatoo dust and the occasional feather in the actual Hepa furnace filter, despite 3 independent purifiers and a Hepa furnace filter lol!)
Anyway, the air quality is still not that great in the house BUT it is LOADS (AND I MEAN LOADDDDS) better than what it was before (the more birds and bodies you have, the more junk that gets in the air)...and then things like new furniture etc also also decrease that quality...The last person who lived here used Glade plug-ins and I washed EVERYTHING (walls included) and these purifiers/filters are the only things that make the air scentless...
If I had to do it again, I'd save my money to buy additional Alen products or something like RabitAir because the mid-line smaller one pictured (HathaSpace) isn't bad, but it isn't accurate in terms of its indicator lights when compared to the AlenAir and it just can't keep up nearly as well (even though it is okay). The thing if someone walks in with perfume on, the Alen turns yellow or red, but the Hathaspace doesn't (stays green) and even at it's max setting, it just can't filter the same amount of air fast enough....Now...if you fart next to it, it freaks out lol, but that is another story...ANYWAY, although it was a lot cheaper, it isn't nearly as good as its job and in a house with 1 bird, I am running 2 at once just to stay in the "moderate" quality zone. In a house w/ 2 cockatoos (plus kids and a potentially sensitive macaw etc), you need something more serious to really catch all of those particles. If there is an ozone/ion/purifier setting on your machine, as long as it can be shut off at all times and doesn't auto-cycle to on, then it is fine.
