I had to start a new account under ilovemacaws1 as i used to be called ilovemacaws but changed my email address and forgot my parrot link password!. My problem is this, I have a ducorps (foofoo) who has gout and is producing a HELL of a lot of dust, this seems to be irritating the greys, macaws and the dog, as well as me!! I have laminate on the floor and damp dust daily, but cant seem to stay on top of the dust he creates, its like a bag of flour has been opened in the room every day, bit dramatic i know but thats what it feels like! I bought a HF380 (http://www.heavenfresh.co.uk/index.php/naturopure-air-purifiers/hf380) and i dont know if i had a duff unit or not, but it seemed to make the problem worse. I itched worse from the dust and the allergen light never came on, only the odour light when i opened the door momentarily from when i had been smoking in another room. The other birds seemed to be affected by it too, itching and pulling feathers. I have read that you shouldnt use an ioniser around birds and was wondering if that is the problem with this unit and if anyone has any advice as to a good air purifier. I currently have an airfree p60 in front of the cage but that seems ineffective too. Help please?
