    PuroAir 240

    I love this air purifier. I research most quality puroair and I ended up choosing this one and I am very very pleased. I live close to a cement company and it gets so dusty too often. Using this machine makes dusting wait for at least a week or more without seeing that gray layer of dust!

    Wonderful Addition to the House!

    Our son recently went through a bone marrow transplant, so when he moved home from the hospital we wanted to make sure the house was a healthy environment for him. So to be safe, we ordered one 400 model and 2 240 models. We have been so happy with them. They are quiet and clearly they are working! It brings us peace of mind while our son continues to heal ❤️
