The Honeywell HPA200 True HEPA Allergen Remover Air Purifier is an amazing air cleaner for large sized rooms that uses 4 air cleaning levels-- Germ, General Clean, Allergen and Turbo-- to clean the air in your home as these can aggravate your respiratory system and pollute your household.
Not only is this good for purifying the air in your home, it also is energy efficient and has easy to maintain replacement filters -- these will need to be changed every three months, depending on usage, but there is a filter light that will guide you on when to change them!
In Chapter 8 of the Dog Cancer Survival Guide, Dr. Dressler discusses the impact that carcinogens in the air have.
