Doctor of Environmental Toxicology from Murdoch University has evaluated the Filter Queen against many other brands. He states, "As a result of it's superior qualities I now only use Filter Queen in my research. Every time we collect samples of dust we use the Filter Queen because it is highly efficient in removing dust from surfaces and does not decontaminate the air."
