I put this DHLifelabs Sciare mini in my bedroom and it has made a world of difference. I can breathe easier and certainly sleep better. Having an assortment of animals, pet dander has been a problem. Living in the country in the south, there are dirt roads and inches of pollen. I was always having issues with clear breathing. It removes 99%+ of those allergens. It neutralizes odors, which is a huge  benefit for me. It stands 20" tall and 9" wide. Perfect size without being in the way. Very easy to operate and quiet, so it doesn't interfere with my sleep. The 3 stage HEPA  filter is probably the best thing since sliced bread. It captures viruses, allergens, pollutants, dust, pollen, smoke, bacteria and pet dander. A perfect solution to clean, healthy air.
