I have found a product which helps in removing odors from your household, it work fine in your home. First, a prefilter and a charcoal filter combine to capture large particles like dust, smokes, cooking odor. A true hepa filter capture 99.97% of airborne particles as small as microns in size, such as dust mite, debris, mold spores, plant pollens, and pet dander. American doctors recommend this hepa air filtration system to reduce exposure to indoor asthma triggers. It kill airborne viruses and bacteria, it has UV_C light which kills bacteria and viruses including rhinovirus, ecoli, and streptococcus. The UV-C light sanitizes by permanently damaging the DNA of germs so they die. If you are in nigeria, you are unlucky to have this product that do this job very fine but the good news is, if you have some one in the U.S, you can get it.
