I watch all kinds of lovely little critters in my pet sitting business. Actually, just Last year I had a cat, 2 cats, a silly ferret, as well as a guinea pig in my house. if I am not careful, my house easily can get pretty odory with animal dust. I keep all of the cages cleaned but no matter what I do, it seems like my house odors love a barnyard at times. While looking up what to do about it online the other day, I came across a heating as well as air conditioner website. They say that using carbon pre-filters in your Heating as well as A/C system to help with animal odors. These filters are thin as well as you put them directly in front of your official heating or air conditioner filter. They are made mostly of activated carbon as well as the carbon gets rid of the odors. Additionally, you can easily update these carbon filters as often as you would appreciate to without creating much of a footprint. The heating as well as air conditioner website in question even had a coupon to get 50% off if you order these pre- air filters from them. Of course, you have to sign up to have the filters delivered to your mailbox every month. I found the pre-filters to be rather interesting when I saw them but I also love the whole cabin media air cleaners that they offer too. These huge filtration systems hook up to your existing Heating as well as A/C ductwork and properly filter the air for your whole cabin as well as keep it clean.
