Below you will see a great top tips for free dust
Ditch your carpeting: In most home carpet is by far the biggest dust reservoir. It’s a huge source of fibers and absorbs dust like a giant sponge. Even the padding underneath holds dust which goes airborne with each footstep. Although ripping out your wall to wall carpet may sound radical, it’s the best think that you can do if you suffer from serious allergies. Replace carpeting with hard flooring like laminate, wood or tile and wet mop it regulaly with microfiber cloth instead of sweeping. Sweeping is more likely to stir up dust than to remove it.
Ban Shoes inside but offer slippers: More than half of household dust enters your home through windows, doors, vents and on the soles of your shoes. Think about where you walk all day long for example restrooms, city streets, construction, sites and etc. and all the bacteria and debris your shoes collect. Do you really want to track that inside? From the study of home where a doormat was added at the entrance and shoes were banned indoors showed that 60 percent reduction of lead dust and other contaminants in the home as well as significant reduction of allergens and bacteria. You first line of defense should be a coarse fiber heavy duty doormat placed outside exterior doors. Inside have everyone remove shoes at the door. Keep a bench a shoe rack and a basket of cheap slippers available so no one has to walk around in their stocking foot on chilly floors.
Clear the air while you clean the house: Your vacuum’s agitator brush and exhaust whip up dust that eventually settles on the surface your have just cleaned. Filter out some of that dust before it settles by switching your thermostat to fan on. This turns on the blower inside your furnace and filters the air even while the system is not heating or cooling. Leave the blower on for about 15 minutes after you are doen cleaning. But do not forget to switch it back to auto. Most blower are not designed to run constantly.
Reduce remodeling dust: Remodeling dust goes everywhere air flows so the key to stopping this dust is stopping airflow. Create an airtight plastic dust barrier curtain and completely seal the top and sides with tape. If you can not seal the bottom edge with tape then lay a board across it. Light plastic is fine for most job. If you need to pass through the dust barrier use heavier 4 or 6 mil plastic and add a adhesive backed zipper. Also make sure to seal both supply and return air ducts with tape and plastic. That way you will avoid plugging your furnace filter or coating every room in the house with a blanket of fine dust when the blower turns on. Please note that turn off the heating or cooling system while the dust are covered. Operating the system with restricted airflow can damage it.
