Do you ever feel like this when you finish dusting and you can already see more dust? Dust in homes, offices, and other human environments contains small amounts of plant pollen, human and animal hairs, textile fibers, paper fibers, minerals from outdoor soil, human skin cells, burnt meteorite particles, and many other materials which may be found in the local environment. Don’t just assume your home is dirty, as this dust may not be the product of idle accumulation. Instead, it could be a sign your heating, ventilation, and air conditioning (HVAC) system is not trapping dust properly. Only dusting won’t fix this issue. The dusts on your furniture is just a fraction of that total amount. The rest of the dust is in the air, in the ducts, in the HVAC system, and outside waiting to come in.

There isn’t really anything you can do to prevent the production of it, but you can manage your dust and learn ways to more effectively remove it before it settles all over your furniture.

Air Filters

This is the most common reason when you think of Why is my house so dusty? If you live in a hot, arid climate, you’re probably getting a fair bit of dust coming in from the outside. Your filters combat the dust and impurities and they gets caught and stays put. But if the filters are filthy, air won’t pass through, and dust will simply bounce off and settle somewhere else in the house. Because your old fitted cheap HVAC filters are so dirty and ill-serviced or not serviced that it is having all the variants of dust stored inside in a corner of it which helps in mixing these dust particles with the fresh air coming into your house. It is surely a common thinking of all of us that the HVAC system of our house is very clean and we may service or change it when it stop working.

Possible Solution: Ideally, you need to be changing your filters every 2-4 months but if your home is really dusty, you may need to change it more frequently. Change your filters regularly, stay on top of routine maintenance, and make sure you’re not skimping on filters. Invest in quality filters; you can get a recommendation on brands from a trusted HVAC contractor. Buy air filters with a higher MERV rating. The higher the MERV rating, the smaller particles it can catch. Typical fiberglass filters are rated 1-4. You want filters that are at least 5-8. The best possible solution is to have a whole-house air cleaner in your HVAC system. This professional grade duct system can catch up to 95% of pathogens and is often used in most of the hospitals to keep the air clean, germ free and dust free. Once you do clean or replace your filter, establish a monthly schedule for this task. We recommend either the first or last day of the month.

What kind of flooring in your home may also be responsible for the amount of dust that accumulates in your environment. Both the hardwood and carpeting have their own positives and negatives. Carpets are harbors’ of dust and, therefore, dust mites. Most homeowners thinking vacuum cleaning gets rid of this problem, but it is not as simple. Research has shown that carpets harbor dust and dust mites, while hardwood flooring is not as likely to do that. According to another study by the Queensland University of Technology, “Both vacuum cleaning and the act of vacuuming can release and re-suspend dust and allergens, leading to increased exposure.” Carpet flooring can actually be beneficial when the carpet holds in the dust because it allows you to vacuum it up easier. Hardwood, on the other hand, tends to let dust blow around and back into the air when sweeping, vacuuming, walking, or any other activity that may stir up the air and consequently the dust.

Possible Solution: It really doesn’t matter much what type of flooring you are having in your house, but you should invest in a quality vacuum cleaner that will effectively sweep up the dust and dirt and prevent it from being released back into the air. Also to prevent making your dust problem worse, invest in a good HEPA rated Air Purifier for your house. “HEPA” stands for “high-efficiency particulate air.” To be rated as such it need to catch all particles .3 microns (very tiny) in size or larger at an efficiency level of 99.97%.

When your ducts leak that make your system work harder and less effective and also they could be letting out unfiltered, dusty air into your home causing dust to be spread throughout your house. According to a study, the typical home loses about 20-30% of the air flowing through the forced-air system’s ductwork, mostly through holes or gaps around fittings or from unsealed joints between duct sections. It’s like running water through a hose with a bunch of holes in it — it’s not going to work very well. Some of the common symptoms of leaking ducts is that some parts of area will be noticeably hotter and some will be colder because all the conditioned air isn’t making it there. Also you will feel that the energy bills have gone up.

Possible Solution: Have a professional HVAC technician perform a pressure test on your system to see if your ducts need sealing. If it is determined that your ducts are the issue, it would be in your best interest to have your ducts cleaned and resealed by a professional. If you do have leaky ducts, have them sealed them ASAP.
