Assured Comfort

Do you ever feel like you dust a lot, and when you finish dusting you can already see more dust? Well, there may be a cause for this excessive dust.

Don't get me wrong, every home has dust, and 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. 

So what causes a home to be super dusty and what can you do to get ahead of it?

Well, below is a list of four common problems that lead to excess dust in a home, with explanations and solutions on how you can try to diminish the amount of dust that accumulates.

1. Air Filters

The first, and most likely, the cause of excess dust in your home is due to dirty or cheap HVAC Filters.

 If your air filter rarely needs to be changed because it is always clean, that simply means it is not working properly, and the dust particles are slipping through the filter.

When this happens, the dust slips through the filter and is then circulated throughout your home with the rest of the air being produced.


Your HVAC filter is the first line of defense against dust in your home, so invest a little extra money into a quality filter with a higher MERV rating.

A high MERV rating means that your filter will be able to catch microscopic particles of dust, like pet dander, lint, and old skin, which I am pretty sure nobody wants to float around their house. 

It is equally important to then change these filters on a regular basis. Leaving a clogged and dirty filter in your HVAC unit will not only cause more dust, but it can cause the unit to become damaged and prevent it from functioning at an optimal level. 

Ideally, you would change your air filter about every three months, and if your home is really dusty, you may need to change it more frequently.

The ultimate solution to dust relief an HVAC can offer is a whole house air cleaner. This professional grade duct system can catch up to 95% of pathogens and is often used in hospitals to keep the air clean and dust free. 

2. Leaky Ducts

If your filters aren't the problem, leaky ducts could be the cause of your excess dust. 

Leaky ducts not only over-work your HVAC Unit and raise your utility bills, but they could be letting out unfiltered, dusty air into your home causing dust to be spread throughout your house. 

Some major signs of leaky ducts include, 

  • Dirty and Lint Covered Vent Registers
  • Higher Energy Bills
  • Hot and Cold Spots in the Home


An easy way to determine once and for all if you have leaky ducts is to hire a professional 

HVAC technician to perform a pressure test on your system.

They will be able to tell you if your ducts need to be resealed. 

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.

This will save you money in the long run by evening out your home's temperature, reducing energy costs, and most of all, decreasing the amount of dust in your home.

3. Humidity Level 

Another main cause of dust is the humidity level in your home and outside your home.

Dry climates (inside and out) usually directly related to the amount of dust in your home. For example, you see a lot of dust in the desert and next to no dust in the rainforest.


If the air in your house is too dry, dust is more likely to be in the air.

Therefore, it is important to get a quality humidifier and find a good balance with the humidity level in your home. 

Also, dusty and dry air can be a sign of HVAC problems, so always have your unit checked if this becomes an abnormal issue. 

4. Flooring

Lastly, the type of flooring in your home may be responsible for the amount of dust that accumulates. 

There is no right type of floor, and both hardwood and carpeting have their pros and cons.

For example, research has shown that carpets harbor dust and dust mites, while hardwood flooring is not as likely to do that.

However, even though it is gross, it 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.


Regardless of your type of flooring, 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.

To prevent making your dust problem worse, invest in a HEPA rated filter for your vacuum. HEPA stands for high-efficiency particulate air,  this kind of filter is designed to catch particles .3 microns in size and larger at a 99.97% efficiency level.
