Why Is My House So Dusty?


By Carrie Dixon, Blog Editor

Dust in a houseDo you find yourself dusting your house over and over, only to see more dust the next day? If you think the dust in your house is excessive, you’re probably right! It’s not normal to see dust reappearing just a day or two after you dusted. Unless you live on a gravel road where dust is constantly entering your home from the outdoors, you should be able to keep your home dust-free with a regular cleaning schedule. There are several reasons why a home may be extremely dusty, and luckily they are all things that can be addressed. Here are some common things to consider when trying to combat the dust in your home:

Is Your HVAC Filter Clean?

The first thing to consider when your home starts to get very dusty is how long ago you replaced your HVAC filter. This filter shouldn’t need to be cleaned very often, maybe twice per year, but if you can’t remember when the last time was, you likely need to give it a look. This filter stops dust particles from being blown into the air through your air conditioning or heating vents, and prevents other allergens from being blown into the air as well. If the filter is very dirty, then it can’t stop the particles from slipping through.

Another problem with HVAC filters could be the quality. If you are noticing a lot of dust even with a clean filter, consider buying a filter of better quality. It could be that a cheap HVAC filter isn’t doing as good a job as another filter might. There are filters designed specifically for capturing more allergens in homes where air quality is poor. Grab a filter with a higher MERV rating and see if it improves the dust.

Are Your HVAC Ducts Leaking?

Another problem that can lead to dusty homes is leaky HVAC ducts. If you see a lot of lint and dust covering your vent grilles, if your home has a lot of hot and cold spots where it seems that the heat or air conditioning works better, or if you’ve noticed that the energy bills are suddenly much higher, you likely have leaky ducts. All this means is that your HVAC ducts need to be resealed, which can do a lot for keeping your home dust-free.

Hiring a professional HVAC repair service will be your best bet for fixing this issue. In addition to resealing the leaky ducts, they will also clean out the ducts so that the dust being blown into your home is gone. You’ll also save money on your energy bills, and even out the temperature in your home.

Is Your Home Too Dry?

One problem that can lead to a lot of dust in the home is a low-humidity environment. If the humidity in your home is less than 40%, you likely have a home that is too dry. This can cause more dust for a variety of reasons. Dry air causes more shedding from fabric, more shedding from animals, and more shedding from you! Your own skin will become drier and dandruff is a part of the dust that you see.

You can combat this issue by adding a humidifier to your home, or trying to balance the humidity in other ways. The most ideal range of humidity for a home is between 40 and 60%. If you run your air conditioner or heater a lot, this can cause the air to dry out as well, so consider cutting down on your use of these units and using fans or other methods to cool or heat your home.

Do You Have Carpet or Hardwood?

Your flooring can actually cause more dust to accumulate in the air and on your furniture, but you may be surprised to learn that it’s hardwood that’s the problem, not carpet. Although it doesn’t sound very attractive, carpet is better for dusty homes because it captures dust and clings on to it – making it easier for you to vacuum up. Hardwood, on the other hand, allows dust to be swept back into the air any time someone walks on it or sweeps it up.

A good vacuum cleaner, or a microfiber sweeper that grabs dust, will be essential for cleaning your floor in a dusty home. It’s very important that you grab dust off the floor as soon as you see it. If you are considering a remodel, and want to combat dust in the air, go for carpeting where you can.

If you want to keep your home dust-free, there are many other things that you can try, including investing in different window treatments, trying out different air filters, and more. But just remember that you don’t have to live with all that dust! There are ways to address this issue to make your chores less of a headache.
