Can Air Purifiers Reduce Indoor Dust? Here’s What You Need to Know

No matter how meticulous you are about cleanliness, every home still has a certain amount of dust. And you can’t help but breathe it in. The problem arises when you’re sensitive to dust or other allergens that can trigger allergic reactions like runny nose, sneezing, watery eyes or coughing. This is where a dust air purifier comes in handy. 

Air purifiers claim to reduce dust and other contaminants, but how effective are they? Can air purifiers help remove dust and improve our indoor air quality? Don’t worry, in this article, we will cover everything you need to know about using air purifiers to reduce dust in your home. 

How Do Air Purifiers Work?

As dust particles circulate in your indoor air, an air purifier draws the surrounding air through its filters to trap these unwanted particles. When the air floats on the other side of the purifier, the result is much cleaner air carrying minimal contaminants. Although an air purifier can’t fully purify the air, it can significantly clean it to make it healthier for you to breathe. 

Keeping this in mind, the success of an air purifier depends on its filter or filters. Most air purifiers use a high-efficiency particulate air (HEPA) filter, which can capture particulate matter (PM) 2.5 and particles as small as 0.3 microns. These particles are even smaller than human hair and invisible to the naked eye but can still penetrate your lungs, with PM 2.5 being the most dangerous of them all. 

Our MedicAir Pro Mini goes beyond this and leverages the combination technology of HEPA 14 activated carbon filter and safe UV tech, which removes PM 2.5 and microscopic particles such as dust, animal dander, pollen, mould spores, smoke, and VOCs down to 0.1 microns. The result is 99.99% cleaner air. 

Things to Keep in Mind While Using an Air Purifier for Dust

Here are some things to remember while choosing a dust air purifier:

1. Clean Air Delivery Rate (CADR)

CADR measures how much clean air an air purifier can deliver in a given time. The higher the number, the faster the unit can filter the air for particles such as dust, pet dander, pollen and smoke. Our MedicAir Pro Mini offers a CADR of 410 metric cubes per hour, which is sufficient for an average-sized room. Additionally, its highly efficient fan can easily achieve 10 air changes an hour or above, faster than most air purifiers in the segment.

2. Size of the Room

The size of your room also affects the CADR you require. As a rule of thumb, the CADR of your air purifier should be equal to at least two-thirds of your room’s area. For instance, a 200-square-foot room needs a CADR of at least 130. Larger rooms or rooms with higher ceilings may need more. 

To get a correct estimate, you can use the product finder on our website that helps you determine which air purifier is right for your needs. Additionally, it can calculate how many units you’ll need based on the dimensions of your room.

3. Placement of the Air Purifier

It is also essential to place the air purifier correctly to ensure optimal performance. Ideally, you should install the air purifier where you spend most of your time indoors. Alternatively, you can place it near the source of dust or in an area with good air circulation. Additionally, remember to take off the filter cover before using the purifier and make sure nothing blocks the airflow around your unit.

4. Type of Filter(s)

Air purifiers employ multiple filters to trap and remove dust particles from your air. While a HEPA filter is a must, you should also look for air purifiers with HEPA 13/14 filter and carbon-activated anti-bacterial layer. Anti-bacterial layer helps prolong the life of your HEPA filter while activated carbon filters remove odours, gases, smoke and VOCs from the air.

Our MedicAir Pro Mini leverages an anti-microbial pre-filter, HEPA 14 activated carbon filter and safe UV technology to capture, remove and neutralise microscopic particles, harmful chemicals and pathogens from the air.

5. Maintenance

Lastly, it’s important to replace the filter every 3-6 months or as directed by the manufacturer to ensure optimal performance of your air purifier. Our MedicAir filters are built to last 6-12 months, and with our subscription service, you’ll automatically receive a new filter every 9 months at a discounted price. Over time, filters can become clogged, reducing their effectiveness in capturing dust particles and other contaminants. So, regular maintenance and filter replacement is crucial to keep your indoor air as clean as possible. 

The Bottomline

In conclusion, air purifiers are a worthwhile investment to remove dust from the air you breathe. Besides removing dust particles, air purifiers can also help reduce other pollutants such as pet dander, pollen, smoke, odours and pathogens from your home, thereby improving your indoor air quality. When shopping for an air purifier for dust, remember to check its CADR, types of filters and your room size. Proper placement and maintenance of the air purifier will ensure optimal performance and longevity of your unit.
