Does Air Purifier Reduce Dust From The Home?

You’re using an air purifier to clean the air and return it to you, but one question must have struck you, does air purifier reduce dust?

The truth is that an air purifier is the most critical device for ensuring that the air quality in your home is nearly dust-free. You can breathe cleaner air and live a much healthier and more relaxed life if there is no dust in the air. 


So, does air purifier reduce dust? In this article, we’re going to show you if an air purifier truly reduces dust and we’re going to talk all about it.

What is dust made of and why you should care about it

Before we go on to answer your question, “does air purifier reduce dust”, we must first learn what dust is. If you reckon that dust is either dirt or dead skin cells, you are probably wrong.

According to Layton & Beamer, 2009, the dust you’ll find in your home is a complex mixture that includes primarily:

  • Soil that has been brought into the house 
  • Particulate matter from the atmosphere 
  • Organic stuff
  • Organic material comes from plants and animals (officially, scientists describe “organic” as carbon-based compounds). 
  • This organic material contains the following:
  • Particles of skin 
  • Food debris
  • Mold
  • Pollen
  • Pet dander 
  • Body pieces of insects 
  • Allergens from dust mites

Pamela Beamer, the study author, told NPR that the indoor components of dust may include items you may not think of right away, such as fibers from your carpet or bedding.

Dust can irritate your eyes, nose, and throat, making it difficult to breathe, especially if you have allergies, asthma, or other respiratory conditions. If dust causes your asthma or allergies to worsen, you most likely have a dust allergy.

What concerns everyone is those small dust particles frequently float in the air, and if they are small enough, they can enter the lungs and cause health problems.

Does air purifier reduce dust?

The simple answer to the question “does air purifier reduce dust” is yes; most air purifiers on the market are built to filter out large dust particles. Mechanical filtration, which is a method of capturing pollutants on filters, is used in many of them. The particles are either supposed to stick to the filter or get caught in the filter fibers. You’ve probably heard of a HEPA filter, which is a mechanical filter that traps particles in the air.

Mechanical filters are either pleated or flat, similar to HEPA filters. A flat filter is a simple furnace filter or a filter in your HVAC system that can trap a small amount of dust in the air, though they are too basic to be used in an air purifier (this is your basic throw away or washable filter). For increased particle “stickiness,” a flat filter could be electrostatically charged.

How does Air Purifier reduce the dust?

Now that we’ve answered the question “does air purifier reduce dust”, the next question that arises is “how”. 

 the true HEPA filter is the most important tool for dust removal. HEPA filters were developed in the 1940s to protect scientists working on the Manhattan Project from microscopic radioactive particles, and their effectiveness at removing particles from the air led to their commercial use in filters and vacuums. 

A true HEPA filter can capture particles as small as 0.3 microns with 99.97 percent efficiency, but it can also capture much larger and smaller particles. The 0.3-micron size was chosen because it is the most difficult to trap while also being the easiest to draw into the lungs.

An air purifier circulates the air in a room, capturing all of the tiny particulate matter floating in it, including dust, as it does so. The air easily passes through the filter, but the particles get caught in the fibers. 

These particles become trapped because they would otherwise turn into dust on household surfaces or cause allergy or asthma symptoms if inhaled. Although an air purifier cannot completely remove particles, it can significantly reduce household dust with regular use.


The second type of air purifier that is designed to remove dust particles is electronic air cleaners. These may be either electrostatic or ionizing air purifiers.

Is it a good idea to invest in an Air Purifier?

Before you go on to make the purchase, keep in mind that air purifiers aren’t a panacea. There is very little scientific evidence that air purifiers help improve your health or relieve allergies and respiratory symptoms. This is partly due to the difficulty of distinguishing the effects of known air-quality pollutants in your home from the effects of other environmental and genetic factors.

However, if you suffer from allergies or asthma, an air purifier with a HEPA filter may be beneficial to you because it is effective at removing fine airborne particles.

What features do I look for in a dust-reduction air purifier?

CADR (clean-air distribution rate) rating 

This is a measurement of the purifier’s cleaning speed for removing smoke, dust, and pollen. Look for a CADR of at least 300, and anything over 350 is fantastic. 

Size recommendations

A model that is configured to function in the room size is needed for proper efficacy. If you want to run it at a lower, quieter setting, choose a model that is built for a larger area than the one you are outfitting it for.

AHAM (Association of Home Appliance Manufacturers) Verified mark

The AHAM standards are intended to ensure the safety, reliability, and performance of a wide range of home health care equipment, including air purifiers. The standards are intended to facilitate the buying process by establishing a shared agreement between producers and consumers.

Although this certification program is optional, most reputable air purifiers have gone through it, and also include CADR ranking and size guidelines.

True HEPA

True HEPA filters are capable of filtering out ultrafine particles (think: dust, dander, pollen, mold, and other common allergens in the home). It’s important to remember that the actual effectiveness of these devices in real-world environments will be much lower, as new contaminants emerge regularly.

Conclusion

You must now know the answer to the question, “Does air purifier reduce dust?” It is important to note that dust cannot be completely removed. Using a dust air purifier in each room, on the other hand, is a great way to help minimize dust in the air. We only wish you good health and cleaner air.
