The Best Air Purifiers for Airborne Dust

To choose the best air purifiers for dust it helps to understand that dust is not just dirt. It is miniscule particles, which can come from various sources. Studies on household dust have found that it can contain everything from particles from lead paint, pet hair, cotton fiber, dead skin cells, pesticides, to pollen, and other allergens. Dust can build up rapidly and be a nuisance to clean up, especially during the dry summer months. Dust also contains dust mites and their feces. Breathing these polluted particles into the lungs can be very dangerous because their microscopic size allows dust to penetrate into the inner lung. This exposure can cause difficulty breathing, and worsen existing lung conditions. To effectively reduce the amount of dust in the home, it is recommended to invest in an air purifier for dust elimination.

HEPA Filters

There are different types of air purifiers useful for various potential health problems. Most experts agree, however, that the best air purifier for dust is one that uses a high-efficiency particle air filter. HEPA refers to a filter type that uses a mesh to capture particles as the air flows over the filter. These filters are designed to capture suspended particles measuring 0.3 microns in diameter or greater. Not all HEPA filters are made to the same quality standards, however. When shopping for an air purifier, check to see the percent of particles that are captured by the air purifier. Dust removal filters can range from removing 85 percent of particles to over 99 percent. A true HEPA standard filter, however, is one that can remove a minimum of 99.97 percent of particles.


The amount of filtration is an important concern when deciding on an air purifier. For dust removal in homes where occupants have mild to moderate allergies, it may be more economical to purchase a filter that is not a true HEPA filter but is similar. These similar filters are usually less expensive and still remove a significant portion of dust from the air. Regular dust-busting such as weekly washing of bedding, dusting furniture, using a HEPA vacuum, and mopping can further help reduce allergies when used with an air purifier for dust elimination. If asthma or severe allergies are occurring; however, a true HEPA filter will more effectively cut back on breathing in dust. As there is less dust in the home, the likelihood of suffering from asthma attacks or acute allergic reactions requiring medical attention can decrease. Therefore, even with the cost of buying replacement filters, the best air purifiers for dust more than pay for its price over time.

Air filters are not always defined by HEPA standards; they are often described by their minimum efficiency reporting value MERV. This measurement describes how effective the air filter is at removing particles of different sizes from 0.3 to 10 microns in the air purifier. Dust removal classifications start from one and go up. The higher numbers reflect the best air purifier. For dust control, these purifiers are able to remove smaller microns and a greater amount of contaminants. These filters are often preferable to HEPA filters in heating, ventilation, and air conditioning HVAC systems because they can also remove ultra fine dust particles without the air resistance and changes in pressure caused by HEPA filters.

Size Concerns

Part of choosing the best air purifier for dust is deciding between the various sizes. There are portable units and whole house purifiers for improving indoor air quality. A room air purifier is a lightweight, compact unit that is easy to move, but they are only designed for one room in the home. This design may be well suited for placing in a room that accumulates more foot traffic which leads to more dust. For instance, families usually spend hours in their living rooms and bedrooms watching TV, interacting, and playing with pets. Typically, these rooms will have much more dust than a room which is rarely used but kept clean. The square footage of the room should also be considered to prevent overpowering the air purifier. Dust removal systems on the market are usually labeled with the optimum room size that the purifier should be used with. For instance, a purifier designed to use with a room of no more than 200 square feet will be ineffective in a bedroom or office measuring twice as much.

Whole-house best air purifier for dust removal systems have the benefit of not being a visible blemish as they are housed inside of a building’s HVAC system. While the system is running, air particles get trapped, and air gets cleaned. These systems can offer adequate dust reduction for those who want to worry about maintenance less often and those in homes where most of the rooms are regularly used. They can also be a more efficient option in large homes with several stories above ground level. The availability of replacement filters and ease of ordering are also important considerations when looking for the best air purifiers for dust eradication.
