Last Updated: February 27, 2024
Do you feel that no matter how well you vacuum or dust your home, there’s still dust in the air? According to the Environmental Protection Agency, there is growing evidence that the air inside our homes can be more polluted than outside. Considering that people spend most of their daily lives indoors, It means exposure to polluted air most of the time.
Dust exposure can have varying effects on your health and adversely impacts people with allergies or asthma. Dust allergy can cause sneezing, runny nose, wheezing, itchiness, and watery eyes when inhaled. It is the leading cause of all-year-round allergic rhinitis and a typical indoor allergy. Dust isn’t always visible and, therefore, is challenging to handle. Dust comprises accumulated tiny particles such as soil tracked into the home, particulate matters from outside air, dead skin cells, hair, pet hair, cloth fibers, dust mites, food particles, pet dander, etc. The type of dust indoors also varies based on location, outdoor environment, number of people living in the house, etc.
There are several preventive measures and treatments to tackle dust allergy. An air purifier is a proven and safe method to alleviate dust allergies and help you breathe better by significantly reducing the pollutants in your home.
How Can Air Purifiers Help Reduce Dust?
An air purifier circulates clean air by capturing the dust before it settles on the couch, shelves, bed, wall, and floor with the help of fans and filters. It draws dust and other particulate matter through the internal fan into the filtration system. The filters capture the pass-through contaminants and release purified air back to the room. The cleaning cycle continues until you turn off the air purifier.
A dust air purifier can be beneficial to people that are hyper allergic to dust and experiencing chronic sneezing or stuffy nose and is ideal for people living in a dusty environment.
Things to Consider While Selecting a Dust Air Purifier
Dust and dust mites are microscopic and consist of a variety of debris, contaminants, and allergens. It is ideal to have at least 3-stage filtration for effective dust removal, including a pre-filter, a HEPA filter, and a carbon filter. While there are several options available in the market to work as a dust air purifier efficiently, it should contain:
Pre-filter – Pre-filter traps particulate matter about 2.5 to 100 µm in diameters, such as dust, hair, and debris. It also protects the HEPA filter by reducing the number of particles coming through.
True HEPA Filter – This is the highest level of filtration. In order to carry this label, all HEPA filters must conform to the standards set by the Department of Energy (DOE) and capture at least 99.97% of particles as tiny as 0.3 microns. True HEPA filters are not washable and should be replaced after six months to one year. We have prepared a list of air purifiers with HEPA filter.
HEPA-type filter – A HEPA-type air purifier is a lower-grade version of a True HEPA filter. There is no quality standard for these types of products, and most of the time, no clarity on their effectiveness.
Activated carbon filter – It is a non-washable, deodorizing filter that focuses solely on capturing gases and odor via chemical absorption. It helps in removing odors and making your home smell fresh. In its raw form, carbon is not effective in absorbing odors and needs to be activated first. This is done by a process in manufacturing where they heat it until it hardens and cracks. With the new cracks and crevices, carbon can absorb a wide variety of odors,
Ionizer – The ionic filter or a negative ion generator acts as a secondary defense against dust, allergens, and other germs. It disperses negatively charged ions into the air, which latch onto positive airborne pollutants. These combined ions will become heavier and drop, which will then be collected by the air purifier. As new particles enter a room, the True HEPA filter will need some time to cycle the air and draw them into the filter. Note that an ionizer must comply with the regulation set forth by the California Air Resources Board (CARB) on the ozone emission concentration limit.
ACH – The Air Changes per Hour (ACH) determines how often the air purifier can replace the air within a room with clean, fresh air every hour. This number is usually depicted with an x and a number following it. E.g., an air purifier with an ACH of x3 means that every 20 minutes, the air in the room filters out.
It is ideal to consider an air purifier with a higher ACH to purify the air in a large room. Please note that the air purifier’s ACH measurements are taken while running on the highest fan setting. If you don’t plan on running your purifier on high, choose an air purifier with an ACH that accommodates a larger room than where you plan to use it to effectively remove dust and dust mites, pollen, and other particles that cause allergies. Check out the best air purifiers for large rooms.
CADR – The Clean Air Delivery Rate (CADR) determines the air purifier’s effectiveness in cleaning the air within a particular size room and producing clean air by volume. CADR is measured in cubic feet per minute (CFM). The higher the number, the quicker it can remove dust in the air for each particle size range. Most devices are given three CADR ratings for smoke, pollen, and dust.
AHAM Certified – Check if the air purifier is certified by the Association of Home Appliance Manufacturers (AHAM). The EPA recognizes AHAM to test and verify products for the Energy Star program to ensure safety and efficiency and provide CADR rating and size guidelines. An AHAM-tested air purifier is that it gathers all the information you need in an easy-to-understand number. The downside to AHAM tests is they are conducted in a manufactured environment which may not resemble the real-life conditions. To compensate for this limitation, choose an air purifier that is slightly more powerful than your requirement to accommodate the additional conditions in a real life house.
Noise Level – True HEPA filters and activated carbon filters add a lot of airflow resistance; hence it is challenging to keep the noise level low. Noise is measured in decibels and is represented on a logarithmic scale. This means that for every 10 dB increase, the sound level doubles. So a 60 dB noise level air purifier would be twice as loud as a 50 dB machine. If you plan to use the air purifier during sleep, consider the dB level at the lowest and highest setting
How to Reduce Dust in House
Dusty home can create an unhealthy environment for the occupants. While an air cleaner can make a huge difference, you will still need to do house chores to reduce the overall exposure. Below are some pointers you can follow to avoid dust accumulation in the house.
Clean air filter- Filters in ventilation, HVAC, air conditioner, and air cleaner require cleaning regularly. Check the manual on the filter’s periodic maintenance.
Vacuum regularly- Vacuum thoroughly and cover all corners of the house, including hard-to-reach places and carpet. To avoid stirring up dust in the air, consider a vacuum with a HEPA filter that traps the particles.
Change bed linen regularly- Clean your sheets, pillows, pillowcases, and comforters at least once every week in hot water to kill off dust mites and remove loose fiber. You can switch to hypoallergenic covers for better dust mites protection.
Avoid carpet and faux- While carpeting and rugs may look nice and feel great under your feet, the truth is that these materials are a magnet for dust and harboring dust mites. Do a deep cleaning of carpets and rugs with a vacuum regularly to stop the dust mites from multiplying, which can cause unpleasant allergic reactions. It is ideal to remove any carpeting and rugs that you can and replace them with solid flooring (e.g., hardwood, tile, laminate, or vinyl).
Avoid feather dusters- A feather duster moves dust from one place to another. You can use a damp cloth to wipe down surfaces to collect dust particles more efficiently than a feather duster.
Dust properly- Use a damp cloth or sponge to clean surfaces and trap dust. Start at the top and work your way down to avoid scattering too many dust particles in the air.
Change your HVAC air filter- The filters in the heating and air conditioning system get dirty quickly. Make sure to change this filter once per month so trapped dust doesn’t float back through the system and into the various rooms in the house.
Keep dirt out- Place high-quality doormats in front of every door and make everyone take off their shoes as they come in. Having a shoe tray to the door is also a good idea. This step will reduce the amount of dust and dirt that comes inside from the outdoors.
Clean Rugs Outside- Clean your rugs outside the house by beating them against a hard surface or draping it over a ledge and hitting it with a broom or other wide solid object to get the dust particles and dirt out.
Vacuum under Furniture– Clean underneath your couch and bed regularly, at least every two weeks, as they are often overlooked. Dust can easily travel to other areas of your home whenever there’s a draft in the room, or the air conditioner runs.
Open the windows- Ventilating your home with fresh air is the fastest way to filter out dust from your home.
Select Manufacturer Recommended air filters- Avoid cheap and flimsy air filters as they cannot provide complete protection and tend to break down quickly. Always go for manufacturer-recommended filters. Don’t forget to change filters regularly to eliminate dust effectively.
