When bushfire smoke invaded our homes and workplaces in 2020, air purifiers became a big-ticket item. Toxins in smoke, a primary asthma trigger, pose a serious threat to our health, and air purifiers, when properly selected and utilized, are one method to keep the air inside our homes safe.
An air purifiers filter impurities in the air, such as dust and smoke, and return clean air to the room. These technologies may aid people living with asthma in reducing indoor asthma triggers.
How Does Air Purifier Work?
The main purpose of an air cleaner is to remove allergens and particles that might aggravate allergy and asthma symptoms.
Using these machines, pollen, dust, mold spores, and other particles get removed from indoor air. Because some of these irritants are minute, having an air purifier can manage even the finest particles.
Because HEPA filters generally remove 98 percent of contaminants in the air, even those as fine as 0.3 microns, they are excellent for asthmatics.
Air purifiers work well for improving air quality and controlling allergies. One disadvantage is that portable air purifiers can only attract particles close to the device. If you have a serious allergy or asthma attack, you may need to install air purifiers in several rooms.
A whole-house filtration system is an alternative to a portable air cleaner. It improves air quality throughout your home, removes up to 99.98 percent of airborne allergens, and traps particles down to 0.1 millimeters in size.
Remember that air purifiers aren’t the only way to protect yourself from unpleasant particles. Other steps to reduce allergies in your house include vacuuming daily, closing windows, washing clothes, and bedding in hot water.
Know Your Options
There are many air purifiers available on the market, and devices can range in price from low to high. While some filters can remove bad smells and other contaminants from the air, three types of air purifiers are recommended for alleviating asthma and COPD symptoms. It will help if you discuss the matter with your doctor to determine which of these three options is best for you.
1. HEPA Air Purifiers
Pleated filters in HEPA purifiers catch small air particles. The air is forced through the filter with the help of a fan, trapping allergens and contaminants and then releasing cleaner air. For big particles like pollen, pet dander, dust, smog, and smoke, HEPA filters are extremely effective. However, they do not kill germs or mold spores; they merely trap them.
2. Electronic Air Filters
Electrical charges attract and dump allergens and irritants in electronic air filters. Particles are captured within the system if the device has collecting plates; otherwise, they attach to room surfaces and must be wiped away. The fact that practically all of these units produce minor ozone levels is a disadvantage.
They emit electrically charged ions that attach to air particles in the room. So they stick to your curtains or shades, walls, or ceiling tiles instead of floating around the room.
Mechanical and electrostatic filters are combined in hybrid air filters.
4. Gas-Phase Air Filters
Activated carbon granules are used in gas phase air filters to remove odors (volatile organic compounds, or VOCs) and non-particulate pollution such as cooking gas, paint fumes, and construction materials.
Tips to Reduce Allergens
Other strategies for reducing allergies in the home include:
- Installing an air conditioner. It is beneficial to save mildew from forming in regions like the bathroom.
- Wear a mask if the residence turns polluted.
- Use dustproof covers to your bed and pillows.
- Changing your bedding regularly.
- Weekly vacuuming. Keep dust from returning to the air by using a high-quality vacuum.
- Dumping off things that can trap dust and other allergens. It includes surface clutter. Your carpets additionally entice many allergens, so attempt to use hardwood flooring when you have bronchial allergies.
- Close your home windows in the course of the pollen season. Take care specifically in case you don’t have air conditioning.
- Maintaining the cleanliness of pets by grooming or bathing them regularly. It can help reduce pet dander.
Try keeping a symptom log next to your peak flow log and note when you started using the device to find out if the air filter is working for you. You can then see if this has helped improve your asthma symptoms; that doesn’t necessarily mean you can reduce or stop your asthma medications and consult with a lung specialist.

It would help if you understood that while you notice asthma triggers around your home, consider the link between air pollution and asthma. Fortunately, a healthy environment for people with asthma is easy to maintain by using an air purifier.
2. What are the health risks associated with air purifiers?

3. Are air purifiers effective in Covid?
Air cleaners and HVAC filters can help reduce airborne contaminants, including viruses, in a building or small space when used properly. Air cleaning or filtration is not enough to protect people from COVID-19.
