best air purifier for asthma

If you suffer from asthma, you know that it can be a real pain having to constantly take your asthma pills or use your inhaler. However, the best air purifier for asthma will help to keep your asthma under control and reduce your intake of medication.

According to statistics, millions of people around the world suffer from asthma. And the fact that the quality of the air we breathe inside our homes is more poor than outside is making matters worse. While it’s not known what exactly causes asthma, nor the actual cure for it, there are some reasons why it’s getting worse for you at home. One of the major culprits is a decline in the quality of your indoor air.

This may be caused by the way your home is designed. Very little air conditioning and heating create a tight seal throughout your home. Another issue is not opening your windows for ventilation, thinking that you’re protecting yourself from outside allergens. Meanwhile, the real problems are the harmful pollutants in your home that don’t have anywhere to escape to. So they build up inside your home and trigger your asthma.

Fortunately, you can use one of the following options of the best air purifier for asthma to find relief for your condition.

What Is Asthma And What Are Its Symptoms?

Asthma is a chronic disease that affects the respiratory system of children and adults, and it can be genetically passed on or developed as you grow. It’s an incurable illness that affects your airways, causing inflammation and tightening of muscles, restricting air supply. As asthma develops, your airways become swollen and sensitive to substances you might inhale like pollen, dust, chemical fumes, cold and dry air, or tobacco smoke.

Some common asthma symptoms include:

  • Tightness in the chest
  • Wheezing
  • Coughing
  • Shortness of breath

Features To Consider In The Best Air Purifier For Asthma

The best air purifier for asthma is one that can remove all particles in the air that might trigger flare-ups. With clean and fresh air indoors, it will help improve your health and help you breathe easier and reduce your asthma attacks. However, there are some features to look for in an air purifier to avoid buying the wrong type that might even make your asthma worse.

HEPA filter

Air purifiers with HEPA filters are very common in most homes and offices. This is a highly dense paper filter that collects most of the large and smallest particles that irritate your asthma, with a 99.9% efficiency. Once the particles are trapped inside the filter, they can’t float back into the room which leaves the room with clean, fresh air. The true HEPA filter is the best if you’re suffering from asthma. It’s the only filter that can remove most of the particles in the air. Standard HEPA filters only capture larger particles and not the tiny ones. So if you have asthma, look for an air purifier with a true HEPA filter to help reduce the majority of your asthma-inducing triggers.

Activated carbon filter

Carbon filters use activated charcoal to absorb airborne odors, smells, and gases from your indoor air. As an asthma sufferer, carbon filters help you by chemically removing all the impurities instead of just filtering the particles in the air. Although carbon filtration is designed to remove VOCs from the air you’re breathing, it can also benefit people with asthma by absorbing some of the chemical irritants in the air. Together with the HEPA filter, this traps all the particles. This will help to minimize your exposure to chemicals, odors, and VOCs that will irritate your lungs.

PECO

PECO stands for Photo Electrochemical Oxidation, a new technology that is used to destroy pollutants instead of just filtering them from the air. By incorporating the physical filter and the photochemical reaction, there is oxidation of the organic matter in the process. This helps to destroy allergens like pollen, pet dander, mold, and VOCs that trigger your asthma symptoms.

Air Purifiers To Avoid

Ionizers

An ionizer air purifier emits negative ions into the air which attract positively charged particles in the air. This weighs the particles down and the pollutants then fall from the air. However, ionizers affect asthma sufferers because they’re not very effective in getting rid of dust, spores, and smoke. They also  generate ozone, which is an asthma irritant that can trigger your symptoms. Even the smallest amount of ozone can cause complications and lead to the development of chronic lung disease.

Ozone generators

Some air purifiers claim to use ozone to improve indoor air quality and create a safe byproduct. This can be harmful to your health and even cause chronic respiratory issues, including asthma. Exposure to ozone can irritate your lungs and trigger a severe asthmatic attack. Although low levels of ozone in an air purifier may not cause a serious reaction, it’s better to be safe than sorry.
