The purifier removed 98% of particles smaller than 0.3 microns, 72% of particles smaller than 2.5 microns, and 73% of particles smaller than 10 microns at level 6. We discovered that at level 10, the purifier captured 95% of particles smaller than 0.3 microns, 96% smaller than 2.5 microns, and nearly 100% smaller particles smaller than 10 microns.

Based on these limited tests, our findings do not support Dyson’s claim that it can remove 99.95% of particles.

Do air purifiers work?

Air purifiers have also been found to help reduce the presence of particles in the air that cause allergic reactions, which can cause asthma attacks, depending on the type of allergy and the trigger. During times of high humidity, dehumidifiers can also help people with asthma. Air purifiers can be useful in situations where your indoor space has little or no ventilation, especially if you want to combat smoke and its odor.

It is unknown whether air purifiers help to prevent the spread of COVID-19 indoors. If the weather permits, the Centers for Disease Control and Prevention (CDC) recommends opening doors and windows to allow a good flow of air inside. HEPA filters, found in some air purifiers, have been found to remove some viruses from the air.

What are HEPA filters?

You’ll notice that most of the air purifiers for rooms we tested have a high-efficiency particulate absorbing (HEPA) filter. These can remove 99.97 percent of air pollutants as small as 0.3 microns, effectively eliminating most indoor air pollutants.

To put things in perspective, most dust particles are about five microns in size, and pollen is a whopping 10-1,00 microns – all of which a HEPA filter can trap and remove.

Air purifiers work by sucking dirty air from home into filters via a fan. These then filter out any impurities before returning the clean air to the room. It’s important to note that eliminating all particles that can live on walls, carpets, bedding, and hard surfaces is impossible.

Air purifier benefits

For people with respiratory issues, such as bronchial allergies or allergies, clean air can mean the difference between a living wave goodbye and an international pandemic. We should be extra concerned about the air quality and whether it contains airborne viruses that could make us sick.

More research is needed to determine if at-home air purifiers make a significant distinction for people with bronchial allergies. However, it makes the experience that the purer the air, the easier it’s for everybody with respiration issues and allergies. If you have bronchial allergies and need to buy an at-home air purifier, keeping a diary is a good idea to see if it makes a difference in your symptoms. However, keep in mind that an air purifier will no longer remove all impurities, so bronchial allergies must be managed as prescribed by your doctor.

The same is true for people who suffer from allergies; the air purifier can control pollen, and dirt will assist and will, of course, depend on the time of year when pollen counts are higher.
