Air purifiers have far more benefits than simply allowing you to enjoy improved air quality in your home or workspace. They can also actively work to reduce triggers for allergy and asthma sufferers, and substantially improve their quality of life. Through the removal of pollen, dust, animal hair and spores, chemicals, and other potential triggers from the air, allergies can be vastly reduced, and the sufferer can live a more comfortable life.
So what are the critical differences between air purifiers? Here are the primary things to look for, and the guaranteed way to make the most significant difference in your quality of life and tackle allergies.
Why Use A Purifier?
By using an air purifier, you can remove harmful and potentially hazardous chemicals, gases, particles, and pollutants from the air. Though they may not seem to cause an issue, such particles can be triggers for those suffering from allergies, asthma, and other respiratory conditions. But which is the best air purifier for allergies?
Most air purifiers use particle filtration systems to catch and absorb particles before we can breathe them into our lungs. Two of the most common types of filters are HEPA and carbon or charcoal filters.
Activated charcoal filtration works by removing tiny microscopic particles using chemical absorption. The carbon then becomes activated when treated with oxygen which opens up millions of small pores in between the carbon atoms. This act increases the surface area in a small space, allowing for greater absorption of pollen and dust particles.
HEPA filters – High-Efficiency Particulate Air filters
These work to trap microscopic contaminants, and can eliminate 99.97% of all particles which are larger than 0.3 microns.
The fibers of the filter work to trap particles within the airflow. Any particles which are larger than one micron can stick to these fibers as the air passes; the efficiency of the HEPA filters means that even these tiny particles will be picked up.
Pros and Cons
Though both systems have benefits, they often neglect chemical pollutants and odors, which can be just as damaging and harmful as physical particles, particularly to those with allergies.
Some devices, such as those using carbon, will try to capture air pollutants through physical absorption alone, and often lack any destructive capabilities. This function means that any chemical elements will be released back into the environment to cause damage.
There is an option to combat this. Devices with a highly efficient ‘destructive absorbent’ for chemicals helps to eliminate both physical particles and chemicals. It works by having specially formulated materials containing metal oxides. When these come into contact with a chemical, the active sites of the metal oxide work to capture the chemical and initiate the neutralization process. A large surface area, unique shape, high chemical reactivity, and functional porosity all help with chemical absorption. As a bonus, odors are also neutralized.
This is the best option for allergies, as you can rest assured that the air is more thoroughly purified and is free from both physical particles such as dust and chemical pollutants as well.
