Purchasing an air purifier that has TRUE HEPA filters means that you are purchasing an air purifier that is going to really remove particles and allergens that cause allergic reactions and upper respiratory problems.

With a TRUE HEPA filter, it is guaranteed that the air purifier will remove at least 99.97% of all of the pollutants with a .3-micron size. The smaller the micron is, the smaller the particles that will be removed from the air.

This works attaching to the regular filter, so it removes the pollutants that pass through the TRUE HEPA filter.


A PECO air purifier is only found with a Molekule Air Purifier which means that it has a 2-part filtration system where the first one stops the particles and the second one removes the chemicals that are found in traffic and city pollution.

Things to Avoid
