At New Jersey Tai Chi, we love the outdoors and train in the park whenever possible. When the weather isn't ideal, we train indoors at our facility, which is outfitted with an IQAir hospital grade air filtration unit. Virus particles are 0.03 microns in size. Our filtration unit is tested and certified to filter 99.5% of all particles down to 0.003 microns - this is 100 times smaller than virus particles.
