For quite some time I felt love the air quality in our condo was never great enough. I changed the air filters officially, but that didn’t seem to be enough. I even made sure to have the ductwork plan cleaned every single year. Then one afternoon, our wife came condo & told me she had a special present for me. This is not something she commonly does, so I was intrigued. I couldn’t suppose it when she pulled out a current UV air purification system. I had study about the UV air purification systems & I believe that they kill harmful bacteria & viruses! On top of that, they supply excellent air quality mostly thanks to the HEPA air filter that they use. The UV air purification system works with a prefilter as well so you can change that filter & allow your HEPA air filter to last much longer, but when we turned on the UV air purification system, it was love a dream to me. The air quality had never been so great & suddenly I was feeling better than ever. I actually labor from condo so I couldn’t wait to use it in our office as I was doing work. Something that has consistently bothered me is seeing any kind of dust in the air, because you believe you are breathing that stuff in your lungs. I have been seeing dust regardless of how much I would dust. When I put the UV air purification system in our office, soon all of that dust I used to see was gone. I am loving this UV air purification system!
