A couple months ago, my best friend called me with a problem. His wife had been having a lot of problems with her breathing. He ended up taking her to the hospital to be checked out. They told her she had an infection in her lungs that came from allergies. She had never suffered from allergies before, but the doctor said that prolonged exposure to allergies can cause allergies to form. Now he had to find out what was causing her allergies, so he could get rid of it. We checked everything, and all we could find was that there was a lot of dust in the air. After a lot of investigation on the internet, he and I came up with the same conclusion. We found out about these air purification systems that can be installed directly into the HVAC system. The air purification system would be able to clean the air and help with the dust and allergens that are in the air. He decided to call the HVAC company to get more information and to make an appointment to have the air purification installed into the HVAC system. The only snag with the idea was that it was really expensive. I was going to offer to help him purchase the air purification system, but he had already gone to the bank to secure a loan. I’m glad he was able to purchase the air purification system. The difference it made in his air quality and how his wife is feeling, has made me reconsider whether I wanted to buy one and I put it on my to-do list for the summer.
