When our fiance plus I were invited to have lunch at our sister’s house, I didn’t think anything could go wrong. Every one of us were honored to have lunch with our sister plus her hubby. Well, when the people I was with and I got there, our fiance plus I started coughing plus the people I was with and I could tell that the air quality was not truly good. I tried not to say anything for a long time. I figured if the people I was with and I could just make it through the lunch, the people I was with and I would be golden, however of course, our fiance was so uncomfortable, I knew that I had to say something. I ended up talking with our sister’s hubby plus I asked him when was the last time he had the air filter changed plus the ductwork system cleaned. He said he swings the air filters roughly every 3 months, but he doesn’t use the lavish air filters. I went with him to the basement plus he showed myself and others the air filters he uses. I couldn’t feel it, he was using the air filters that are cheap plus need to be changed once every month. It’s no wonder the air quality was bad. I told him it was not a wonderful proposal to use those cheap air filters. He asked myself and others if I knew what kind of air filters he should get, plus I told him that I would show him, however so the people I was with and I went to the store while our fiance plus our sister were talking. Every one of us entirely ended up getting some HEPA air filters which are fantastic for improving the air quality, and as a matter of fact, you can’t find a better air filter for your Heating plus A/C system! It didn’t even take long after the people I was with and I installed the HEPA air filter for the air quality to improve dramatically. Even our sister was gleeful with the change! Every one of us ended up having a absolutely nice lunch because of the improved air quality.
