I went to my friend’s house the other week and the house really smelled pretty bad in there for some reason! My friend even noticed it, and we were talking about it. So, the next day after this, my friend called me up and told me that it was because there was so much stale air in the house and that it needed a good cleaning as well as he had to go out and buy an air purifier. It took a lot of investigating to figure out that an air purifier is what was needed to correct the situation. My friend had said that he was looking into an air purification system for his entire house, also known as a whole-home air purifier. But when he called up the heating and cooling company that we have in town, he found that the price was way too expensive. So, the next best thing was to go for a regular air purifier that you could buy at the store and plug into the wall. The air purifier he got was pretty small, but very portable. He plugged it in right in his living room and made it direct the air from the living room, into the hallway, then right into the bedroom. Within a few days, thanks to the air purifier, his house no longer had that bad stale smell that it had the day I went to visit him. After this happening and getting to experience this myself first hand, I decided to go to the store and buy an air purifier myself. It made a huge difference in my indoor air quality in my own home.
