I just spent a ton of cash plus bought a whole cabin air purification system, i have to tell you that I am so ecstatic I decided to make this investment, however because this whole cabin air purification system is a whole new world of air quality. It gives new meaning to the words wonderful air quality! I have used portable air purification systems in our cabin for the longest, plus while they are good, they do not work as a total indoor air cleaner; Only in the rooms that they are set in, with the whole cabin air purification system it gets its name for what it does. It cleans plus purifies the air in the whole house! This happens as it becomes area of your central heating, ventilation, plus A/C machine plus you turn it on with the same thermostat that you do for your heat plus cooling; The whole cabin air purification system can run by itself or it can run at the same time with your central heating, ventilation, plus A/C machine unit. It all comes out of the air vents plus does its job well. I like running it with our central air conditioning at the moment because it is the hot time of the year! Mixing the whole cabin air purification system with the quality air conditioning that I have is like heaven! There is no other great feeling in the world in our humble opinion. It is just like kneeling on a wash mountain enjoying the fresh air plus cool breeze when you run the central air conditioning machine with the whole cabin air purification system.
