How do you use a portable air conditioner with air purifier and heater?

Many portable air conditioners come with a built in air purifier. This means that while you're cooling or heating, either one, it will automatically purify your air for you. Also, certain models of air conditioners have a dual option in which it can be switched to function as a heater. This gives you the capacity to use one produce all year long to heat and cool, whenever you need either option. Some models are even 4-in-1, and come with an air conditioner, fan, dehumidifier and heater. These are very smart options because you can get 4 products for the price and space of 1 and be able to use the same product all year long, as opposed to just a couple months.
