When looking for an air conditioner and air purifier combo it is important to look at the filters that are offered. Many people tend to just look for portable HEPA air purifiers or air conditioners with HEPA filters, but there are actually four types of portable air filters for conditioners: Pre Filters, HEPA Filters, Activated Carbon Filters, and UV light sanitizers.
Pre-filters are basic air filters that capture large-sized ait contaminants such as hair, dirt, and mold spores. These are important because they will not only help to eliminate pollutants from the air, but they will also keep the inner workings of the AC unit clean and operating at peak performance.
These HEPA filter air conditioning filters are able to capture extremely small particles such as allergens (pollen), dust, germs, dander, and more. HEPA filters are able to capture 99.97% of air particles that are at least .03 microns in size. Air conditioners with HEPA filters will do a great job of cleaning the air in your home.
Activated Carbon Filters
Carbon filters are another effective type of filtration. Carbon filters use immense amounts of surface area to absorb smoke, gases, odors, and more. They will also help capture allergens, dust, mold, and pet dander/hair.
This purification process uses intense amounts of UV light to kill living organisms. A UV sanitizer will kill bacteria, viruses, and dust mites.
Room coverage is another important aspect to consider. Before deciding on the unit, you should know the size room that you want to cool. To measure room size simply multiply the length of the room times the width. This will give you an approximate size that you will need to cool. You can find a single room air purifier or one that works for larger areas. Generally, the smaller the room coverage the more affordable the air conditioning unit.
