Air Exchange Rates

One of the most important aspects to consider is how quickly the unit is able to clean the air. While the size of the unit will determine the amount of air that is capable of moving through the system, you do want to choose one with a higher exchange rate. Some affordable models are capable of filtering the air 4 or 5 times per hour which can dramatically reduce the number of allergens and pollutants.



There are several types of filters and each has its own advantages. HEPA filters are generally considered the most effective and some may only need to be replaced every few years. Reusable filters can be cleaned and reused, but this can often be time consuming. There are also inexpensive filters that need to be replaced monthly, but these are not always effective at removing all of the impurities from the air.



Air purifiers can also include convenient extra features that make it more efficient and easier to use. Indicators that alert you when it is time to clean the filter are always convenient, along with a sensor that will automatically adjust the cleaning speed depending on the number of pollutants in the air.
