Pre-Filters

First, it’s important to know that almost all portable air conditioners come standard with pre-filters, which reduce large-sized microbes, dust and pet hair. You can wash and reuse these pre-filters and it’s rare that they need to be changed. So why do you need other filters? The cleaning benefits of pre-filters are minimal as they only capture the largest microbes in the air. They’re also not an effective solution for asthma and allergy sufferers, nor do they remove undesirable odors from the air. For cleaner air, you will want to consider a different option.
