It is possible to run an air conditioner without a filter, but it is not recommended. Doing so for more than 6 to 8 hours can cause serious damage to the air conditioning system and significantly reduce your home's air quality. It is best to wait until you have a replacement filter before running your air conditioner. Running an air conditioner without a filter is worse than running it with a dirty one.
The longer you leave your air conditioner running without a filter, the more likely you are to have problems with indoor air quality. This can lead to an increase in allergy symptoms, respiratory problems, eye irritation, or nose and throat irritation. In addition, dirt and debris can be absorbed by the air conditioning system and returned to your home, remaining and accumulating in the HVAC ducts. Both scenarios can reduce air quality and potentially damage the HVAC system, resulting in costly repairs or replacements.
The most common problem with operating an air conditioner without a filter is the decline in indoor air quality. The air conditioner draws air from the indoor environment and cools it before dispensing it back to the indoor environment. If you don't change your air filter often enough, it will work less efficiently or it may stop working completely because the filters are clogged. Without a filter for the air conditioner, the condensate drain will not be able to perform its function of draining condensation and moisture from the unit.
According to popular belief, the more you use your air conditioner, the more often you'll need to change your air filter. In a situation like this, you should be able to operate your unfiltered air conditioner safely overnight or until the next day, when stores reopen. If you put your hand on the air conditioner's ventilation grille, you may feel a scant amount of cold air coming out or hot air. It is important to note that running an air conditioner without a filter can cause serious damage to the system and reduce indoor air quality. We recommend that you never try to do so and always replace your filter as soon as possible.
