What Happens if You Don't Have an Air Filter?

Without a filter, the condensate drain will not be able to drain moisture from the air conditioning unit. This will result in condensation building up in the Freon tube, which will start to drip down the tray and cause water damage to the entire system. Some air conditioning systems are large and complex, making it difficult to even locate the filter. This is important as it protects the oven and keeps the air clean, since the HVAC system does not recirculate allergens.

It is essential to change oven filters regularly so that they can continue to perform their vital function and protect the oven while circulating clean air. An air conditioning system has a filter to prevent dirt and debris from entering the unit and entering the indoor environment. The evaporator coils contain a substance called refrigerant, which absorbs heat from indoor air so that the air conditioning system can return cool air to your home or office. If you run your air conditioner without a filter for more than 6 to 8 hours, it can cause serious damage to your air conditioning system and significantly reduce the air quality in your home.

The lack of a filter will have a huge negative impact on indoor air quality, possibly even causing the spread of diseases or an increase in allergic reactions. Commercial and residential cooling and heating systems need a filter to remove impurities before they suck indoor air into the system and exhaust it back to areas that are supposed to heat or cool. These air filters act as barriers to prevent contaminants from entering the HVAC system or circulating in the air. A dirty filter forces the HVAC unit to work harder than normal because it finds it more difficult to draw air.

Without a filter, the system will suck in debris-laden air and return the same dirty air to the indoor environment, contributing to health problems. Your air conditioner sucks in the air from your home, removes heat from it, and then returns it back inside. Air filters typically have a MERV (Minimum Efficiency Report Value) that determines the type and size of contaminants against which the filter will act. But what happens if you let that time go by a little? Before we talk about WHEN you should change your air filter, let's start with the WHY. The coronavirus responsible for COVID-19 has particles with peaks that measure between 9 and 12 nanometers, which means that an HVAC system or an air purifier equipped with a HEPA filter can effectively reduce its presence in the air.
