Without an air filter, condensation will build up in the Freon tube of your air conditioning unit, leading to water damage. Debris such as dust and hair can also accumulate in the system, clogging parts and preventing them from working properly. This can cause the air conditioner to overheat and turn off, or even cause permanent damage to the engine. To keep your air conditioner in good condition and make it last longer, it's important to use an air filter and change it regularly. 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.
The Minimum Efficiency Report Value (MERV) rating for an air filter measures how effectively the filter prevents dust and other contaminants from passing through the filter into the air stream. The coronavirus responsible for the COVID-19 pandemic 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 the presence of coronavirus in the 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. It's important to note that there are high-efficiency filters that are designed to filter out small bacterial, mold, and fungal particles, but your standard MERV 8-11 filters will simply block out larger particles of dust, dirt & hair. Either way, oven filters need to be changed regularly so that they can continue to perform their vital function and protect the oven and circulate clean air.
A dirty filter forces the HVAC unit to work harder than normal because it finds it more difficult to draw air. Using an air filter with a MERV rating higher than recommended by the manufacturer of your oven or air conditioner may impair its performance. Another thing that can happen when you neglect your AC air filter is that dirt that accumulates in your system restricts the flow of cold air. Some air conditioning systems are large and complicated, and even finding the filter can be difficult. Regularly changing your air filter is a simple task that makes a big difference for your air conditioner's performance. It's essential for keeping your system running efficiently and preventing costly repairs down the line.
Not only does this help keep your home clean and healthy, but it also helps you save money on energy bills by ensuring that your HVAC system is running at its best.
