When it comes to air filters for apartments, there are a few standard sizes that are most commonly used. These sizes are typically listed in width x height x depth in inches and it is important to make sure you get the right size filter for your apartment, as an incorrectly sized filter can cause damage to your air conditioning system and increase energy bills. The industry standard for air filters is MERV (Minimum Efficiency Reporting Value). When replacing your air filter, make sure it is slightly smaller on each side of the groove in the filter housing, so that it can be easily slid in and out.
If the filter is too small, some of the air and debris will not pass through the filter. You may not be able to find the size of air filter you need at a local home improvement store. In fact, 70% of what Filterbuy sells is out of the 10 most common air filter sizes. Thicker air filters with larger folds don't need to be replaced as often, but they can be more difficult to find.
If you can't find the right size at a store, you may be able to find the proper dimensions of the air filter in your HVAC manual. Beyond finding the right size air filter for your apartment, it's important to change it regularly for convenience and cleanliness. If you don't change your air filter regularly, you may be breathing in dirty air. When shopping for an air filter for your apartment, it's important to know what size you need.
You should also consider the MERV rating and thickness of the filter. It's also important to remember to change your air filter regularly for optimal performance and cleanliness.
