Using an improperly sized air filter in your HVAC system can have serious consequences. The biggest concern is that it may not effectively prevent dust buildup on the motors and blowers, leading to dirty ovens, decreased performance, and costly repairs or replacements. Before purchasing a replacement air filter, make sure to check the size of your existing one. If it's too large, it won't slide properly in the slot, and if it's too small, it won't cover the entire space and may allow dust and dirt to pass through.
If you're unsure of the filter size you need, consult the manufacturer's specifications or ask your HVAC technician for help. Bending the filter can also be a problem as it results in an imperfect seal. Air will filter through and around the curve, bypassing the filter completely. This causes dirt and debris to build up on the fan, slows down airflow, degrades performance, decreases air quality, and generally creates a big mess that you'll have to pay to repair or clean it later.
An incorrect air filter can also reduce HVAC efficiency and increase heating and cooling costs. If the filter is too dense, the heater or air conditioner may need to run longer to counteract increased air resistance. Too small a filter allows contaminants to build up on critical components, which impairs performance. The right filter will improve your health and comfort without sending utility bills through the roof.
Installed inside existing ducts, they are much more effective at cleaning the air than conventional filters. Filters don't need to have a “hermetic seal”, but you should be able to easily install and uninstall the filter effortlessly, and the filter should not be small enough to move freely within your unit. If you can't find a standard-size filter within that parameter, you'll need to order a custom-sized air filter. It's there to protect your heating, air conditioning, heat pump, or whatever system is installed in your home.
The right size will go a long way in saving money for future repairs, as dust and contaminants will be properly sealed if the filter fits snugly. Using the wrong air filter can cause numerous problems with the HVAC system, including lower indoor air quality and higher energy bills. It will also cause poor indoor air quality, which is especially bad for those who have respiratory problems such as asthma.
