How To Measure Air Filter Dimensions Right
The air filter must fit perfectly into your equipment slot, whether it's an air conditioning system, a furnace, or a heat pump. So here is the step-by-step to find the right size of your air filter.
Turn off the HVAC System: Before replacing your air filter or doing any maintenance, always turn off your HVAC system to stay safe and avoid damaging it. If the system is running, removing the filter could spread dust, dirt, or debris around.
Remove the air filter: To remove the air filter, begin by locating the filter compartment in your HVAC system, which is typically near the return air vent or inside the unit. Once you’ve found it, carefully slide out the old filter. Before removing it, make sure to note how the filter is positioned so you can easily install the new one in the same way.
Check For Labels: Many air filters have a label on the side or frame with the dimensions. If your filter has one, you can easily find its length, width, and height. These measurements are usually in inches and help ensure a proper fit for a replacement filter. Check both the nominal and the actual size, as there can be slight differences. If the label shows the material and type of filter, make sure to buy the same type to fit your system properly.
Measure Manually: If your air filter doesn’t have a label, use a tape measure to manually check its length, width, and height. Then, measure the depth, which is the distance from the front to the back. Double-check your measurements for accuracy. If you're unsure or unable to measure it, contact a professional to help you find the right custom-sized filter for your specific needs.
Why Custom Air Filters Are Necessary For HVAC's With Odd-Sized Returns
Air filters can't be adapted to fit the return slot. Therefore, the right size guarantees that the HVAC system works perfectly, resulting in the following benefits:
Improved Air Quality
Custom-sized filters are made to fit your HVAC system properly, so there are no gaps around the edges. This prevents air from passing through without being filtered, which helps keep dust, allergens, and other particles out of the air. Our filters can trap even the smallest particles and are also helpful for people with breathing problems, asthma, or allergies. In areas with pollutants like bad smells or harmful gases (such as chemicals in kitchens or workshops), custom filters can use special materials like activated carbon to solve these issues.
Increased Energy Efficiency and Lower Utility Bills
Custom filters help your HVAC system run more efficiently by providing the right fit, reducing strain on the system and lowering energy consumption. A filter that fits properly helps the blower motor run smoothly and allows air to flow easily, so the system doesn't have to work harder. Using a filter that’s too small or too large can restrict airflow, causing the system to consume more energy. The right filter material and thickness will trap the needed particles without getting clogged too fast, which means you'll need to replace it less often and save on maintenance costs.
Longer Lifespan of HVAC System
Properly fitted filters reduce the wear and tear on your HVAC system, extending the life of your equipment by preventing debris buildup and improving airflow. When filters don’t fit properly, they can increase airflow resistance, putting extra strain on the system’s parts. Without the right filtration, dirt and debris can build up on important components like the evaporator coils and blower motors, leading to damage and costly repairs. By using custom air filters designed for your HVAC system, you ensure it runs efficiently, reducing the chances of sudden breakdowns and downtime. Custom filters help maintain smooth airflow and prevent unnecessary strain on the system.
