Custom air filters simplify the process of finding the right fit for your AC & furnace system. This guide will help you accurately measure your filter space, select the most suitable filter type, and understand MERV ratings.
Precision Measuring: Ensuring the Perfect Fit
An air filter’s effectiveness is all based on its perfect fit. Start by measuring the height, width, and depth of your filter slot with a tape measure, all three measurements are important. Measure the slot rather than an old filter, as the size may be different from what’s printed on the filter’s frame. For the best fit, slightly under-measure to accommodate the filter’s flexibility, which allows it to adjust to the slot without forcing it. The ‘actual size’ of an air filter will normally be about half an inch less than the listed size. So the ‘actual size’ of a 20x25x1 air filter, will be 19 ½ x 24 ½ x ¾. The goal is a balance between a snug fit and easy installation, this will make your filter work effectively and make installation easier.
Measurement Tips for Accuracy
Double-check your measurements to avoid mistakes. A metal tape measure is best for its precision over a fabric tape, which can stretch or bend. Also, consider environmental factors like humidity and temperature that might change the dimensions of the filter slot over time. If uncertain, consulting with a professional can save time and ensure the best performance of your air filter.
Selecting the Right Filter Type
Understanding the differences between each filter type is very important when choosing a custom air filter.
– Pleated Filters have a synthetic media that is pleated so that it increases the surface area of the filter without making the air filter bigger. This way the filter design can catch particles like dust, pollen, and mold, all while keeping a strong and steady airflow and reducing the strain on your HVAC system. This filter is great for residential and commercial buildings.
– Pure Carbon Filters are made specifically for removing odors and volatile organic compounds (VOCs). These filters use activated carbon to absorb and get rid of odors from your home like cooking smells, pets, and smoke. These filters are great for homes where odors or chemicals are bound to happen, this filter will help keep your home smelling fresh.
– Pleated Plus Carbon Filters combine the benefits of regular pleated filters and activated carbon filters. These two filters time combined in one capture a wide range of particles and odors, making this perfect for your home or your business. This filter not only improves your indoor air quality but also helps maintain a comfortable atmosphere for you and your family.
Each of these filters offers great benefits for you no matter which one you choose. Buying these filters is easy with the right air filter company. But keep in mind the MERV ratings when choosing an air filter for your home.
Installing Your Air Filter
Installing an air filter really doesn’t have to be hard. Here is the simplest steps to install your custom air filter correctly.
Location
The first thing you need to do is find where your furnace filters are in your system. Most A/C furnace filters are located in the ceiling or in the walls. Some could be in your furnace box, your attic, or even in the basement. Once you find out where it is don’t forget it! You’ll need to remember in a few months when you replace this air filter.
Turn Off the HVAC
You need to make sure you do this next step, it is very important. Turn off the HVAC system to stop the airflow. You can’t replace an air filter with the air still flowing. If you don’t you’re at risk of an electric shock or unfiltered air going through your home. To turn your HVAC system off look for a switch either on or near your furnace. It will look like a light switch.
Switch the Air Filter
When you remove the old dirty air filter be careful not to leave any dust behind that could go back into your HVAC system. Before you fully remove it look where the arrows are pointed, this is important for installing a new air filter. When putting in the new air filter write the date you installed it so you know how old it is when you replace that one. There will be a spot on the side for you to put the date. Now remembering where the arrows were pointing, install the new air filter the same way. Some custom air filters might not have the arrows visible, so the air flows from the side without the metal mesh through to the side with the metal mesh.
Now that you have properly installed an air filter go breathe in the fresh air in your home. But don’t forget, you’ll need to replace it in 3 to 6 months depending on your household.
