Frequently Asked Questions (FAQS)
When should I change my air filter?
Determining when to replace your air filters depends on the air quality levels you wish to maintain indoors. Although Design Filters are designed to last up to 90 days, there are circumstances where you might need to change them more frequently. Various factors influence the ideal time to replace your air filter. For individuals with allergies or asthma, a new filter can significantly enhance indoor air quality. Households with pets or smokers should consider changing air filters more often to ensure fresher air.

How do i change out my air filter?
Air filters can be found in vents on your interior walls or ceilings, often concealed behind a cover that may be white or painted to blend in. To replace it, open the cover by pulling the lever or latch, remove the old filter, and insert a new one.
For filters located in the AC handler, first turn off your system for safety. Locate the handler unit, typically found in a utility closet or basement. Open the access panel, remove the old filter, and slide in a new one.

How often should I change out my air filter?
Generally, it’s advisable to replace your air filters every 90 days. However, several factors can influence how often you should change them. For households with smokers, vapers, or pets, it’s beneficial to switch out the filters every 60 days. If someone in your home suffers from allergies or asthma, consider changing the filters monthly to maintain optimal air quality. Using a filter with a higher MERV rating can also help in these situations.

What happens if the air filter is backwards or installed incorrectly?
Air filters are designed with a specific direction for airflow to ensure optimal filtration. When installed correctly, air passes through the porous side first, allowing the tight mesh weave to capture and absorb incoming particles efficiently. However, if the filter is installed backwards, the air struggles to pass through the dense mesh, causing the system to work harder. This not only reduces the efficiency of air filtration but also increases energy consumption, leading to higher utility bills. Additionally, the strain on the system can result in potential mechanical damage over time.

Will a dirty air filter affect my AC?
Yes, a dirty air filter can significantly impact your AC system over time. As an air filter collects dust and debris, it becomes less efficient, causing your AC to work harder to circulate air. This increased strain can lead to higher energy bills and potential wear and tear on the system. The lifespan of an air filter depends on various factors, including the type of filter, its material, the size of your home, and your daily habits. Filters with higher ratings, such as those using the FPR (Filter Performance Rating) or MERV (Minimum Efficiency Reporting Value) systems, typically last longer and perform better.

What happens when the AC filter is dirty?
A dirty air filter clogs up with dirt and debris, making it difficult for air to pass through. This restriction forces your AC system to work harder, consuming more energy and raising your utility bills. Over time, the reduced airflow can cause the air inside your home to become stagnant and less clean, as the system struggles to bring in fresh air. This not only affects indoor air quality but also puts additional strain on the AC unit, potentially leading to mechanical issues.

Are AC filters important?
Yes, AC filters are crucial for the proper functioning of any air system. Air systems cannot distinguish between clean and dirty air, so filters play a vital role in ensuring that the air entering your system is purified. Without effective filtration, the air coming from outside can bring in dust, debris, pollutants, and allergens, compromising indoor air quality and potentially harming your AC unit.

What is the proper MERV filter for me?
Choosing the right MERV filter depends on your specific needs and circumstances. MERV (Minimum Efficiency Reporting Value) ratings range from 1 to 20, indicating the filter’s ability to capture particles of different sizes. For most residential settings, a MERV rating between 8 and 13 is ideal, as it effectively captures dust, pollen, mold spores, and pet dander without overly restricting airflow.
If you have allergies, asthma, or other respiratory conditions, a higher MERV rating (between 11 and 13) is recommended to improve indoor air quality. For homes with smokers, pets, or in areas with high pollution, a higher MERV filter can also be beneficial. However, be mindful that higher-rated filters may require your HVAC system to work harder, so ensure your system can handle it.

What happens if I run my AC with no filter?
Running your AC without a filter can lead to several issues. Without a filter, dust, dirt, and debris can freely enter your system, causing buildup on the coils and other components. This can reduce the efficiency of your AC, making it work harder to cool your home and increasing your energy bills. Over time, this buildup can cause mechanical problems, leading to costly repairs or even system failure.
Additionally, running your AC without a filter can significantly reduce indoor air quality. Pollutants, allergens, and other particles can circulate freely throughout your home, which can be particularly harmful to individuals with allergies or respiratory conditions.

How do I properly measure my AC filter?
To ensure you purchase the correct replacement, follow these steps to measure your AC filter:
- Turn Off Your System: For safety, switch off your HVAC system before removing the filter.
- Remove the Existing Filter: Carefully take out the current filter from its slot.
- Check the Dimensions: Most filters have the dimensions printed on the frame. If the measurements are not visible or the filter is too dirty, measure it manually.
- Measure the Length, Width, and Depth: Use a tape measure to determine the length and width of the filter. Measure from edge to edge. Then, measure the depth (thickness) of the filter. Filters typically come in standard depths like 1 inch, 2 inches, and so on.
- Note the Nominal Size: Filters are often labeled with nominal sizes (e.g., 20x25x1). This size can slightly differ from the actual measurements, so if you measure an actual size of 19.5 x 24.5 x 0.75, the nominal size is likely 20x25x1.
- Buy the Correct Replacement: Use these dimensions to purchase a new filter. Ensure it matches the nominal size for proper fit and efficiency.
