1. How do I measure my air filter to ensure I get the right size?
Answer: To measure your air filter, simply measure the length, width, and depth (thickness) of the existing filter in your HVAC system. Round up to the nearest inch if the measurement isn’t exact. For example, a 19.5 x 24.5 x 1 inch filter would be rounded up to a 20 x 25 x 1. This rounded measurement is called the “nominal size.”
2. Can I order a custom-sized filter?
Answer: Absolutely! We offer custom-sized filters for customers with unique HVAC dimensions. Simply provide the exact measurements you need, and we’ll make a filter that’s the perfect fit. Look for the custom size option on our site, or reach out to us if you have questions. This can be done here: https://customfiltersdirect.com/products/custom-air-filters
3. What’s the difference between nominal size and actual size?
Answer: The nominal size is the rounded measurement commonly listed on the filter, like 20 x 25 x 1. The actual size is the exact dimensions (often a fraction of an inch smaller) that ensures a snug fit within your HVAC system. Both are important to know, but filters are generally listed by their nominal size.
4. My filter slot is an odd size. What should I do?
Answer: No problem! Odd-sized filter slots are actually common. You can use our custom sizing options to order a filter tailored to your specific dimensions. Just measure carefully and enter the measurements when ordering.
5. How do I know what thickness my filter should be?
Answer: The thickness, or depth, of your filter is just as important as length and width. Common thicknesses are 1, 2, and 4 inches. Check your HVAC system’s manufacturer recommendations or look at the size on your current filter to confirm the thickness you need.
6. Do custom-sized filters work as well as standard sizes?
Answer: Absolutely! Our custom-sized filters are made from the same high-quality materials as our standard sizes, ensuring they deliver the same excellent filtration and performance.
7. Can I get a pleated filter in any custom size?
Answer: Yes, we offer pleated filters in custom sizes! Simply choose the pleated filter option and provide your desired measurements. However, please note that we don’t make filters with a nominal size larger than 4 inches. Pleated filters are a great choice because they trap more particles, thanks to their increased surface area, giving you cleaner, fresher air.
8. Can I change my filter size if I ordered the wrong one?
Answer: If you accidentally ordered the wrong size, contact us as soon as possible. We’ll do our best to adjust your order if it hasn’t shipped yet. For shipped orders, we can guide you through our return or exchange options.
