Do you need to replace the air filter in your home but don't know what size to get? It's a common problem, but it's easy to find the perfect air filter if you know how to measure and understand the dimensions. Poorly sized or incorrectly installed filter frames can cause air leaks, significantly reducing filter efficiency. Here's a guide to help you find the right size air filter for your home. The first step is to measure your existing filter.
You can use a measuring tape to get the size of your existing filter. If your air conditioning system has an air filter, you can check its size to make sure you can get the right replacement. However, it needs to fit snugly into the air filter compartment, leaving some space around the edges. Once you have the measurements, round to the nearest inch to get the nominal filter size, which is the measurement you'll use when buying a filter. Air filters have a MERV rating, which measures how effectively they filter small particles from the air.
If the filter is too small, it will come loose and some of the air (and debris) will not pass through the air filter. If that doesn't work, you may be able to find the proper dimensions of the air filter in your HVAC manual. Here's a fun fact: 70% of what Filterbuy sells is out of the 10 most common air filter sizes.Finding the right size air filter for your home doesn't have to be difficult. With this guide, you'll be able to measure and understand the dimensions of your existing filter and find a replacement that fits perfectly. This will ensure that your air conditioning system is running efficiently and effectively.
How To Measure Your Air Filter
Measuring your existing air filter is essential for finding a replacement that fits perfectly.To do this, you'll need a measuring tape or ruler. Start by measuring the length and width of your existing air filter. Make sure to measure from end-to-end and side-to-side, including any flanges or frames. Once you have these measurements, round them up or down to the nearest inch. This will give you the nominal size of your air filter, which is what you'll use when shopping for a replacement.
Understanding MERV Ratings
Air filters come with a MERV rating, which stands for Minimum Efficiency Reporting Value.This rating measures how effectively an air filter can remove small particles from the air. The higher the MERV rating, the more effective it is at filtering out particles like dust mites, pollen, mold spores, and pet dander. When shopping for an air filter replacement, make sure that it has a MERV rating that meets or exceeds that of your existing filter. This will ensure that your new air filter is just as effective as your old one.
