How to Find the Perfect Air Filter for Your HVAC System

When it comes to replacing the air filter in your HVAC system, it's essential to make sure you get the right size. An incorrectly sized filter can cause damage to your system, reduce its effectiveness, and increase your energy bills. To guarantee you get the perfect air filter, here are some tips to help you out. The first step is to measure the length and width (L x W) of your old filter.

If the filter is not a square, the smallest measurement will be the first. This is the simplest and quickest way to determine the size of the new air filter. Most filters have a side size and the length, width, and depth are measured in inches. In addition to the size, you'll need to determine the proper MERV rating for the air filter before you can replace it.

The MERV rating determines the effectiveness of the air filter in removing particulates from the air, and the higher the rating, the better it will be at this job. When you buy an air filter online, it's important to know that air filters come in two sizes; you need to understand the nominal size (which is a round size often used to label the filter) and the actual size. If your filter doesn't have the actual dimensions on the outside of the filter, you can measure it to get the correct dimensions. Forcing an incorrectly sized filter can cause it to warp, damage, or reduce its ability to function properly.

Worse, incorrectly sized air filters can place excessive stress on your air conditioning system, damage it, and increase energy bills. Neither of these options is a good fit for your health or home, so make sure you have the right size air filter. There are thousands of sizes of air filters available, and manufacturers of heating, ventilation and air conditioning systems often make it as complicated as possible so that you have to pay for expensive replacement parts. But with a few simple steps, you can make sure you get an air filter that fits your system perfectly. The first step is to measure your old filter's length and width (L x W).

If it's not a square shape, take note of the smallest measurement first. This will give you an idea of what size air filter you need. Next, check for a MERV rating on your old filter. This rating determines how effective an air filter is at removing particulates from the air. The higher the rating, the better it will be at this job. When buying an air filter online, remember that they come in two sizes; nominal and actual.

The nominal size is usually round and used for labeling purposes while actual size refers to its exact measurements. If your old filter doesn't have its actual dimensions on it, measure it yourself. Finally, make sure that you don't force an incorrectly sized filter into your HVAC system as this can cause warping or damage. It can also put excessive stress on your AC system and increase energy bills. To avoid these issues, always make sure that you get an air filter that fits perfectly. Finding an appropriately sized air filter for your HVAC system doesn't have to be difficult.

With these tips in mind, you'll be able to find one that fits perfectly and keeps your home healthy and comfortable.
