When it comes to air filters, it's important to know the right size for your HVAC system. The filters are labeled with three-part dimensions: length, width, and depth or thickness. Honeywell, Hunter, and Whirlpool have several models of room air purifiers available, so it's important to check compatibility before buying a replacement one. If not, the best way to determine the size you need is to measure the filter that is already there, assuming it's the right size. We recommend that you start looking for a replacement air filter by reducing the depth of the air filter.
This rounded measurement is called the nominal size and is used to match the correct filter to the corresponding air filter slot. These commonly sized air filters are the sizes that can normally be easily found in large stores such as Home Depot, Walmart, and Lowe's. In addition, if there is any resistance to air flow caused by the use of a filter that isn't the right size, it can cause unnecessary strain on the HVAC unit itself, which could damage the system equipment and increase your energy bills. Changing your HVAC filter is just one part of the routine maintenance you must perform on your system. Unfortunately, that's not the case: there are standard sizes of approximately 20 inches for air filters and none have the same measurements.
The gaps will allow dust, dirt, and germs to bypass the filter and potentially re-circulate to the air in your home. Here's an interesting fact: 70% of what Filterbuy sells doesn't exceed the 10 most common air filter sizes. If you're using a room air purifier and need to replace the filter, it's important to find the right size replacement HEPA filter. Most air conditioning and HVAC units use standard size filters, but some require a custom-sized air filter to be purchased and installed. If you have a system that uses a whole house filter, you may have an option from MERV 8 to MERV 16, depending on your HVAC system.
If you have a system that has the option of a high-efficiency MERV 15 filter, such as Bryan and Carrier offer germicidal air purifiers. Each brand makes filters with slightly different actual sizes, so check the exact measurements of each filter before buying them. We recommend removing the existing filter and measuring it to confirm its actual dimensions. This will ensure that you get an accurate replacement that fits perfectly in your HVAC system. It's also important to note that if you don't replace your air filters regularly enough, it can lead to poor indoor air quality and higher energy bills. When it comes to finding the right size AC filter for your home or business, it's important to do your research and make sure you get one that fits properly.
Not only will this help keep your indoor air clean and healthy but it will also help keep your energy bills low.
