What You Need to Know About 20x20x1 HVAC Filters

When it comes to HVAC filters, size matters. The 20x20x1 filter is a popular size for many homes and businesses, but it's important to understand the real size of the filter and how it can help protect your heating and cooling equipment. When measuring for a 20x20x1 filter, it's important to use the "real" size, as shown by a measuring tape. This is different from the nominal size, which is often used when creating a filter.

The MERV 8 HVAC air filter is designed to protect your heating and cooling equipment from most of the particles in the air. This type of filter can help reduce energy costs and maintain superior indoor air quality, especially if you have pets, children, or people with allergies in your home or business. It's important to replace filters more frequently in these cases.
