Are you wondering what size air filter you need for your home? You're not alone. Many homeowners struggle to determine the right size air filter for their HVAC system. Fortunately, it's not as complicated as it may seem. In this article, we'll explain how to measure and find the right size air filter for your home.
In most cases, you can use the closest standard size. Most air filters have their size printed on the side of the frame. The length, width, and depth of the filter are measured in inches. For example, it will say something like “16x25x1”, where 16 is the length, 25 is the width, and 1 is the depth.
To find the size of pleated filters used in your home, you don't need to look any further than your existing filters. In the outer frame, you'll see at least one set of numbers. If you see two sets of numbers, the filter size needed to request replacements is the nominal size, not the actual size. You can ignore the actual size printed on the filter for this task, since the nominal size is the set of numbers needed to order new filters.
Most air filters are located on the right or bottom of the unit and can be easily removed from the slot.Basically, when you take measurements of an air filter, you just need to round the nearest inch to find the dimensions of the filter you need to buy. If the filter is too large, it won't fit into the filter slot and you won't be able to replace the cover.In addition, if there is any resistance to airflow caused by the use of a filter that is not the correct size, it can cause unnecessary stress on the HVAC unit itself, which could damage the system equipment and increase your energy bills.When you change oven filters, the first thing you want to do is to know what size oven filter you have. You'll need to do this if your oven is missing the air filter and you don't know what size the air filter is supposed to be.From sizes to types, grades and more, here's everything you need to know about air filters.
How To Measure Air FiltersThe first step in finding out what size air filter you need is measuring your existing filter.
For example, it will say something like “16x25x1” where 16 is the length, 25 is the width, and 1 is the depth.
Types Of Air FiltersThere are several types of air filters available on the market today. The most common types are disposable fiberglass filters and pleated filters. Disposable fiberglass filters are made from spun glass fibers that trap dust particles as they pass through them. Pleated filters are made from a combination of paper and synthetic fibers that trap dust particles more effectively than fiberglass filters.
Grades Of Air FiltersAir filters come in different grades or MERV ratings that indicate how effective they are at trapping dust particles.
The higher a filter's MERV rating, the more effective it will be at trapping dust particles.
