How to pick a 14x25x1 air filter

When choosing an air filter, you should consider its type, size, model, filtration efficiency, cost, replacement requirements, and your breathing needs. It may seem like a lot of factors but getting it right on each aspect ensures that you and your loved ones can comfortably say goodbye to the pollutants that threaten your well-being and that of your HVAC system. Let’s take a brief look at how the size works in your favor:


The first thing you need to consider is the size of the filter you need.

In most cases, you can refer to the system manual for this information. You can also look at the dimensions of the old filter to guide your decision, or you could measure the space yourself to be accurate. This dimension will ensure that you do not get a size that is too big as this will have to bend, thereby reducing its effectiveness.

You also want to avoid getting a filter that is too small for your space as it will allow particles to make their way into the vents.

Dimensions can be confusing, especially where you are new to buying filters. In this case, you want a 14x25x1 filter, and you may come across a manufacturer stating that a product meets these specs only to find that the figure given is rounded off and is not the actual figure. Where you do not take the time to consider both nominal and real dimensions, you are likely to lose money in the purchase.

Buying a filter gets easy when you get the filter model that suits your space as it is quite hard to mess up the fit in such a situation. However, you do not have to go with the original model, as many aftermarket models can fit your space. You may wonder what the difference between these models is.

Original filters are those made by a specific brand to fits its air systems. Such that company A can bring filters in the market which work for its furnaces, air conditioning, and HVAC systems. In such a setup, it would prove easy to get a filter from company A as the fit will be right. Then there are the aftermarket filters which also work just as well.

These filters are products of other companies, designed to fit air systems of different brands. They feature the same specifications as those made by the original companies, and they offer the same level of quality. The good thing about them is that they are available at low prices, allowing you to save some good money in the end.

When getting the aftermarket filters, it is necessary that you pay attention to the sizes as you want to ensure that you get something that will work for your space. Thus, there is nothing wrong with getting either of the two, and there is no reason why you should limit yourself to one option.

Good luck!
