One of the most important HVAC components of an AC unit is the air filter. It's the part that keeps debris and dust from entering the cooling system. If you're buying one for the first time, this advice can point you in the right direction.
Get the Correct Size
Sizing is one of the most important attributes of an air filter. Getting the wrong size — even just slightly — can result in installation and performance issues. You can easily avoid them by taking the right precautions.
The easiest thing you can do is actually taking measurements of your air filter's housing unit. Once you have these figures, you'll have a better idea of what filter size to select. Or if there is already a filter in the housing unit and you're replacing it, take it out and look on the side for dimensions.
Consider a Reusable Design
When you buy a standard air filter, it may only last a couple of months. Then when it gets too dirty, you'll have to throw it away and find a new one. This cycle can make your filter costs go up. It thus might be better to get an air filter with a reusable design.
You can then reuse the filter a couple of times before having to replace it, helping you save a lot of money over the years. The only thing you'll have to do with this type of filter is to pat it down from time to time before putting it back in place.
Look for High-Quality Build
When it comes to air filters for AC units, you want to ensure you get filters that are high-quality. They will then last a lot longer and do a better job at keeping dirt and debris out of your cooling system. Even if you have to pay more for a high-quality filter, these extra costs are worth it in the end.
High-quality filters are ones that are very thick. They'll be able to screen things a lot more effectively than thin filters. Filter brand can also dictate quality. If you don't know what filter brands are great, you can search customer reviews to find out.
The air filter is such an important HVAC part for your AC unit. If you're getting a new one, take your time weighing impactful factors. You can then maximize this investment and keep your AC unit working great for a long time. Visit an HVAC supply store to learn more.
