When it comes to replacing your HVAC filter, does it really matter what type of filter you choose? Aren't all filters basically the same? The answer is no, they are not all the same. It is important to understand the differences between the various types of filters available and how they can affect your home's air quality and the performance of your HVAC system. The most important factor to consider when selecting a filter is the size. As long as you buy the same SIZE, it doesn't matter what BRAND you use.
The important thing is the filter rating. For example, replacement Honeywell oven filters can be purchased through several filter manufacturers. They are manufactured to the same specifications as the brand name filter. Simply choose a filter size and a MERV rating that meets your needs.
Often referred to as OEM filters or original equipment manufacturers, they are produced by the brand name company. There are also many aftermarket or discounted home air filters available for purchase. So what's the difference? To tell you the truth, the biggest difference you'll see is the cost of HVAC filters. OEM filters are often much more expensive because you pay for one brand.
When comparing the material from which each air filter is made, they will look and feel identical. The only difference you can occasionally see is if the OEM filter material is limited or has a patented design. In its most basic function, an air filter removes impurities such as dust, pet dander, or even bacteria from the air that flows through the system. Not only does this improve the air quality inside your home, but it also protects your HVAC system from potential damage. A wider classification shows that the filter can trap finer particles.
This sounds exceptional, but a filter that traps finer substances can clog faster, increasing pressure on the equipment. If your unit is not designed to work with this model of filter, it may decrease airflow and cause other problems. If you really want to go further, buy 3 different types of filters and take readings with each of them at once in the filter slot. Also think about having a layer of dirt on them. If a clean filter is about to be out of the parameters, chances are that if it is dirty it will go out of specification. Thanks to today's smart home technology, you can even purchase smart filters such as 3M Filtrete smart air filters that use sensors to monitor airflow.
While you should refer to the instructions for your HVAC system and your specific filter for maintenance guidelines, you should generally change filters at least every season, if not once a month. You can check the MERV rating, which is a scale that determines filter efficiency from a low 1 to a high filter index of 20. Most of the time, the filter size is printed on the old filter and can be used as a reference for reordering. However, you can order filters online and in bulk, which can save you money and the hassle of having to go to the store every time you need a filter. When it comes time to replace your HVAC filter, it's important to understand that not all filters are created equal. It's important to consider factors such as size, brand, MERV rating and cost when selecting a new filter for your home or business.
By understanding these factors and selecting a quality filter that meets your needs, you can ensure that your home's air quality remains high and that your HVAC system runs efficiently.
