Let’s find out everything you need to know about the HVAC filter.
- Choose the Right MERV Rating
One of the most important things you need to consider while choosing HVAC filters is the MERV rating. This rating shows the efficiency of air filters that ranges from 1 to 20.
A good MERV rating helps the HVAC system trap the tiniest substances and to keep away harmful substances and pollutants. To choose the right MERV rating, you must analyze your lifestyle and requirements.
For example, if you have pets and small children at home, then MERV 10 HVAC filters will be the right choice for you. It will enable the HVAC system to capture debris, mold spores, pet dander, and pollen.
If you are not sure which MERV rating to choose, then you may consult professional HVAC maintenance service providers. It will help you get the right recommendations according to your needs.
- Have Measurement of Furnace Filter
While choosing the air filter, you must have the right measurement of the furnace. You can find this filter in the furnace handler and measure the size in length x breadth x height. You may do it by using a simple measurement tape.
After having the accurate size, you need to round up that number because sometimes the required size could be half an inch more. After having the correct figure, buying the filter will be easier for you.
- Choose the Right Filter Type
There are various filters available in the market with different types and sizes. You must know which type of filter to choose, so it can save you time and effort.
Pleated, Reusable, Fiberglass, and HEPA are four different types of filters. Fiberglass is the disposable filter with the lowest rating, and you may have to change it regularly. You may also opt for Reusable filters, but it may attract more mold.
On the other hand, if you want a moderate MERV rating, then you may go for the Pleated filter. It is best suited for typical houses.
If you are willing to make a one-time investment and want the quality filter with the highest MERV rating, then you should choose HEPA filters. These filters are suitable for healthcare facilities as they restrict airflow.
To pick the right filter, determine the size of your HVAC filter and the weather conditions you live in. As already mentioned above, you may consult professional service providers to get the right recommendation for choosing the filter type.
