3 Most Important Things to Remember While Buying Home Air Filters Minnesota

 

Are you thinking of buying an air filter for your HVAC system? Then you should know a few important things before you bring home one. From MERV rating to types of filters, here’s a brief detail on some of the points that you need to keep in mind.

 

MERV Rating:

If you are not aware of the term, then you should know that MERV rating is the Minimum Efficiency Reporting Value which helps you understand how good your AirGuard air filter is to prevent debris and dirt particles from getting into your system. Always choose a filter with higher MERV rating. This ensures that the filter can absorb smaller airborne particles and is also good for your HVAC system.

 

Where to Install:

Many people install their air filters in the HVAC system itself. However, you can install in the return vents. Some homes have return vents that require air filters. Return vents don’t blow out air, rather they suck in. If you look closely your vent already has an old air filter. So, if you want to replace it, you can measure the size of the old one and buy accordingly.

 

Should You Buy Washable Filters:

If you do some research before buying one, you will find that most of the washable air filters are electrostatic in nature. It means that they use electricity to capture particles. It is a preferable choice for many as it is environment friendly and last several years. However, the electrostatic properties are not effective when it comes to absorb tiny particles that creates problem for people having asthma and allergies. So, if you want an air filter with high MERV rating, then a washable filter is not option. Also, it can be troublesome to wash off the filter and again install it from time to time.

Now, there are disposable filters with electrostatic properties available in the market. The electrostatic charge in these dust-lock home filters help trap small particles and keep them stuck to the filter once they are trapped. You only find them with high MERV rating as well. 

No matter what filter you choose for your HVAC system, make sure to replace them whenever it’s required.
