How to choose an air filter for your home


You should consider the MERV rating system, filtering grade, and flat-panel versus pleated design when choosing an air filter for home from If you’re unfamiliar with these terms, read this article to learn how they work. You can then decide which one is best for you and your family. You’ll also learn about the different types of filters available. If you’re still not sure, we have some tips to help.

MERV rating system

The MERV rating system is a measure of how efficient an air filter can be. MERV stands for Minimum Efficiency Report Value. It is an acronym that stands for Minimum Effectiveness Report Value. It is the efficiency of a filter in reducing the airborne particles. Air filters with lower MERV ratings will reduce the amount of E3 particles in the air by less than 20 percent. MERV ratings are generally higher than those of other filtration levels, and therefore shouldn’t pose a problem to the system.

Filtering grade

There are many types of air filters. HEPA filters are a good choice for people who need high levels of filtration. You should be able select the best filter for your needs. It is important to be aware of your options to ensure that you don’t end with something that doesn’t work as expected.

Clean air delivery rate

An important performance indicator is the Clean Air Delivery Rat (CADR) of an Air Filter. This indicator tells you how efficient an air filter is at removing contaminants. It is calculated by multiplying the air flow rate in the room by the amount of air it cleans per hour. A good filter should have a CADR at least 300. If it is only 90 percent efficient, it will only produce clean air at half that rate. That’s why you’ll want to pay close attention to this figure.

Pleated vs. flat-panel design

In a duct, a pleated air filter offers a higher filtering surface area than a flat-panel design. It also typically uses synthetic or cotton-poly blend filter media with a MERV rating of 6 to 11. Pleated filters have a higher efficiency level, offering 35-85 percent efficiency in capturing particles in the 3 to 10 micron size range. However, they are more expensive due to their higher efficiency.

Cost of new air filter

There are many factors that affect the cost of an air filter replacement. You should keep in mind that the cost will depend on the type of filter that you need. If you live in a city with thick smog, you may need to replace it more often.
