MERV Air Filters – How They Work and Are They Worth the Money?


MERV air filters are a type of air filter that is designed to remove contaminants from the air. MERV is an acronym that stands for Minimum Efficiency Reporting Value. The MERV rating is a way of measuring the ability of air filters to remove contaminants from the air.

The higher the MERV rating, the more effective the air filter is at removing contaminants from the air. There are a wide variety of MERV air filters on the market, and the price of these filters can vary widely. So, how do you know if a MERV air filter is worth the money?

How Do MERV Air Filters Work?


MERV air filters trap particulates in the air as they pass through the filter. The size of the particulates that a MERV filter can trap depends on the filter’s rating. For example, a MERV 8 filter has much smaller pores than a MERV 16 filter. This means that a MERV 8 filter will trap smaller particulates than a MERV 16 filter. The type of particulates trapped by a MERV air filter includes dust, pollen, mold spores, and pet dander.

MERV Ratings

Different MERV ratings offer different features that can be beneficial for your home. Here are some of the features that you may want to consider when choosing a MERV rating:

  • The higher the MERV rating, the more effective the filters will be at trapping smaller particles. This can be beneficial if you have allergies or respiratory problems.
  • MERV ratings can also be a factor in energy efficiency. Higher MERV ratings will typically result in less air resistance, which can lead to lower energy bills.
  • Some filters with higher MERV ratings can also help to reduce odors in your home.
  • If you have pets, you may want a 14x24x1 air filter with a higher MERV rating to help trap pet dander and other allergens.

Are MERV Air Filters Worth The Money?


It depends on a few factors.

  • The first factor to consider is what type of HVAC system you have. If you have an older HVAC system, it may not be able to handle a high-efficiency air filter such as a MERV 16 or higher. This is because high-efficiency filters can put extra strain on your HVAC system, leading to increased energy costs and premature HVAC failure.
  • Another factor to consider is your budget. High-efficiency air filters, such as those with a MERV rating of 16 or higher, can be quite expensive. If you are on a very tight budget, you may want to opt for a less expensive option, such as a pleated paper air filter with a lower MERV rating.
  • The final factor to consider is your health needs. If anyone in your family has allergies or asthma, you may opt for a high-efficiency air filter with a higher MERV rating to trap more allergens and provide better indoor air quality.

While MERV air filters are more expensive than standard filters, they offer many benefits that make them well worth the investment.
