When it comes to choosing the best air filter for your home, you need to choose a merv 13 that can effectively remove all harmful particles. There are many filters on the marketplace, so it is important to understand the differences. It is important to understand the differences between MERV and CADR ratings in order to make the best decision. MERV ratings measure the effectiveness of the filter in removing particles. There are filters with MERV ratings between one and twenty. Filters with higher MERV ratings remove finer particles. The MERV rating is important when you are looking for a filter to fit your home.

The MERV rating is an important metric to consider when selecting an air filter. This rating is a measure of the air filter’s ability catch particles of various sizes. MERV 1 filters can trap bacteria and sneeze particle. The MERV 1-12 filters trap insecticide dust, pet hair, and other microscopic allergens. They can capture particles as small as 1 micron.


A CADR is a measure for particle filtration efficiency. It is used to compare different air filters. CADR measures three types of particles: pollen and tobacco smoke. The higher the CADR, the faster the filter removes the particles. If the CADR of two air filters is the same, their filtration performance is comparable. High CADRs may not be possible because different types and types of particles require different amounts airflow.


HEPA air filters trap dirt and dust particles in one of three ways. Some particles crash into the filter’s fibers, while others flow along in the airstream and are caught randomly. This process is called Brownian motion. The probability of interception is lower for smaller particles, but higher-quality particles are more likely to be caught by the filter. Both methods are effective at reducing indoor air pollution. HEPA filters can trap particles as small as 0.3 microns, depending on the size.


Electrostatic air filters capture tiny particles in the air. These filters can capture dust, pollen and pet dander as well as shed skin cells. Some filters can remove oil droplets from cooking. This technology is ideal for allergy sufferers who want their home to be as dust-free and clean as possible. If you have allergies, electrostatic air filters can help you breathe easier. You can also use them to protect your family from airborne viruses.


A pleated air filter is a type of filter that provides greater surface area for trapping contaminants than a non-pleated one. They are often found in HVAC systems of businesses and industrial settings, and can dramatically improve air quality. These filters are designed to be disposed of when they’re clogged, so they’re safe for the environment and for your HVAC unit. Pleated filters generally have a MERV rating of seven to thirteen.
