Understanding MERV Ratings and Air Filters

Air filters are an essential part of keeping your home clean and healthy. They help to remove dust, pollen, pet dander, and other airborne particles from the air, improving air quality and reducing the risk of allergies and other respiratory illnesses. But with so many different types of air filters on the market, it can be difficult to know which one is right for you. One important factor to consider when choosing an air filter is the MERV rating.

In this article, we'll explain what MERV ratings are, how they work, and how to choose the right filter for your home.

What is a MERV Rating?

MERV stands for Minimum Efficiency Reporting Value. It is a rating system used to measure the effectiveness of air filters in removing particles from the air. The higher the MERV rating, the more efficient the filter is at capturing particles. The ratings range from 1 to 16, with 1 being the least efficient and 16 being the most efficient.The MERV rating system was developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE).

It is based on a particle size range from 0.3 microns to 10 microns. A micron is one-millionth of a meter, so 0.3 microns is about 1/300th the width of a human hair.

Types of Air Filters

There are several different types of air filters available on the market today. The most common types are fiberglass, pleated paper, and HEPA (High Efficiency Particulate Air) filters. Fiberglass filters are the least expensive option but they are also the least effective at capturing particles.

Pleated paper filters are more effective than fiberglass but still not as effective as HEPA filters.HEPA filters are considered to be the most effective type of air filter available. They are rated at MERV 16 and can capture particles as small as 0.3 microns in size. This makes them ideal for removing dust, pollen, pet dander, mold spores, and other airborne particles from your home.

Choosing the Right Filter

When choosing an air filter for your home, it's important to consider both your budget and your needs. If you have allergies or asthma, you may want to invest in a higher-MERV filter such as a HEPA filter to ensure that you're getting the best possible air quality in your home.

If you don't have any specific health concerns, then a lower-MERV filter such as a pleated paper filter may be sufficient.It's also important to consider the size of your filter. Most air filters come in standard sizes such as 16x25x5 or 16x24x1.If you have an older furnace or air conditioner, you may need to purchase a custom filter or cut-to-fit air filter such as a Filter King or BestAir filter.

The Impact of Air Filters on COVID-19

The novel coronavirus (COVID-19) has highlighted the importance of good air quality in our homes and workplaces. According to the Centers for Disease Control and Prevention (CDC), airborne transmission of SARS-CoV-2 (the virus that causes COVID-19) is possible through aerosol particles and respiratory fluids. This means that having an effective air filtration system in place can help reduce the risk of transmission.

High-MERV filters such as HEPA filters can help capture these particles from the air before they have a chance to spread throughout your home or workplace. In addition to using an effective air filter, it's also important to practice good hygiene habits such as washing your hands regularly and wearing a face covering when in public.

Conclusion

Air filters play an important role in keeping our homes clean and healthy. When choosing an air filter for your home or workplace, it's important to consider both your budget and your needs.

The higher the MERV rating, the more efficient the filter is at capturing particles from the air. HEPA filters are considered to be the most effective type of air filter available and can help reduce the risk of airborne transmission of SARS-CoV-2 (the virus that causes COVID-19). In addition to using an effective air filter, it's also important to practice good hygiene habits such as washing your hands regularly and wearing a face covering when in public.Taking care of our mental health during this time is also essential for our overall wellbeing. Taking time for yourself each day can help reduce stress levels and improve overall mental health.
