Frequently Asked Question

A MERV 11 filter is a mid-range air filter, suitable for most residential and commercial buildings. It is ideal for households with pets or mild to moderate allergies or asthma. The MERV 11 filter is capable of trapping 85% of micron-sized airborne particles, which helps to improve indoor air quality and maintain the efficiency of the HVAC system. If you don't have any special needs, then a MERV 8 filter is usually sufficient.

The only standardized filter rating system is MERV, which stands for “minimum efficiency reporting value”. Developed by the American Society of Heating, Refrigerating, and Air Conditioning Engineers, the rating scale indicates how effectively a filter can stop particles from entering your home. The higher the MERV rating, the better the filtration and the more the HVAC system needs to work to overcome the filter’s back pressure.

For residential and commercial use, MERV ratings 8 to 13 are best. MERV 4 to 6 are only suitable for industrial applications, while MERV 14 to 20 are used primarily in hospitals and laboratories. HEPA filters, which aren’t included in the MERV rating system, are equivalent to a MERV 17 to 20 rating. Lastly, there are other rating systems like MPR (Microparticle Rating) and FPR (Filter Performance Rating) but these are not independent consumer standards.

When it comes to choosing the right furnace filter for your home, there’s no one-size-fits-all answer. To ensure that you make the best choice for your specific needs, you must consider various factors such as price, size, brand, and, most importantly, the MERV rating.

MERV stands for Minimum Efficiency Reporting Value, which is a rating system from 1 to 16 used to indicate how well the filter can capture airborne impurities. A MERV rating of 1 indicates the lowest efficiency, and 16 indicates the highest. MERV 8 and MERV 11 are two of the most popular ratings for residential use, as they are effective at trapping a majority of airborne particles.

So, which is better — MERV 8 or MERV 11? A MERV 8 filter is more affordable and perfect for filtering out large particles, but won't be as effective at capturing odors or small particles as a MERV 11 filter. MERV 11 filters are more expensive, and need to be replaced more often due to clogging, but can effectively reduce odors and capture small particles.

For the homes located in a polluted area, or those with pets or family members with allergies, a MERV 11 filter is the best choice. But if you don't fit into either of those categories, then a MERV 8 filter should suffice.

It is essential to keep in mind that the MERV rating for a filter is its minimum performance, and choosing the right one for your home will ensure that your HVAC system is functioning optimally.

Are you wondering what the difference is between MERV 11 and 13 furnace filters? Let us break it down for you.

MERV 11 filters are the most popular among residential users, and they can trap the majority of harmful contaminants in the air – this includes pollen, dust, lint, mold, dust mites, smoke, pet dander, and smog.

On the other hand, a MERV 13 filter is capable of capturing all of the particles that the 11 can, plus bacteria and viruses. This is due to its higher efficiency of particle arrestance (98%) compared to the 11 (90%).

When it comes to which one is better, it really depends on your needs. A MERV 11 is good enough for those living in moderately polluted areas, or those with mild allergies. But if you're in a heavily polluted area, or suffer from severe allergies/asthma, or own multiple pets – then the MERV 13 is the way to go.

No matter which rating you pick, it's important to remember to replace your filter periodically. Doing so will help ensure that your furnace remains in top shape for years to come.

MERV 11 air filters are more effective than MERV 8s, trapping smaller particles like pet dander, dust mites, auto-emissions and lung-damaging dust. This makes them a great choice for households with pets or those wanting improved air quality. It's also the most popular air filter option.

If you're looking for a middle-ground between MERV 8 and 13, MERV 11 is the perfect option. It’s more efficient than the 8, but cheaper than the 13, and won’t put extra pressure on your furnace due to its less dense material. Your furnace will last longer and your air will be healthier!

Before settling on a MERV rating, check your furnace's manual or info stickers to see what its max MERV rating is. Selecting an air filter with a higher rating than your system can handle can cause your furnace to work harder, increasing the risk of a breakdown.

MERV ratings are a standard that measure how well air filters work. The higher the rating, the finer the filtration, meaning fewer allergens, dust, and other contaminants can get through. Filters are tested for things such as pollen, dust mites, mold spores, pet dander, bacteria, tobacco smoke, and more.

Merv 8, 11, and 13 filters should be changed at least every three months. This is to ensure that your system doesn't get clogged, reducing its efficiency or damaging it. However, changing your filter every two months will give you even better filtration and healthier air in your home.

In short, the more often you change your MERV 11 filter, the better. A recommended minimum is every three months, but changing it every two months is even better for your home's air quality.
