A higher MERV rating means greater resistance, which in turn leads to less airflow. This is an important factor to consider when researching air conditioning systems, as airflow is essential for the performance and longevity of your furnace or air controller. It is also key to a comfortable home. The higher the filter rating, the smaller the particles it will capture and the higher the percentage of particles captured.
Low-efficiency filters are usually within the MERV 1-4 range, while high-efficiency filters are those of the MERV 13 and higher. The MERV scale is not linear; the difference between a MERV 6 and a MERV 8 is almost double in terms of the percentage of particles captured. It is important to note that as the MERV rating increases, the filter becomes more restrictive and more pressure and energy will be needed to expel air. Using an air filter with a MERV rating that is too high can be just as detrimental as using one that is too low. Air filters with higher MERV ratings may filter more, but the thickness of the filter material may restrict airflow.
This can reduce comfort, increase energy use, and accelerate the wear and tear of air conditioning components. In particular, using an air filter with a MERV rating that is too high can damage the compressor, heat exchanger, and air conditioner coil. This comparison chart helps highlight the differences between the MERV 8 and MERV 11 filters to make it easier to decide which one will work best. Every air filter has its pros and cons, but both MERV 8 air filters and MERV 11 air filters are suitable for residential use. A MERV 8 carbon filter will more than enough filter dust and allergens and filter dozens of toxic gases that will pass directly through the MERV 13 filter.
If you're concerned about the effects of inhaling fine air particles, that's another reason to choose a MERV 11 air filter over a MERV 8 air filter. If you're trying to choose between a MERV 8 air filter and a MERV 11 air filter, here's what you need to know. If you buy to wash an alcohol, you could very well be creating some strange, weird and fun chemicals, unless you're just washing cotton, so I would only use sunlight to disinfect them, even that could break the tall Merv filters a little and release an unwanted, perhaps dangerous, chemical that degassing an activated carbon filter with high Merv could be your best option between you and any other exotic chemical action you're doing. By the way, surgeries have a variety of merv filters and HVAC systems use merv filters; in both cases, they don't use fiberglass. Finally, peace of mind is priceless and if people think that a high MERV filter would provide that, they should do so with the exception that they must replace dirty filters often enough - 26%, it could be one or two weeks depending on the MERV classification, the effective area of the filter and the amount of particles that enter your house. Raising just three MERV rating levels can be a smart decision that makes the air cleaner or a harmful option for the entire air conditioning system considering the air flow capabilities of the MERV 8 versus the MERV 11. One thing to keep in mind is that the MERV 11 air filter may need to be changed a little more frequently than the MERV 8 air filter. The latter cannot filter out fine particles like its higher rated counterpart.
When it comes to choosing between an MERV 8 or MERV 11 air filter for your home or business, there are several factors to consider. The most important factor is airflow: as you increase your MERV rating, you also increase resistance which can lead to reduced airflow. This can cause discomfort in your home or business as well as increased energy costs due to inefficient operation of your HVAC system. Additionally, using an air filter with too high of a rating can cause damage to your compressor, heat exchanger, and other components due to restricted airflow.
On the other hand, using an air filter with too low of a rating can also be detrimental as it won't capture enough particles from your indoor environment. It's important to find a balance between capturing enough particles while still allowing adequate airflow for efficient operation of your HVAC system. The comparison chart between MERV 8 and MERV 11 filters can help you decide which one will work best for your needs. Both are suitable for residential use but if you're concerned about inhaling fine particles then it may be worth investing in a higher rated filter such as a MERV 11.
However, keep in mind that these filters may need to be changed more frequently than lower rated ones due to their increased thickness which can restrict airflow. In conclusion, when choosing between an MERV 8 or MERV 11, it's important to consider both particle capture rate as well as airflow restrictions. A higher rated filter may provide better particle capture but may also reduce airflow which can lead to discomfort in your home or business as well as increased energy costs due to inefficient operation of your HVAC system. It's important to find a balance between capturing enough particles while still allowing adequate airflow for efficient operation of your HVAC system.
