Restricted airflow can reduce comfort, increase energy use, and accelerate wear and tear on HVAC components. In particular, using an air filter with a MERV rating that is too high can damage the compressor, heat exchanger, and air conditioning coil. If your boiler's MERV rating is too high, it can force it to work too hard and leave it vulnerable to damage. In addition, you may not get the air velocity needed to reach every part of your home, which will cause inconsistencies in the temperature.
If you want to remove more things from the air, you can use a filter with a different material. The pores of these filters are much smaller, allowing the filter to trap more contaminants from the air stream and, at the same time, adding more resistance. Taller MERV filters have greater strength. Usually, a filter with a higher MERV rating will reduce airflow.
However, there are many other factors at play, such as the size of the filter and the type of fan motor in your HVAC system. Good luck with your decision to use higher MERV filters in the future. Of course, they are not a bad thing. Reducing the amount of dirty particles in the air in your home is a very common request. It's just important to ensure that the rest of the system is configured to handle the increased restriction created by filters.
For example, hospitals, nuclear power plants, and other demanding environments often need air filters with a MERV rating of 16 to 20. If you want to use pleated filters and taller MERV filters, the only safe way to do this is to ask a professional to install a 5- to 6-inch medium filter. The Merv 16 would be the best The Merv 16 would be the best, as it will filter 95%. There's a YouTube video showing how to make your own N95 with a Merv 16 filter.
A MERV 13 filter will be like a MERV 13 filter and will probably help if the goal is to prevent droplets from passing through it. Increasing a filter to increase a filter to a higher MERV can increase delta P throughout the filter. This is why it is not recommended to use a MERV 20 air filter in homes that are not designed to withstand this level of filtration. Finally, I say that peace of mind is priceless and that, if they consider that a high MERV filter would be sufficient, they should do so with the exception that they must replace dirty filters often enough and that may take a week or two, depending on the MERV classification, the effective area of the filter and the amount of particles that enter your home. While the air filter is designed to control the amount of unwanted air particles that enter your home, your filter's MERV rating aims to show you which filter is best suited for your home.
In fact, researchers have found that while high MERV filters can cause a pressure drop, the impact is not significant unless the filter is loaded with dirt. Buy to wash an alcohol YouBuy by washing an alcohol, you could very well be creating some strange and fun chemicals, unless you are only washing cotton, so I would use sunlight to disinfect them, even that could break down the high Merv filters a little and release an unwanted, perhaps dangerous chemical, degassing a high Merv activated carbon filter could be your best option between you and any other type of exotic chemical action that is taking place. A MERV 8 filter should be sufficient for homes with few occupants and no pets, while homes with more people and some pets need a MERV 11 filter. Yes, I'm looking for the same thing. Yes, I'm looking for the same answer about using a merv13 pleated air conditioning filter as part of a mask.
Air filters below the MERV 5 will not be enough to maintain good air quality inside your home, while those above the MERV 13 could compromise the performance of your home's HVAC unit. MERV 11 air filters aren't too restrictive for most systems, as long as you remember to change them regularly. In addition, air filters high in MERV that contain pleats create a much larger surface area for air to blow through, which can improve airflow and reduce stress on the system.
