Using an air filter with a MERV rating that is too high is just as bad as using one that is too low. Air filters with higher MERV values can filter more, but the thickness of the filter material can restrict airflow. If you want to remove more material 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, but it also adds more resistance.
Higher MERV filters have greater resistance. The short answer is yes, but it's not really a problem, except in extreme circumstances. Most modern air conditioning systems have no problem operating with higher MERV filters, which is why millions of homeowners rely on them. The main risk of high-efficiency air filters comes from the fact that they are not modified for long periods.
of time. If you take care of changing the filters, it's unlikely that you'll have problems related to the filters in your air conditioning system. 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. A MERV 8 carbon filter will filter more than enough dust and allergens and will filter dozens of toxic gases that will pass directly through a MERV 13 filter.
A MERV 13 filter a MERV 13 filter is most likely to help if the goal is to prevent droplets from passing through him. 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. Low-efficiency filters are usually inside MERV 1-4 and high-efficiency filters are inside MERV 13 and beyond. 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.
In addition, a MERV 12 filter that is only 1 (one inch) thick is likely to be more restrictive than a 4 (four) MERV 12 filter inches) thick. A MERV 11 filter only needs to stop 20% of 0.3 to 1.0 micron particles (three to ten times larger than a COVID-19 particle), a MERV 12 only needs to stop 35% of particles smaller than 0.3 microns, and a MERV 13 only needs to stop half. However, if not, this information will answer the question “what is the MERV classification? What is the best MERV rating for my oven or air controller? and similar introductory questions. By the way, surgeries have a variety of merv filters, and HVAC systems use merv filters; in both cases, they don't use fiberglass.
The Merv 16 would be the best The Merv 16 would be the best, since it would filter 95%. There's a YouTube video showing how to make your own N95 with a filter Wednesday 16.
