Is merv 13 too high for residential?

Filters within a merv rating of 17 to 20 are almost never needed in a residential home. A merv rating of 13 to 16 is considered hospital-level air quality, so your home is unlikely to need more than that. Good luck with your decision to use higher MERV filters in the future. Of course, they're not a bad thing.

Reducing the amount of dirty particles for the air in your home is a very common request. It's just important to make sure that the rest of the system is configured to handle the biggest restriction that filters create. In general, filters with higher merv ratings capture higher percentages of particulates as well as smaller particles. And MERV-13* is practically where you want to be.

If your home's HVAC system isn't capable of handling MERV 13, opt for a filter with the next highest possible rating. So, while the MERV rating is over 13, it will be best to avoid going higher in your household. It turns out that sometimes, due to the unintended consequences of high MERV filters, the cure is worse than the problem. When you have a filter of merv 13 and above, it is more similar to the material you would find in an n95 dust mask.

By the way, surgeries have a variety of merv filters and HVAC systems use merv filters; in both cases, they do not use fiberglass. Mcmaster Carr manufactures the MervMcMaster Carr manufactures the Merv-15 airbags that some universities are testing for face masks. This merv filter is questionable, as it will actually be effective for this use, since I understand that they need an electrostatic charge that they do not receive when placed in a mask. Not all filters have a Merv.

Not all filters have a Merv rating %26, many of them are purchased at big box stores. However, high MERV filters offer superior filtration, trapping everything from construction dust and tobacco smoke to bacteria. I'm wearing a MerVi cape. I am using a layer of Merv 1900 3M Filtrete on my mask (I made the mask as a cover so I could remove the filter to wash it).

I just watched an FB video from AI I just saw an FB video of a British doctor who says that vacuum bags are NOT safe for masks, since they contain fiberglass, which is very bad for breathing (and worse when the bags have been cut to make inserts) IF, however, the MERV air filters are, as I am reading, made of polyester and cotton, they should be safe. Keep in mind that as the MERV rating increases, the filter becomes more restrictive and more pressure and energy will be needed to push air through it. Home Energy published an article by Dave Springer of Davis Energy Group at the time, about the pressure drop and energy use of various MERV filters.
