So here we are around nine months into this covid deal, and things are getting more unrealistic by the day.
We are hearing, but don’t have proof, that municipalities and other governmental orgs are requiring MERV 13 filters for buildings. Which brings us to a couple of problems.
I run an HVAC distributor and we are getting lots of calls for MERV 13 filters. We represent four filter companies. Two aren’t taking orders for MERV 13 product and of the other two, our best lead time is 4-6 months. For those who want to wait, we are encouraging them to buy a years supply and just store them.
We are even having trouble getting our standard pleated MERV 10 product due to factory production slowdowns because of covid. So we are getting some of the shooting of the messenger by our customers, but we can handle that OK.
Why the long lead times? Besides the crushing demand, the same companies that make media for masks, make media for MERV 13 filters. You can guess where priority is right now. Also, nobody has told me if the filters, presumably loaded with covid, will be someday declared a hazardous waste by OSHA, making their changeout completely ridiculous. Not to mention that MERV 13 filters create enormous amounts of static pressure, which will be terrible for a lot of systems, especially older ones. There are already rumblings of certain equipment manufacturers engineering departments getting ready to go to war with the authorities mandating these filters, and declaring “no warranty” on equipment failure due to lack of return air and MERV 13 filters putting their equipment out of engineering spec. This is super fun.
We have been recommending for a long time that people use standard pleats in combination with a bipolar ionizer or UV product, both of which in the past few months have received covid killing certification. We are hoping this MERV 13 train isn’t fully out of the station just yet and that everyone will start to get a bit more realistic. But since it is 2020 we aren’t expecting much.
