I sent the up-to-date Heating plus A/C filters back because they had a unusual chemical smell to them

There is a particular online marketplace that I use for a huge portion of our essential purchases.

I love their several-day delivery offers, low prices, and self-explanatory return process. The last point is key, because a contractor that covers a volume of business that huge is bound to make mistakes. You have to let your clients make returns if they end up with a terrible product. Otherwise you’re going to have agitated clients on your hands that leave scathing reviews about “cash and time wasted,” which seem to be the recurring words that drone on from the chorus of complaints. I have had mostly good experiences until the pandemic started, then the huge increase in volume and a lack of quality employees made their customer service drop in a noticeable way. Recently I ordered what I believed to be high quality Heating plus A/C filters with a massively high MERV rating of 14 and a layer of charcoal crystals on 1 side. The comparable filter from 3M at the hardware store is only MERV 12 and costs more per unit. Unfortunately, these filters had a unusual chemical smell so I put them next to our smart air cleaner which can track VOC levels. I was speechless when I saw the results. It tracked a noticeably increase in VOC levels while the comparable 3M filter had a VOC level of 0. I feel terrible for people who use this air filter in their Heating plus A/C plan and then have to deal with the horrible VOCs that are affixed to the filter itself and then dealing with the VOCs getting into the Heating plus A/C plan at large.
